Harvard study shows that wind power could cause more warming than coal

As reported by James Temple in the MIT Technology Review:

A new study by a pair of Harvard researchers finds that a high amount of wind power could mean more climate warming, at least regionally and in the immediate decades ahead. The paper raises serious questions about just how much the United States or other nations should look to wind power to clean up electricity systems.

The study, published in the journal Joule, found that if wind power supplied all US electricity demands, it would warm the surface of the continental United States by 0.24 °C. That could significantly exceed the reduction in US warming achieved by decarbonizing the nation’s electricity sector this century, which would be around 0.1 °C.

“If your perspective is the next 10 years, wind power actually has—in some respects—more climate impact than coal or gas,” coauthor David Keith, a professor of applied physics and public policy at Harvard, said in a statement. “If your perspective is the next thousand years, then wind power is enormously cleaner than coal or gas.”

The core problem is that wind turbines generate electricity by extracting energy out of the air, slowing down wind and otherwise altering “the exchange of heat, moisture, and momentum between the surface and the atmosphere,” the study explains. That can produce some level of warming. The new research suggests we can’t put too many turbines to close together or the whole group become far less efficient. That means we need 5 – 20 times as much land as previously thought (at least as thought by academics) Read more

Why You Should Vote NO on Arizona Proposition 127, the renewable energy mandate (Update)

Proposition 127 is very bad policy because: 1) wind and solar generation of electricity are both expensive and unreliable; 2) wind and solar generation can be dangerous to wildlife, human health, and the environment; and 3) the perceived need for more wind and solar generation is based on the false assumption that carbon dioxide emissions are a major cause of global warming.

The method of generating electricity should not be determined by one-size-fits-all government mandates, but rather by local market conditions and resources.

In the following summary I explain the problems with renewable energy. More background is available in the references at the end of this post.

Arizona proposition 127, dubbed “The Clean Energy for a Healthy Arizona Amendment” will amend the Arizona Constitution to require affected electric utilities generate at least 50% of their annual retail sales of electricity from renewable energy sources by 2030. The amendment defines renewable energy sources to include solar, wind, small-scale hydropower, and other sources that are replaced rapidly by a natural, ongoing process (excluding nuclear or fossil fuel). Distributed renewable energy sources, like rooftop solar, must comprise at least 10% of utilities’ annual retail sales of electricity by 2030. The Amendment allows electric utilities to earn and trade credits to meet these requirements. (Read full text)

Arizona currently produces half of its renewable energy from hydropower generated at the large dams on the Colorado River, but, according to the proposed amendment, this electricity is not to be counted toward the 50% mandated goal. According to the Energy Information Administration, power plants in Arizona generate more electricity than the state consumes, and Arizona generating stations supply electricity to consumers throughout the southwest.

 

Expensive:

Promoters of proposition 127 claim that (based on computer modeling) more renewable energy generation will decrease the price of electricity. The computer model claims that “average electricity bills in 2030 would be three dollars a month lower if Arizona pursues a high-renewables future, and five dollars a month lower in 2040.”

Contrary to claims of proposition promoters, real-world experience shows that the price of electricity can triple as the percentage of wind and solar generation increases. According to data from the U.S. Energy Information Administration, Arizona’s existing 7 percent renewable power mandate (on its way up to 15%) cost the average Arizona household $304 in higher electricity charges in 2017. At 50 percent renewables, as required by prop. 127, that could rise to an additional $2,179 per year compared to present electricity costs. (Source: The Heartland Institute) Higher electricity rates disproportionally impact the poor. (See this story)

My own electric bill from Tucson Electric Power is running at the rate of an extra charge of $230 per year due to the renewable energy mandate. A curious thing: These charges used to be listed on the bill as “Green Energy Charges” but since March, 2017, they are listed merely as “Surcharges.”

Electricity produced by wind and solar turns out to be much more expensive than electricity produced from coal and natural gas. That is mainly because wind and solar are unreliable, they can’t respond to demand. Therefore they need nuclear or fossil fuel generated electricity as backup which causes the fossil fuel plants to run inefficiently which is more expensive (and produces more carbon dioxide).

Europe has been a world leader in using wind and solar energy. The price, however, is high. Real operational data show that the more installed solar and wind capacity per capita a country has, the higher the price people pay for electricity. (Source) In some European countries electricity prices are triple the average cost in the U.S. Ironically, carbon dioxide emissions in those countries are rising while in the U.S. emissions are decreasing. Also ironically, according to the New York Times, renewables are helping to push nuclear power, the main source of zero-emissions electricity in the United States, into bankruptcy.

Australia has been flirting with replacing coal generation with renewables. Australian engineers warn 55% renewables will add $1400 to electricity bills, an 84% increase in electricity rates. (Source) The state of South Australian generates about 50 percent of its electricity from wind and solar power. South Australia’s consumer electricity prices are the highest in the world and electric reliability is one of the worst in the developed world. (Source)

California: According to Environmental Progress, a pro-nuclear advocacy group:

Between 2011 and 2017, California’s electricity prices rose five times faster than they did nationally. Today, Californians pay 60 percent more, on average, than the rest of the nation, for residential, commercial, and industrial electricity. California’s high penetration of intermittent renewables such as solar and wind are likely a key factor in higher prices. (LinkHad California spent an estimated $100 billion on nuclear instead of on wind and solar, it would already have had enough energy to replace all fossil fuels in its in-state electricity mix according to a new analysis by Environmental Progress.

study by the left-of-center Brookings Institution found replacing conventional power with wind power raises electricity prices 50 percent, and replacing conventional power with solar power triples electricity costs.

From the Brookings report:

Costs are much higher for three reasons. First, the cost per MW [megawatt] of capacity to build a wind or solar plant is quite high (and much greater than that of a gas-fired plant). The cost per MW of solar capacity is especially high. Reductions in the cost of solar-voltaic panels have reduced the cost of building a solar plant by 22 percent between 2010 and 2012, but further reductions are likely to have a lesser effect because the cost of solar panels is only a fraction of the total cost of a utility-scale solar plant.

