In a recent study, researchers from the European Environmental Bureau (EEB), the Stockholm School of Economics (SSE), and the Potsdam Institute for Climate Impact Research (PIK) questioned the planned development of new nuclear capacities in the energy strategies of the United States and certain European countries.
Pumped hydro + Renewables are the best bet currently. Both are cheap and can handle day to day fluctuations easily. This still requires some baseload power to get through a period of dark/calm days though. Hydro dam reservoir (basically giant battery) will be key to limiting the amount.
The real kicker is that drilling tech and geothermal tech advances. These have the ability to be cheaper than fossil fuels within 5-10 years and fill in the baseload power gap.
Future is coming, net zero is possible, would appreciate more funding in this direction.
