The sun and the wind are free, but converting them to reliable electricity is expensive, if not impossible.

In an effort to get America off of fossil fuels, “free” solar and wind energy is often touted as the solution. However, in reality, the so-called free energy has high costs and does little to minimize fossil-fuel use or cut greenhouse gases.

Because solar-and-wind energy are not available 24/7—also frequently referenced as not “dispatchable”—incorporating them into the electricity portfolio requires back-up power to be available on demand. When the sun doesn’t shine or the wind doesn’t blow, we still expect to have heating or air conditioning, cook our dinners, charge our phones, and use our computers. This requires fossil fuels—typically natural gas “peaking plants,” but depending on what is available, it may be a coal-fueled power plant that is forced to operate inefficiently, releasing more CO2 than it would if allowed to operate as intended.

Think of it this way.

If you want to cook a hamburger, and you have a charcoal grill, you go outside about 30 minutes before you plan to cook. You mound up the charcoal, sprinkle it with lighter fluid, and toss on a match. When the coals are white on the edges, you know they are ready. You put your burger on the grill and cook it for five to eight minutes. Once you remove the burger, the coals are still hot for hours. Ultimately, they burn down to ashes and are cold enough that you can throw them into your plastic trash can, or into the forest. To restart it later in the same day is not efficient.

By comparison, if you are going to cook that same hamburger over natural gas, or propane, you go out five minutes before you plan to grill to heat up the elements. You cook your burger, and you turn it off. No coals, no cool down needed.

Power plants function in a similar fashion.

A coal-fueled power plant cannot easily be turned on and off. It works most efficiently—i.e., cleanly—when it burns continuously. Like the grill, you can add more coal throughout the process to keep the temperature up, which creates the steam that generates electricity.

But with a natural-gas-fueled power plant you can easily turn it on and off. So when the wind suddenly stops blowing—with no warning, the gas plant can quickly ramp up to generate the needed power.

As Germany, with the highest implementation of renewable energy of any country, found out, to maintain grid stability, it needs the coal- and natural-gas-fueled power plants. As a result of its policies that favor renewables, such as solar and wind, Germany has had to subsidize its fossil-fueled power plants to keep them open.

So, by adding solar and wind power, to the energy mix, we actually increase costs by paying for redundant power supplies—which ultimately, through rate increases, hurts the less fortunate who also have to cover the costs of the renewables.

In the cold weather of Albuquerque’s winter, I received a call from an “unemployed single mother living in an 800 square-foot apartment.” When I answered the phone, she dumped on me. She was angry. Her life circumstances meant she didn’t turn on her heat because she couldn’t afford it. After stating her position, she ranted at me: “I just opened up my utility bill. I see that I am paying $1.63 a month for renewable energy.” She continued: “I don’t give a f#*! about renewable energy! Why do I have to pay for it?”

I tried to steer her attention away from the utility company and toward the legislature that nearly a decade ago passed the Renewable Portfolio Standard, which requires increasing amounts of more expensive renewable energy. As a result, her rates went up, and she had no say in the matter—except that she may have voted for the legislators who approved the policy.

Recently, in Florida, the state NAACP chapter had an op-ed published that, essentially, said the same thing: renewable energy costs those who can least afford it.

It is not that renewable energy is bad. I have friends who live off the grid. They are cattle ranchers, who live in New Mexico’s Gila Forest. Were it not for their solar panels, they’d have no lights, no computers, no direct contact with the rest of the world. For them, solar panels on the roof—with a back-up system of car batteries—are their salvation. At a cost that worked for them, they were able to purchase used solar panels that someone else had discarded. They are grateful for their solar panels, but they have little option—and they know that, they accept it.

Without thinking of what works well in each situation, government has tried to apply a one-size-fits-all solution. Based on a phony narrative of energy shortages and global warming, err, climate change, renewables have been sold as the panacea. While they may be the right choice in a few cases, such as my cattle ranching friends, or even in the oil fields—which are one of the single biggest industrial users of solar power, many individual locales may be better served by coal, or natural gas, even nuclear, than by renewable power. But the mandates, or the EPA, have not taken that into consideration.

In New Mexico, there are two coal-fueled power plants situated, virtually, at the mouth of the coal mine. The coal is extracted and sent via conveyor belt straight to the power plants that generate most of New Mexico’s power and provide enough excess to sell to neighboring Arizona and California. But EPA regulations require that these plants, with years of useful service left, be shut down. Some of the units will be converted to natural gas—something the region also has in abundance. However, the natural gas has pipelines that can take it to the world markets; it is not stranded the in the San Juan Basin.

In contrast, the coal cannot conveniently leave the area—there is no rail to transport it. Looking at the specifics of the basin, it makes sense to continue to generate electricity from coal and allow the natural gas to benefit markets (perhaps even our allies) without other resources—but the EPA and its environmental advocates will hear nothing of it. Their ideology drives the policy whether it makes economic, or practical, sense or not.
