Intermittent, yes. Expensive, no. It's just not. It's a bit more expensive in the US because, hey, protectionism, but solar panels are now by far the cheapest

Intermittent, yes. Expensive, no. It's just not. It's a bit more expensive in the US because, hey, protectionism, but solar panels are now by far the cheapest source of electricity on Earth if you don't care when that electricity is delivered, and cheaper again if you're happy to have it in the Sahara or northern Australia. Solar power is now so cheap it is hard to conceive of any way nuclear power could ever compete against it where its advantages (24-hour all-year power) aren't relevant. Terraform's secret sauce is that they are designing their equipment to be cheap so it doesn't matter that they're only utilising it maybe 30% of the time.
