Nearly four decades after President Carter adventurously installed solar panels on the White House, America’s energy transition away from fossil fuels has seen only modest progress. 2007 marked the first year in history when more than half of the world’s population lived in cities, and the U.N. estimated that, by 2030, urban settings will be home to nearly two thirds of the global population. However, it was just in March 2017 that monthly electricity generation from wind and solar exceeded 10% of total U.S. electricity generation for the first time. As America’s vibrant cities grow at an unprecedented pace, so does the importance of sustainable urban planning, power generation, transport systems, water and sanitation, and waste management. We set out to gauge how U.S. cities fare in terms of sustainability, and how the commercial real estate industry has embraced green building to support these efforts. We ended up with a ranking of 40 ‘sustainably powered’ U.S. cities. Read on to see how we did it and what the results show. Methodology: Our Scores, Explained For the purpose of this study, we looked at data on U.S. cities with a 100,000 population minimum, and present the 40 that achieved top scores: Arlington, Va.; Atlanta, Ga.; Austin, Texas; Baltimore, Md.; Boston, Mass.; Boulder, Colo.; Chicago, Il.; Cleveland, Ohio; Columbus, Ohio; Dallas, Texas; Denver, Colo.; Detroit, Mich.; Durham, N.C.; Eugene, Ore.; Hayward, Calif.; Houston, Texas; Indianapolis, Ind.; Knoxville, Tenn.; Lakewood, Colo.; Lancaster, PA; Las Vegas, NV; Los Angeles, CA; Minneapolis, MN; New York, NY; Oakland, CA; Philadelphia, PA; Phoenix, AZ; Pittsburgh, PA; Portland, OR; Reno, NV; Richmond, VA; San Antonio, TX; San Diego, CA; San Francisco, CA; Savannah, GA; Seattle, WA; St. Louis, MO; Tucson, AZ; Washington, D.C.; Yonkers, NY. The starting point of our research was to learn how each of...
