The Town of Yountville has converted approximately 70% of its streetlights to energy efficient LED fixtures and is working with PG&E to convert the remaining streetlights. The town requires all new streetlight and park lighting installations to be LED lighting. The town also recently implemented HVAC and lighting improvements, including occupancy sensors at the Town Hall and Community Center, and insulated the Public Works building. At its Wastewater Treatment Plant, the town modified aeration blowers and replaced a water heater and six motors with energy-efficient models. These improvements save the town over 100,000 kWh of electricity and nearly 500 therms of natural gas each year.
