How much energy does a windmill give?

Question

How much energy does a windmill give?

Answer 1

depends on the size of the blades and the power of the alternator/generator you are using.

Answer 2

just one windmill won't give much energy, even in the presence of high winds. that's why 'wind farms' are set up to produce energy for commercial use on a large scale

Answer 3

None at all ,unless you call grinding an energy

wind mills were mills operated by wind power to grind corn and wheat ,And the guy who owned them was called the Miller.

the few that are left are now tourist attractions ,private home or restaurants

Are you perhaps referring to wind turbines or wind generators

how much electricity they produce depends on the size ,and i don't know the answer o that question.

Answer 4

Wind-Mills grind things,

this does not usually need a lot of energy, but need high torque at low speed. A lot of skill is needed to keep the millstones at the right speed and distance apart to avoid oveheating the grain, or causing sparks. But the finished result is nutritianally better than roller mills.

Wind turbines require low torque at high speed to turn the generator as fast as possible, so they have only 2-3 slim areofoil blades. The amount of energy available is proportional to the Swept area and the wind speed.

Answer 5

How big is the Windmill.

Answer 6

The largest wind turbines can generate up to 6MW of power (for comparison a modern fossil fuel power plant generates between 500 and 1,300MW).But this energy is negligible. that is why large windfarms are set up

Answer 7

Depends both on size and availability of wind.  The largest here are 25 MW units.  The blades are about 60ft and the generator housing is the size of a city bus.

25 MW is its rated output X 24x7x365 for annual potential output, actual annual output is usually around 20-25% of total potential output (the wind don't always blow).

Answer 8

Seeing as how your question is so vague.

Not Enough.
