As China forges ahead with its goal to generate 120,000 megawatts of renewable energy by 2020, they are damming more and more rivers. According to China, this is a safe strategy that will curb pollution, control floods, and minimize climate change. Conservationists and scientists across the globe however, disagree. (more…)

Carnegie Wave Energy (Carnegie) is an Australian company that develops and commercializes wave energy technology that can not only provide power but also desalinated water.
Carnegie says it will build the world’s first wave-powered desalination plant that will generate energy as well as fresh water (see CleanTechnica (more…)

Belo Monte Dam is a controversial mega dam being built in the Amazon on Indigenous land. The old project conceived during the military dictatorship (1964-1985), and which was revived by the Lula government, is the bête noire of Brazilian environmentalists due to the damage it will cause to a pristine region in the Amazon. It will pave the way to tens of other dams in (more…)

Just under two years ago, Energy Refuge went to Ontario for a conference on water technology. At the time, we visited the site of the Niagara Tunnel Project, when a hard-rock tunnel boring machine had finally broken through the other side.
Now, the Ontario government has just finished the (more…)

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 (more…)
