Renewable energy tidal power

Wave power, tidal power, municipal solid waste, gas from animal wastes (biogas), landfill, peat energy and ocean thermal energy conversion (OTEC) are the other renewable energy sources (RES). Water energy sources are hydropower, tidal and wave technologies. 

The main benefit of tidal power, in comparison with other forms of renewable energy, is its predictability. The timing and force of tides can be predicted with great accuracy, and thus so can the power produced by a plant. The main drawback of this power source is its high initial equipment cost, which runs many times that of conventional power sources. 

The choice of a renewable energy source to power a hydrogen fuel cell system will depend on the geography, climate and other resources of the location. I have chosen photovoltaics as the example power source for hydrogen production because it is available to more people than either geothermal, wind, or tidal. For a person without much technical skill, solar power is easier to implement than wind power. It is also less costly up front and not as dependent on location as the other RE power sources...

It is estimated that marine renewable energy projects have the potential to provide 15 percent of the United Kingdom s electrical needs and about 7 percent of the United States electrical power needs. Research b most active in the coimtries with the most access to wave, tidal, and current power, namely the United Kingdom, Ireland, Portugal, and the United States. Jointly operated projects will be the rule because the marine environment is a harsh one and significant engineering and environmental challenges must be overcome. 

In the next 20 years, hydrokinetic power drawn from the earth s oceans and rivers could account for more than 10% of the world s global electricity market (Wood, 2010). The renewable energy resources from ocean wave, tidal stream, ocean and river current and ocean thermal resources are expected to be the major growth area over the next decade (Marsh, 2009).
