Changes to California’s Electric Truck Proposal Could Reap Huge Climate and Air Quality Gains

Union of Concerned Scientists

The Advanced Clean Fleets (ACF) rule has the potential to significantly reduce climate-warming greenhouse gas (GHG) emissions as well as harmful air pollutants like fine particulates (PM2.5) These trucks regularly operate along industrial corridors – areas that often flank communities disproportionately impacted by air pollution.

Solar energy output of India is reduced significantly by air pollution

Physics World

Air pollution in India is reducing the energy output of some solar panels as much as 52%. That is the conclusion of researchers who have modelled the effects of particulate pollution on solar irradiance in 2001–2018. Having abundant insolation, the country was ranked fifth in the world for solar energy capacity in 2020.

Minnesota: Will This Be the Year for a 100-Percent Carbon-Free Electricity Policy?

Union of Concerned Scientists

Now it’s on to the state Senate, where the question is: Will this be the year Minnesota sets a path toward 100-percent carbon-free electricity? Minnesota can join other leading states By enacting a standard for 100-percent carbon-free electricity by 2040, Minnesota can join other leading states who have updated their clean energy policies.

Ask a Scientist: Two Dozen States Can Meet 100 Percent of Electricity Demand with Renewables by 2035

Union of Concerned Scientists

Nearly all of the alliance members have a renewable electricity standard (RES), which requires utilities in their jurisdiction to increase their use of renewable energy to a particular percentage by a specific year. From 2020 to 2040, solar generation in these states jumps nearly ninefold and wind generation more than sevenfold.

Dear Maryland: It’s Time to Drive Clean Trucks and Buses

Union of Concerned Scientists

Much of this air pollution comes from diesel trucks rumbling along the state’s many highway corridors, in particular I-95 which connects many major cities along the East Coast. This all makes Maryland one of the deadliest states for diesel particulate pollution. A @LightningeMtrs transit cargo van (electrified Ford transit van).

Has Gasoline Use in California Peaked?

Union of Concerned Scientists

More efficient (and cleaner) gasoline cars are part of the reason why gasoline use is down, but the increasing number of electric vehicles being sold in the state will likely drive gasoline use down even further. But a growing share of the reductions is likely due to the increasing sales of electric vehicles (EVs).

Powering the Data Boom: How Will the Grid Keep Up?

Union of Concerned Scientists

I work in the electric utility sector, specifically on the grid issues that shape our energy supply choices. I heard some early warnings of data center growth running into grid limits first from tech companies and then from electric utility planners. This growth is a jolt to the usually slow-moving electricity sector.
