Wow, that's one of the most dishonest graphs I've seen in a while. Note the highlighted areas.

The scale on the two lines differs by over an order of magnitude. Although it appears at first glance that there were short times where wind generation exceeded total demand, by showing the blue line above the green line, in reality, wind generation never rarely met even 10% of total demand.

Good observation.

I would only call it "dishonest" if the author were misrepresenting it to prove that wind was a viable energy source. He isn't. He's using it to illustrate that wind provides its lowest amount of power at peak demand and vice versa.

I'll grant you it's poorly designed.

Too bad they can’t figure out how to store the energy. AC power has a lot of merits but storage is one of it’s limitations. And conversion to DC and back to AC is not the best solution.

How is it dishonest? I thought it made its point quite well: Wind energy availability is nearly exactly out of phase with the electrical load.

Clearly, the chart needs to use two axes (clearly labeled) with one shifted off the origin in order best to make its visual point (which is not that wind energy comes anywhere close to carrying the whole load at any time). Consider how the visualization would look if you forced both curves onto the same axis.
