[Paleopsych] Wind Power Falls Under $0.01/kwh

1 cent may have been a bit optimistic,
but I gather that a lot of turbines are
being put up because they are competitive
with gas. Bigger units mounted higher
are making the difference.
Wind is intermittent, but fine-grained
installations of other sources including
gas turbines, biodiesel, and pumped storage
can help handle the variations.
By fine-grained I mean having a number of
relatively small units that can be brought on
line quickly to handle the fluctuating load.
Right now a lot of energy is wasted providing
"spinning reserves" because the big plants
take a long time to come up.
If you have ever driven north from the airport
in San Francisco in the afternoon you
have driven through an area where every
afternoon a 30mph wind blows from
the ocean to the bay- just in time for the
peak usage hours.
Overall, I think the solution will be emergent
rather than dictated or legislated.
