    Presumably next question is….how much of the capacity is available when, and on average?

      the newer sites are averaging between 35 and 45 percent.

      overall, cost per kwh is now cheaper than new coal – way cheaper than new nuclear.

      All of the capacity is available all of the time – or close enough because the reliability and up-time of wind turbines is near-100%.

      If you mean, “what is the capacity factor of wind turbines”, that depends on the site. One wind farm in Scotland has hit 58% over the course of a year – but most wind farms are in the range 25 – 45% and newer, larger, more advanced turbines are constantly pushing that up.

    Thank you both. Personally, I am more of a fan of high-altitude wind power (eg Kitegen) as less invasive and more reliable. Let’s see how it pans out.
