I don't know about irreversibly, but the remarkable and consistent gains in solar technology especially are extremely exciting.
As soon as one of these prototype next-gen batteries hit, that's it for fossil fuel.
It's already not worth it to continue using fossil fuel commercially, but as soon as the next-gen power storage is able to be produced on scale, power plants are changing, phones, computers, cars, everything's going to change.
I can't see that being more than a decade out, but even if nexgen battery tech doesn't hit, the constant improvement on s***** traditional battery tech now is improving rapidly.
It is a very exciting time and energy production and storage.
