1. 3/4 of energy usage is outside the transportation sector.
2. If we switch 3/4 of energy production away from fossil fuels, that will make a huge dent and make renewables even cheaper.
3. Once renewables get cheap enough, it may be cheaper to use a few kWh of solar to produce one kWh of ethanol than it will be to dig 1 kWh of oil out of the ground.

- Symmetry 11y agoProbably methanol. It's relatively energy efficient and it doesn't boil at room temperature like methane. https://en.wikipedia.org/wiki/Carbon-neutral_fuel#Production https://en.wikipedia.org/wiki/Carbon-neutral_fuel#Production
- oldpond 11y agoHydrogen goes boom, and ethanol is already straining the corn market to the limits. I can't see us turning every square section of arable land into ethanol production.
