We really should stop using the same word for two things with such different characteristics. Hydro/geothermal: nice steady power but not easily available ever

We really should stop using the same word for two things with such different characteristics. Hydro/geothermal: nice steady power but not easily available everywhere. Wind/solar: available everywhere but variable output. Obviously it's easy to run a city on "renewables" if you have a convenient dam, but if you only have wind/solar it's more challenging.
