As far as i know, prob using matter and anti-matter to create energy. But I'm a literalist...lol
Burning all Republicans in cremation champers. They are useless humans and never contribute to life other than waste the air I breath. We would save so much energy with these fools put extinct.
A resource that has a limited supply and a slow rate of renewal.
Any thing we use as fuel that the Earth can not reproduce or replenish. Fuels like crude oil and natural gas can not be replenished but trees and corn, to name a couple, can be planted and grown and therefore be and endless resource.
Are you done studying for tomorrow?
Anything depleted as an energy source, just like coal, etc.
Are you kidding me?<br />
Stuff like oil, coal etc. Burns up and you can't use it again. You have to wait a million years for nature to produce more of it.
