Science and Technology:

  • Water is an ancient power source, one usually exploited by harnessing its flow. For decades, though, scientists have been working on another kind of water power — one relying on salt. This technique exploits the natural process of osmosis. [Wall Street Journal]


  • Solar panel canopies are to be placed above leisure center parking lots in the UK city of Nottingham. In all, the canopies will cost the council £2 million. They should generate £200,000 worth of energy a year, so in ten years they will be generating that free as income. [Nottingham Post]
  • The Samoa government has officially opened the country’s first wind energy project at Vailoa Aleipata on the southern coast of Upolu island. The Aleipata wind farm includes two 55 meter high wind turbines, each with a capacity of 275 kW. [Radio New Zealand]
  • The Russian government has accepted the Energy Ministry’s proposal for Russia to join the International Renewable Energy Agency. Prime Minister Dmitry Medvedev has signed a corresponding document, the cabinet website said on Friday. [ITAR-TASS]
  • Greenpeace volunteers have launched a “peaceful campaign” in front of a solar station in south Amman, Jordan, demanding that the government switch its energy plans from nuclear to renewable. []
  • Two innovative renewable energy projects are moving forward in Scotland: Britain’s first tidal power array, and the world’s first deployment of two-bladed wind offshore turbines. The experimental technologies are hoped to achieve significant cost savings. [The Ecologist]
  • Ecodrive and Wattstor teamed up with the University of Exeter to monitor and manage the monetary value of the most expensive element of an electric vehicle – its battery. The result could produce a change in the way EVs are marketed. [Western Morning News]


  • SolarCity plans a 1 GW integrated PV manufacturing plant to use technology developed by recently acquired Silevo. According to recent reports, the plant is expected to cost somewhere between $400–$450 million. [CleanTechnica]
  • After more than a year of study, United Water has decided to develop a small hydroelectric power plant at the Dundee Dam to produce enough power to supply 1,000 homes. The dam is on New Jersey’s Passaic River, where it runs between Garfield and Clifton. []
  • Utah solar advocates and customers are hailing a decision Friday by the Utah Public Service Commission to reject Rocky Mountain Power’s request of a monthly fee for rooftop solar homes. The commission, in its order, said it could not rule that the fee was justified. [Deseret News]
  • Austin Energy could be a greenhouse-gas-free utility eventually, as the Austin City Council passed a measure requiring the utility to make larger investments in renewable energy. The goal is for the utility to be completely green by 2030. [Austin Business Journal]
  • As utilities across the US grapple with stagnant electricity sales, many see opportunity in the fledgling need for electric-car charging stations. But some companies’ tactics are spurring complaints from consumer advocates. [Wall Street Journal]
