It turns out school buses are at the leading edge of the transition to electric heavy-duty vehicles. But just in case there was any doubt, UCS crunched the numbers to compare the different types of school buses from gasoline and diesel-powered option, to natural gas, electric and yes – even propane. Why not 100 percent?

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. Under the no-new-policy scenario, sulfur dioxide and nitrogen oxides decline only by 27 percent and 18 percent, respectively.

The legislation committed nearly $400 billion to support, among other things, wind and solar power, battery storage, electric vehicles, and other clean energy technologies that will make a significant dent in US heat-trapping emissions. What are the main solutions?

With the clean energy transition already under way, the US electricity mix is set to continue changing this year. Solar power is expected to make up about half of all additions of US electric generating capacity in 2023, according to data from the US Energy Information Administration (EIA). I’ll start off with the good.

Critically, and as we’ll discuss in greater depth shortly, hydrogen combustion (as opposed to its use in fuel cells) also leads to greater emissions of nitrogen oxides (NOx), a toxic group of pollutants regulated under the Clean Air Act. All this is not to say there is no place for hydrogen in a clean energy future.

Fossil fuel, they argue, will still be needed in the near term as a backstop for the intermittency of solar and wind power and to keep consumer power bills affordable.