Second, a wind or solar plant operates at full capacity only a fraction of the time, when the wind is blowing or the sun is shining. For example, a typical solar plant in the United States operates at only about 15 percent of full capacity and a wind plant only about 25 percent of full capacity, while a coal plant can operate 90 percent of full capacity on a year-round basis.

Third, the output of wind and solar plants is highly variable—year by year, month by month, day by day and hour by hour—compared to a coal-fired plant… Thus more than six solar plants and four wind plants are required to produce the same output with the same degree of reliability as a coal-fired plant of the same capacity.

The Institute for Energy Research (IER) is a not-for-profit organization that conducts intensive research and analysis on the functions, operations, and government regulation of global energy markets. They conclude: “As a means of producing useful electrical power, wind and solar are very expensive generating technologies because of their low capacity factors and because of their non-dispatchability and intermittency.” (Source)

It has been proposed that the intermittency problem with wind and solar can be solved by battery storage. But an MIT Technology Review article says that would be too expensive: “The $2.5 trillion reason we can’t rely on batteries to clean up the grid: Fluctuating solar and wind power require lots of energy storage, and lithium-ion batteries seem like the obvious choice—but they are far too expensive to play a major role.” The $2.5 trillion battery system would provide just 12 hours of storage for the entire U.S. (Link)

Dangerous:

Utility scale wind and solar installations require vast expanses of land that affect local habitats. Wind turbines chop up birds and bats, including endangered species. Solar installations burn up birds and other flying animals. Low frequency sound from wind turbines causes a variety of human ailments. The manufacturing and disposal of solar panels put dangerous chemicals into the environment. For example, many PV solar panels rely on polysilicon being manufactured in large quantities and at high quality. A byproduct of polysilicon production is silicon tetrachloride, a highly toxic substance that poses a major environmental hazard. Wherever silicon tetrachloride is dumped, the land becomes totally infertile. A major environmental cost of photovoltaic solar energy is toxic chemical pollution (arsenic, gallium, and cadmium) and energy consumption associated with the large-scale manufacture of photovoltaic panels. Does that sound like “clean energy”?

recent study shows that solar modules cause more greenhouse gas emissions than modern coal power plants. It turns out that because of the emissions of extraordinarily potent greenhouse gases nitrogen trifluoride and sulfur hexafluoride and energy requirements of manufacturing solar modules, solar energy ends up being worse for the climate than burning coal.

(See references 5 & 6)

Another danger is that proposition 127 is intended to be an amendment to the Arizona Constitution rather than a statute. It will therefore be much harder to repeal once its utter folly is realized.

The false assumption:

The push for renewable energy, especially wind and solar generation, is based on the contention that carbon dioxide emissions from burning fossil fuels are a significant cause of global warming.

This claim is not based on physical evidence but only upon garbage-in, garbage-out computer models, the results of which diverge widely from observations. The U.N. Intergovernmental Panel on Climate Change (IPCC) is the major promoter of the human-caused global warming scare. Yet, in five major reports, the IPCC does not provide any physical evidence that carbon dioxide emissions play a significant role in global warming. I have asked several university climate scientists who support the claim to cite supporting physical evidence. Although they are alleged experts in the field, they could not cite any physical evidence. They devolve to computer modeling. On the other hand, there are several lines of physical evidence that show carbon dioxide emissions do not enhance the dread greenhouse effect. (See references 1, 2, 3, 4, 8 & 9) Many scientific studies present physical evidence showing that carbon dioxide is but a bit player among the many factors influencing climate change. (See these references: link)

A report from the Science and Public Policy Institute estimates the temperature savings theoretically obtained by stopping all carbon dioxide emissions for each state and for the U.S. as a whole. According to SPPI, if Arizona stopped all carbon dioxide emissions, it would theoretically prevent a temperature rise of 0.0014°C by 2050 and 0.0029°C by 2100. If the U.S. stopped all carbon dioxide emissions, it would theoretically prevent a temperature rise of 0.172°C by 2100. (Link to report) Do you think that’s worth the higher electricity prices and disruption of the electric grid?

In the entire geological history of the planet, there has been no known linkage between CO2 and temperatures other than that temperature controls the solubility of CO2 in the oceans. (See reference 8) The war on carbon dioxide tries to cure a problem that does not exist.

Generating more electricity from solar and wind is just a very expensive exercise in political correctness that will have little impact on carbon dioxide emissions, but a big impact on your wallet, and an adverse impact on electric grid stability and the environment. (See reference 7) If you really want low/no emissions generation of electricity, we should invest in more nuclear generation which is always there when you need it.

“The whole aim of practical politics is to keep the populace alarmed and hence clamorous to be led to safety by menacing it with an endless series of hobgoblins, all of them imaginary.” – H. L. Mencken

Climate Madness 12, California is craziest

Climate on this planet has been changing all by itself for about four billion years. Now, either through ignorance or presumed political advantage, some politicians think they can stop climate change. That policy represents the real danger of global warming. Their magic formula is to stop carbon dioxide emissions from burning fossil fuels. Instead, they promote generation of electricity mainly from utility-scale solar or wind installations. As I have written before, solar and wind generation cannot respond to demand and are ultimately very unreliable and very expensive for ratepayers. Solar and wind would not exist without mandates and subsidies.

(See Vote NO on Arizona proposition 127 the renewable energy mandate and the references in that article.)

The United Nations Intergovernmental Panel on Climate Change (IPCC) has produced five major reports none of which contain any credible proof that carbon dioxide emissions are the principal cause of global warming. In the third report, the IPCC admits: “In climate research and modeling, we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that the long term prediction of future climate states is not possible.”

Following are some of the most recent manifestations of climate madness. We start with California climate craziness.

