biomass
The total mass of all living matter in a specific area
renewable
In energy management, an energy source that is either potentially renewable or nondepletable
energy conservation
The implementation of methods to use less energy
tiered rate
A billing system used by some electric companies in which customers pay higher rates as their use goes up
energy efficiency
The ratio of the amount of work done to the total amount of energy introduced to the system
peak demand
The greatest quantity of energy used at any one time
passive solar energy
A method of converting solar energy into heat without pumps or fans (passive solar design- construction designed to take advantage of solar radiation without active technology)
thermal inertia
The ability of a material to maintain its temperature
modern carbon
Carbon in biomass that was recently in the atmosphere
fossil carbon
Carbon in fossil fuels
carbon neutral
An activity that does not change atmospheric CO2 concentrations
net removal
The process of removing more than is replaced by growth, typically used when referring to carbon
biofuels
Liquid fuels created from processed or refined biomass
ethanol
Alcohol made by converting starches and sugars from plant material into alcohol and CO2
biodiesel
A diesel substitute produced by extracting and chemically altering oil from plants
flex-fuel vehicles
A vehicle that runs on either gasoline or ethanol
hydroelectricity
electricity generated by the kinetic energy of moving water
run-of-the-river
Hydroelectricity generation in which water is diverted from a river to a generator and back to the river using the elevation change of the landscape.
water impoundment
The storage of water in a reservoir behind a dam
tidal energy
Energy that comes from the movement of water driven by the gravitational pull of the Moon
siltation
The accumulation of sediments, primarily silt, on the bottom of a reservoir
active solar energy
Energy captured from sunlight with intermediate technologies (pumps or photovoltaic cell)
photovoltaic solar cells
A system of capturing energy from sunlight and converting it directly into electricity
geothermal energy
Heat energy that comes from the natural radioactive decay of elements deep within Earth
ground source heat pumps
A technology that transfers heat from the ground to a building
wind energy
Energy generated from the kinetic energy of moving air
wind turbine
A turbine that converts wind energy into electricity
hydrogen fuel cell
An electrical-chemical device that converts fuel, such as hydrogen, into an electrical current
electrolysis
The application of an electric current to water molecules to split them into hydrogen and oxygen
smart grid
An effcient, self-regulating electricity distribution network that accepts any source of electricity and distributes it effectively to end users
