Really cool view of energy production, usage and waste. 8 great takeaways, but my favorite is:
4. You don’t need a 1:1 ratio of electric to replace petroleum. That ratio is more like 1:5
The whole US transportation industry uses only 5.93 quads of energy to propel vehicles around. While it takes 28.3 quads of mostly petroleum to do so today, replacing internal combustion or jet engines with their much more efficient electric alternatives means you’d only need about 6 quads of electricity to produce the same movement. That can currently be made by wind, solar, or hydro (if they weren’t doing other things). To put it another way: to get rid of all of the petroleum energy used to run transportation in the US, you wouldn’t even have to double the amount of wind, solar and hydro.
FYI - Rejected energy is really energy losses, energy in the source that is lost and not used for the end service.
