Each year the research firm Clean Edge releases their annual U.S. Clean Tech Leadership Index which tracks the sustainable clean tech progress of the 50 largest metro areas and the 50 states. This year’s report highlighted gains made in 2014. One of the features of the report is a focus on cities that have the most green buildings. This year’s top spot went to Washington, D.C., driven by efficiency efforts in federal buildings. Boston and Minneapolis also made the top ten. Otherwise cities that made the top ten list include San Francisco, Denver, Portland, Seattle, San Diego, Sacramento. Atlanta became the first southern city to make the top ten list. The five cities at the bottom of the green building list were: New Orleans, St. Louis, Memphis, Birmingham and Oklahoma City.
Other significant findings from this year’s report are:
▪ Colorado, Vermont, Oregon, and Washington each now exceed 100 LEED projects per million people for the first time
▪ Eleven states now generate more than 10 percent of their electricity from non-hydro renewable energy sources, with two — Iowa and South Dakota — exceeding 25 percent.
▪ U.S. solar installations climbed more than 40 percent year-over-year
▪ Registrations of all-electric vehicles more than doubled from last year to nearly 220,000 nationwide
▪ At least eight states now have more than 50 percent smart-meter market penetration; California leads with 70 percent.
