The energy costs here have adjusted alternative energy with tax credits. The nuclear energy price assumes that the facility lasts 20 years instead of 40 to 60 or more years which has been the actual experience.
Assumptions in the Estimates
Nuclear is the carbon friendly conventional power source for baseload power. The alternatives for baseload power that are carbon friendly have supply issues (geothermal, landfill gas, biomass and fuel cell)
US energy subsidies.
