> making the grid green In my understanding, greening grids undergo multiple transitions simultaneously * from centralized to decentralized * from stable base load to hard-to-predict intermittent generation * from unidirectional to bi-directional (prosumers) Instead of having big nuclear (1.5GW+) or coal plants that produce 90% of the time, we'll have countless small renewable generation sites - a solar park with 200MW capacity already takes up a massive amount of space - but on average only produces 25% of the time, some biogas, a 300 MW windfarm, lots of batteries. Consumers and some businesses will produce electricity themselves using solar and might want to sell excess power back to the grid. Building out the physical infrastructure, software and financial system that make such a system run smoothly is an absolutely astounding challenge. We are simultaneously ripping out base load (in the coastal US and in western Europe nuclear is under threat, coal is being fought everywhere) while also demanding much more from the grid by switching all street mobility to electricity. In the end, the goal is to have a cleaner and more reliable system that provides power at competitive prices - this is an absolutely massive and extremely complex undertaking with technical challenges, political backlash ("don't build wind farms in my backyard!") and geopolitical problems (where do all the solar panels come from? How do ye compete with countries that use cheaper power?) along the way. I'm not buying that renewable electricity is necessarily cheaper (just looking at solar panels during sunny summer days does not count, we care about edge cases) and I think what you are proposing is very hard.
