RENEWABLE ENERGY YOLO COUNTY COUNTY-WIDE SOLAR PROJECT Responding to recession-caused budget cuts and a desire to reduce its carbon footprint, Yolo County’s Board of Supervi- sors worked with SunPower, a leading global solar technol- ogy company, to develop, design and build solar photovoltaic ground mount systems that will produce 5.8 megawatts of electricity. The County-Wide Solar Project includes the 5-megawatt Grasslands system in Davis, California, and the 800-kilowatt Cottonwood solar system in Woodland. Both systems began generating power in July 2013. Yolo County’s communities have enjoyed economic, environmental and edu- cational benefi ts associated with this project, including utility bill savings and revenue generation, reduction of greenhouse gas emissions and the establishment of K-12 energy acad- emies. The academies educate students about environmental science, renewable energy technology and energy auditing. The project not only required zero capital investment from the County, it also eliminated its $1.4 million annual electric- ity bill. In addition, the solar systems generate $438,000 in annual revenue and produce 152 percent more electricity than County operations require. Some 12,000 metric tons of car- bon dioxide emissions are avoided each year in Yolo, equiva- lent to removing over 2,500 cars from California’s roads. This project serves as a model for other counties throughout California because it can be duplicated and implemented in a variety of ways.

COUNCIL OF GOVERNMENTS HERO PROGRAM


The HERO, or Home Energy Renovation Opportunity Pro- gram, was developed to provide fi nancing access to residen- tial and commercial property owners wanting to make energy effi ciency, renewable energy, or water conservation improve- ments to their properties.


The Western Riverside Council of Governments, representing 17 western Riverside cities and the County of Riverside, has implemented HERO, the nation’s largest Property Assessed Clean Energy – PACE – Program. It provides the fi nanc- ing for these effi ciency projects, which is then repaid by the property owner through property tax payments. HERO’s success in Western Riverside County has led to the develop- ment of California HERO to expand the program state-wide. So far, more than 7,000 residential projects in 82 cities across California have been completed, representing approximately $132 million in energy and water conservation retrofi ts. More than 6,000 additional projects, representing another $316 mil- lion, have been approved for fi nancing. The HERO Program is a ‘win-win’ for the environment and the economy, as it addresses a number of issues including a signifi cant reduction in energy and water use, which in turn lowers utility bills, a signifi cant reduction of greenhouse gases, and it provides a spark to the economy by creating and maintaining jobs for local area contractors.

WASTE MANAGEMENT ENCINA WASTEWATER AUTHORITY PUREGREEN The Encina Wastewater Authority currently produces 80 per- cent of its 2.2 megawatt annual electricity from biogas which is created during a wastewater treatment process that uses bacteria to decompose biological and chemical waste. The resulting sludge, a waste product, which was rich in nutrients, was shipped to Arizona, costing the Authority $2 million a year with signifi cant greenhouse gas emissions. In an innova- tive approach for a public agency, the Encina Wastewater Au- thority developed a marketing plan for a new product made from the sludge, “PureGreen” fertilizer pellets. Within 14 months from inception, in 2013, Encina exceeded its fi ve-year objectives, resulting in a 75 – 90 percent reduction in trans- portation and treatment of 100 percent of the residual solids generated. The results have been transformational for the organization. Now PureGreen pellets replace 100 of the 125 tons per day of sludge that were being shipped to Arizona. Their commitment to alternative fuels means that Encina will soon be a net-zero energy consumer, using resources embed- ded in the wastewater stream to achieve energy independence as key to sustainable water resources management. Over 3,000 tons of PureGreen Organic Nitrogen Fertilizer generat- ing nearly $250,000 in revenue have been sold during the fi rst 4 years of operations.


TRANSPORTATION CITY OF SANTA ANA GREEN FLEET STRATEGIC PLAN In 2013, the City of Santa Ana’s Facilities, Fleet and Central Stores Division developed a fi ve-year Green Fleet Stra- tegic Plan to save money, improve air quality and reduce dependency on fossil fuels. The plan focuses on the use of conventional fuel techniques and alternative-fueled vehicles to run an environmentally-friendly, fuel effi cient operation. The plan is already producing impressive and quantifi able results after its fi rst full year in operation. Two of the main objectives of the plan are to reduce the total number of fl eet vehicles and to replace existing conventional fuel vehicles with alternative-fueled vehicles. At the end of 2013, the de- partment had removed 299 vehicles, downsizing to 651 cars, trucks and pieces of equipment. By early 2014, 20 percent of the fl eet, or 125 vehicles were converted from running on conventional fuels to alternative energy sources. The success of the plan hinges on the melding of conventional techniques with emerging technologies. A strict Vehicle and Equipment Replacement Policy has given Santa Ana the opportunity to remove older heavy-duty trucks with new vehicles powered by alternative fuel or Tier 3 or 4 diesel engines. Within the next fi ve to seven years, the City is working to achieve a 75 to 80 percent alternative-fueled fl eet.
