Hydroelectric and Geothermal Energy

Hydroelectric and Geothermal Energy

Renewable energy

Types of Hydro Energy

• Hydroelectric dam energy

• Wave energy

• Tidal energy

Hydroelectric Energy

• Is energy that is taken from water and converted to electricity

• Common Method of obtaining, from Hydroelectric dams

• Water flowing through turbines to rotate and the energy is captured to run generators

• Tidal forces or wave power also

Tidal Energy

• Converts energy from ocean tides to electricity

• Not widely used, it is renewable

• Costs are a driving factor

• Space availability is another concern

• It is effective

Multiple Choice

What is tidal energy?

• Nonrenewable

• A form of hydropower

• Wind

• Nuclear

Wave energy

• Is the ability of ocean waves to generate electricity

• The moon, wind currents, and tidal flow influence wave movement

• There is tremendous energy available

Wave power

• Extracts energy from the surface motion of the ocean waves

• Waves generate wind and pressure

• In a closed tank, that will drive a generator

Multiple Choice

What is wave power or energy?

• Geothermal energy

• Nuclear energy

• Nonrenewable

• The capacity of the waves to generating electricity

• Hydro Dams

Geothermal energy

Power from beneath the surface of the earth

What is Geothermal Energy

• Renewable energy

• Collect heat from underground to generate steam and produce electricity

• Comes from molten rock, magma

• First used 1904; Piero Ginori

What is geothermal energy?

• Wave movement

• Nonrenewable energy

• Collect heat from underground to generate steam and produce electricity

• Nuclear energy

Three key types of Geothermal energy

• Dry steam plant

• Flash steam plant

• Binary cycle plant

Advantage of Geothermal Energy

• Renewable

• Reduction of nonrenewable energies, like fossil fuels

• Limited noise and pollution

• Direct use

Hottest Know Regions
