Valley Climate Action Center

cacThe Valley Climate Action Center is an outgrowth of the successful Yolo County Energy Efficiency Project (YEEP) which operated in 2004 and 2005. Yolo County, along with its partner cities, was awarded a $3.2 million grant from the California Public Utilities Commission. Its program was a hybrid of hardware giveaways, direct installation, rebates, and public education. By specializing in the most cost effective measures – such as compact fluorescent light bulbs, sun shades, and free advice – YEEP saved over seven million kilowatt hours of electricity and 1500 kilowatts of demand for utility power. The energy savings translated into about $16 million of savings on the 15-year lifetime of the energy measures.
info-carbon-3YEEP was organized as a non-profit corporation in partnership with the City of Davis. That partnership continues today as YEEP takes a new name, the Valley Climate Action Center (VCAC), and broadens its focus to include measures which reduce carbon emissions of energy and water use, buildings and transportation, Davis and beyond. This concept grew out of the work of the city’s Climate Action Team (CAT) and its recommendations for reducing the city’s carbon footprint.

YEEP showed that if people are informed and effectively helped they will choose efficiency, for both practical money-saving reasons and as a social duty. VCAC wants to go farther and provide a one-stop shop the help residents and businesses make sensible investments in low-carbon energy and efficiency. This means drawing on 40 years of marketplace experience in which alternative and efficiency investments have been hampered by barriers such as high first cost, lack of attractive financing, and lack of information on the best products, technologies, and providers.
