Transcript of Wave Energy
Can be predicted through satellite measurements, and forecasts
Which helps with network planning
Depending on the waves, sometimes you'll get loads of energy, sometimes almost nothing.
Needs a suitable site, where waves are consistently strong.
Some designs are noisy.
Must be able to withstand very rough weather
Why wave energy?
Wave energy is measured in terawatt-hours/year (TWh/year)
U.S. West Coast:
U.S. East Coast:
The Gulf of Mexico:
Wave energy is still a developing resource, but it is said to be competitive in the near future
What is wave power?
Examples of different wave power
Downsides and Challenges
Form of energy produced with movement of ocean waves
Like solar and wind, wave is a renewable natural resource of energy
The longer the waves travel, the more power they contain
The energy is free - no fuel needed, no waste produced.
Can produce a great deal of energy.
Compared to wind and solar, waves effectively average out the wind that generates them over large areas which results in a high level of consistency.
Abundant and widely available
Different ways to harness
No damage to land
Machines may the seafloor, change the habitat of near-shore creatures and create noise that disturbs the sea life around them
Affects the lives of the people who rely on fishing for a living
Downsides and Challenges Cont'd
Long tube that bobs up and down in the wave
When the hinges bend they, pump hydraulic fluid which drives generators
Underwater equipment on the sea bed near the coast
Waves passing across the top of the buoys, pumps seawater to drive turbines on land
Also used to filter seawater into drinking water
Captures energy in near shore waves and converts it into clean sustainable electricity.
It's wave-powered pump which pushes high pressure water to drive an onshore hydro-electric turbine.

The ocean contains a tremendous amount of power, and people are beginning to realize it's potential
