Categorizing sources into "renewable" and "non-renewable" doesn't change the math.

Centuries ago, our primary power source was lumber. Later it was coal and then whales and then oil. In the future it will be solar panels and fission and then fusion. The energy output of 1kg of fuel for a fusion reactor is many orders of magnitude more than what can be captured from burning 1kg of lumber.

And it's not a matter of "discovering a deposit". Hydrogen is the most abundant element in the solar system and in the universe.

Hydrogen is a medium, not a source. In many ways it's closer to the copper in a wire than to the crude in a pipeline.

To the best of my knowledge, hydrogen fusion is the source of well over 99% of all energy generated both in our solar system and galaxy.
