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?

That means that, for a plant to generate the same amount of electricity, it needs to burn more of a gas-hydrogen blend. Electrolysis involves using electricity to separate water into hydrogen and oxygen. But where that electricity comes fromhow its generatedmatters. Because electrolysis requires large amounts of electricity.

Here are five reasons offshore wind is a good thing for all of us. Offshore wind provides abundant, zero-carbon electricity I think most folks understand that wind turbines generate electricity by harnessing the power of the wind (for a handy primer on the mechanics, see here.) Source: NREL 2.

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.

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.

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.
