Answer 2

As we are becoming more modern and industrial day by day the cosumption of energy per annum is also increasing accordingly.

There are two types of energy sources;

1)Direct Energy Source

2)Indirect Energy Source

Direct energy sources are instantly self usable and producable energy.

But on the other hand indirect energy source is produced by someone else in an industrial scale and that eenergy is provided to us.

Fossil fules like coal (mined rocks)are direct energy source becasue we can burn it and generate heat energy by ourselves.
