Hydro is just more dense steam, wind is less dense steam, it's steam engines all the way!
The only really new kinds are thermocouples (mostly garbage) and solar panels (poor efficiency, but abundant fuel).
Some fusion might end up using magnet pumping, which is basically just a plasma powered piston.
The best solar panels are getting at or above the efficiency of converting nuclear heat to electricity (about 1/3) so they probably shouldn’t get that poor efficiency label.
Not OP. I guess it depends on the frame of reference. Comparing to other inefficient methods it might seem OK :)
