2. What is it?
Renewable energy is derived from sun, wind, water, or the Earth's core.
It also can be derived from biomass—or plant matter—which is grown,
harvested, and transferred into energy by one of a number of processes.
Renewable technologies are designed to capture and store this energy

3. •Photovoltaic solar panels convert sunlight directly into electricity.
•Wind turbines capture wind to turn rotors, which turns a generator and
creates electricity.
•Transpired solar collectors use sunlight to preheat air for heating purposes.
•Solar hot water heaters use the sun to heat water for domestic applications.
•Small-scale hydroelectric power plants flow water over turbines, which turn
a generator and create electricity.
•Fuel cells combine hydrogen and oxygen to produce electricity and heat.
•Ground source heat pumps transfer heat to the ground in summer and
extract heat from the ground in winter.
•Green power is electricity generated from renewable sources such as wind,
geothermal, biomass, and landfill gas.
Examples

4. To promote energy efficiency and environmentally sensitive energy generation, EPA
facilities are using renewable energy technologies to supplement or replace a large
portion of their energy requirements at the following facilities:
•Ada, Oklahoma (geothermal heat pump)
•Ann Arbor, Michigan (fuel cell)
•Chicago, Illinois, Regional Office (photovoltaic array)
•Corvallis, Oregon (photovoltaic array)
•Edison, New Jersey (solar water heating)
•Gulf Breeze, Florida (solar lighting)
•Golden, Colorado (wind power and transpired solar collector)
•Manchester, Washington (wind power)
•Research Triangle Park, North Carolina (photovoltaic solar panels and street lights)
