Renewable energy is great, but we're not replacing fossil fuels with it, we're just adding more energy usage. And our energy usage is destroying the environment.

Don't let these advancements in solar make you think things are getting better. We need to reduce fossil fuel usage, not just increase solar usage.

What replaces fossil fuels is some kind of breakthrough in batteries. At the moment its getting better every year were currently at less than $100 per KWh which is crazy but needs to be improved for allowing more off the grid energy consumption

We are also going to need a breakthrough in how batteries are produced and disposed of. Otherwise the environmental impact of the many millions of batteries themselves may prove unsustainable too.

Maybe better disposal practices. Regulations standardizing batteries would also do a lot of good.

But really, we simply need a lot of virgin batteries regardless because we don't have enough. Recycling and disposal will only really take off once the market is mostly saturated (which we don't appear to be anywhere near).

I'd also point out that modern LiPo batteries are 90% recyclable with no special techniques needed. That's because by weight, the batteries are mostly iron and nickel. Recycling them is really as simple as just melting them down. It only gets tricky if you want to collect the lithium, silicon, and other trace materials (and there are already recycling plants that are handling that).
