This is, I think, one of the best ways to go towards clean energy. I would start with (gradually) eliminating gas plants and coal plants. There are already some countries doing this but I think the process needs to be accelerated. What are your thoughts on this?
I agree. I think that governments all over the world should be focusing on offering financial incentives for utilities to switch to renewables. This is the biggest, quickest way to speed this up. Even if a government will lose some money at the beginning, over time we all win.
I would also go for converting coal plants to hydrogen or biomass so we can reuse these old plants and not just close them down (if possible, of course). Governments should be investing heavily into wind and solar farms as these can produce tons of energy that is much cleaner.
