Oil will never run out.Fossil fuel is going to run out. So renewables is a question of when not if and seeing has we have to get there anyway why not now on the off chance science is a thing and we are messing with the planet a bit too much?

Eventually it may become uneconomic to extract but World oil consumption is falling.
