Energy Efficiency

California has led the nation in energy efficiency programs since the 1970s. Due to the state’s efficiency programs, per capita energy use has remained flat, while the rest of the US has increased by about 33 percent.

The CPUC regulates ratepayer-funded energy efficiency programs. The CPUC works with the investor-owned utilities, other program administrators, and vendors to develop programs and measures to transform technology markets within California using ratepayer funds.

Events, Meetings, and Workshops

The Energy Division will be hosting a public workshop on Water-Energy marginal water supply and avoided costs on April 25. The purpose of this workshop will be to present a staff proposal on marginal supply and preview the avoided cost calculations methodology and tools. This workshop follows up on the project work discussed at the January 30, 2014 workshop. Those wishing to gain more familiarity with this work are encouraged to review materials from the earlier workshops. The material can be found at:
