windy concerns
Taking a brief breather from Obamanausea, here is a little something on something big.
In this post Drew Thornley of the Texas Public Policy Foundation highlights the research and documentation I wish I could do.
The greatest impediment to wind's large-scale contribution to our energy supply is its intermittent nature. The wind must blow in order for wind turbines to produce power -- peak capacity comes when the wind blows at about 31 miles per hour. But because those conditions are rare, wind turbines typically produce only around 30 percent of their installed capacity over time. As in many other places, the wind in Texas blows least when we need it the most. The Electric Reliability Council of Texas (ERCOT) relies on a mere 8.7 percent of wind power's installed capacity when determining available power during peak summer hours.
Eight point seven percent. So if your local ex-oilman installs his 110 wind turbines, the state counts 10. That actually seems generous on stiflingly hot, still, summer day. I have to crank up all the nat gas generation we have just to run everyone's AC. Wind energy, for all of its "coolness" makes little sense.
Drew Thorley has the job I wish I did. Go read his whole report. Good stuff.
Now back to all Nobama, all Nobiden, all the time.

Dan, good catch! Yes, you're right that the most coommn turbine design used today (and throughout history) is the horizontal axis design. Thanks for correction!
