Wind Farms -- September 15, 2019

See this post.

A reader commented after reading the EIA prognostication at that post:
The US Energy Information Administration (EIA) claims that wind power can generate electricity for 8¢ per kilowatt-hour (kWh). However, this is based on poor assumptions and glossing over important realities.

It assumes average wind turbine lifetime is 30 years, the same as a conventional fossil fuel power plant. In reality, most turbines last only 15 years, and less offshore. It ignores the cost of backup power. It includes no cost for transmission lines from wind farms to distant cities. Most significantly, it omits subsidies.

A 2016 Utah State University study shows the following extra costs omitted or miscalculated by the EIA for wind power: 15-years not 30-year life expectancies (US 7¢ per kWh), backup power (at least 2.3¢ cents if the back-up is natural gas), transmission costs (2.7¢), government subsidies (23¢).
All that means the real cost of wind power is a staggering 43¢ per kilowatt hour! That’s seven times the cost of natural gas-generated electricity!
The Utah State University study will download as a pdf.

To the best of my knowledge, wind farms
  • pay no royalties to anyone but the surface owner;
  • return any cash to the local community; and, 
  • require subsidies, tax breaks, mandates to survive.
