Friction : a force produced when objects rub together.
Solar Energy : radiant energy (mostly visible light and infrared radiation) produced at the Sun’s outer surface and radiated out into space
Conventional Energy Source : a source of energy that has been widely used for many years.
Hydroelectric Energy : electrical energy produced from moving water
Renewable Energy Resource : a source of energy that can be used indefinitely without running out.
Nuclear Energy : energy released from the nucleus of atoms
Non-renewable Energy Source : a source of energy that could eventually run out.
Fossil Fuels : concentrated sources of chemical energy like coal and oil (petroleum) that were formed deep in Earth’s structure millions of years ago from decayed and compressed plant and animal matter.
Thermal-Electric Power : electricity generated by burning fuels to produce steam
Greenhouse Effect : a rise in temperature resulting from certain gasses in the lower atmosphere trapping radiant energy and warming Earth’s surface.
Greenhouse Gases : gases such as water vapour, carbon dioxide, methane, and nitrous oxides that trap energy in Earth’s atmosphere.
Global Warming : an increase in Earth’s global temperature due to changes in the atmosphere that enhance the greenhouse effect.
Earth’s Energy Balance : the balance between energy lost by Earth and energy gained by solar radiation trapped in Earth’s atmosphere.
Alternative Energy Source : a source of energy that is not as common as conventional sources, alternative energy sources tend to be renewable and have fewer negative impacts on the environment.
Wind Energy : energy from moving air used to generate electricity
Wave Energy : energy generated from moving ocean water
Wind Turbine : device that converts wind energy into electrical energy
Passive Solar Heating : heating caused by the passage of radiant energy through the windows of buildings.
Active Solar Energy System : a device that harnesses radiant energy from the Sun and converts it into a more useful form of energy.
Photovoltaic Panels : panels that convert sunlight into electricity
Geothermal Energy : heat energy from within Earth
Heat Pump : device that transfers thermal energy from one place to another
Biofuels : a liquid fuel produced from plant and animal materials.
Ethanol : biofuel made from crops like corn
Hydroelectric Dam : structure that stores water to generate electricity
Turbine : device spun by water, steam, or air to generate power
Generator : machine that converts mechanical energy into electrical energy
Climate Change : long-term changes in Earth’s climate patterns
