I'm assuming that chart covers everything.
Not just electricity. Nuclear currently makes up around 20% of our power grid output. 500 AP1000 reactors would pump out around 500,000 MW 24/7. Hydroelectric makes up roughly 8% of our electrical output, but if existing plants were upgraded with state of the art technology, then it could probably be pushed up to around 10%.We would also need to build several breeder reactors to reprocess the spent fuel for reuse.
Complete and total energy independence within 20 years for well under $1 trillion. Now that's a plan!
