Nice article about NASEM review of the endangerment finding by @insideclimatenews.org National Academies Will Review Endangerment Finding Science insideclimatenews.org/news/0708202...
Andrew Dessler, director of the Texas Center for Extreme Weather at Texas A&M University, said the new controversy that the Trump administration had stirred around climate science was a fitting subject for a fast-track effort by the National Academies.

“The National Academies [were] established exactly to do things like this—to answer questions of scientific importance for the government,” he said. “This is what the DOE should have done all along, rather than hire five people who represent a tiny minority of the scientific community and have views that virtually nobody else agrees with.”

It’s hard to find a trend in the electricity system right now that *doesn’t* point to near-term rate hikes if not a broad affordability crisis. That’s a serious problem for climate policy, but also the American economy writ large. I wrote about it: heatmap.news/politics/ele...
What is less well understood is how poorly the United States is prepared to match this rise in electricity demand with an equivalent increase in supply. To some degree, American electricity prices are already rising: So far this year, utilities have received or requested permission to increase customers’ bills by $29 billion, according to a July report from PowerLines, a think tank and advocacy group. That’s a large number in its own right, and it’s more than twice as much as had been approved at this time last year.

But when you look across the power system, virtually every trend is setting us up for electricity price spikes:

The supply chain to build new natural gas power plants is backed up. Virtually all new utility-scale gas turbines are spoken for until the end of this decade, as Heatmap News covered in February.
U.S. natural gas supplies will come under more strain in the next few years as fossil fuel companies export more of the fuel abroad. From 2024 to 2028, North America’s liquified natural gas export capacity is projected to double.
Many of the key components to build more grid infrastructure — such as copper or steel — have surged in cost due to Trump’s tariffs and self-induced trade uncertainty.
The federal government has become a less stable fiscal and financing partner for energy producers and distributors. On Wednesday, Energy Secretary Chris Wright killed a government loan guarantee for the Grain Belt Express transmission project. Why? “To ensure more responsible stewardship of taxpayer resources,” but also because President Trump asked him to.

How much could clean electricity adoption change without tax credits? Existing modeling suggests that annual additions could slow by roughly half for many technologies to 2035. But these studies omit recently proposed excise taxes, which could further reduce project deployment.
