Nuclear energy is more expensive than renewables, CSIRO report finds::Renewable energy provides the cheapest source of new energy for Australia, a new draft report from the CSIRO and energy market operator has found.
There are tons of options for that, mainly energy storage such as batteries, hydro, and green hydrogen. Nuclear is not needed and too expensive among other things.
If you didn’t have sun or wind or whatever for weeks at a time, you’d need such an absurdly sized battery so as to be untenable. What do you do if you mainly have solar but it’s cloudy most of the winter? For these kind of things you will always need a certain amount of baseload power.
