MA utility's are adopting heat pump rates that reflect that winter-time heat pump use doesn't drive peak demand (which comes in summer).

This impressive study from @jpv.switch.box .box makes the case for why this make sense, and why the utility's should do yet more. www.switch.box/mahprates

"It saves us money, and will continue to save us money,” Steve Fate, president of the West Union District Energy geothermal network in downtown West Union, Iowa, told @mckennapr.bsky.social: insideclimatenews.org/news/2009202... 🔌💡

"The decarbonization agenda is not simply about reordering markets or industrial policies, but in fact represents the crucible for a new geopolitical order.” New axes of power for a new era.

We are on the verge of a new Cold War, defined not by an ideological contest over the proper relationship between politics and the economy, but over the metabolic basis of modernity. Call it the Green Entente vs. the Axis of Petrostates. My latest: foreignpolicy.com/2025/09/01/e...

With the construction halt on account of the ICE raid at the Hyundai LG Battery Factory in Ellabelle, GA, that project is the biggest project to slow this month.

Some major projects have slowed this month.

Natron Energy, which aimed to expand domestic manufacturing of sodium-ion batteries, ceased operations, halting operations at its Michigan plant and scuttling plans for its North Carolina gigafactory.

Headlining the projects that advanced last month is Rivian’s factory in Georgia, which broke ground on September 16.

The $6.6 billion factory employing 7500 people will be able to manufacture 200,000 EVs a year when phase one goes into production in 2028.

Since Trump took office, 80 projects adding up to $43.8B in investment and 50,813 job have advanced. Most are projects previously announced that have started construction or moved into production.

Only 33 new projects adding up to $8B and 13,310 jobs have been announced since Trump took office.

Chart plotting when clean energy manufacturing projects were announced and, for those that have been canceled, paused, or closed, when the disinvestment occurred (this chart excludes projects have just been delayed or reduced in size). It shows a big boom in project announcements during Biden administration and surge of disinvestment since Trump took office.

Trump 2.0 + 8 months. The slow down in clean energy manufacturing investments is still growing.

We are tracking 50 slowed projects adding up to $51.8B in investment and 50,381 jobs - up from 39 projects, $41.8B, and 42,429 jobs last month.

More on what has slowed and advanced below. 🔌💡

It should be way bigger news that Trump effectively killed any attempt by foreign countries to build new factories in the United States with this idiotic ICE move. Just incalculable long term damage.
