Technology Chapter 27: Energy: The Foundation of Technology—Terms and Definitions Biofuels: organic material that can be burned or converted into methane. Biogas: A mixture of methane and carbon dioxide produced by the bacterial decomposition of organic wastes and used as a fuel. Biomass: a type of resource having a living origin. Biotechnology: practices that improve propagation, growing, and harvesting activities. Chemical energy: energy stored within a chemical substance. Electrical energy: energy associated with electrons moving along a conductor. Energy: the ability to do work. Exhaustible energy resources: materials that cannot be replaced. Fission: the process of splitting atoms to release vast quantities of energy. Foot-pounds: a measurement of the amount of energy needed to move an object from one location to another. Fossil fuels: exhaustible resources that are mixtures of carbon and hydrogen. Fusion: the process of combining two atoms into a new, larger atom to release large amounts of energy. Horsepower: a measurement used to describe the power output of mechanical systems. Inexhaustible energy resources: a part of the solar weather system that exists on earth. Joules: newtons per meter. Kilowatt hour: the work that 1000 watts will complete in one hour. Kinetic energy: energy involved in moving something. Mechanical energy: energy produced by motion of technological devices. Nuclear energy: energy produced by the fusion of atoms. Potential energy: stored energy. Power: the rate at which work is done. Radiant energy: energy in the form of electromagnetic waves. Renewable energy resources: a biological material that can be grown and harvested. Solar weather system: the natural cycle that starts with solar energy. Thermal energy: heat energy. Water cycle: a cycle powered partially by solar energy. Copyright Goodheart-Willcox Co., Inc. Permission granted to reproduce for educational use only. Watt: one joule of work per second. Work: applying a force that moves a mass a distance in the direction of the applied force. Copyright Goodheart-Willcox Co., Inc. Permission granted to reproduce for educational use only.
