While world leaders meet in Paris to discuss reducing carbon emissions believed to contribute to climate change, the government of Gibraltar is putting its own renewable energy plan into action. The iconic British territory has inked a deal with Eco Wave Power to install a 5-megawatt wave energy power station to harvest electricity from the rising and falling waters of the Mediterranean.
With its large tidal range, Britain's Bristol Channel has a huge potential for generating tidal electric power. The problem is that, until now, schemes for tapping that power have required building dams and barrages so gigantic they would have given even the most wild-eyed Victorian engineer pause. As a more economical alternative, Kepler Energy has announced plans for a 30 MW tidal energy fence to be built in the Channel. With an estimated cost of £143 million (US$223 million), the underwater fence would be built in the water somewhere along the line between Aberthaw and Minehead and could be operational by 2021.
