Try our free Energy-Saving Toolkit

Check out a Do-It-Yourself (DIY) Home Energy-Saving Kit from the Sunnyvale Public Library, Columbia Neighborhood Center (785 Morse Ave), or Sunnyvale Environmental Services (505 W. Olive Ave, Suite 130). It’s stocked with supplies and devices that can help you lower your utility bills and energy use. You get to keep free items from the Kit, such as four compact fluorescent light bulbs, three faucet aerators, a low-flow showerhead, outlet gaskets, weather stripping and water leak detection tablets.

Devices that enable the measurement of energy and water use (to be returned to the Library with the Kit) include:

  • A Kill-A-Watt® Meter for measuring the energy use of appliances and equipment.
  • A thermal detector that checks for heat loss through windows, vents and doors.
  • A special thermometer that helps set refrigerators and freezers to appropriate temperatures.
  • A water flow rate bag that measures the true rate of flow from faucets and showerheads.

    How Your Energy-Saving Efforts Can Help Sunnyvale win $5 Million

    Sunnyvale could win up to $5 million for future energy-saving programs if the community can reduce its overall electricity and natural gas usage by December 2016.

    Sunnyvale is one of 50 cities and counties nationwide competing as a semi-finalist in the Georgetown University Energy Prize competition created to motivate communities with populations between 5,000 and 250,000 to reduce their energy use in an innovative and scalable way. The community that does the best job reducing overall energy over a two-year period (Jan. 1, 2015 to Dec. 31, 2016) will win the prize. Other local cities competing include Palo Alto, San Mateo, Fremont, Davis and Berkeley.If Sunnyvale wins the competition, the prize money would help further energy efficiency initiatives already identified in the city’s Climate Action Plan.

    How is Success Measured?

    Sunnyvale will be rated on how much we can reduce our residential and municipal energy consumption during the semi-final phase through Dec. 31, 2016.If we are selected as one of the top 10 finalists, our community will be evaluated based on: net energy savings achieved; effectiveness of our education efforts; and innovation, accessibility and quality of our energy-saving programs, including the potential for replicating them at a larger scale.

    What Can I Do to Help Win the Prize?

    Small changes can make a big difference for the competition. Try these five simple actions:

    • Turn off lights when not needed.
    • Change incandescent light bulbs to energy-saving lights (CFLs or LEDs).
    • Install smart power strips to reduce electricity drawn by appliances when not in use.
    • Fix defective plumbing or install water-efficient fixtures.
    • Turn your thermostat setting to cool/heat only when needed, or install a programmable thermostat.
