Energy

• Energy


  Capacity to do work
• Mechanical Energy


  Potential Energy - Any type of stored energy (can be chemical, nuclear, gravitational or mechanical)
• Mechanical Energy


  Kinetic Energy - Energy found in movement
• Thermal Energy


  Also called as internal energy - Energy that comes from heat - Total energy coming from the attractive and repulsive forces of all the particles or molecules in a body
• Heat Energy


  Energy which flows from one body to another due to a temperature difference between them and the flow is always from the hotter to the colder body
• Electrical Energy


  Can be used to move charged particles through a wire from a power plant to our homes - Energy of electrons flowing through conductors, like copper wires and aluminum wires
• Chemical Energy


  Stored in chemical bonds of atoms and molecules
• Radiant Energy


  Energy of the electromagnetic waves, radio waves, infrared rays, visible light, ultraviolet rays, x rays, and gamma rays
• Nuclear Energy


  Stored potential of the atom's nucleus
• Energy Resources


  Something that can produce heat, power life, move objects, or produce electricity
• Fuel


  Combusting matter to maintain fire, to create heat and power
• Renewable Energy Resources


  Renewed again to again at a faster rate than nature and human consumption
• Solar Energy


  Major future sources of energy - Radiation from sun to produce heat, chemical reaction, generate electricity
• Hydro Energy


  Made to fall form height to rotate turbine, which help generate electricity - Dams - Mechanical energy into electrical energy
• Wind Energy


  Wind is allowed to rotate the blades of wind mills, which rotate turbines to generate electricity
• Biomass Energy


  Dead organic matter or dead plant and animal parts burned to create fuel
• Geothermal Energy


  Thermal energy inside the earth - Converting hot water beneath earth's surface into electricity - Geothermal Reservoir - Natural collection of hot water
• Non-renewable Energy


  Formed inside the earth's crust at a very high temperature and pressure - Present in limited amount
• Fossil Fuels


  Formed from heat and compression of earth's waste and other organic matter - Formed from the decomposition of plants and animals from millions of years ago
• Coal


  Most abundantly found fossil fuel - Mined, formed from trees and other vegetarian buried in swamps created by the encroaching sea
• Petroleum


  A liquid mixture of gaseous liquid and solid hydrocarbons - Natural underground fossil energy resources - Formed due to the decomposition of microplankton deposited upon the sea beds, lakes, and river of millions of years
• Natural Gas


  Composed of entirely of carbon and hydrogen - Mixture of hydrocarbon gases trapped under the earth's surface - 50 to 94% methane and other hydrocarbons
• Nuclear Energy


  Highly developed alternative for energy production in place of coal - Nuclear fission - Atoms split apart which releases energy - Split into two or more smaller nuclei - Nuclear fusion - Two light nuclei merge to form a single heavier nucleus which creates energy
