What is Water Power ?
Water power ranges from hydroelectric electricity generated from dams on rivers or lakes and now starting to harness the tides around the uk through to the latest technology harnessing the power of waves in the sea
How is Water Power Harnessed ?
Hydroelectric Flowing of the water that makes the whole system work. Water is allowed to flow in a controlled manner onto blades of some kind attached to a turbine which is then used to create electricity Hydroelectric power dates back to the early 1900s but the use of water to provide mechanical power of falling water dates back more than 2000 years as a means of grinding corn.
Ocean wave energy conversion for utility scale power generation is now becoming a commercial technology. A 75 kW shore-based demonstration plant by Queens University, Belfast, using the OWC process described above has operated on the Scottish island of Islay for 10 years A very simplistic description of how it works is as a buoy goes up and down in the waves it compresses air which then turns a turbine and creates electricity
Where is Water Power used ?
Hydroelectric plants are dotted around the UK on our rivers but the largest and most commercially viable are in Scotland There is the possibility of turning some of our disused water mills to create small power plants is still an expensive option but as our natural resources of fossel fuels continue to dwindle they may come to the fore Wave energy is still in its infancy as a power source but has unlimited potential due to the fact the UK is an island with the ocean all around
Why has hydroelectricity production not increased in the UK to the level we would expect ?
We only have small areas of the UK with all the needed constituents to produce hydroelectricity using dams , but the advance in wave power technology in the UK could mean in 30 years hydroelectricity through wave power could become a major source of power for us External links to good sources of information
