Are windmills energy efficient?

17 years asked:

Is there a limit to the output of a windmill, considering there must be a way to build a windmill so the turbines are big enough to power a large motor, but also small enough to be able to turn quickly?
Is there a limit to how large the turbines can be?

If a school wants to convert to be 90% energy efficient, what is a good time line to reach that goal?

Lavender asked:

How many years to reach 25%, 50%, etc. energy efficiency?

And this would be for a school that does not have any solar panels, wind turbines, etc. but wants to convert to being energy efficient.

How energy efficient are induction cooktops?

C J asked:

My husband and I are in the process of building our home. We have several acres of land and are setting up wind and solar power for our home which has been estimated to meet our energy needs entirely. We want to be sure that we use as little as possible when it comes to appliances. Are induction cook tops a good option for us?
