The U.S. Electric Power Research Institute is currently testing a turbine designed for generating hydroelectricity with significantly reduced fish mortality. The turbine, designed by Alden Laboratories, aims to provide safer passage for fish migrating downstream. Current methods of protecting fish, such as bypasses and non-generating spills, are estimated to reduce the amount of hydroelectic power produced by as much as 8,500 megawatt hours per annum in the United States alone. Instead of the six or more blades common in older turbine designs, the Alden turbine has only three blades, reducing the chance that fish will be struck by a blade. … Continue Reading
Nine European countries have agreed to work together to build an electricity "super-grid" which will allow them to integrate their renewable energy production and storage facilities. The nine countries – Germany, France, Belgium, the Netherlands, Luxembourg, Denmark, Sweden and Ireland and the UK – are planning a network made up of thousands of kilometres of highly efficient undersea cables that could cost up to €30 billion ($au47 billion). The network would connect wind turbines off the coast of Scotland, solar panel arrays in Germany and wave power plants off Belgium and Denmark with hydro-electric dams in Norway. More than 100 … Continue Reading
Such as Australia’s Snowy Mountains Scheme: How It Works The Australian Institute of Energy has produced a Fact Sheet on hydroelectric power with a focus on small (grid-connected) and micro (not grid-connected) systems. Click here to download the Fact Sheet (687K pdf).
Seven African governments and the world’s largest banks and construction firms met in London this week to plan the most powerful dam ever conceived – an $US 80 billion hydro power project on the Congo River. The Grand Inga dam in the Democratic Republic of Congo would generate twice as much electricity as the world’s current largest dam, the Three Gorges in China. The dam would be about 145 kilometres from the mouth of the Congo, the world’s second largest river, where the river drops 100 metres in about 14 kilometres of rapids. One proposal is for a dam 150 … Continue Reading
