>> today solar and wind is cheaper in the western world. I’m afraid this is only true for the US, let’s not forget almost all of Europe is as north as Canada or north US. In order to compare the cost we cannot just compare the price to install a certain capacity.
You must also factor in how much extra capacity you need to build. When we look at the Germany[1], on the best month, their solar produce half of the installed capacity and solar never goes higher than a third.
And that’s for the best month. Germany has already invested 600 billions, does it need to go 5 five folds ? Maybe less as the costs are decreasing. It seems like that money invested in nuclear would produced much more and prevent spending what’s starting to look like an entire gdp invested into renewables. 1: https://app.electricitymaps.com/zone/DE |

We can estimate the cost of storage to deal with intermittency and seasonality, and renewables will likely come in cheaper than nuclear by the time any nuclear plant whose construction was started today would come on line.

As modeling gets better, renewables look better, as there are more and more ways found to work around the seasonality and intermittency problems.

> With every iteration in the research and with every technological breakthrough in these areas, 100% RE systems become increasingly viable. Even former critics must admit that adding e-fuels through PtX makes 100% RE possible at costs similar to fossil fuels.
