Considering that transportation fuel is a relatively small cost of product , using something like biofuel is easy.
- schiffern 9y ago>using something like biofuel is easy. Or better yet, an EV truck (ala Tesla Semi) ultimately powered by stationary PV. Per the video, studies vary on whether biofuels input more or less fossil fuel energy as they output in biofuel energy. But in the best case it's still terribly inefficient, requiring 30-200x more land versus using PV arrays to power electric vehicles.[1] And using rooftop PV (sometimes dismissed because it's more expensive) reduces the resulting pressure on wilderness and agricultural land by 'reusing' land that's already been developed.
