While you were busy watching Vladimir Guerrero take home the Home Run Derby crown two nights ago (not to mention the All-Star game last night), you may not have been aware that AT&T Park was feeding uber-clean energy back into the grid serving PG&E's customers throughout northern and central California. Sure enough, the home of the San Francisco Giants is now also home to 590 Sharp solar panels located in three separate areas of the stadium, which combine to generate some 120-kilowatts of electricity. The size of the entire array is reportedly "equivalent to approximately 40 residential solar systems," and while this system won't conjure up as much power as the CIS Solar Tower, it will certainly make good use of the ballpark during the off-season.
