The first wind farm in SA, which produces electricity from wind power, was switched on by minerals and energy minister Buyelwa Sonjica, in Darling, Western Cape on Friday, the Central Energy Fund (CEF) said. The R75-million national demonstration project is the first "green energy" initiative in the country to produce electricity from wind power on a commercial basis - this coming against the backdrop of the national energy emergency, it said in a statement.

In this small region of Nigeria known as the "south-south," something huge is happening. The adverse effects of oil exploration have been unfolding in the Niger Delta for the past 50 years. Now, the people have had enough. From environmental activism to peaceful protest to stakeholder dialogs, nothing has worked. A new brand of militancy has emerged in a different kind of attempt to call attention to the desperate poverty and injustice.

We are familiar with the notion of getting an expert second opinion when an expert medical specialist has diagnosed life threatening circumstances. However a second opinion that is a bit more optimistic simply decreases the perceived odds of death somewhat - the dire initial prediction remains.

Energy Future: Think Efficiency differs from other energy efficiency reports in its emphasis on scientific and technological options and analysis. Developed by a panel of leading experts in energy policy with backgrounds in physics, engineering, economics, and policy, Energy Future: Think Efficiency examines what works, what can work soon, and what is feasible for the future. Based on emerging technologies, this report targets which research and development gives America the best return for its dollars.

Drill, drill, drill. Suddenly, oil and gas exploration is all the rage on Capitol Hill. With energy prices a red-hot political issue, the Democratic-controlled Congress, in the midst of its final, three-week legislative sprint before the presidential elections, can't get enough of drilling bills. Not that most Capitol Hill watchers seriously believe that - in the absence of a major supply disruption - any substantive energy legislation will actually emerge from this frenzy and become law. "You don't pass energy bills in the heat of the campaign season," noted Frank Maisano, an energy specialist with Bracewell & Giuliani. Still, there should be plenty of action.

The Age recently had an article on the emerging practice of "guerilla gardening", taking a look at the "Gardening guerillas in our midst". This concept seems to have steadily increased in popularity in recent years (admittedly from a very low base) as the permaculture movement's ideas have been propagated through the community. Unlike the usual approach taken when trying to grow food in the suburbs - converting spare land on your own property (as discussed by aeldric previously and, more recently, in Jeff Vail's series on A Resilient Suburbia) - guerilla gardening involves cultivating any spare patch of urban land that isn't being used for another purpose, which could provide a substantial addition to the food growing potential of suburbia.

The future of the world's largest offshore wind farm and a symbol of Britain's renewable energy future was thrown into doubt last night after it emerged that Shell was backing out of the project and indicated it would prefer to invest in more lucrative oil schemes.

Bleeding from inside the nose is called epistaxis .It can occur in any age group namely children,middle aged and elderly.Epistaxis is a very common cause of emergency visits.

Next100 has a report on the introduction of LED street lighting in some sections of San Francisco - Brightening Up San Francisco's Tenderloin. San Francisco's gritty Tenderloin district will shine a little brighter thanks to a new streetlighting program announced today by Mayor Gavin Newsom, the San Francisco Public Utilities Commission and PG&E. Newsom press conf 3-25-09.JPGAt a press conference this morning on Turk St., joined by PG&E's senior vice president for public affairs, Nancy McFadden, Newsom said the city is installing 50 ultra-efficient, energy-saving LED streetlights in the depressed neighborhood, a smart move to enhance public safety while demonstrating environmental leadership and saving money. In addition, city authorities are working with PG&E to evaluate "smart controller" technology that will monitor the performance of individual streetlights, adjust their intensity, and signal when they are about to fail. Flexible controls will give officials to ability to turn selected lights on or off, dim them, or flash them to alert emergency personnel.

During Earth Week, visitors to the U.S. Department of Energy website -- energy.gov -- will be immediately directed to a special web feature giving them key energy saving tips and user-friendly information about the critical emerging technologies and initiatives underway to move the nation toward a clean energy economy. The webpage is intended to help people enjoy a more green lifestyle by making simple adjustments. It details steps consumers can take to make informed energy decisions, save money on monthly bills, become more energy efficient, and protect the environment. These money saving tips include monitoring energy usage in homes, purchasing fuel efficient hybrid and plug-in hybrid cars, insulating homes, using Lighting Emitting Diodes (LED) and Compact Florescent Light (CFL) bulbs and using power strips to fully shut off multiple appliances and electronics at once when not in use. "Earth Week is a fitting time for all of us to reevaluate our personal energy habits," Secretary Chu said. "By taking simple steps to reduce our energy use, all Americans can strike a blow for energy independence, while saving money on energy bills and moving America toward a clean energy future."

Technology Review has an update on cheap, energy efficient OLED lighting - Ultra-Efficient Organic LEDs. An organic light-emitting diode (OLED) developed in Germany has the potential to produce the same quality of white light as incandescent bulbs but with power efficiencies considerably better than even fluorescent lighting. The prototype OLED could emerge as an ultra-efficient light source for displays and general lighting, says Sebastian Reineke, who led the research at the Institute for Applied Photophysics, in Dresden, Germany. The long-term goal is to fabricate the device using conventional low-cost roll-to-roll printing. In recent years, many countries have begun looking to switch from incandescent lighting to compact fluorescent bulbs because the latter are so much more energy efficient. There has also been a lot of interest in using light-emitting diodes (LEDs) for displays and general lighting, again because of the potential energy savings they offer. But with both fluorescent and LED lighting, the quality of white light produced has always left something to be desired. Fluorescent lighting can make people appear unhealthy because less red light is emitted, while most white LEDs on the market today have a bluish quality, making them appear cold.

TreeHugger has a post on a solar thermal power plant planned for Arizona (Which isn't the largest announced, but how many of these get built in the short term remains to be seen) - Largest Solar Plant in the World Coming to Arizona ?. Could be--details are still emerging and sketchy, but it looks like one of the world's biggest solar projects will find its home in Arizona. The proposed 340 megawatt system would use advanced parabolic trough technology, and would cost over $2 billion--and yes, it would take advantage of stimulus funding. Looks like Arizona's becoming a hotbed for solar power indeed--this would be the fourth solar plant in Mohave County, AZ alone. Here are the whispered details: Mohave Sun Power and Albiasa Solar are the companies behind the ambitious installation, and they'll be using the same technology as another recently proposed massive solar project:

Juniper's first Global Bandwidth Index Report reveals the latest findings on how consumers are using mobile internet connectivity across developed and emerging markets. The study, carried out by Wakefield Research, surveyed 5,500 consumers in developed markets, including Australia, Germany, Japan, the UK and the US, and emerging markets, including Brazil, China, India and South Africa.
