ENERGY SOURCES

WIND POWERWind power is the use of air flow through wind turbines to mechanically power generators for electricity.

WIND POWERPROS AND CONS

Wind energy is a green energy source and does not cause pollution.

The potential of wind power is enormous – 20 times more than what the entire human population needs.

Wind power is renewable and there is no way we can run out of it (since wind energy originates from the sun).

Wind turbines can be a threat to wildlife (e.g. birds, bats).

Noise is regularly reported as a problem by neighboring homes.

How wind turbines look (aesthetics) is a legitimate concern for some people.

ADVANTAGES DISADVANTAGES

WAVE POWERWave power is the transport of energy by wind waves, and the capture of that energy to do useful work – for example, electricity generation, water desalination.

WAVE POWERPROS AND CONS

Advantages

Green

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

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

Disadvantages

Environmental Effects

Power farms on shore that are visible from land may cause conflicts with tourism and local acceptance. Costs

Wave power is in very early stages of development, which makes speculating on costs harder.

GEOTHERMAL POWER

Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter.

GEOTHERMAL POWERPROS AND CONS

ADVANTAGE

Almost entirely emission free Zero carbon The process can scrub out sulfur that

might have otherwise been released No fuel required (no mining or

transportation) Not subject to the same fluctuations as

solar or wind

DISADVANTAGE

Prime sites are very location-specific Prime sites are often far from

population centers Losses due to long distance

transmission of electricity Water usage Sulfur dioxide and silica emissions
