Local irrigation districts thinking green

Gov. Schwarzenegger has ordered the state's electrical utilities to get 33 percent of their power from renewable sources by 2020.

Here's where the Modesto Irrigation District stands:

12 percent of its power is renewable, almost all of it from wind turbines in Solano County and Washington state.

The MID would reach 16 percent with an Oregon wind project expected to be running by late 2010.

The total could hit 21 percent in 2011, including the large solar energy system planned for North McHenry Avenue and expansion of part of the wind systems.

The renewable share could be 22 percent in 2015 thanks to another wind expansion.

The share could drop to 17 percent in 2017 because of an expiring wind contract. The MID is exploring other options for renewable power. Under the state mandate, they can be sources such as wind, solar, geothermal, biomass and small hydroelectric systems. Large hydro plants, such as the MID's on the Tuolumne River, do not count.

Other utilities

The Turlock Irrigation District gets 28 percent of its power from renewable sources, almost all of it from a wind system that started running in Washington state in May.

Pacific Gas & Electric Co. got 14 percent of its power from renewable sources in 2008. They included wind, geothermal, biomass and small hydro power.
