14 years and 35 billion (combined with #4 which has not been finished) and didn't generate a single kWh in anger until now. Put the same investment into renewables and it would generate similar or greater energy and would start doing so within a year.

The argument against nuclear now is not about safety. It is about money. Nuclear simply cannot compete without massive subsidies.

Renewables and nuclear play different sports.

Renewables are better for most of our needs but there is a backbone need of base power. Nuclear is an expensive but clean way to provide that.

By my very very very rough calculations, you could build a large scale solar farm with 3x power output and have enough money left over to build a 33GWh battery. That would more than cover a continuous supply of 1GW.

Unless there are a few cloudy days in a row... My panels produce a lot less than normal during cloudy days.

Proper analysis has been done on this and it's very achievable. With sufficient storage (which is lower than you'd expect to need intuitively with a full grid + mix of renewables) solar + wind in combination are the cheapest forms of power today. E.g. Here's a cost analysis by csiro (aus government science body), that includes an optimisatic estimate of costs for nuclear in 2030 with widespread smr adoption. https://www.csiro.au/en/research/technology-space/energy/energy-data-modelling/gencost

Renewables with integration costs are the cheapest by a good margin
