Yet, in order to deliver that "free" energy to you, you must also pay:
a. For the federal subsidy that makes wind energy economically feasible for those who invest in the wind farms.
b. A rate premium to the utility who delivers that that "free energy" to you, because they are forced to purchase a specific percentage of their total energy from that wind farm at a premium price.
c. Yet another rate premium for the back-up plant that the utility must build and have standing by in order to have an alternate energy source at hand for when the wind farm can't deliver its "free energy".
Q: How does all this make economic sense?
A: It doesn't.
Utilities pay a contractual rate for wind energy, which should be included in the mix of their rate to consumers. Any premium above this for "green" energy is a marketing ploy by utilities which they simply pocket.
Utilities must have back up and reserve generation anyway, for peak demand periods and/or when other plants are taken offline for scheduled maintenance.
