In practical terms how much of energy does one windmill in a wind farm produce per day. How many car batteries
worth?
Average wind turbine is about 3MW, with about 30% utilization, that comes to 1MW. In one day that is 24 MW-hrs.
A large car battery can store about 1000 watt-hrs. So if you used that energy over the length of the day, ie, started out charged, ended the day discharged, then you will get 1000 watt-hrs in a day.
divide the two and you get 24000. But at the end of the day, the wind turbine will still be running and you will have 24000 dead batteries.
