Those comparisons have been done and they always end up with an energy mix between hydro, nuclear, solar and wind - not 100% wind/solar. It isn't enough to build solar and wind, you also have to build backup. This is currently done by coal and gas but in the future it has to switch to climate friendly sources of energy. A hydrogen economy is very very expensive. Here's an example: https://www.sciencedirect.com/science/article/pii/S2542435118303866 https://www.sciencedirect.com/science/article/pii/S254243511...
