Radical efforts in moving away from fossil fuels is very risky

May 23, 2023

There has been a lot of talk lately about gas stoves, and the possibility of them being banned.

A story from the January edition of Popular Mechanics magazine quoted Richard Trumpka, Jr., who is a commissioner on the U.S. Consumer Product and Safety Commission, as saying that due to concerns about health conditions such as respiratory illness, cancer, and childhood asthma, the federal government has a ban “on the table” to prohibit gas stoves in homes. “This is a hidden hazard. Products that can’t be made safe can be banned,” Trumpka said.

Trying to put concerns of a ban to rest, Energy Secretary Jennifer Granholm assured members of the House Energy and Commerce Committee that the Biden administration does not seek to ban gas stoves.

“I will say that the Department of Energy is not banning any gas stoves, that we are doing our duty to make sure that appliances are more energy efficient as we are required to do under the Energy Policy Conservation Act of 1975,” she told the Committee. “Nobody’s taking my gas stove, nobody will take your gas stove. But in the future, gas stoves that are high-end, which is all that we looked at, can be more efficient.”

Also, at about the same time came news that in order to combat health and climate risks, the state of New York has banned the use of natural gas for cooking and heating in most new residential buildings. And, the Energy Department, “is proposing new efficiency rules for gas stoves that only about half of current models on the market would likely comply with,” The Washington Times reported.

Also, a number of cities in California, Massachusetts and Washington are working to end using natural gas in homes and other buildings.

Burning things like coal, oil, natural gas, kerosene and wood is not good for the environment, as we all know. Burning natural gas in stoves emits nitrogen dioxide (NO2) when it is burned at high temperatures in the presence of nitrogen in the atmosphere. This can irritate human airways and can cause or exacerbate respiratory problems. 

Smoking too much, drinking too much alcohol, and lots of other things are also harmful, but they are not banned, and in some cases not even heavily regulated. The key to this is knowing how harmful to people young and old is it to burn natural gas in homes. 

An article on the Scientific American website notes: “The American Gas Association (AGA), a natural gas industry group, issued a statement pushing back against the December 2022 study that linked gas cooking with asthma. The statement claimed the study authors did not conduct measurements of real-life appliance use and ignored some of the scientific literature on this topic. The AGA cited a separate study that found no evidence of a link between cooking with gas and asthma symptoms of diagnosis.”

While it is true that the AGA has a vested interest in opposing the idea that burning natural gas can potentially cause health issues, the Biden administration also has a vested interest: its mission to kill all fossil fuel use. But since American natural gas is the cleanest on Earth, is our use of it really that harmful to the environment?

And given the way China and India continue to increase their use of fossil fuels, and considering our efforts to make them cleaner, is our using them really a serious problem? Should the U.S. work at a pace to eliminate fossil fuels so fast that it will negatively affect its people, particularly when other nations increase their damage to the environment more than the U.S. reduces it?

Virginian Mark Christie serves on the Federal Energy Regulatory Commission (FERC). He wants people to understand the trouble the nation is headed toward with its current path on energy.

He joined the FERC panel in January 2021, prior to which he was a member and former chairman of the State Corporation Commission, Virginia’s energy regulator, for 17 years.

Appearing before a U.S. Senate committee earlier this month, Christie said that “The United States is heading for a very catastrophic situation in terms of reliability. The arithmetic doesn’t work,” he said. “This problem is coming. It’s coming quickly. The red lights are flashing.”

Christie bases his warning on problems in the recent past, such as the deadly energy catastrophe Texas experienced two years ago, and the problems in the eastern part of the country last year as Christmas approached.

Three other FERC commissioners joined him in the message to the Senate, and Virginia’s Governor Glenn Youngkin and Dominion Energy Virginia have expressed their concerns, too.

The message they are sending is that eliminating most or all fossil-fuel-produced electricity too rapidly, and replacing it only with wind and solar, is a recipe for failure. 

Wind and solar are nowhere near the point where they can carry the load alone. Solar panels and wind turbines produce nothing most of the time. Fossil fuels work all of the time.

Someday in the future wind and solar will have developed sufficiently through natural development to replace fossil fuels. We don’t need this radical effort to force it on the nation.

