Chemical power generators are not used due to the far lower total available energy.

The last supply of available energy or data is thrown out.

But the total energy available, should they collide, is not equivalent.

By the time we eat them, about 90% of the available energy has been used or lost.

There is more energy available than man can ever use.

It would have no states of lower energy available to it!

This has to be the most expensive renewable energy available.

Thus the total amount of energy available to make particles becomes very large.

There is simply not enough available energy in the world for the population of the planet to achieve western living standards.

He pointed out that a civilization is limited by the energy available to it.
