Where will the power come from if wind is not blowing in wind farms?
The windmills are designed to be part of a big electrical grid, with various parts reinforcing other parts. The wind doesn’t stop over the whole country at once, so if the wind dies in one place, power can be moved in from other places over the national grid. That electricity may come from other windmills, or from more traditional electricity generation sources (coal & nuclear, for example). You can’t really store electricity efficiently in batteries, but there are other ways to smooth out the curve of demand. For example, one use of windmills is to store water in water towers, which provide water pressure. If the wind dies, you can stop storing water and use your reserves. Then, when the wind picks up, you can resume pumping water, without relying on the other sources. Windmills are only part of the total infrastructure. There will always be need for traditional power generation, though we can get away with a lot less of it. We’ll need more windmills to handle peak demand and local sh
