India s ageing dams pose a safety risk, nation must conduct reviews: Study

India has 4,407 large dams of which more than 1,000 would be 50 years or older by 2025, a new study has shown. Older dams pose greater safety risks, cost higher in terms of maintenance and have declining functionality due to sedimentation, stated a study by the Canada-based United Nations University Institute for Water, Environment and Health, released in January. Climate change is also likely to accelerate the ageing of dams, it said. India must conduct a cost-benefit analysis of its ageing dams, and conduct timely safety reviews in order to ensure their operational and ecological safety, as well as the safety of those who inhabit the areas downstream, experts told IndiaSpend.

Iceland, a world leader in clean energy, supports Africa s push for geothermal power

But over the next century, the island nation would pull off one of the great energy makeovers in history, casting off fossil fuels and embracing geothermal power. Today, nearly 100 percent of Iceland s electricity comes from renewable sources, a transformation that has helped make its 366,000 people some of the wealthiest in Europe. For the last decade, Iceland has been working with the United Nations Environment Programme (UNEP) to spark a similar energy revolution in Eastern Africa. Iceland has done everything from financing exploration projects to training future geothermal engineers.
