  Depends on the type of solar panel. PV, no. Otherwise, yes.

  Solar, wind, tidal, RTG, DEC fusion are all options without steam

    Does hydropower count as cold steam?

    Well I guess all wind power is also steam at a very low concentration heated by a fusion reaction.

      the steam part is in the rest of hydrological cycle

      Hydropower gets its energy from evaporated water rising to the big steam in the sky.

    Wind and tidal is still just turbines.

      Yeah. One uses the passage of a gas over rotating blades. The other uses water as it flows.

      Neither use the passage of gaseous water, so theyre totally different!

        We never moved away from windmills basically. Only solar is completely different, besides niche impractical things like piezo crystals

  technically pv panels are also heat engines. this is why they need cooling
