Sources of energy that can only be used once and must be replaced to meet demand.
Sources of energy that can be reused.
Renewable energy sources that, no matter how much we use them, can not be overused.
Sources of energy that have the capacity to be renewable, but only if used properly.
The act of actively limiting energy use.
tiered rate system
An incentive program that some electric companies use that promotes minimized electrical use.
The most amount of energy used by consumers at a given time.
passive solar design
A means of saving energy by having overhangs block out sunlight in the summer and let it in the winter, in addition to using materials with high thermal inertia.
A material's capacity for retention of heat or cold.
A liquid form of biomass, generally as ethanol or biodiesel, that can be used for combustion.
Carbon molecules that are being reentered into the atmosphere from biomass that were recently there.
Carbon molecules that are being reentered into the atmosphere from fossil fuels that have been trapped underground for millions of years.
The condition that when biomass is burned, the net amount of carbon changing in the atmosphere is zero.
The act of cutting down more trees in a forest than are being replanted.
A corn or sugarcane-based biofuel that can be used in conjunction with gasoline, generally consisting of 85% of the mix.
A plant-based biofuel that can be used in conjunction with petroleum diesel, generally consisting of 20% of the mix.
Cars that are able to operate with normal gasoline, or with E-85.
Electrical energy gained from using kinetic energy in water to spin turbines.
A means of producing hydroelectricity that uses very small dams, and then having the water go through channels.
A means of producing hydroelectricity by building a massive dam and creating a reservoir. The water goes through turbines at the bottom of the dam.
Kinetic energy in water that is caused by waves and such movement.
A form of sedimentation that occurs at the bottom of reservoirs.
active solar energy
Technological means of acquiring solar energy.
photovoltaic solar cells
A panel that uses semiconducting materials to convert solar radiation into electricity.
concentrating solar thermal (CST)
A system that has many reflectors point solar radiation at a specific point, which heats water to generate electricity.
Heat energy from within the Earth that is produced by the decay of radioactive elements.
ground source heat pumps
Systems similar to geothermal energy extraction, but use the thermal inertia of soil to heat water.
Energy that comes from the unequal heating of the atmosphere, that creates air currents.
The device used to capture wind energy that functions similar to that of any other means of electrical generation, but it is much larger.
A device that is similar to a battery, but instead reacts hydrogen with oxygen, to produce energy and water.
A means of separating hydrogen and oxygen for use in a fuel cell by running an electrical current through water.
A theory for electrical grids that use the internet to self-regulate the needs of consumers to be maximally efficient.
