An Interior Department memo is hampering wind and solar on public lands. It’s one of many federal actions slowing the build-out of cheap, clean energy.

Energy think tank Ember says utility-scale battery costs have fallen to $65/MWh outside China and the United States, enabling solar power to be delivered when needed.

In the lead-up to COP30, Kristina Costa, Jennifer Uchendu, Kobi Weinberg, and Elizabeth Andrews discuss global lessons in urban climate resilience and Chicago's potential as a climate refuge.

We assess the cradle-to-grave greenhouse gas (GHG) emissions of current (2025) light-duty vehicles (LDV) across powertrains, vehicle classes, and locations. We create driver archetypes (commuters, occasional long-distance travelers, contractors), simulate different use patterns (drive cycles, utility factors, cargo loads) and characterize GHG emissions using an attributional approach. Driven by grid decarbonization and improved electric vehicle efficiency, we are first to report electric vehicles have lower GHG emissions than gasoline vehicles in every county across the contiguous United States. On average, a 300-mile range battery electric vehicle (BEV) has emissions which are 31–36% lower than a 50-mile range plug-in hybrid electric vehicle (PHEV), 63–65% lower than a hybrid electric vehicle (HEV), and 71–73% lower than an internal combustion engine vehicle (ICEV). Downsizing also reduces emissions, with a compact ICEV having 34% lower emissions than an ICEV pickup. We present the first evaluation of LDV emissions while hauling cargo, showing that carrying 2500 lbs. in a pickup increases BEV emissions by 13% (134 to 152 g CO2e/mile) compared to 22% (486 to 592 g CO2e/mile) for an ICEV. Emissions maps and vehicle powertrain/class matrices highlight the interplay between vehicle classes, powertrains, locations, and use patterns, and provide insights for consumers, manufacturers, and policymakers.

Renewable power executives say difficulty getting permits, rising costs due to tariffs and the end of key tax credits are making it tough to plan.

Sunshine on a Cloudy Week

Overturning the basis for America’s tailpipe emissions rules could actually raise prices at the pump — according to the Trump administration itself.

On the hottest day this year, behind-the-meter solar panels and a growing network of batteries helped prevent blackouts and saved consumers millions of…
