Solar and Wind To Top Coal Power In US For First Time In 2024 (evwind.es) 67
An anonymous reader quotes a report from REVE News: The U.S. Energy Information Administration (EIA) expects, for the first year on record, combined electricity generation from wind and solar to surpass generation from coal in 2024. EIA expects solar generation in 2024 to increase 39% (228 kilowatthours) from 2023, driven by continued increases in solar capacity. "Renewables, particularly solar photovoltaics, are growing rapidly and making large contributions to electricity generation," DeCarolis said.
EIA expects natural gas prices to be $2.77 per million British thermal units this winter, about 23% lower than previously forecast. The winter season is off to a warmer-than-expected start, so U.S. households are consuming less natural gas for heat than expected. The lower natural gas consumption is also contributing to rising U.S. natural gas inventories, which typically results in lower prices. "We're seeing record domestic natural gas production paired with lower-than-expected natural gas demand, and we expect that is going to push prices lower this winter season," DeCarolis said. EIA will publish its next STEO on January 9, 2024, including the agency's first forecasts for the energy sector through 2025. The full report is available on the EIA website.

Indeed. TFA was written by an idiot.
America consumes about 4 trillion kwh of electricity annually.
In 2021, 434 billion kwh came from wind (about 10%), and 144 billion kwh came from solar (about 3%).
What I think TFA is trying to say is that solar will increase by 39% to 228 billion kwh between 2023 and 2024. But that is almost certainly wrong. An increase that big in a single year is not realistic.

The percentage of the nameplate capacity that is delivered is not a good metric for reliability. Consider, for instance, that a plant generating peak capacity on demand, to the amounts required, would appear much less reliable than a plant which is generating constantly, regardless of demand. To understand reliability, you need to measure the expected required output over the actual output; or the percentage of time when no output was possible at all; or a variety of other measures I can think off.

Neither. The cited estimate is from the EIA website [eia.gov] where it discusses actual production not any sort of capacity.
We expect solar and wind generation together in 2024 to overtake electric power generation from coal for the first year ever, exceeding coal by nearly 90 billion kilowatthours.

Um, no. That is almost nothing. Here is the article quote that as 39% in it:
"We expect that the 23 gigawatts (GW) in 2023 and 37 GW in 2024 of new solar capacity scheduled to come online will help U.S. solar generation grow by 15% in 2023 and by 39% in 2024"

I wonder if one of the reasons that the plants are kept around is that they can cold-start the grid. Not all power plants can start up from a grid with no electricity on it. For example, Finland uses a natural gas furnace to cold-start up some of their plants for additional capacity in the winter.

I am not trying to be a pessimist. It is just that a lot of people think that we have all the solutions in hand to end fossil fuels, but they are not looking at the real numbers. If we are going to do this, we need a lot of R and D in a lot of areas. Heating is a big problem because the demand does not line up seasonally with the supply of sunshine. If we have enough solar panels and batteries on the grid to supply energy for heatpumps to every home throughout the lower 48, then we will have a 2x or 3x overcapacity during the summer. We should be looking at what we can do with that overcapacity. Desalination? Synthesis of CO2 and H2 into synthetic natural gas (and longer chain hydrocarbons for jet fuel)? Not saying I know the right mix of technologies. I am just saying that we have a long way to go, and the full picture of a solution has not yet emerged or been proposed by anyone.

I think that will be a good problem to have. One option: grinding up basalt to spread on fields. It improves the soil and pulls CO2 out of the atmosphere to form stable carbonates, sequestering it.
