b.generate
c.use
d.store

Answer 1

I'd say use. You have to build an engine to turn it into useful work and you usually end up wasting most of it in the process. Unless your idea of use is to use it to heat yourself (which is really just heat transfer). Then that's not hard of course.

Transfering heat happens almost automatically. Heat flows from hot to cold.

Generating it is as easy as burning something or turning work into heat with friction-type forces.

To store heat, you need big insulators. This can be a bit of a challenge, too, so store is a fair answer I guess. Unless your insulators are very, very good, heat tends to flow from hot to cold.

Answer 2

I would say d. to store. While fossil fuels are stores of thermal energy, it took mother earth millions of years to create the fossil fuels such as coal and oil/gas. Once we burn coal, oil, gas or wood, heat is liberated and while we can use it to heat water and produce electricity, it is difficult to store it as heat.

Answer 3

Store. By nature, it dissipates.

Answer 4

It is option d, store :

Answer 5
