Resource depletion? But the planet is enormous - and we

Miners seem to tell a rather different story.
Past meteorite impacts are involved, I understand.

And E=mc^2, and 'c' is enormous - so gigantic energies can be created simply by smashing atoms together.

If you are referring to nuclear fusion, it doesn't seem that we are

There is no shortage of coal - and there's a huge natural
fusion reactor nearby. So, there's no great hurry.
