Raw materials such as oil,gas,solar or even the wind that blows over ,air or dust with friction and percussion.
How we'll convert it all and keep it?
If energy is to heat.The opposite of heat is cold.
I think converted energy will keeping their best,without deterioration as long as possible is cooling.
Initially, the north pole or the south pole is probably the best answer.
But in the far future,on tour and space travel or even with the resort on planets are normally.
I think we should keep it around pluto or uranus.
You could not imagine that the spacecraft has many fly in the solar system is very flurry.
And of course!!!, it will require a lot of energy and surprise you.
