City Energy Accomplishments
- The U.S. Environmental Protection Agency's (U.S. EPA) "Top 25 Green Power Partner" list ranks the City of San Diego as the nation's top municipality in producing and using environmentally preferable "green power," which is electricity produced from renewable energy resources. The City of San Diego produces 153,000 MWh annually of electricity, equivalent to powering 14,194 homes. The electricity is produced from renewable sources such as methane gas harvested from the City Miramar Landfill, from treated wastewater that drives a hydro generator, and from photovoltaics placed on eleven city buildings. The City of San Diego consumes 65,400 MWh of this "green power" and the remainder is sold to the public utility.
- The City's Energy program saved 24 million kilowatt-hours and $3.5 million annually since 2001. As part of its program, San Diego requires that all municipal construction meet Leadership in Energy and Environmental Design (LEED Silver standards. In 2005, the city renovated its police headquarters making it virtually energy independent. The building uses multiple-speed fans, window tinting, and an energy management system. Cogeneration and photovoltaics provide much of the facility's electrical, heating, and cooling needs.
