I've learned that some utilities were surprised when they did their last 5-year energy plan to learn that renewable energy has become cheaper than fossil fuel and that they have accelerated the closing of their coal-fired power plants. For example, NIPSCO. I found that hard to believe.

But this article explains that if you use the "levelized cost," the utility scale solar production of electricity is already competitive with fully depreciated fossil and nuclear fuel power plants. It defines "levelized cost" as what I think of as life-cycle cost. "The levelized cost of energy analysis takes into account the capital costs, fuel costs, operations and maintenance costs, debt and equity costs, and plant utilization rates for each type of electric power generation." But that comparison includes U.S. government subsidies. I could not find figures for the cost if subsidies are excluded.

I've learned that having zero fuel costs for sunlight and wind is a serious economic advantage. However, the article does mention that a lot more money is going to have to be put into the grid to compensate for the unreliable nature of green power. That is, what do you do when the sun doesn't shine or the wind doesn't blow? An implication of zero fuel costs is that billing is going to have to change. Instead of paying for the electricity you use, you will need to subscribe for the capability of getting electricity. That is, you pay a monthly fee for a service level of a max usage rate and an availability agreement. [reason]
Update: I generalized these notes to green energy.
I've witnessed a similar evolution of billing for phone calls. When I was a kid in the 1960s, I remember my Mom thinking about what all she wanted to say before she dialed a long distance call because she wanted to be able to say everything on her mind in three minutes. For each minute past the initial three minutes, she would have to pay more money. When I started work in the Chicagoland area in 1973, we had to pay units for calls outside of our "local area." A "local area" covered the nearby suburbs. I don't know how big a "local area" was in Chicago. But I don't think it was the whole city. I remember a unit cost about five cents. By the turn of the century, fiber optics had made long distance so cheap that the phone bill included unlimited free long distance calls. In fact, work started providing a regular phone number, in addition to an 800 number, for our conference calls because so many employees had free long distance calls in their billing plan.
Cell phone calls is another example of a service that went from per-minute billing to unlimited minutes. For cell phones, you paid for "air time" so the per-minute charge included the time it took to make the call as well as "talking time." That is, you paid for calls that were not answered. Then cell phone calls became free, but you had to pay for text messages. Then text messages became free, but you had to pay for data. Now my calls, text and data is unlimited, but I probably pay a rather hefty monthly bill. In fact, I pay more for my cell phone service than I do for electricity. Now that I'm thinking about it, my cable bill is also more than my electric bill.
I have not been able to find a pie chart showing which countries are manufacturing the solar panels that the utilities are using to build their solar farms. It would be nice if some companies would build solar panel factories in Western Virginia and and other coal producing states to provide replacement jobs. My first thought was to build wind turbine components in the coal producing states, but putting those plants closer to the "windy states" (Great Plaines and Midwest) makes sense because they are a lot harder to transport.
By coincidence, the Chicago Tribune has an article in their Nov 4, 2020, edition on green energy development in Texas. While the oil and gas jobs are plummeting, the advanced energy jobs are growing "at twice the rate of the Texas labor market --- at least before the pandemic." (The article uses the term "advanced energy," and it includes storage batteries as well as the renewables of solar and wind.) The generation of wind power has increased from 6% in 2009 to 20% in 2019. Specifically, wind has increased from 9 gigawatts to almost 24 GW. I'd guess that 24 GW is equivalent to roughly 20 modern coal-fired plants. And Texas has been able to attract corporations that want to use renewable power. "Last year, corporations in the U.S. bought 23 gigawatts of electricity through power purchase agreements. That shattered the previous year's record, with Texas being the primary beneficiary, according to the 2020 Sustainable Energy in America Factbook. 'Companies are flocking to the Texas power market,' said the book, which is researched and produced by the BloombergNEF. Texas generators landed 40% of the purchase contracts last year."

The pendulum seems to be swinging back and forth. But it seems to be a matter of when, not if, they will be carbon free. "Xcel said it is on a path of reducing carbon by 80% by 2030, and has "a vision to provide our customers across our entire service territory with 100% carbon free electricity by 2050." The utility is finalizing a clean energy plan it will file with the PUC by March." [UtilityDive]

US agriculture is very energy dependent. Not only does it need a lot of diesel fuel, it needs fertilizer. But Air Protein (source) would consume carbon dioxide rather than generate it. Basically, NASA found a class of bacteria (hydrogenotrophs) that poop amino acids. It is made in fermentation vessels similar to yogurt or beer. The product is about 80% protein compared to 40% in typical soy protein flour.

| safe_image for Natural Gas, America’s No. 1 Power Source, Already Has a New Challenger: Batteries "A megawatt of electricity can power about 200 homes, according to the Electric Reliability Council of Texas, which operates the state’s power grid. Some other estimates peg this number higher." [Gas forced coal-fired plants to become stranded assets. Now it is looking like renewable energy and batteries could turn gas-fired plants into stranded assets. Power companies are looking at building new gas-fired plants with a 25-year lifespan instead of the traditional 40-year lifespan. Coal-fired plants were near the end of their lifespan anyhow. That is not true for the 60 GW of gas plants built in the US since 2014.] "Already, the cost of discharging a 100-megawatt battery with a two-hour power supply is roughly on par with the cost of generating electricity from the special power plants that operate during peak hours. Such batteries can discharge for as little as $140 a megawatt-hour, while the lowest-cost 'peaker' plants—which fire up on demand when supplies are scarce—generate at $151 a megawatt-hour, according to investment bank Lazard. Solar farms paired with batteries, meanwhile, are becoming competitive with gas plants that run all the time. Those types of projects can produce power for as little as $81 a megawatt-hour, according to Lazard, while the priciest of gas plants average $73 a megawatt-hour. Major battery projects under way in New York and California are driven in part by state mandates to slash carbon emissions, not just improving battery economics. Even in Texas, a state with a fiercely competitive power market and no emissions mandates, scarcely any gas plants are under construction, while solar farms and batteries are growing fast. Companies are considering nearly 88,900 megawatts of solar, 23,860 megawatts of wind and 30,300 megawatts of battery storage capacity in the state, according to the Electric Reliability Council of Texas. By comparison, only 7,900 megawatts of new gas-fired capacity is under consideration.... Most current storage batteries can discharge for four hours at most before needing to recharge. Once complete, the batteries at Moss Landing will supply 400 megawatts of power for four hours." |
