14 Jan 2013: Tidal Energy Can Meet 20%
Of UK Electricity Needs, Study Says

UK officials are underestimating the vast energy potential of marine tides, a renewable and reliable energy source that could meet 20 percent of the nation’s electricity needs, according to a new report. Writing in the journal Philosophical Transactions of the Royal Society A, researchers explain that while the process of exploiting tidal energy remains expensive, it has the potential to be a more reliable energy source than wind or wave energy and to be more easily managed on electricity grids. While the technology is in the early stages, the researchers say they are optimistic that the two principle means of exploiting tidal energy — construction of barrages across tidal estuaries that generate power from the ebb and flow of the water, and adding underwater turbines in fast-flowing currents — can be implemented in the near future. “From tidal barrages you can reasonably expect you can get 15 percent of UK electricity needs,” Nicholas Yates, a researcher at the National Oceanography Centre and co-author of the report, told BBC News. Yates said that initial projects should be small in scale so that early lessons can be incorporated into future projects. A proposed barrage plan on an estuary of the River Severn, the UK’s second longest river, was rejected because of environmental concerns.
