History of Tidal Energy in Europe - 0 views
-
Europe has a long history of employing tidal forces to generate power, and tide mills dating back to the Middle Ages can be found across the continent. A dam with a sluice was constructed spanning a tidal inlet, or a section of a tidal estuary was turned into a reservoir.

Verdant Power founders are planning to install up to 30 turbines with the total capacity of 1MW in the East Channel of the East River, writes The Day news portal.
-
Verdant Power is among the first companies that are exploring the potential of the tidal energy. Unlike the wind and solar power, tidal power is predictable as the tides move in correlation with the movement of the moon
-
The initial costs for the development of this technology are high. The company has raised USD 35 million so far and needs USD 25 million more.

A huge dam (called a "barrage") is built across a river estuary. When the tide goes in and out, the water flows through tunnels in the dam. The ebb and flow of the tides can be used to turn a turbine, or it can be used to push air through a pipe, which then turns a turbine. Large lock gates, like the ones used on canals, allow ships to pass. If one was built across the Severn Estuary, the tides at Weston-super-Mare would not go out nearly as far - there'd be water to play in for most of the time. But the Severn Estuary carries sewage and other wastes from many places (e.g. Bristol & Gloucester) out to sea. A tidal barrage would mean that this stuff would hang around Weston-super-Mare an awful lot longer! Also, if you're one of the 80,000+ birds that feeds on the exposed mud flats when the tide goes out, then you have a problem, because the tide won't be going out properly any more.

Ocean Wave Energy Power Technology - History - 0 views
-
Currently, numerous wave power plants (so called wave farms) have been implemented throughout the world. Many different organizations have designed various wave power systems that differ in size, cost, and effectiveness. A wave farm is a collection of wave power systems in order to create mass quantities of power. One example of a wave power plant is the Aguçadoura Wave Farm in Portugal from Pelamis Wave Power Ltd. It is the first wave farm ever established and produces 2.25 megawatts of power. It was completed in 2008. Other wave farms, with other companies involved, have been proposed.

In contrast to tidal power, ocean wave energy plants do not make use of the energy difference between high tide and low tide, but generating energy from continuous wave motion. So, wave energy generation is the conversion of the forces from the motion of waves into usable energy.
-
Wave energy is considered a form of hydropower, although it is the wind blowing over the surface of the ocean causing waves. So in many ways, wave energy is also wind energy - with all the pros and cons.

Re: How is tidal power converted to electricity? - 0 views
-
Tidal Energy originates from gravitational energy. Imagine you have a damn- like structure built along a river. During the high tide, the water flows into the river, causing the turbine to rotate and thus generating electricity. During the low tide, the water flows from the river to the sea, again, turning the turbine. (An electricity generating turbine consists of rotating wires surrounded by strong fixed magnetic field)
What environmental benefits does tidal energy have compared to the traditional fossil fuel energy production? | Answerbag - 0 views

A benefit is very little pollution. However, there is a very serious potential draw back. It can be very hard of fish populations. The proposal for tidal power is to put turbines on the bottom of a bay and let the water rushing in and out with the tide turn them and generate electricity. However, along with the water will come fish and other marine animals. What do you think will happen when these critters get sucked into the turbines. Can you say sushi, boys and girls? Putting some kind of screen in front of the turbine to prevent this would just mean that the animals would be sucked up against the screens, obstructing the flow of water through the turbines.

Wave Energy Pros and Cons - Tidal and Ocean Wave Power Still Niche Technologies | Green World Investor - 2 views
-
Wave Power is quite immature,costly and unproven in large scale. While some companies have made good progress, the technology remains largely unproven and has only been put to actual test in pilot cases.
-
While Wave Energy has been known since the 1700s the progress has been extremely slow.
-
One of the biggest problems of Renewable Power is that it is intermittent in nature as it generates energy only when there are waves. This problem can be solved with energy storage however this leads to additional costs.

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.
Tides of the Ocean - Windows to the Universe - 0 views

Each day the ocean surface rises and falls because of tides. The highest point of the rise is called high tide. The lowest point is called low tide. Most places have two high tides and two low tides each day. Tides happen because of the gravitational pull of the Moon and Sun on ocean water. The Moon has a much greater impact on tides than the Sun because it is much closer. The Moon pulls water that is closest to it making a high tide on the side of the Earth closest to the Moon and there is a high tide on the opposite side of the Earth too. Low tides happen in places between the high tides. Because Earth is rotating, the tides change over time. The difference between high tide and low tide is called the tidal range. The tidal range can be as little as a few centimeters to as much as several meters depending on the shape of the ocean floor. In Canada's Bay of Fundy the tidal range is very large – 16 meters.
