Green Energy

You gotta have reliable baseload energy. Traditionally, that has been hydro in blessed regions, coal and gas in other regions, and nuclear if your country has the funds to do so.

The key is to always have baseload power for dark winter months, weeks of bad weather, or heat domes and forest fires, where you may find yourself not having sun or wind for extended periods of time with incredibly high demand on the grid (for AC!).

My two cents is that nuclear energy is worth it for clean, reliable energy that doesn't hose all of your rivers. We will need some hydro for water reserves and power, but a diverse energy mix that doesn't rely on hydrocarbons is the way forward, imo.

Baseload of hydro, nuclear, geothermal. Solar and wind with battery storage, pumped storage, green hydrogen. Rooftop solar. Greenscapes in cities to keep heat down and absorb rainwater so it doesn't mess up combined sewage pipes.

Heat pumps and proper insulation for homes and buildings. Ebikes for short range commutes of 1-45 miles. Puts a lot less strain on the grid than EV cars, too.
