In a continuing effort to reduce the city's carbon emissions -- while boosting the smugness of Prius owners, of course -- Mayor Ed Lee's office will announce the availability of free power for electric for cars in San Francisco and SFO. The no-cost charges will last until the end of 2013. Who's paying for this, you ask? Well, according to the Examiner: "The $300,000 bill for the new program is being footed by a combination of federal, state and local grants, including one from the Bay Area Air Quality Management District." Electric-car charging station locations will be as follows:

- Civic Center garage
- Ellis O’Farrell garage
- Fifth & Mission garage
- General Hospital garage
- Golden Gateway garage
- Japan Center garage
- Lombard garage
- Mission Bartlett garage
- Moscone Center garage
- North Beach garage
- Performing Arts garage
- Pierce Lombard garage
- Polk Bush garage
- Portsmouth Square garage
- SFO garages
- St. Mary’s Square garage
- 1600 Mission Street garage
- Stockton Sutter garage
- Union Square garage
- Vallejo Street garage

Lee will make the official announcement later today. To learn more, check out the Examiner's piece on free vehicular electricity.