Climate Activists Want Gov. Brown To Shut Down Fossil Fuel Production In Calif.

By John Glennon

On the heels of Judge William Alsup’s decision to dismiss San Francisco’s and Oakland’s climate change lawsuits, local California officials are turning to new symbolic tactics, including pressuring Governor Jerry Brown ahead of his Global Climate Action Summit.

A group of 150 local elected officials sent an open letter to Governor Jerry Brown last week to chastise him for not completely shutting down fossil-fuel production in the state.

In the letter, the local officials demanded that Governor Brown pursue a meaty list of harmful and unrealistic policies:

“Recognizing that we are in a climate emergency, as you have rightly done, and given the grave public health and environmental justice consequences of fossil fuel production in California, we respectfully urge you to make a new statewide commitment and lay out a plan for California to achieve the following:

“End the issuance of permits for new fossil fuel projects, including permits for new oil and gas wells, infrastructure for fossil fuels, and petrochemical projects in California.

“Design a swift, managed decline of all fossil fuel production, starting with a 2,500-foot human health buffer zone around all occupied structures, public parks, and farms to protect public health and vulnerable communities.

“Commit the state to 100% clean, renewable energy, starting with significant investments in disadvantaged communities and areas that are already suffering the most from the negative impacts of fossil fuel extraction.” Read more Update: By a vote of 44 to 33, lawmakers in the California State Assembly passed SB 100, a bill that calls for the state to transition to emissions-free electricity production in less than three decades. Under the guidelines of the legislation, California must obtain 60 percent of its energy from renewable sources by 2030. The state’s electricity generation must be completely carbon free by 2045. The bill still needs to pass the CA senate. (Source)

 

Analysis: California’s Solar Panel Mandate Lowers CO2 Emissions by 0.32%

By Elizabeth Harrington

California will mandate solar panels on new homes out of concern for climate change, a policy that will raise prices in the most expensive home market in the country and does little to decrease the state’s carbon footprint. MIT reports: “California estimates that the new rule will cut emissions by 1.4 million metric tons over three years, which is a small fraction of the 440 million tons the state generated in 2015.” Emissions would be reduced by 0.32 percent. Read more

 

Utility blaming climate change, not its fallen power lines, for California wildfires

By Thomas Lifson

My cable news viewing is frequently interrupted by commercials instructing Northern Californians that climate change is responsible for the state’s current ordeal with multiple large wildfires. This is a contemptible attempt by utilities to evade responsibility for the damages caused by their power lines located near combustible forests (made much more combustible by policies preventing harvesting “old growth” and clearing deadwood). Read more

 

California and the L. A. Times latest climate alarmist absurdities

by Larry Hamlin

The Times article fails to note the UN IPCC conclusions regarding the undisputed inadequacy of “climate models” which it described in its AR3 climate report as “In climate research and modeling, we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that the long term prediction of future climate states is not possible.”

The Times article provides speculative alarmist “model driven” assertions about future coastal sea level rise contained in the state’s report which it characterizes as “Until recently, scientists and state policymakers worked with a projection that sea level rise by the end of this century could amount to about 5.48 feet in California under the worst case scenario. But the latest reports and state policies are now accounting for the extreme possibility that sea level rise could exceed 9 feet.”

Of course as is always the case with these wild and absurd sea level rise claims actual California coastal sea level rise measured NOAA tide gauge data with records going back more than 100 years is completely ignored by the state and L. A. Times because it shows absolutely no coastal sea level rise acceleration occurring at the states coastal locations with sea level rise occurring at steady rates between about 3 to 8 inches per CENTURY. Read more

REPORT: How The Billion-Dollar-A-Year Climate Industry Weaponized State Attorneys General

by Michael Bastasch, Daily Caller

A new report based on documents collected over two-and-a-half years through open records requests outlines an “elaborate campaign” by the “billion-dollar per year climate industry” to weaponize state attorneys general (AGs) in service of the global warming agenda.

That campaign culminated in what the report labels “law enforcement for hire” because it allows political donors to pay for state prosecutors “in the service of an ideological, left-wing, climate policy agenda.”

“It represents private interests commandeering the state’s police powers to target opponents of their policy agenda and to hijack the justice system as a way to overturn the democratic process’s rejection of a political agenda,” Competitive Enterprise senior fellow Chris Horner wrote in his report, a copy of which was given to The Daily Caller News Foundation. Read more

Smart meters: Data spy or key energy device

The United States Court of Appeals for the Seventh Circuit has handed down a landmark ruling, stating that data collected by smart meters is protected by the Fourth Amendment.

The court pointed out that the smart devices, in fact, collect information for a deeper insight which can be obtained by thermal imaging tech. Furthermore, the court held that residents have a reasonable expectation of privacy and government access of this data constitutes, in essence, a search.

Jamie Williams, staff attorney at the Electronic Frontier Foundation, said: “The Seventh Circuit recognized that smart meters pose serious risks to the privacy of all of our homes, and that rotely applying analog-era case law to the digital age simply doesn’t work.”

This has shone the spotlight on whether or not smart meters can be used to spy on consumers. Through the collection of usage data at high frequencies (every five, 15 or 30 minutes), a clear picture can be garnered of activity occurring on the property.

Individual lifestyles can be examined, such as predicting daily routine, sleep patterns, meal times and periods away from the property. Read more

Vote NO on Arizona proposition 127 the renewable energy mandate

Arizona proposition 127, dubbed “The Clean Energy for a Healthy Arizona Amendment” has qualified for inclusion on the November ballot although it is still being challenged in court. If this amendment to the Arizona Constitution actually reaches the ballot it would, if passed, require affected electric utilities to provide at least 50% of their annual retail sales of electricity from renewable energy sources by 2030. The amendment defines renewable energy sources to include solar, wind, small-scale hydropower, and other sources that are replaced rapidly by a natural, ongoing process (excluding nuclear or fossil fuel). Distributed renewable energy sources, like rooftop solar, must comprise at least 10% of utilities’ annual retail sales of electricity by 2030. The Amendment allows electric utilities to earn and trade credits to meet these requirements. (Read full text)

Arizona currently produces half of its renewable energy from hydropower created by the large dams on the Colorado River, but, according to the proposed amendment, this electricity is not counted in the 50% mandate. According to the Energy Information Administration, power plants in Arizona generate more electricity than the state consumes, and Arizona generating stations supply electricity to consumers throughout the southwest.

