Default New Wind Farms Cheaper Than Even Existing Coal Plants

What do you do? Sit around and stew, the explode into meaningless rambles?

Cost (installed) per watt, commercial scale:

Solar: $2.30
Wind: $1.63
Natural Gas: $0.89
Nuclear: $5.00 - $8.00
Coal: $5.30 ("Clean" technology)

On reliability (Add emphasis is mine):

Reliability of wind turbines has improved with time and has achieved an availability of--- 98%,--- but wind turbines fail at least once per year, on average, with larger wind turbines failing relatively more frequently. A recent study of US wind turbines found that when all sources of downtime are accounted for, the average wind turbine actively generates power for 1.5 days between downtime events and that the average downtime is 1.6 hours.

Point being that a wind "farm" does not rely on a single turbine, but multiples, often many dozens of turbines. So, a single reactor event may take a nuclear plant down for a month, or a single turbine issue may take a coal or gas plant down for a week. But a single wind turbine event, for even two days, is hardly a blip on the radar.
