Solar

Solar Thermal uses solar energy both for heating and generating electricity. Solar thermal energy is free | dasolar.com
"Solar thermal technology comprises three different methods to convert solar energy for use. The first method collects the energy of the sun to heat water or air for direct use in solar home heating. The second method is used by large power utilities to indirectly create electricity through concentrated solar heat energy. The third method, known as passive solar, leverages energy efficiency and the design of a building to regulate the amount of solar energy it receives in order to regulate it's temperature."