In my opinion, this amendment is very bad policy. It is stupid, dangerous, and expensive. In the following summary I explain. More background is available in the references at the end of this post.

Stupid:

The push toward renewable energy, especially wind and solar generation, is based on a false premise: the contention that carbon dioxide emissions from burning fossil fuels are a significant cause of global warming, and that global warming is dangerous. Utility scale wind and solar installations would not exist were it not based on this false assumption, mandates, and subsidies.

This claim is not based on physical evidence but only upon garbage-in, garbage-out computer models, the results of which diverge widely from observations. I have asked several university climate scientists who support the claim to cite supporting physical evidence. Although they are alleged experts in the field, they could not cite any physical evidence. On the other hand there are several lines of physical evidence that show carbon dioxide emissions do not enhance the dread greenhouse effect. (See references 1, 2, 3 & 4)

Dangerous:

Utility scale wind and solar installations require vast expanses of land that affect local habitats. Wind turbines chop up birds and bats, including endangered species. Solar installations burn up birds and other flying animals. Low frequency sound from wind turbines causes a variety of human ailments. The manufacturing and disposal of solar panels put dangerous chemicals into the environment.

new study shows that solar modules cause more greenhouse gas emissions than modern coal power plants. It turns out that because of the emissions of extraordinarily potent greenhouse gases nitrogen trifluoride and sulfur hexafluoride and energy requirements of manufacturing solar modules, solar energy ends up being worse for the climate than burning coal (assuming the greenhouse global warming hypothesis is valid). (See references 5 & 6)

Expensive:

Electricity produce by wind and solar turns out to be much more expensive than electricity produced from coal and natural gas. That is mainly because wind and solar are unreliable, they can’t respond to demand. Therefore they need nuclear or fossil fuel generated electricity as backup which causes the fossil fuel plants to run inefficiently which produces more carbon dioxide.

Europe has been a world leader in using wind and solar energy. The price, however, is high. The more installed solar and wind capacity per capita a country has, the higher the price people pay for electricity. In some European countries electricity prices are triple the average cost in the U.S. Ironically, carbon dioxide emissions in those countries are rising while in the U.S. emissions are decreasing. Also ironically, according to the New York Times, renewables are helping to push nuclear power, the main source of zero-carbon electricity in the United States, into bankruptcy.

 

Generating more electricity from solar and wind is just a very expensive exercise in political correctness that will have little impact on carbon dioxide emissions, but a big impact on your wallet and an adverse impact on electric grid stability and the environment.

Why replacing fossil-fuel generation of electricity with solar or wind is dangerous

Renewable energy for generation of electricity (solar and wind) is the politically correct panacea to fight the bogeyman of global warming. However, experience has shown that replacing electrical generation by fossil fuels with wind or solar generation makes the power supply unreliable and leads to electrical grid instability, much higher electricity costs, environmental problems, and very little decrease in carbon dioxide emissions. The renewable energy industry would probably not exist without mandates and subsidies. Fossil-fuel generated electricity responds to demand and is available 24/7; solar or wind generated electricity is not.

There is currently a campaign by the Arizona Corporation Commission to mandate that 50 percent of electricity be generated from renewable sources. This is very dangerous as noted below.

Experience from Europe shows that the more installed solar and wind capacity per capita a country has, the higher the price people pay for electricity. In some European countries, electricity prices are three times higher than the average price in the U.S., see:

https://wryheat.wordpress.com/2018/02/27/the-high-cost-of-electricity-from-wind-and-solar-generation/ 

Also, there is no physical evidence that carbon dioxide emissions from burning fossil fuels intensifies the greenhouse effect. On the other hand , there are several lines of physical evidence that such emissions do not enhance the greenhouse effect, the alleged cause of global warming:

Following are some articles on this issue. Perhaps these stories will convince Arizona voters and Arizona legislators of the foolishness of renewable energy mandates.

AZ Clean Energy Constitutional Amendment Would Shut down Nuclear Power in State

By H. Sterling Burnett, Heartland Institute

California hedge fund billionaire Tom Steyer is pushing a ballot measure in Arizona to amend the state’s constitution requiring utilities to get 50 percent of their electricity from favored renewable energy sources, such as wind and solar power, by 2030.

The Clean Energy for a Healthy Arizona, HCR 2017 increases the current renewable power mandate from its present requirement of 15 percent by 2025, in an attempt to reduce the carbon dioxide generated from electric power production in the state to fight climate change.

Effect on Nuclear Power

Arizona Public Service Company (APS), the owner of the Palo Verde Nuclear Generating Station (Palo Verde), warns if voters approve this constitutional amendment, its nuclear plant would have to close in six years instead of continuing to generate electricity for 27 years as its current operating license permits.

Palo Verde is the largest source of electric power in Arizona, providing 36 percent of the state’s electricity. By comparison, non-hydro renewables in Arizona, dominated by solar power, generate about 4 percent of the state’s electricity. Coal produces about 25 percent and natural gas about 30 percent of the state’s electric power.

Palo Verde just received a 20-year extension from the U.S. Nuclear Regulatory Commission to operate the plant until 2045. Attempting to build sufficient renewable power to take the place Palo Verde, as well as also replacing the electricity from coal-fired power plants in the state, which will also have to be closed prematurely, will require almost 30 times the amount of electricity from renewable sources as they produce now, to be online in less than 12 years.

