- I find that very difficult to believe. Indeed, your figures appear to
- be inconsistent with this claim. At $1.3/W and 80% capacity, assuming
- an O&M cost of $.01/kWh, 4% real interest rates, and a 30 year
- lifespan the cost of power from wind turbines would be about $.02/kWh.
-
- At a 20% capacity factor, the cost comes to about $.05/kWh.
-
- The 20% figure is not just made up; it is the capacity factor at which
- current wind farms have plateaued, after increasing steadily for some
- years.
