Check out the Department of Energy’s Petroleum Reduction Planning tool (PREP), a nifty calculator that helps you reduce your fuel use.
You set a goal for how much fuel you want to save and choose one or more methods of getting there. The methods are fuel economy, reduced travel, different fuels and fuel blends, and hybrid electric vehicles. It also lets fleet operators calculate truck stop electrification, idling time reduction and onboard idle reduction.
The interface is adequate but we’d like to see it be a little easier to use and it helps to know that VMT stands for vehicle miles traveled, but overall it should help a lot of people cut their fuel use and with it their greenhouse gas emissions. We’ve added the calculator to the “What you can do” section of ERN’s Resources page.