APS officials say under the measure solar and wind development would produce more electric power than is needed during half the year when Arizonans are not using their air conditioners, with the oversupply forcing the closure of baseload nuclear and coal-fired power plants, which provide a constant flow of electricity. APS also says the cost of electricity would rise significantly if this measure passes. Read more ☼

Why Proposed Wind and Solar Power Projects Should Be Rejected Nationwide

by Alan Carlin

While USEPA is trying to reduce the number of regulations it has, the climate industrial complex (CIC) is busy making use of Federal and other subsidies to promote their inefficient, unreliable, and expensive “renewable” sources of electric power. America, however, is more and more dependent on reliable and inexpensive electric power for almost everything it does. One problem is that each proposed new “renewable” site has its own environmental problems such as killing birds or offensive sounds bombarding humans. They are also all very high cost when the costs of turning intermittent, unreliable electric power into useful, continuous, reliable energy are taken into account.

And now that it has been rigorously shown that higher levels of carbon dioxide (CO2) have no significant effect on global temperatures in the real world it is long past time to bring a halt to the use of taxpayer and ratepayer money to build additional wind and solar generating plants in addition to removing all regulations which have the effect of killing existing “non-renewable” power plants without a solid environmental justification. The case that the CIC has long made that CO2 has a significant effect on temperatures has always been shaky at best and has never been proved. Now we know that it is simply wrong. Yet the CIC is continuing to try to spend other people’s money–that of ratepayers and taxpayers–to build ever more wind and solar power plants. If this is allowed to continue, it will hobble America’s future just as it already has Germany’s and other Western European nations who have bought into the climate alarmist scam. Read more ☼

All-Renewable Energy Is a Prescription for Disaster

by Robert Bryce, Manhattan Institute

Last year, an all-star group of scientists thoroughly debunked the work of Mark Jacobson, the Stanford engineering professor who for years has been claiming the US can run solely on renewables.

In a paper last June in the Proceedings of the National Academy of Sciences, the scientists — including Ken Caldeira of the Carnegie Institution, Dan Kammen of the University of California, Berkeley, former EPA Science Advisory Board chairman Granger Morgan and Jane Long of Lawrence Livermore National Laboratory — concluded that Jacobson’s all-renewable scheme used “invalid modeling tools, contained modeling errors, and made implausible and inadequately supported assumptions.”

Those errors “render it unreliable as a guide about the likely cost, technical reliability, or feasibility of a 100-percent wind, solar and hydroelectric power system.”

The scientists also concluded that Jacobson’s all-renewable proposal would require covering about 500,000 square kilometers — a land area larger than the state of California — with nothing but wind turbines.

The idea of covering that much land with wind turbines is preposterous on its face, particularly given that rural residents from New York and numerous other states are already rejecting the encroachment of Big Wind.

The high cost of renewables can also be seen in California, which has mandated 50 percent of the state’s electricity be sourced from renewables by 2030. In February, Mark Nelson and Michael Shellenberger of the Berkeley-based think tank Environmental Progress reported California’s electricity rates rose at more than five times the rate of electricity prices in the rest of the US between 2011 and 2017. Californians now pay about 60 percent more for their electricity than residents of other states. Read more ☼

30-years later, James Hansen blasts renewables

The liberal news media lauded James Hansen, former head of NASA’s Goddard Institute, on the 30-year anniversary of his U.S. Senate testimony bringing global warming into the American political consciousness. Conveniently, however, most of the media failed to note Hansen’s criticisms of the environmental impacts of wind and solar power, while also failing to note his strong support for nuclear power. If not for Hansen taking matters into his own hands by writing multiple editorials on the topic, Hansen’s criticisms of wind and solar power may have never been known to anybody other than his close personal associates.

In a column this Wednesday in the Boston Globe, Hansen savaged the Paris climate accord and its predecessor the Kyoto Protocol as “wishful thinking” that allowed most countries to continue business-as-usual energy and environment policies. Sounds a little like President Trump, doesn’t it?

Hansen adds, “The notion that renewable energies and batteries alone will provide all needed energy is fantastical. It is also a grotesque idea, because of the staggering environmental pollution from mining and material disposal, if all energy was derived from renewables and batteries.” He follows that up by referring to the notion of an economy powered entirely by renewable energy a “fantasy.” (Source) ☼

A Trove Of New Research Documents The Folly Of Renewable Energy Promotion

By Kenneth Richard

The advocacy for widespread growth in renewable energy (especially wind, solar, and biomass) usage has increasingly become the clarion call of the anthropogenic global warming (AGW) movement. And yet more and more published research documents the adverse effects of relying on renewables. Over the course of the last year, at least 30 papers have been published in the peer-reviewed scientific literature detailing the fatuity of promoting renewable energy as a long-term “fix” for climate change mitigation.

UK Study Debunks Efficiency of Rooftop Solar Battery Backup Power

by Bonner R. Cohen

A new study from Great Britain refutes claims backup battery storage systems can cost-effectively offset the intermittency of residential rooftop solar power.

In assessing the cost-effectiveness of backup battery systems for rooftop solar panel arrays, the study concludes “such an installation is unlikely to provide any financial benefit.”

“Battery Wastage: Why Battery Storage for Rooftop Solar Doesn’t Pay,” was written by Capell Aris, a fellow at the Institute for Engineering and Technology in the UK, and published by the London-based Global Warming Policy Foundation. Read more Read full study ☼

If Renewables Are So Great for the Environment, Why Do They Keep Destroying It?

By Michael Shellenberger, Forbes

If solar and wind farms are needed to protect the natural environment, why do they so often destroy it?

Consider that:

New offshore wind turbines in Germany could “lead to the extinction of individual species” including the rare, intelligent, and highly-threatened harbor porpoise, according to Friends of the Earth-Germany (BUND).

Migratory bat populations, including the hoary bat, could could go extinct, say scientists, if the expansion of wind energy in North America continues.

