Sure we do (ish). Look at Brazil, they pump more renewable bio-ethanol into their flex-fuel cars than they do gasoline.
- toomuchtodo 10y agoThey use sugar cane to produce their ethanol, which is far more efficient than corn ethanol in the US (which, might I add, is in no way sustainable). Are you suggesting we attempt to grow sugar cane, in the midwest, in the enormous quantities required to replace millions of barrels a day of petroleum consumption? Electricity will be the clear winner; we're simply awash in sunlight and wind.
- aianus 10y agoI mean, there are some things you can't run on electricity, like commercial jetliners. If we run out of cheap oil, we could use biofuels in those applications. For any application where electricity works I'm sure it will win too.
- mikeash 10y agoDoes that scale up to supply the fuel needs of the planet without starving a bunch of people to death? Renewable energy and storage does, it's "just" a matter of cost.
