Energy Efficiency & Renewable Energy

How we generate and how we use electricity are equally important. When our buildings are more efficient, we need to produce less energy. The less energy we need, the less we use, and the better it is for the environment. Transforming buildings to be more energy efficient can play a major role in reducing the impact of climate change. San Mateo County and the Office of Sustainability offer a range of tools, assistance programs and resources to help everyone in the County work together to use energy wisely and reduce our climate impact.

San Mateo County Energy Watch
