And you need to store the power somewhere for nights and cloudy days. Energy storage ain't cheap, or even feasible enough for an all-solar-and-wind power system. I don't know why solar advocates continuously ignore this point.
- pfdietz 6y agoBatteries for short term storage, hydrogen (stored underground and burned in turbines) for long term storage. Combined cycle is 10% of the cost of a nuclear plant of the same capacity; simple cycle just 5%, so one can back up the entire grid with hydrogen and still pay lower capital cost than for a nuclear grid. https://model.energy/ https://model.energy/
- credit_guy 6y agoNot according to the EIA ([1] page 8 Table 1b). The cost for 1 MWh of nuclear energy is $63 and for solar $30. The solar cost includes 4 hours of storage (no long term storage).

- pfdietz 6y agoThat nuclear number has no credibility. AP1000 and the EPR were also promised to be cheaper, but were 2-3x times that.
