San Jose, California's third-largest city, also plans to go all-renewable by 2022, according to the California-based Renewables 100 Policy Institute, which helps promote renewable energy transition projects.
Other major U.S. cities that have even more ambitious goals than San Diego include Cincinnati, Ohio; Grand Rapids, Mich.; Hillsboro, N.C.; San Francisco, and Santa Cruz, and Lancaster, Calif, according to the institute. Both San Francisco and Lancaster plan to reach their 100% renewable energy goal by 2020.
Along with renewable energy, San Diego plans to increase the number of zero emissions vehicles in the municipal fleet to 50% by 2020 and 90% by 2035.
But even as major U.S. cities are committing to renewable energy, only a small percentage of the nation has gone green.
As of 2014, only about 11% of electricity in the U.S. is supplied by renewable sources, such as wind, solar and hydroelectric, according to the U.S. Energy Information Administration (EIA). Another 9% comes from nuclear power plants. By 2040, the EIA projects only 15% of U.S. power will come from renewable sources.
The rest of the power consumed in the U.S. comes from natural gas (31%), petroleum (26%) and coal-fired generators (24%), the EIA stated.
