In our 3rd video series “Dinner with Dan” we tackle the question many solar skeptics like our fictitious “Uncle Bob” pose: “What about nuclear? It’s reliable and runs all the time, right?” Here’s the scoop: we like nuclear’s zero carbon energy and high-capacity factor. There are just two major issues – waste and cost.
Since Uncle Bob may not care about polluting the plant with toxic radioactive waste for hundreds of years, we respond entirely with ECONOMICS that impact his wallet:
- A new unsubsidized nuclear plant: $180 / MWh
- A new unsubsidized solar plant: $60 / MWh
- And if you add batteries to the solar plant to get through the evening peak, the solar + battery plant is about $75/MWh – well under half the cost of the nuke, and far lower risk to develop, build, finance, and operate.
No wonder only a few new nuclear plants have been commissioned in the last 30 years in the US.
There’s buzz around new designs for modular nuclear plants. As an environmentalist, I hope they are successful, and have a solution to the waste issue. Cost numbers I have reviewed indicate they are very expensive…so not sure this approach can be counted on. Meanwhile solar, wind, and battery storage are scaling exponentially…and cost falling rapidly.
