Wind displaces hydro, not fossil fuels

As a follow-up to an earlier post looking at the generation patterns in Spain and northwestern USA, here are a couple more pictures:

It's pretty clear from the Spanish graph that it is hydro power that is varied in response to fluctuation of demand as well as of wind power.

And the same thing is clear from the Bonneville graph: It is hydro power that is varied in response to both demand and changing wind. The thermal power generation line remains virtually constant.

In other words, wind power on the grid is not reducing the use of fossil fuels.