A single California solar farm, Ivanpah, required the killing of hundreds of desert tortoises, the state’s threatened reptile, and annually kills six thousand birds by lighting them on fire. Wind turbines on California’s Altamont Pass killed an estimated 4,700 bird kills annually including Golden Eagles. “Some lose their wings,” says the Audubon Society, “others are decapitated, and still others are cut in half.” Read more ☼

A Crisis In Electric Power Everyone Is Ignoring

by Stephen Moore

Is anyone paying attention to the crisis that is going on in our electric power markets?

Over the past six months, at least four major nuclear power plants have been slated for shutdown, including the last one in operation in California. Meanwhile, dozens of coal plants have been shuttered as well — despite low prices and cleaner coal. Some of our major coal companies may go into bankruptcy.

But this is not a free-market story of Schumpeterian creative destruction. If it were, then wind and solar power would have been shut down years ago. They can’t possibly compete on a level playing field with $3 natural gas.

In most markets, solar and wind power survive purely because the states mandate that as much as 30% of residential and commercial power come from these sources. The utilities have to buy it regardless of price. The California state legislature just mandated solar panels for homes built after 2020 (an added construction cost of about $10,000 per home).

Over $100 billion in subsidies have been doled out to big wind and big solar over the last decade. Even with the avalanche of taxpayer subsidies and bailout funds, many of these companies, such as Solyndra (which received $500 million in handouts), failed.

These industries are not anywhere close to self-sufficiency. Without a continuation of a multibillion-dollar tax credit, the wind turbines would stop turning. Read more ☼

Don’t recycle plastic – burn it or bury it

Plastic in the oceans has been deemed an environmental problem and a danger to wildlife. Where does this plastic come from? According to a new report from the Global Warming Policy Foundation, much of the plastic comes from “leakage” from recycling operations. Some of that “leakage” is deliberate dumping in oceans and rivers by shippers in order to avoid fees.

The report: Save the Oceans – stop recycling plastic may be read in full here:

https://www.thegwpf.org/content/uploads/2018/06/Save-the-oceans.pdf

The report is just ten pages, but it cites 50 scientific studies and articles.

Here is the executive summary:

A marine plastic litter crisis has been declared and the mass media around the world has given their front pages over to the story for a while now. The European Union – among other actors – has declared a war against marine litter. Annually over 10 million metric tons (Mt) of plastic litter end up in oceans, harming wildlife. The International Solid Waste Association (ISWA) – the most competent specialist organization in the field – has summarized the origins of the marine litter crisis:

75% of land based marine litter in low to upper-middle income economies comes from litter and uncollected waste, while the remaining 25% of the land-based sources is plastic which leaks from within the waste management system.

In other words, the ISWA report shows that 25% of the leakage is attributable to the waste management option preferred by green ideologues; meanwhile, waste incineration can prevent any leakage of plastic if municipal solid waste (MSW) is incinerated along with sewage sludge. Despite this, incineration is vehemently opposed by green ideologues and also by the EU, which chooses to believe in the mirage of a circular economy.

The vast majority of the marine litter problem is attributable to poor waste collection and other sanitary practices in Asian, and to a lesser extent African, towns and cities in coastal areas and along rivers. The problem is particularly acute in China. The neglect of urban sanitary policy – the backbone of development agendas until that time – started when the ‘mother of sustainability’, Norway’s Prime Minister Gro Harlem Brundtland, personally refused to have it be part of her World Commission’s work program and ultimately its 1987 report, which famously led to the adoption of ‘sustainable development’ goals by the UN General Assembly.

This report describes the absurdities, inefficiencies, double or even triple waste management structures and horrible consequences of the EU’s erratic green waste policy, its fact-free claim that its waste policy helps to implement the Paris climate agreement, and its dumping of 3 Mt of plastic in China each year, with horrific consequences for the marine environment and health.

The EU has now started to sideline – in the name of circular economy – the highly successful waste incineration policy implemented in seven EU member states – Austria, Belgium, Denmark, Finland, Germany, the Netherlands and Sweden – which all have major waste incineration capacity and now landfill less than 3% of their MSW.

The study notes the best thing to do is bury plastic in landfills or burn it. However, these methods don’t fit into the environmentalist’s scheme of sustainable development. Burning plastic along with other material has very few undesirable emissions. The resulting ash can be sent to landfills or used for applications such as road-building materials.

The study’s author, Mikko Paunio, opines: “that ideologically motivated environmentalists in the 1980s and their dreams of recycling and a ‘circular economy’ are the ultimate cause of the marine waste problem, because they have discouraged development of municipal waste schemes in Asia and Africa, and because they have encouraged developed nations to use management schemes that make it hard or expensive to deal with waste and therefore tend to ‘leak’ to the environment, sometimes catastrophically so.”

Recycling plastic poses some problems. First much plastic has to be washed which uses large amounts of water. Plastic also has to be sorted from other waste and by type of plastic because recycling processes are different for different types of plastic.

Save time, water, energy, and expense by burning or burying plastic. Don’t recycle it.

The plastics in the ocean problem has spawned some dumb regulations. For instance, silly in Seattle:

http://www.foxnews.com/politics/2018/07/02/seattle-bans-plastic-straws-utensils-becoming-first-major-us-city-to-do-so.html

The solution is to have more-careful waste collection and management.

Renewable energy mandates and politics versus science

Competing renewable energy mandate legislation will appear on the Arizona this fall. You can read about them in two Arizona Daily Star stories:

Arizona utility APS crafts renewable-energy initiative with escape clause

Arizona Senate puts utility-written renewable energy plan on ballot

Neither addresses the real issue: electricity produced from utility-scale solar and wind is unreliable, expensive, plays havoc with electrical grid stability, and is not as green as advertized. Rather than play with tricky fixes, the Arizona legislature should repeal the Arizona Corporation Commission’s renewable energy mandate and forbid the ACC from mandating how electricity is generated. I can find no place in the Arizona Constitution nor in the Arizona Revised Statutes that gives the ACC authority to impose such mandates.

