Solar power has begun to transform the world’s energy system

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

Does not necessarily need to be a battery. Flywheels, heat, and even synthesis of fuels are also solutions to the problem.

If you look at the energy density, cost/kwh, and lifetime maintenance of most of those, you'll find that batteries handily win. Further, batteries have room for innovation and growth in all those categories.

We won't, for example, make a more cost-efficient flywheel or heat storage. They are effectively as efficient as they'll ever be.

IMO, it necessarily has to be batteries. The other alternatives are nowhere near as good.
