I would argue a nuclear one as well. Energy independence and abundance should rely on a number of sources of energy.
Nuclear is near dead if the new geothermal tech from fracking works out.
20 years from now and billions of dollars over budget? Or by variety do you mean wind, solar, geothermal, and hydro?
The Chinese already have a 125e Small Modular PWR that would be excellent for small islands like those of the Caribbean. It is the Linglong-1 [0]. I believe the first one cost 800 million dollars. It will be interesting to see the price reductions as it goes into serial ptoduction.
