Texas leads the nation in wind power, but some environmentalists worry about bird deaths cause by wind turbines – typically, birds fly into the blades of the turbines.

Now, a new approach pioneered by the U.S. Geological Survey and the U.S. Fish and Wildlife Service hopes to decrease those fatalities by trying to calculate the probability of bird-turbine collisions, while recognizing the inherent uncertainty of the phenomenon.

Standing on the shore of the Baltic sea a few miles outside of Copenhagen, Denmark, the view’s about what you’d expect. Rocky shore, grey horizon, a boat here or there. But this shore is special. Look up, and you’ll see — and hear — three giant offshore wind turbines cutting through the air. Each stands 500 feet tall, with three blades (each close to 200 feet long), spinning non-stop.

“The blades look quite thin, but don’t be cheated,” says Rune Birk Nielsen, with DONG Energy, which runs the turbines. “They each weigh about twenty tons. They are massive.” Each turbine has a capacity of 3.6 megawatts, or enough to power 3,000 Danish homes.

Public Utility Commission

From StateImpact Texas:

We’re all going to be paying for it, so you might be glad to know that a new set of transmission lines to bring wind power from the Panhandle and West Texas to folks in North and Central Texas appear to be off to a good start. According to a new federal analysis this week, the Competitive Renewable Energy Zones power transmission project, also known as CREZ, is already resulting in fewer curtailments of wind power and more even prices in Texas’ energy market.

The project cost $7 billion, a price that will be paid for by tacking on a fee to Texans’ utility bills. On average, your power bill could go up several dollars a month.

In the coming years, the federal government wants Texas to reduce its carbon emissions by about 40 percent. With a goal like that, you might expect to see more programs aimed at promoting renewable energy in Texas. But something like the opposite appears to be happening.

Donna Nelson, chair of Texas’ Public Utility Commission, asked last month if wind power generators, not Texas utility customers, should pay for upgrades to transmission lines. The Commission regulates the state’s electric grid, among other things.

By New Year's Day, the network of transmission lines that comprise Texas' "Competitive Renewable Energy Zone" [CREZ] will be fully operational, bringing electricity from wind turbines in West Texas and the Panhandle to points east. Many of the lines are already active (and have contributed to record-breaking percentages of Texas electricity coming from wind), but the Jan. 1 deadline is cause for celebration among those who have long prided Texas' role as a leader in wind power.

World Series

The Texas Rangers lost to the St. Louis Cardinals, 10-9 in 11 inning last night. The two are now tied in the World Series, 3-3. That forces a Game 7 of the World Series tonight in St. Louis. This is the first time in nine years that a World Series has gone gone to a seventh and deciding game.

Texas generated the most wind power in its history earlier this month, as more coastal wind farms come online. On October 7, the state generated 7,400 megawatts of wind power, according to the Electric Reliability Council of Texas (ERCOT).

Fifteen percent of all electricity on the ERCOT grid, which covers 85 percent of Texas, was coming from wind power on that day. The previous record, set in June, was 7,355 megawatts.

One of the great contradictions of Texas is that, while we are the largest emitter of greenhouse gas in the United States, we also generate far more wind power than any other state. Perhaps it’s no surprise then, to find a company pushing to build the largest offshore wind farm in the country is based right here in Austin.

Technically, any offshore wind farm would be the largest in the U.S. That's because none exist yet, even though many projects are in the works. But Austin-based Baryonyx Corporation, with an office in the Littlefield Building on E. 6th St., hopes to construct a 200 turbine wind farm off the Gulf Coast with enough capacity to power 750,000 homes.
