    How does one provide power when the renewables don’t provide enough power (nights, etc)? Our current solution is natural gas. Nuclear is a huge step up as a carbon-free provider.

      Storage, there are many options. Pumped hydro is great for places with elevation change, molten salt is great for desert climates. Batteries, green hydrogen, compressed gas, etc.

      We’ve been storing energy for thousands of years. It’s not difficult in the way nuclear fusion, SMRs, or thorium are difficult.

      We’re also moving towards EVs. I’d like to see investment in using a fleet of connected EVs as a giant battery. Your energy company can pay you for making 10-15% of your EV battery available for grid storage and you can opt out if you need that extra range for a trip.

        The largest battery on the planet would power my workplace for less than two hours- if it could meet the instant demand, which it cannot.

        I’m all for energy storage, but I realise there’s a lot of work to do.

        The article talks about the coming droughts and water shortages. Pumped hydro is nice, if you have water.

          There’s evaporation, which can be mitigated by floating solar panels, but pumped hydro is a closed system, it doesn’t consume water.

          You save the water in a hole, then pump it back and forth. You can cover it with PV to stop evaporation

          This is also good for the droughts as you have emergency water.
