Finding and implementing ways to use energy.
Tiered rate system
A billing system used by some electric companies in which customers pay higher rates as their use go up.
The greatest quantity of energy used at any one time.
Passive solar design
Construction designed to take advantage of solar radiation without active technology.
A property of a building material that allows it to maintain heat or cold.
An energy source that can be regenerated indefinitely as long as it is not overharvested.
An energy source that cannot be used up.
In energy management, an energy source that is either potentially renewable or nondepletable.
Liquid fuel created from processed or refined biomass.
Carbon in biomass that was recently in the atmosphere.
Carbon in fossil fuels.
An activity that does not change atmospheric CO2 concentration.
The process of removing more that is replace by growth, typically used when referring to carbon.
Alcohol made by converting starches and sugars from plant material into alcohol and CO2.
A diesel substitute produced by extracting and chemically altering oil from plants.
A vehicle that runs on either gasoline or gasoline/ethanol mixture.
Electricity generated by the kinetic energy of moving water.
Hydroelectricity generation in which water is retained behind a low dam or no dam.
The storage of water in a reservoir behind a dam.
Energy that comes from the movement of water driven by the gravitational pull of the Moon.
The accumulation of sediments, primarily silt, on the bottom of a reservoir.
Active solar energy
Energy captured from sunlight with advanced technologies.
Photovoltaic solar cell
A system of capturing energy from sunlight and converting it directly into electricity.
Energy generated from the kinetic energy of moving air.
A turbine that converts wind energy into electricity.
Heat energy that comes from the natural radioactive decay of elements deep within Earth.
Ground source heat pump
A technology that transfers heat from the ground to a building.
An electrical-chemical device that converts fuel, such as hydrogen, into an electrical current.
The application of an electric current to water molecules to split them into hydrogen and oxygen.
An efficient, self-regulating electricity distribution network that accepts any source of electricity and distributes it automatically to end users.
