On April 12, Gov. Jerry Brown signed into law the highest renewable portfolio standard in the country. Senate Bill X1 2 requires that 33 percent of energy sold in California come from renewable resources in 2020. Resources that qualify as renewable include energy generated from solar, wind, small hydro and biomass facilities. Renewable requirements such as these are common throughout the country. In fact, the majority of states have enacted similar, although not as stringent, renewable portfolio standards (RPS). Congress has also attempted to follow suit by proposing several different versions of RPS legislation, but thus far has been unable to pass a national requirement. This new law will not result in a major shift in California's energy requirements. Renewable requirements similar to the new RPS law are already being implemented in California. Rather, the passage of SB X1 2 is likely to result in a re-examination of current requirements and an evaluation of how to effectively procure renewable resources and integrate them into the grid.
