Past wind farm deployments and advances in the wind energy sector have worked to open up new areas primed for future deployment. As tower heights rise from 50 meters to 80 meters above the ground, turbine can capture more wind captured at one time (higher wind speeds are usually present away from the ground) as well as during more parts of the day.
The result is that instead of 7.4-8.4 m/s wind speeds, new turbines can capture 8.5-10 m/s winds (see map below (gif source & pdf). This translates to a 1.2 cent reduction per kilowatt-hour of wind energy: 10.8 cents, down from 12.0 cents. My utility currently charges 4.6 cents per kilowatt-hour of energy. The utility's energy mix as of 2010 was: 61.31% coal, 26.88% natural gas, 10.26% wind, ~1% rest). They are also filing for a 5.99% increase in electricity charges.

President Barack Obama announced his off-shore oil drilling plan today. Count me among the folks who are pretty frustrated with the announcement and its details. I'll start with what the announcement included, then get into why I think it's a bad set of proposals.
Atlantic coast drilling would be open for exploration from Delaware to mid-Florida. Gulf of Mexico exploration would be open off the south and west coasts of Florida. The Chukchi and Beaufort Sea areas off the north coast of Alaska would be opened. For now, the West Coast remains off-limits. Additionally, the Department of Agriculture will work with the Pentagon to use more biofuels in military vehicles. Thousands of hybrid vehicles will also be purchased for the federal motor pool.
This decision marks a reversal of off-shore drilling policies that Obama campaigned on in 2008. To secure the Democratic Party nomination and win the general election, Obama distinguished himself from the Bush Regime and Sen. McCain. Now, "compromise" and "bipartisanship" appear to demand something else entirely.
