Aspen, Colorado (United States)
Today, the City of Aspen electric system uses 100% renewable energy (46% hydroelectric, 53% wind power, 1% landfill gas). By showing the economic viability of renewable energy integration, we hope this model will be adapted worldwide.
Freiburg, Baden-Württemberg (Germany)
Freiburg promotes itself as a Green city—especially in the areas of transportation, energy, waste management, land conservation, and green economics—and the city has won various national and international environmental awards. Actually, in some respects (e.g., waste management), Freiburg is much like other German cities. But in the areas of energy and green economics, it is particularly outstanding.
San Diego, California (United States)
All things being equal, a PV installation in San Diego will deliver more solar power output than a comparable installation in most other parts of the country. This also means that San Diego residents who install solar enjoy lower monthly electricity bills and faster payback periods than their counterparts in New York, Chicago, or San Francisco.
Unified Port of San Diego
The San Diego Board of Port Commissioners has approved an "Energy Road Map" that will be used to outline the sustainable energy partnership between the Port and San Diego Gas & Electric. The goals of the Partnership are to identify opportunities to deliver net energy savings, peak demand savings and greenhouse gas reductions through implementation of energy efficiency activities in Port operations.
