non of the above answers are suitable for the windmills
4 – both of the above (photovoltaic panics can be used to generate electricity, and solar hot water panels can be used to heat water which then heats your home)
7 – passive solar heating
8 – true (it has to be formed by slitting water molecules)
10 – backup systems may be needed for times of low winds
Correct.
So, I’m just guessing for most of these,,,
4) both
guessing “true”
5) guessing “controller”
anemometer indicates a metering device
yaw drive indicates a directional drive
6) guessing “yaw drive”
7) passive solar
Chemistry is NOT my thing, but I know that it takes a lot of work/energy to use hydrogen fuel in getting the hydrogen on its own for energy use
9) ..it disappeared from the question; or did its energy dissipate
10) “back up systems may be needed in time of low winds”
there are also a number of assorted environmental problems in many cases