For background of ACC action, read a report from the Goldwater Institute: “Rediscovering the ACC’s Roots: Returning to the Original Purpose of the Arizona Corporation Commission” (link)

Here is the executive summary of the 26-page report:

The Arizona Corporation Commission was established through the state constitution to regulate corporations, public utilities, securities, and other investments. But in an unprecedented move, the Arizona Corporation Commission sought to single-handedly determine alternative energy policy in Arizona with a bold and unconstitutional energy mandate in 2006.1 This mandate forced energy producers to embrace state-favored alternatives instead of deciding for themselves which options are most attractive in Arizona.

Arizonans now face the real threat that the Arizona Corporation Commission will continue to seize power meant to be held by the state’s legislative branch. Important decisions about energy policy, corporate governance, and other areas have been removed from the legislative process which, for all its faults, offers more transparency, citizen input, and accountability than the opaque and bureaucratic proceedings of the Arizona Corporation Commission.

The framers of the Arizona Constitution had serious concerns about the Commission’s potential to abuse its authority. Records of the state constitutional debate show the constitution’s authors intentionally limited the Commission’s powers to prevent interference with internal business decisions. The framers’ fears have been borne out.

The Commission’s attempt to act as the state’s de facto energy czar clearly oversteps its original role.

Arizona courts should re-establish a proper balance between the Commission and legislative power. Courts in other states with similar utility regulatory commissions already have concluded such agencies don’t have constitutional authority to mandate statewide policy. The Legislature also can reassert its authority by ordering an audit of the Commission that would recommend ways to streamline the agency and to restore it to its proper role. Finally, the state constitution could be amended to transfer necessary functions to other agencies and decommission the ACC to stop its policymaking power grabs, which Arizona’s founders specifically aimed to prevent.

See these articles for more detail on the consequences of the ACC mandate:

Six reasons Arizona should repeal its renewable energy standards mandate

The economic impact of Arizona’s renewable energy mandate

The high cost of electricity from wind and solar generation

The more installed solar and wind capacity per capita a country has, the higher the price people pay for electricity.

Political correctness versus science:

The alleged rationale for these mandates is that we must reduce carbon dioxide emissions to forestall dread global warming. But, there is no physical evidence that emissions from fossil fuels play a significant role in driving global temperature. See these ADI posts for more detail:

A Simple Question for Climate Alarmists

“What physical evidence supports the contention that carbon dioxide emissions from burning fossil fuels are the principal cause of global warming since 1970?” I posed that question to five “climate scientist” professors at the University of Arizona who claim that our carbon dioxide emissions are the principal cause of dangerous global warming. Yet, none could cite any supporting physical evidence.

Evidence that CO2 emissions do not intensify the greenhouse effect

The “greenhouse” hypothesis of global warming makes four major predictions of what we should see if the “greenhouse effect” is intensified by adding carbon dioxide to the atmosphere. All four predictions are shown by physical evidence to be wrong.

What keeps Earth warm – the greenhouse effect or something else?

An alternative hypothesis with observable evidence.

Failure of climate models shows that carbon dioxide does not drive global temperature

Results from climate models based on the assumption that carbon dioxide controls global temperature diverge widely from reality.

Russian collusion with environmentalists to disrupt American energy production

It seems that there is indeed Russian collusion, collusion with environmental groups to harm American energy production. This has been going on for years.

Environmentalists have campaigned for the following:

1) US nuclear energy facilities to close down

2) US fossil fuel reserves to stay in the ground (onshore and offshore)

3) the costs of fossil fuels to go up (e.g. with a carbon tax)

4) a high percentage of the US electric grid to be based on unreliable sources? (wind and solar)

5) the US to waste trillions of dollars on unreliable electricity

All of this plays into Russian hands as they battle to maintain their European markets.

 

See a Congressional Report about this collusion:

Mar 1, 2018,WASHINGTON – U.S. House Science, Space, and Technology Committee Chairman Lamar Smith (R-Texas) released a staff report uncovering Russia’s extensive efforts to influence U.S. energy markets through divisive and inflammatory posts on social media platforms. The report details Russia’s motives in interfering with U.S. energy markets and influencing domestic energy policy and its manipulation of Americans via social media propaganda. The report includes examples of Russian-propagated social media posts.

According to the report: “Russia has a significant interest in disrupting U.S. energy markets and influencing domestic energy policy. American energy is booming. America’s emergence as a global energy exporter presents a significant threat to Russian energy interests. Such competition reduces the revenue and influence generated by Russian energy exports. This adversely affects the Kremlin’s ability to leverage Eastern Europe’s reliance on their energy and their ability to carry out their geopolitical agenda. The surge of American energy into the global marketplace heightens the Kremlin’s desire to eliminate or mitigate the American energy threat and to do so by influencing social media users, American voters, and public officials.”

Consider these stories:

Environmental group may have to register as foreign agents

Reported by Washington Examiner, 01/15/18 Link to story

“U.S. environmental activists who are working to halt the production and use of fossil fuels could be required to register as foreign agents if Congress gets serious about enforcing an existing law.” The Foreign Agents Registration Act, passed in 1938, calls for individuals and organizations to provide full disclosure when they are working to advance the public policy interests of a foreign government.

Democrats dig for Russian connection and uncover environmentalists.

Reported by The Hill, 10/26/17. Link to story

“Democrats and the media have been on a year-long deep dig into Russian involvement into U.S. elections. But when you dig a hole you sometimes run across things you wish had remained buried — like the dirt pointing to Russian ties to the U.S. environmental movement.

Russia secretly working with environmentalists to oppose fracking.

Reported by The Guardian, 19/06/14. Link to story

Anders Fogh Rasmussen, secretary-general of the North Atlantic Treaty Organization (Nato) said: “I have met allies who can report that Russia, as part of their sophisticated information and disinformation operations, engaged actively with so-called non-governmental organizations – environmental organizations working against shale gas – to maintain European dependence on imported Russian gas.”

