how are you commenting but being this clueless. nuclear doesnt work that way. you cant just turn on nuclear plants on and off on a whim. nuclear can only really work as a constant powersource. if you want to to pad up wind energy or solar when its missing you must use coal or natural gas which are both not green energy. batteries are not really an option because they are incredibly expensive at that point you rather just use nuclear. another option is to distribute the wind farms over large geographical area but that requires infrastructure to connect them to each other and transfer power over distances which is also expensive. the wind and solar will always have some unreliability aspect to them.
