PROS AND CONS OF OCEAN THERMAL ENERGY AND WAVE ENERGY

1. Waves are hardly interrupted and almost always

in motion. This makes generating electricity from

wave energy a reasonable reliable energy source.

2. A wave farm that is occupying less than a half square

mile of an ocean would generate more than 30 MW of power.

3. Ocean wave energy plants can be put offshore. The benefit of offshore wave power is that there is a larger energy potential in these waves.

4. The larger flexibility as to where to put these

offshore wave farms could potentially minimize

the negative environmental effects wave

power has on the environment.

Disadvantages of

Ocean Thermal Energy

1. OTEC requires expensive, large-diameter pipes submerged about a mile below the ocean's surface. Many

of the countries within the viable geographical belt lack the economic resources to build this infrastructure.

2. Because OTEC facilities are stationary surface platforms, they are essentially considered artificial islands and, therefore, their exact location affects their legal status under the United Nations Convention on the Law of the Sea treaty.

of Wave Energy

5. Harnessing wave energy comes without the emission of harmful green house gases.

6. Like with most green energy sources, wave power is also renewable.

7. The amount power in that comes in waves is huge. The energy density is typically around 30-40 kW for every meter (2.2 feet) of wave along the shore.

1. The costs of wave power and their development

is very high.

2. Power farms on shore that are visible from land may cause conflicts with tourism and local acceptance. Due to this, coastal installations and facilities on land has to meet higher restrictions in terms of size and location.

What is wave energy?

Advantages of

Ocean Thermal Energy

Wave power is the transport of energy by ocean

surface waves, and the capture of that energy to do useful work – for example, electricity generation, water desalination, or the pumping of water (into reservoirs). A machine able to exploit wave power is generally known as a wave energy converter (WEC).

1. OTEC works in an unchanging condition

unlike other renewable sources of energy.

2. OTEC can also support numerous spin-off industries. Chilled water that has already been

used can be pumped out of the plant and used

in air conditioning, industrial cooling and

chill-soil agriculture.

ENERGY CONVERSION

Advantages of Wave Energy

Ocean Thermal Energy Conversion (OTEC)

is a marine renewable energy technology that harnesses the solar energy absorbed by the oceans to generate electric power. The sun’s heat warms the surface water a lot more than the deep ocean water, which creates the ocean’s naturally available temperature gradient, or thermal energy.
