Why are fuels renewable and non-renewable?

It depends where the fuel comes from If it comes from a fossil fuel source, like coal, oil or natural gas, then it is non-renewable When we use these all up, there won't be any more If the energy comes from a renewable source, like sunlight, or wind, wave or other kinds of water power, then it is renewable After we use it, there will still be more tomorrow when the sun shines, or the rain keeps falling.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
