Well it seems that water is going to be a huge dilemma no matter what. This reminds me of Fallout3 where you gain radiation every time you swim or drink water and then have to use the RadX to get rid of it (Hint, make RL RadX, I hear there is a demand for it :lol)
Nuclear may be unsafe but no power is without it’s downsides.
Natural power such as currents, wind and solar are lacking in their supply power.
Right now there is some very heavy research and investments in Solar but it’s still years behind. FYI upstate NY just got a grant making it essentially national leader in research and development of solar.
