a tidal energy project is moving ahead in Maine, with high costs but high hopes too. But the 180-kilowatt unit that the Ocean Renewable Power Company hopes to put under water next week is really just a first step. The big question is, how well will it withstand the force of the rushing water?

The region, the Bay of Fundy, is famous for strong tides, but the company has picked a spot called Cobscook Bay, where the current is relatively slow, an average of 5.8 knots, or 6.7 miles an hour. That is the speed at which the hardware will produce 180 kilowatts.

Sustainable energy is the sustainable provision of energy that meets the needs of the present without compromising the ability of future generations to meet their needs. Technologies that promote sustainable energy include renewable energy sources, such as hydroelectricity, solar energy, wind energy, wave power, geothermal energy, and tidal power, and also technologies designed to improve energy efficiency.

.In this form of Tidal Power,a Barrage is built near the coast where water is collected during the periods of high tides.During low tide the barrage allows the water from the reservoir to move towards the ocean or sea.The potential energy of the water at a higher level is converted to electricity using Turbines.

Hydropower: Generate Energy with Rivers and Ocean Tides - For Dummies - 0 views
-
When water flows toward the shore with the incoming tide, it flows through a tidal energy system, turning a turbine that generates electricity. When the tide shifts and flows in the opposite direction, away from shore, the tidal energy system again captures the energy with a turbine and converts it into electricity.
-
An important source of alternative energy is hydropower: converting the flow of rivers and ocean waves and tides into electricity through dams and turbines. The best part about both of these water sources is that they’re 100 percent renewable.
-
The main advantage of using ocean tides for energy is that tides and waves are a constant, unchanging, clean source of energy. The main disadvantage is that tidal energy systems may impact the environment by changing the flow of water into shoreline and estuarine ecosystems.

Wave power in the United States - Wikipedia, the free encyclopedia - 0 views
-
Wave power in the United States is under development in several locations off the east & west coasts as well as Hawaii. It has moved beyond the research phase and is producing reliable energy for the Grid. It's use to-date has been for situations where other forms of energy production are not economically viable and as such, the power output is currently modest. But major installations are planned to come on-line within the next few years. Projects

Since 1998, the Pelamis development programme has covered all aspects of the design from the fundamental concept refinement through to accelerated cycle testing of individual components for reliability.
-
During the first phase of Pelamis development prior to full-scale operations in 2004, extensive numerical modelling and analysis and a range of technology demonstration models at different scales were used to understand survival characteristics in extreme waves and verify the accuracy of our simulations
Tidal Energy : Advantages and Disadvantages - 0 views
-
Advantages of Tidal Energy1) It is an inexhaustible source of energy. 2) Tidal energy is environment friendly energy and doesn't produce greenhouse gases. 3) As 71% of Earth’s surface is covered by water, there is scope to generate this energy on large scale. 4) We can predict the rise and fall of tides as they follow cyclic fashion. 5) Efficiency of tidal power is far greater as compared to coal, solar or wind energy. Its efficiency is around 80%. 6) Although cost of construction of tidal power is high but maintenance costs are relatively low. 7) Tidal Energy doesn’t require any kind of fuel to run. 8) The life of tidal energy power plant is very long. 9) The energy density of tidal energy is relatively higher than other renewable energy sources.

Disadvantages of Tidal Energy 1) Cost of construction of tidal power plant is high. 2) There are very few ideal locations for construction of plant and they too are localized to coastal regions only. 3) Intensity of sea waves is unpredictable and there can be damage to power generation units. 4) Influences aquatic life adversely and can disrupt migration of fish. 5) The actual generation is for a short period of time. The tides only happen twice a day so electricity can be produced only for that time. 6) Frozen sea, low or weak tides, straight shorelines, low tidal rise or fall are some of the obstructions. 7) This technology is still not cost effective and more technological advancements are required to make it commercially viable. 8) Usually the places where tidal energy is produced are far away from the places where it is consumed. This transmission is expensive and difficult. Tidal Energy is thus a clean source of energy and doesn’t require much land or other resources as in harnessing energy from other sources. However, the energy generated is not much as high and low tides occur only twice a day and continuous energy production is not possible.
