Term
energy
Definition
the ability to do work or cause a change.
Term
kinetic energy
Definition
the energy produced by motion.
Term
potential energy
Definition
the energy that an object has because of its position or shape.
Term
combustion
Definition
burning; the chemical reaction when fuel combines rapidly with oxygen.
Term
energy efficiency
Definition
an expression of how much of the energy put into a system actually does useful work.
Term
renewable energy
Definition
an energy resource that is readily available or that can be replaced in a relatively short time; includes wind, moving water, the sun's heat, and wood.
Term
nonrenewable energy
Definition
an energy resource that cannot be replaced in a relatively short time; includes fossil fuels and nuclear energy.
Term
electricity
Definition
the energy produced by the flow and interaction of electrons.
Term
strip mining
Definition
a type of mining in which layers of surface soil and rock are removed from large areas to expose the resource.
Term
subsurface mining
Definition
a type of mining in which vertical shafts are dug deep into the ground and networks of horizontal tunnels are dug or blasted out to follow deposits of a resource.
Term
petroleum
Definition
a liquid fossil fuel made up mostly of hydrocarbons; the primary source of gasoline.
Term
petrochemical
Definition
a chemical compound derived from oil that is used to make plastics, detergents, and other products.
Term
oil sands
Definition
a deposit of moist sand and clay that can be mined to extract bitumen, an oil-rich hydrocarbon.
Term
oil shale
Definition
rock that contains hydrocarbons; can be burned directly or processed to extract liquid petroleum.
Term
methane hydrate
Definition
an ice-like solid that consists of molecules of methane within a crystal network of water molecules; can be burned to release energy.
Term
acid drainage
Definition
the sulfuric acid produced when sulfide minerals in exposed rock surfaces react with oxygen and rainwater to produce sulfuric acid.
Term
energy conservation
Definition
reducing energy use to prolong the supply of fossil fuels.
Term
nuclear energy
Definition
the energy that holds protons and neutrons together in the nucleus of an atom.
Term
nuclear fission
Definition
the conversion of the energy within an atom's nucleus to usable thermal energy by splitting apart atomic nuclei.
Term
nuclear reactor
Definition
a facility within a nuclear power plant that generates electricity through controlled nuclear fission.
Term
meltdown
Definition
the accidental melting of the uranium fuel rods inside the core of a nuclear reactor, causing the release of radiation.
Term
nuclear waste
Definition
the radioactive material left over from the production of energy and other processes in a nuclear power plant.
Term
nuclear fusion
Definition
the conversion of the energy within an atom's nucleus to usable thermal energy by forcing together the small nuclei of lightweight elements under high temperature and pressure.
