A new report by the prestigious US National Academy of Sciences concludes that the EPA’s 2009 endangerment finding was accurate, has stood the test of time, and is now reinforced by even stronger evidence:

Growing connections of AI/DC have now reached a level of complexity warranting a NERC alert, citing "rapid, major swings in load, experienced both in typical operations as well as in response to grid disturbances.” = more data + modeling needed.

So many companies do business in CA, this is a big deal, indeed. Investors can’t manage (at least well) what they cannot manage.

re: cow’s methane-laced burps, viable emissions reduction solutions are scarce. now though, forays into methane destruction - and even atmospheric removal - are gaining traction. i explore one pathway, from Ambient Carbon, here:

Ambient Carbon is doing the methane equivalent of point source carbon capture in dairy barns.

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 a signpost that grid planning + op are entering a new paradigm. System operators are rethinking how to maintain reliability in a BPS where inertia is no longer free and stability must be actively engineered.

A new report from the American Statistical Association reveals that federal statistical agencies—the government offices that collect and publish official data about everything from unemployment rates to immigration patterns—are in serious trouble.

I love renewable energy tech because it's either "use quantum mechanics and semiconductor physics to leverage the photoelectric effect" or "put three spinny things on a stick"

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.

New report finds, yet again, that "The United States is failing to build the high-voltage transmission infrastructure needed to support the nation’s surging electricity demand and growing strategic industries."

Today, Americans for a Clean Energy Grid (ACEG) and Grid Strategies released the report “Large-Scale Transmission Deployment Saves Consumers Money.”

This looks depressing, but there are reasons to be optimistic. Not naive, but truly hopeful.

Renewable energy technologies are cheap, and global GHG emissions are flattening.

We never had a better chance to get this done.

But a lot of work remains, and we cannot stop.

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.

This is a nice summary of the Spanish grid operator's reports on the May Iberian blackout. As with any big event like this, there were many interdependent causes, but the TL;DR is that 3 nuclear and 7 gas plants failed to provide the voltage control that the grid operator contracted them to provide.
