Every building needs electricity and other kinds of energy or power in order to be useful. Energy is what allows us to turn on the lights, use a computer, or bake chocolate chip cookies. Green buildings are smart about the way they use and conserve or save energy. There are many clean sources of energy that don't pollute our environment the way burning fossil fuels like oil, coal and gas do. These alternative or different sources of energy come from the sun as solar power, the wind as wind power, and the ocean tides as tidal power. Green buildings often have solar panels on their rooftops. Some of these panels collect energy from the sun and use it to make electricity for use in the building. Other solar panels directly heat water that can be used to wash clothes or heat radiators to keep us warm. Learn more about solar energy and other alternative energy
