How many watts of electricity can a typical windmill produce?

Answer 1

The typical wind system delivers roughly 8 to 10% of what systems are rated at 28 MPH. If the wind gusts over this amount the system shuts down. If the wind falls to 14 MPH you see 10% of rated. At 11 MPH you see nothing. To compensate for this issue, fossil fuel plants run in the background. The energy they use and CO2 output is ignored because wind generators are connected.

The overall effect is that no useful power is ever created if you consider the fossil fuel plants idling. Check out the number of birds killed each year by wind and you have a really bad system. They should be banned.

Answer 2

With a 25% capacity factor, a 1.5-MW turbine would produce

9 kWh in one day.

Answer 3

The larger systems can develop 1.8 Megawatts of power of the wind is blowing at exactly 28 mph and perfectly steady.

This same system sitting in a far more normal wind average of 14 mph will provide 180 kilowatts of power (10%)

If the wind has gusts as high as 31 mph, the wind system provides no power.

If the wind falls to 7 mph average the system puts out 18 KWH's of power

Below this they also produce no power.

Answer 4

Enough to light 350 homes if the wind is at exactly 28 mph all day

If the wind reduces to 14 mph that number drops to 35 homes

If the wind drops to 13 mph that number is 20 homes

Fossil fuel plants run at 100% at all times to make up for these variables.
