Renewable energy is easily able to provide enough energy sustainable. Batteries can be recycled. Solar panels are glas/plastic and silicium.

Nuclear is feasable, fusion will happen in 50 years one way or the other.

Existens is what it is. If it means being able to watch cat videos, so be it. We are not watching them for nothing, we watch them for happiness.

Well that's just your opinion.

Yes we can generate electricity, but it would be nice if used it wisely.

Nonetheless, survival can't be the life goal after all the moon will drift away from earth in the future, the sun will explode and if we survive that as a species, all bonds between elements will disolve.

It also can't be about giving your dna away because your dna has very little to no impact over just a handful of generations.

And no the goal of our society has to be to have as much energy available as possible to us. So much energy, that energy doesn't matter. There is enough ways of generating energy without a real issue at all. Fusion, renewable energy directly from the sun.

There is also no inherant issue right now preventing us all having clean stable energy besides capitalsm. We have the technology, we have the resources, we have the manufacturing capacity.

To finish my comment: Its not about energy, its about entropy. You need energy to create entropy. We don't even consume the energy of the sun, we use it for entropy and dissipate it back to space after.
