Beware the Duck of Doom | Center For Global Development

A recent post by Steve Weissman of Berkeley Law on Legal Planet, an environmental law and policy blog, highlights a chart that looks like a duck. The duck chart was produced by the California Independent System Operator, the organization in charge of managing the state's power grid. Weissman calls it the "Duck of Doom" -- with good reason.

The numbers along the horizontal axis are the hours of the day. The fattening body of the duck shows the addition of more and more wind and solar power (WSP) over the coming years. More WSP is a good thing. But as the chart makes clear most of this will be available during the daylight hours, with very little during the peak usage period from around sundown to midnight.
