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
6
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
7
Multiple Choice
What is tidal energy?
8
9
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
10
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
11
12
Multiple Choice
What is wave power or energy?
13
Multiple Select
How many types of Hydroelectricity are there? (Check all that apply)
14
Geothermal energy
Power from beneath the surface of the earth
15
16
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
17
Multiple Select
What is geothermal energy?
18
Three key types of Geothermal energy
Dry steam plant
Flash steam plant
Binary cycle plant
19
Advantage of Geothermal Energy
Renewable
Reduction of nonrenewable energies, like fossil fuels
Limited noise and pollution
Direct use
20
Hottest Know Regions

The key drawback of geothermal energy
Location
Technology is helping to solve that
21
Using Geothermal Energy
Unites States
Philippines
Indonesia
Mexico
New Zealand
Italy
Iceland
