Texas is cleaner, according to pending study

The City of Houston, the Houston Advanced Research Center and Environment Texas will release a new analysis of government data of carbon dioxide in Texas and the U.S. from 1990 to 2007 later this week.
One expected finding: CO2 pollution in Texas went down by 2 percent between 2004 and 2007.
The cause? The leadership of Texas and Houston in producing and buying wind energy. The City of Houston gets about 25 percent of its power for municipal buildings from wind power, and the state of Texas leads the nation and much of the world in wind-generated electricity.
A press conference announcing the findings is set for 11 a.m. this Thursday at Tranquility Park downtown, facing City Hall, Smith Street between Walker and McKinney Streets.
While every little bit helps, the 2 percent improvement doesn’t usually seem like the kind of thing folks hold press conferences over, so I’m sure there will be more to it.
