Which fuel has the shortest span of renewability?

A) coal

B) nuclear

C) oil

D) solar

I believe the answer is: Solar

Solar is the type of energy that derived from the heat energy created by the Sun. So, the renewability for solar energy is around 12 hours time frame considering that the sun is up that period. The other options need years before they could be renewed.

Either coal or oil because eventually we will run out of them but we can't run out of solar or nuclear. Most likely oil
