Wind Power Eclipses Both Coal, Nuclear In the US (npr.org) 87
An anonymous reader quotes a report from NPR: On March 29, wind turbines produced more electricity than coal and nuclear, the U.S. Energy Information Administration, an agency that collects energy statistics for the government, says. In the past, wind-powered electricity has gone beyond coal and nuclear on separate days, but this was the first time wind surpassed both on the same day. Natural gas is still the largest source of electricity generation in the country.
The EIA notes that in the spring and fall months, nuclear and coal generators reduce their output because demand tends to be lower, which could contribute to why wind turbines produced more electricity that day. But wind taking the No. 2 spot may be short-lived. The agency says electricity generation from wind on a monthly basis has been lower than natural gas, coal and nuclear generation. According to EIA projections, wind is not expected to surpass any other method in any month of 2022 or 2023.

Wind is the most effective alternative. Opposing it means supporting the continued consumption of coal and gas.

The power comes from spreading out the wind stream an reducing its momentum. But the momentum comes from the air moving over the blade surfaces. Take too much momentum out and you reduce the amount of air, and momentum to harvest, that goes through the blades, and you get LESS power as you take more. Take it all and you get no power at all.

Wind Power Eclipses Both Coal, Nuclear In the US

Coal shortages are a large factor (Score:4, Interesting)
Anybody familiar with the power industry knows that right now power prices are extremely high, pushing $100/MWh in some markets. In what is traditionally a shoulder month. Why? Shortages. There are severe logistical issues in moving coal right now, combined with extremely high gas prices and a grid that simply isn't very reliable due to its wind resources in particular. MISO, in arguably the "easiest" part of the year to supply power, is running a negative reserve margin. They don't actually have enough reserve capacity to ensure reliability, and they know it.
But long story short, coal generation is running at a fraction of the capacity it *could* be running at, not for economic reasons but simply because there's extreme issues in physically getting the fuel to the plants. PJM is currently requiring coal inventory management updates to ensure smaller generators don't burn their whole fuel stock to make tons of money now, and cause blackouts in August. By the numbers most coal units would be running literally flat out 24/7 based on economics... which is insane. Wholesale power prices are up 200% year over year. Those coal plants aren't even designed to be able to replenish fuel that quickly, the old grid management techniques made that kind of crazy operation unneeded for the vast majority of the year. And on the other side wind typically benefits this time of year... the temperature changes in spring bring stronger winds, and thus output is higher and somewhat more consistent. It's not at all surprising that wind would have brief periods of high output.
I think a lot of experts are looking at the economics of this and going "well shit, if environmentalists are going to kill every new gas pipeline then it makes a lot of sense to run these coal units another 30 years." And they're right. That's a huge change from even a year ago, when I think the common wisdom would have been most coal units would be imploded or mothballed within a decade. The vulnerability in our power grid is being laid bare for anyone paying attention. Even places like NYISO are warning they might have to take significant "out of market action" to ensure reliability (in other words, give large wads of cash under the table to fossil generators to ensure they stay operational for reliability purposes). None of this was unforeseen, but the speed of it has surprised even insiders. People don't realize it yet but their power bills are about to reflect the cost recovery for these extremely high prices (a process that typically lags a quarter or two). The effect is going to be devastating for a lot of people. It's also going to call into question the entire wholesale market premise, because regions like the American Southeast that have resisted markets are likely to have radically lower power prices due to their vertical monopolies being able to keep most of their nuclear fleets operational for fuel diversity.