Renewable energy to replace fossil fuels? Will that be much better?

We have been told for years about the damage to the environment of burning fossil fuels, and the marvelous benefits of renewable energy sources like wind and solar. Steps have been taken and more are being put forth to reduce the amount of CO2 we produce, on concerns of “climate change.” America, incidentally, has led most, if not all, of the world in reducing CO2 in recent years.

And, regardless of whether humankind is really harming the environment to a serious level, we can agree that wind and solar energy are far less polluting when they are in use than machines that burn oil, gasoline, diesel fuel and natural gas.

But when you look at what happens in the process of turning these sources into useful products, and what happens to them after their useful life is over, a very different story emerges.

The details of these processes and products were explained in a Prager University video featuring Mark Mills, Senior Fellow at the Manhattan Institute, who discussed the environmental costs of using these energy sources.

First, windmills and solar panels, and the batteries to store the electricity they produce, are made from non-recyclable materials, Mills said. And after some 20 years since the wind and solar energy technologies were born, and after billions of dollars of subsidies, those two sources provide less than three percent of the nation’s power. 

Mills explained that the maximum rate that wind can be turned into electrons is about 60 percent, and the maximum for sunlight is about 33 percent. As of now, we can convert 45 percent of blowing wind and 26 percent of shining sun. Technology is now able to get a little more than half the possible electrons from the wind and the sun. That will likely increase as technology advances.

Since the wind does not blow and the sun does not shine all the time, excess electricity must be stored in batteries. Mills put that into perspective: The world’s largest battery plant, created by Tesla in Nevada for its electric vehicles, would need 500 years to make enough of the batteries it makes today to store enough electricity for just one day of current U.S. demand.

Of course, more battery plants will gradually be built, and perhaps the capacity and efficiency of batteries will also increase. But this presents a tremendous challenge if the U.S. is to end using fossil fuels, as we are told we must, in favor of renewables.

The processes to enable wind and solar energy to produce electricity, he said, are quite expensive, in environmental terms.

One electric car battery weighs half a ton. But to acquire the materials to produce it, 250 tons of earth from somewhere must be mined and processed.

One 75 mega-watt wind farm powers 75,000 homes, and requires 30,000 tons of iron ore, 50,000 tons of concrete, and 900 tons of non-recyclable plastic. And a 75 mega-watt solar farm requires 150 percent more materials — concrete, steel and glass — than a wind farm.

The rare earth and other metals needed — lithium, cobalt, copper, iridium and dysprosium — will require a massive increase in mining activity: from 200 to 2,000 percent of the mining now occurring.  Rare earth materials are mostly not available in the U.S., but must be acquired from other countries Some of them, like China, are hostile to us. In 2019, China was responsible for 80 percent of rare-earth materials.

And, the equipment and processes used in acquiring and refining the materials, and constructing and installing the windmills, solar panels and batteries are powered by fossil fuels.

After about 20 years of production, these windmills and solar panels will have exhausted themselves, leaving millions of tons of non-recyclable waste behind that must be put somewhere.

Mills also said that the plastic waste from these sources will total more than twice the amount of all existing plastic waste.

Using the sun and the wind to our benefit makes perfect sense. The more seasoned readers may remember fondly your grandmother or mother hanging freshly washed clothes on the line in the back yard to dry in the sun and breeze. And then electric dryers came along.

The idea that transitioning from burning fossil fuels to wind and solar energy to produce electricity will be cleaner is false. We will trade polluting the air for producing tons of solid waste.

Too much of anything can be harmful: too much vitamin C, too much water, too much sun, too much oxygen, and too much CO2. But the environmental cost to replace fossil fuels with wind and solar power might be as expensive, or more expensive, than the cost of burning fossil fuels, in terms of the waste that is produced.

Geologist and earth scientist Professor Ian Plimer, who is called a “climate change denier” by some, said our “climate is cyclical,” and that Earth is heading to an ice age.

“We are getting towards the end of the warm period, the peak of the warmth was about 5,000 years ago and we are heading for the next inevitable ice age,” he told Sky News.

If so, someday we may want and need more CO2, not less.
