Question | Answer |
Biomass | Plant materials and animal waste used especially as a source of fuel. |
BTU (British Thermal Unit) | The heat equal to 1/180 of the heat required to raise the temperature of one pound of water from 32 degrees Fahrenheit to 212 degrees Fahrenheit at a constant pressure of one atmosphere. |
Chemical Energy | The potential energy locked within a system and released during a chemical reaction. |
Climate Change | Any significant change in measures of climate, such as temperature, precipitation, or wind, lasting for an extended period of a decade or longer. |
Conservation | The process of controlling resources; for example, limiting soil erosion, reducing sediment in waterways, conserving water, and improving water quality. |
Efficiency | The ratio of the useful energy delivered by a dynamic system to the energy supplied to it. |
Electrical Energy | Energy associated with the flow of electrons. |
Electricity | The flow of electrical power or charge. |
Energy | The ability to do work; types include heat, light, sound, chemical, nuclear, mechanical, electrical. |
Environment | External surroundings. |
Exhaustible Energy | Any source of energy that is limited and cannot be replaced when it is used, such as oil, coal, and natural gas. |
Fossil Fuel | A natural fuel such as coal or gas formed in the geological past from the remains of living organisms. |
Geothermal | Energy stored in the earth in the form of heat. |
Greenhouse Effect | The phenomenon where earth's atmosphere traps solar radiation, caused by gases(carbon dioxide, water vapor,& methane) in the atmosphere that allows incoming sunlight to pass through but absorb heat radiated back from the earth |
Heat (Thermal) Energy | Energy in transit. |
Hydroelectric Energy | The use of flowing water from waterfalls and dams to produce electricity. |
Hydrogen | The first and simplest element on the periodic table. It is one of the most common elements in the galaxy. |
Inexhaustible Energy | An energy source that will never run out. |
Joule | The unit of energy or work in the MKS system of units, equal to the work done by a force of one Newton-meter. |
Kinetic Energy | The energy possessed by a body as a result of its motion. |
Law of Conservation of Energy | Energy can be neither created nor destroyed. There is a fixed amount of energy present in different forms that can be converted from one form to another, but energy does not go away. |
Light (Radiant) Energy | Energy visible to the eye. |
Mechanical Energy | Energy produced by mechanical devices, such as gears, pulleys, levers, or internal combustion engines. |
Natural Gas | Gas usually found within the vicinity of petroleum reserves. |
Newton-Meter | A unit measure of work. |
Non-Renewable Energy | A resource that cannot be replaced once used. |
Nuclear Energy | The power of the atom. |
Petroleum | Oil. |
Photovoltaic Cell | A device that converts light into electricity. |
Potential Energy | The energy that a piece of matter has because of its position or nature or because of the arrangement of parts. |
Power | The rate at which work is performed or energy is expended. |
Power Grid | A system by which electrical power is delivered throughout a region. |
Renewable Energy | A resource that can be replaced when needed. |
Solar Energy | Energy from the sun. |
Sustainable | Refers to the use of resources in ways that prevent their being depleted or permanently damaged. |
Watt | A measure of power equal to one joule of work per second. |
Wind Energy | Energy derived from wind by means of windmills or wind turbines. |
Wind Farm | A collection of wind turbines used to create electricity. |
Wind Turbine | A propeller driven by the wind and connected to a generator. The wind makes it turn the generator, which produces electricity. |
Work | A result of a force moving an object a certain distance. |
