The sun gives us the power to generate electricity, keep your shower hot, and heat, cool and light your home in a way that is clean, safe, and sustainable. Solar energy – radiant energy from the sun – is one of the cornerstones of the City’s plan to achieve a 100% renewable electricity supply, and reduce our reliance on fossil fuels for heating.
Wind energy is an excellent and abundant renewable resource. The same winds that rustles leaves and turn umbrellas inside out can be harnessed to spin turbines and produce electricity. Learn about the wind resources in and around San Francisco, how wind turbines work, and what role wind energy can play in helping San Francisco achieve its renewable energy goals.
Hydropower is the use of water to power machinery or make electricity. Anyone who has listened to the rushing streams of the Sierra Nevada mountains or stood in the surf of the Pacific Ocean knows the power of moving water.
Geothermal energy is the heat from the Earth. This heat can come from molten rock (“magma”) deep inside the earth, or very hot rock and ground water a few miles below the Earth’s surface, and can be used for direct heating or to produce electricity through a steam turbine.
