L.A. hits 20% renewable energy goal by 2010, but is it sustainable?

Los Angeles mayor Antonio Villaraigosa announced this morning that the city has met its goal of providing 20 percent of the city's power from renewable sources in 2010. That's largely due to the municipally owned Pine Tree Wind Power Plant in the Tehachapi Mountains, which the Department of Water and Power opened in 2009 and which by the end of 2010 accounted for half of the utility's renewable energy. How did the city account for the other half? And how did Los Angeles manage to reach 20% without granting the DWP the rate increase it said it required last year to meet this goal? Patt checks in for a breakdown of the numbers and an update on whether Los Angeles is on track to meet its next goal of providing all of the city's power from renewable resources by 2020.
