Glossary of Terms Energy – the ability to do work or the ability to move an object. Electrical energy is usually measured in kilowatthours (kWh), while heat energy is usually measured in British thermal units (Btu). Potential energy – stored energy and the energy of position. Kinetic energy – the energy of a body which results from its motion. Chemical energy – energy stored in a substance and released during a chemical reaction such as burning wood, coal, or oil. Mechanical energy – the energy of motion used to perform work. Nuclear energy – energy that comes from splitting atoms of radioactive materials, such as uranium. Gravitational energy (Gravity) – the natural force of attraction of the mass of a heavenly body (as the earth) for bodies at or near its surface. Radiant (light) energy – any form of energy radiating from a source in waves. Thermal (heat) energy – the total potential and kinetic energy associated with the random motions of the molecules of a material. Motion energy – energy stored in movement of objects. Sound energy – the movement of energy through substances in longitudinal waves. Electrical energy – the energy associated with electric charges and their movements. Flow – to move or run smoothly with unbroken continuity, as in the manner characteristic of a fluid. Nonrenewable energy – fuels that cannot be easily made or “renewed.” We can use up nonrenewable fuels. Oil, natural gas, and coal are nonrenewable fuels. Renewable energy – fuels that can be easily made or “renewed.” We can never use up renewable fuels. Types of renewable fuels are hydropower (water), solar, wind, geothermal, and biomass. Fossil fuels – fuels (coal, oil, natural gas, etc.) that result from the compression of ancient plant and animal life formed over millions of years. Carbon emission – the expulsion of carbon dioxide by the burning of various fossil fuels. Alternative energy – non-conventional energy often created by natural gas, or biomass.
