Our re­new­able en­ergy sources are es­sen­tially in­di­rect nu­clear fu­sion. With­out baseload re­new­ables, such as geo­ther­mal and hy­dropower, we will need a mas­sive eco­nomic in­vest­ment into grid stor­age for wind and so­lar power. That cost is some­thing nu­clear com­petes with.

Most im­por­tantly, the pos­si­bil­i­ties of nu­clear en­ergy make it the ideal fu­ture. We are now de­vel­op­ing fast breeder fis­sion re­ac­tors and mas­sive stel­lara­tors for hy­dro­gen fu­sion, which make backup gas tur­bines look like clunky, in­ef­fi­cient and pol­lut­ing Mid­dle Ages tools.
