As far as i know, prob using matter and anti-matter to create energy. But I'm a literalist...lol
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?
Sources of energy given by nature are non renewable, i.e which cant be recycled for example coal,petroleum,oil,diesel..
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.
