passive solar heating
|
a system of putting the sun's energy to use without requiring mechanical devices to distribute the heat
|
|
active solar heating
|
a system of putting the sun's energy to use in which a series of collectors absorb the solar energy and pumps or fans distribute the collected heat
|
|
solar thermal electric generation
|
a means of producing electricity in which the sun's energy is concentrated by mirrors or lenses onto a fluid-filled pipe; the heated fluid is used to generate electricity
|
|
Photovoltaic solar cell
|
a wafe or thin filmm of solid state materials, such as silicon or gallium arsenide, that are treated with certain metals so that they generate electricity when solar energy is absorbed
|
|
fuel cell
|
a device that directly converts chemical energy into electricity without the intermediate step of needing to produce steam and use a turbine and generator; the fuel cell requires hydrogen and oxygen from the air
|
|
biomass
|
plant and animal material used as fuel
|
|
wind energy
|
electic energy obtained from surface air currents caused by the solar warming of air
|
|
hydropower
|
a form of renewable energy that relies on flowing or falling water to generate electricity
|
|
tidal energy
|
a form of renewable energy that relies on the ebb and flow of the tides to generate electricity
|
|
geothermal energy
|
the use of energy from earth's interior or either space heating or generation of electricity
|
|
energy conservation
|
using less energy
|
|
energy efficiency
|
using less energy to accomplish a given task
|
|
cogeneration
|
an energy technology that involves recycling waste heat
