Wind Power, Solar Power, Hydroelectricity, Geothermal Energy, and Biomass Energy are what?
Renewable Energy's
100
are renewable and are thought to be "free" energy sources. They all have lower carbon emissions, compared to conventional energy sources.
Alternative Energy's
100
is the percentage of energy put into a system that does *useful* work.
Energy Efficiency
100
means saving energy.
Energy Conservation
200
"Power from the Sun"
Solar Energy
200
is a form of hydropower that converts the energy of the tides into electricity
Tidal Power
200
an object that uses electricity as well as petrol to propel it.
Hybrid Car
200
materials used to reduce the rate of heat transfer, which is used on windows and doors. Also is the best way to Conserve energy in your home.
Insulation
300
a renewable resource that accounts for about 20 percent of the world’s electricity.
Hydroelectricity
300
The most abundant element in the universe, and can be burned as a fuel.
Hydrogen
300
the least energy efficient conversion device.
internal-combustion engine
300
More useful energy, Low cost energy and the decline of unemployment
benefits of insulation
400
An energy source that doesn't have it's origin in energy from the sun.
Geothermal Energy
400
an object that combines hydrogen fuel with oxygen from the air.
Fuel Cell
400
the production of two useful forms of energy from the same fuel source.
Cogeneration
400
Walking or riding a bike, carpooling, recycling and unplugging unused appliances.
Conserving energy in our daily lives.
500
an object that converts the sun’s energy into electricity.
Photovoltaic Cells
500
an object that uses the temperature difference between cooler deep and warmer shallow or surface seawaters to run a heat engine, usually in the form of electricity.
Ocean Thermal Energy Conversion or (OTEC)
500
an object that uses the most electricity in your home (Hint: Turn on the _____ its hot).
