If renewable energy becomes abundant/cheap enough, you can convert electricity into hydrogen or other high energy density chemicals.
- vkou 10y agoHydrogen is a nightmare to work with, and store. Other high energy-density chemicals tend to be complex hydrocarbons... So you're still burning oil - it just happens to be made from coal, or algae slush, or whatnot.
- Neeek 10y agoAlgae slush is carbon coming from our current system, our current atmosphere, it is renewable. Fossil fuel is releasing carbon from and external source (external on a human timescale at least). It will be essential in creating a renewable replacement for oil. Burning hydrocarbons is not the issue. Burning hydrocarbons that were extracted from the atmosphere millions of years ago, is.
