The world's largest is planned for Scotland. The farm will be the world's largest with a capacity of 3MW generated by four Pelamis machines.
During June - September, it has peaks of kW. The monsoon month's average power production was kW. The cost of construction of the power plant was 99 lakhs Indian rupees. The unit cost stands 0. Harnessing wave energy comes of harmful green house gases. This is the main motivation factor behind further development of this way of power generation. We need to find energy sources that will replace polluting ones e.
Like with most green energy sources, wave power is also renewable. Since this energy source ultimately comes from the heat energy that is emitted from the sun, The amount power in that comes in waves is huge. The energy density is typically around kW for every meter 2. As we go further into the ocean kW for every meter is not uncommon. Waves are hardly interrupted and almost always in motion. This makes generating electricity from wave energy a reasonable reliable energy source at least when you compare them to solar and wind.
With considering the increasing of global temperature, and also the concern of global climate change, many policy makers worldwide have been accepted the importance of reducing greenhouse gas emissions, in particular from the power industries so the importance of the renewable energy is obvious.
Wave energy is one of the renewable energy sources. And has the potential to play a valuable part in a sustainable energy future. Wave energy is also one of the predictable energy sources that depending on oscillating the surface of water.
The wave energy system for generation electricity in the last few years has been growing rapidly. The world's largest solar collector absorbs a fantastic amount of the sun's energy: 4, times the amount of electricity used by all humans on the planet.
A typical square mile of the ocean contains more energy than 7, barrels of oil. The ocean contains two types of energy: thermal energy from the sun's heat, and mechanical energy from the tides and waves. Ocean mechanical energy is quite different from ocean thermal energy. Even though the sun affects all ocean activity, tides are driven primarily by the gravitational pull of the moon, and waves are driven primarily by the winds. The tidal rise and fall of the oceans is caused by the varying gravitational pull of the sun and the moon.
The incoming and outgoing tides of the sea can be harnessed to produce electrical power. The heat energy is then used to generate electricity Ocean wave energy is captured directly from surface waves or from pressure fluctuations below the surface. Wave power systems convert the motion of the waves into usable mechanical energy which in lump can be used to generate electricity.
A project to advance understanding of the Sea Power Platform: its response to extreme conditions and the effect of various types of control on both the loading pressures, forces, moments, etc. The Stage 2 project included the undertaking of a series of laboratory tests, numerical modelling activities, and concept development of a full-scale configuration of the technology. The goal of NWEC Stage 2 was to develop a new high-performance WEC geometry and progress it to a viable, fully functioning WEC design that can produce electrical energy when installed in a suitable wave site.

The bulge wave travels at a speed that is determined by the geometry and material properties of the tube. Anaconda is designed so that its bulge wave speed is close to the speed of the external water waves above. In this resonance condition the bulges grow as they travel along the tube, gathering wave energy. Inside the tube, the bulge waves are accompanied by a periodically reversing flow. One way of extracting power from Anaconda is to use a pair of duck-bill valves to convert this power into a rectified flow past a turbine between high and low pressure reservoirs.
