And solved!

Nuclear power can go in as a Renewable, so no expectation for a meltdown on a double.

The probability graph does odd things*, but that’s cool because it neatly splits the renewables into three groups - a pretty reliable nuclear reactor, a bunch of mostly reliable Big Renewables - think hydro, wind farms, tidal stream ect and a bunch of rather less reliable micro-renewable. They’re less powerful, but can be ‘bolted on’ to other infrastructure like houses and factories so they get more and more useful as the game goes on.

Rockin!

*there is no 'zero’ fossil fuel plant because it’s just way too reliable. 80% chance of generating every player’s turn. The game would become 'see who gets that card, they win’.
