Alternative Energy Concept Review 5.7C

What type of alternative energy do these wind turbines use?

• Solar
• Geothermal
• Wind
• Hydroelectric

Wind Energy

• Energy that comes from changing the power of moving air into a useful form
• Energy generated by natural processes that is renewable
• Materials from the Earth that cannot be replaced
• Energy that comes from the Sun

Electricity made from the energy of moving or falling water

• Wind Energy
• Solar Energy
• Hydroelectricy
• Renewable Resource

Geothermal energy comes from—

• Rushing Water
• Moving wind in Texas
• Natural heat from the Earth
• Heat and energy from the Sun

Energy generated by natural processes that is renewable

• Hydroelectricity
• Geothermal
• Solar
• Alternative Energy Resource

Fuel made from plants, animal wastes, and decomposing plant and animal tissue

• Wind Energy
• Biofuel
• Geothermal
• Alternative Energy Resource

Materials introduced into an environment that cause damage, discomfort, or instability

• Biofuel
• Hydroelectricity
• Solar Energy
• Pollution

Solar Energy

• Energy that comes from the sun.
• Energy that comes from wind.
• Nonrenewable Resource
• Pollution

Materials from the earth that can be replaced by nature within a relatively short period of time; example: trees

• Renewable Resource
• Nonrenewable Resource
• Wind Energy
• Fossil Fuels

"Biofuel is an alternative energy resource because it— "

• Produces energy from running or moving water.
• Uses organic matter that is renewable and readily available.
• Comes from the natural heat from the Sun.
• Takes millions of years to create, but can be harvested quickly.
