WINDMILL
Muslims did not invent the windmill. Windmills to pump irrigation water may have been in use in Babylonia in the 17th century BC. https://en.wikipedia.org/wiki/History_of_wind_power
Windmills were in use in Persia around the 10th century BC. http://www.solaripedia.com/13/80/persian_windmills_and_wind_towers_from_ancient_times.html

Muslims played no role in the invention of the tower windmill popular in the Netherlands.

WATER WHEELS
Romans in pre-Islamic Chemtou in western Tunisia set 3 horizontal water wheels into the bridge abutments.
The other type of waterwheel was the ship mill, where a water wheel is attached to the hull of a ship moored to a bridge, thus allowing it to operate regardless of the water level. These were popular in Europe during the 6th century, and from Europe spread to the Islamic world.
