Kinetic energy is exactly what’s harvested, which is why modern wind turbines are not far off the theoretical limit of the amount of energy that can be extracted. (Betz’s law)

By taking energy from wind, you slow it down. Slow it down too much, and it can’t get out of the way in time for new air.

What they do here for (a good amount of) home car chargers is read out the electricity meter using their serial port and dynamically adjust the charge current to never take more than those 3x25A.
