A term generally applied to individual solar collectors, and typically to solar photovoltaic collectors or modules.

This device can automatically turn the heater off at night and on in the morning.

A characteristic applied to domestic water heaters that is the amount of gallons raised 100 degrees Fahrenheit per hour (or minute) under a specified thermal efficiency.

Power generation equipment or system capacity to meet peak power demands.

To allow or augment the natural movement of cooler air from exterior, shaded areas of a building through or around a building.

The conversion of heat into electricity by the use of thermocouples.

A hydrogen production process that process uses algae. Under certain conditions, the pigments in certain types of algae absorb solar energy. An enzyme in the cell acts as a catalyst to split water molecules. Some of the bacteria produces hydrogen after th ...

This committee has jurisdiction on the oversight and legislative responsibilities for: coal, nuclear, and non-nuclear energy commercialization projects; DOE National Laboratories; global climate change; new technologies research and development; commercia ...

Energy that comes from splitting atoms of radioactive materials, such as uranium, and which produces radioactive wastes.

The process of converting materials that are no longer useful as designed or intended into a new product.

Energy conversion technologies that harness the energy in tides, waves, and thermal gradients in the oceans.

A safety device consisting of a short length of relatively fine wire, mounted in a holder or contained in a cartridge and connected as part of an electrical circuit. If the circuit source current exceeds a predetermined value, the fuse wire melts (i.e. th ...

An electrical generator that runs at a constant speed and draws its excitation from a power source external or independent of the load or transmission network it is supplying.

The process of moving existing loads to off-peak periods.

A horizontal axis wind turbine in which the rotor is downwind of the tower.

A method of depositing thin semiconductor films used to make certain types of solar photovoltaic devices. With this method, a substrate is exposed to one or more vaporized compounds, one or more of which contain desirable constituents. A chemical reaction ...

The direction, at any point on the earth that is geographically in the northern hemisphere, facing toward the South Pole of the earth. Essentially a line extending from the point on the horizon to the highest point that the sun reaches on any day (solar n ...

Air that is returned from a heated or cooled space, reconditioned and/or cleaned, and returned to the space.

A type of incandescent lamp that contains a halogen gas in the bulb, which reduces the filament evaporation rate increasing the lamp life. The high operating temperature and need for special fixtures limits their use to commercial applications and for use ...

The component of a central receiver solar thermal system where reflected solar energy is absorbed and converted to thermal energy.