The high cost of electricity from wind and solar generation

Written by Jonathan DuHamel

Some European countries, particularly Germany and Denmark, have invested heavily in electricity generation from solar and wind sources with the result that the cost of electricity has increased substantially. The alleged rational for using “green” energy is that it would reduce carbon dioxide emissions and save us from dread global warming. The reality is that carbon dioxide emissions have not been reduced and real world evidence shows that carbon dioxide emissions have almost no influence on global temperature. (See my Wryheat post: Evidence that CO2 emissions do not intensify the greenhouse effect).

Here is what is happening in Europe. The more installed solar and wind capacity per capita a country has, the higher the price people pay for electricity. In the graph below the vertical scale is Euro cents per kilowatt-hour, the horizontal scale is the installed capacity of renewables (solar and wind) per capita. (For reference, the U.S. average residential cost is 12 cents/kwh which is about 9.6 euro cents/kwh, lower than all European countries on the graph.)

 

Pierre L. Gosselin, a graduate of the University of Arizona who resides in Germany, writes: “Despite the rapidly growing green energy capacity being installed, the effort to reduce CO2 has failed, and what’s left is an unpredictable power grid that often produces energy when it is not needed (waste energy) and thus costing Germans hundreds of millions annually. The Green Party claims that wind energy is “the most inexpensive” on the market, but “If that is really true, then why do they need subsidies? Why are we paying 25 billion euros annually for their feed-in?” An array of expert panels have determined that wind energy is not leading to more climate protection, but rather is only making electricity outrageously expensive.” (Source)

Australians are experiencing the same thing. The last 65 years of Australian electricity prices — indexed and adjusted for inflation show that during the coal boom, Australian electricity prices declined decade after decade. As renewables and national energy bureaucracies grew, so did the price of electricity. (Source) See graph at source.

Peter Rez (Professor at Arizona State University) explains Why solar and wind won’t make much difference to carbon dioxide emissions (Oxford University Press)

“In many circles there is a comforting belief that renewables such as solar and wind can replace fossil fuel electrical generation and leave us free to live as we do without carbon dioxide emissions. Fundamental physics and engineering considerations show that this is not so.”

“Power needs fluctuate with time of the day and, to a lesser extent, day of the week. In most places, peaks occur in the evening when people come home, start cooking, and turn on lights and entertainment systems. In Arizona in summer, the peaks are even more extreme due to the air conditioners all cutting in. There are also morning peaks, as people get up and turn on lights and hair dryers. Commercial and industrial use generally doesn’t change much throughout the day. The electrical utilities call this a baseload.”

“Solar and wind present two problems. One is low power density; massive areas have to be devoted to power generation. The other, more serious problem is intermittency. If we only wanted to run electrical appliances when the wind is blowing or the sun is shining, fine, but don’t expect to use solar to turn on your light at night! So solar and wind cannot manage on their own; it’s always solar or wind AND something else.” Read more

All of this has implications for Arizona energy policy.

In 2006, the Arizona Corporation Commission (ACC) imposed the Renewable Energy Standard and Tariff (REST) on non-government-owned electric utilities. REST requires that electric utilities generate an ever increasing amount of electricity from renewable sources such as wind and solar. The original mandated goal was to reach a total of 15 percent renewable generation by the year 2025.

Now ACC commissioner Andy Tobin is campaigning for what he calls an “Energy Modernization Plan.” (See ADI article “Tobin Appears To Overstep With Energy Modernization Plan”)  Read full plan at:   http://www.azcc.gov/commissioners/atobin/letters/energyplan.asp 

From the plan: “The singular unifying goal is to have Arizona’s economy powered by clean energy sources that make up at least 80 percent of the state’s electricity generating portfolio, by 2050, with the ultimate goal being 100 percent.

The high cost of electricity from wind and solar generation refers not only to the price of electricity, but also to the cost to the environment and health of humans and other animals.

Several years ago I wrote a Wryheat post: “Petition to Arizona Legislature – Dump Renewable Energy Mandates” which lists six reasons why the Arizona legislature should get rid of this mandate. Besides the cost and grid instability, solar and wind generation are not as “green” as advertised.

For example, many PV solar panels rely on polysilicon being manufactured in large quantities and at high quality. A byproduct of polysilicon production is silicon tetrachloride, a highly toxic substance that poses a major environmental hazard. Wherever silicon tetrachloride is dumped, the land becomes totally infertile. A major environmental cost of photovoltaic solar energy is toxic chemical pollution (arsenic, gallium, and cadmium) and energy consumption associated with the large-scale manufacture of photovoltaic panels.

Concentrating solar plants such as the Ivanpah generating station, in the Mohave Desert southwest of Las Vegas, uses 173,500 heliostats each with two mirrors to focus sunlight on a tower where water is converted to steam to generate electricity. This method is called “solar-flux” and it generates very high temperatures. Birds experience traumatic impact with the mirrors, but the larger danger is getting singed by the heat flux which is up to 800 degrees F. (See my post: Avian Mortality from Solar Farms)

Wind turbines chop up millions of birds and bats every year. (See: Wind Turbines Versus Wildlife) Wind turbines also cause health problems in humans and other animals due to their low-frequency noise and the “flicker” of the turbines themselves. (See: Health Hazards of Wind Turbines)

I can find no place in the Arizona State Constitution nor the Arizona Revised Statutes that gives the ACC explicit authority to dictate the methods by which utilities must generate electricity. I recommend that the Arizona legislature repeal the Renewable Energy Standard and Tariff and forbid the ACC from dictating how electricity must be produced. Instead, let the free market decide.

Generating more electricity from solar and wind is just a very expensive exercise in political correctness that will have little impact on carbon dioxide emissions, but a big impact on your wallet.
