WASHINGTON (AP) - An Energy Department report concludes that wind turbines can produce a fifth of the nation's annual electricity needs within about two decades. That is about the same share of electricity produced today by nuclear power. Wind energy today accounts for only about 1 percent of the nation's electricity. The government report to be released Monday said by 2030 wind energy could account for 300,000 megawatts of power, or about 20 percent of the total electricity generated.

The man who had predicted the storm was Goesta Wollin. Since the early 1970's he has been convinced that the earth's magnetism affects climate…In 1970 Wollin and a colleague, David Ericson, began to study climatic changes that have taken place since the last ice age, 11,000 years ago. By chance, the same week they finished plotting their temperature curves, an article published in Science outlined the changes in the earth's magnetic field over the identical span of time.

Animal researches have long been puzzled by certain aspects of elephant behavior. In particular they have wondered how apparently random group of elephants, sometimes separated by miles, can manage to move in a cohesive, coordinated manner toward the same destination. Equally mysterious is how, without any discernible means of communication, male elephants are able to track down a female in heat even if she is many miles away.

Greentech Media has a post on one of the major issues facing electric car manufacturers - getting people used to the idea - Learning to Live With Electric Cars. While consumers overwhelmingly say they want plug-in cars, consumers will have to be educated on the differences between them and gas-burning cars, says Debra Reed, CEO of San Diego Gas & Electric, which will take delivery of 10 to 15 all-electrics Nissan when they come out next year. Nissan and SDG&E showed off a "mule" of Nissan's electric commuter today. The functioning vehicle sports the same basic motor and other electronics that will come with the production all-electric cars, said a Nissan spokeswoman. However, it is housed in the shell of an existing car.

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:

Der Spiegel has an interview with Boeing's "chief environmental strategist", Billy Glover, on prospects for biofuel use in air transport (he's very optimistic, but short on detail) - Algae Could 'Supply Entire World with Aviation Fuel'. SPIEGEL ONLINE: Mr. Glover, given the current low price of oil, why would airlines still even be interested in biofuels? Glover: Indeed, the oil price has changed rapidly. But it has done that many times before and it will continue to do so. Even today, the highest operating expense for an airline is fuel. It remains a priority to find a way to mitigate that situation. That is why Boeing is trying to open up this avenue of alternative fuel. It can help that situation while having a better environmental performance at the same time.

During a visit to Fort Wayne, Indiana, where he toured a manufacturer of geothermal heating pumps (GHPs), U.S. Energy Secretary Steven Chu today announced nearly $50 million from the American Reinvestment and Recovery Act to advance commercial deployment of the renewable heating and cooling systems, which use energy from below the Earth's surface to move heat either into or away from the home or building. The expanded manufacturing and installation of GHPs could aid in the creation of new jobs while reducing the use of fossil fuels. "The heat from the Earth represents a significant energy resource that can be tapped to reduce emissions contributing to climate change." said Secretary Chu. "Expanded use of GHPs in the United States will create new jobs for engineers, manufacturers and technicians while at the same broadening our nation's clean and renewable energy portfolio."

Waldo's message to you is simple - whether achieving victory as a fighter pilot, in business, or in life, the same qualities that ensure success apply: focus, discipline, integrity, teamwork, leadership, overcoming your fears, and maintaining a commitment to excellence.

The article "Renewable energy potential" (Work&Money, Editor's Choice, June 7) provided interesting and useful information. Now it is time to begin to use more renewable energy in North Carolina. One of our electric utility companies should develop a pilot project in one of the high-wind areas off the North Carolina coast. This energy could be used to provide some power to Elizabeth City, Manteo or any other city located on the northern part of our coast. Our electric utility companies have many intelligent engineers who could use new technology to build wind turbines that can withstand strong storms. If other states in the Northeast can build wind farms off their coasts, then North Carolina can surely do the same.

Compact Fluorescent lamps are becoming very popular for household use and is fast replacing the typical screw based incandescent lamps. The main reason of their popularity is that they use one third of the energy of incandescent lamps and deliver the same amount of light.

Becoming a green lobbyist is not as easy as announcing that you are only going to work on green issues and policies; you must make sure that you are actually adhering to the same goals that you are extolling.

The state began its pursuit of offshore wind generation Tuesday, a move that could lead to building 400-foot-tall turbines off Ocean City. The Maryland Energy Administration asked wind developers to express their interest in building industrial-size windmills a dozen or more miles off the state's 31-mile Atlantic coastline. At the same time, the energy agency said it is launching a study to gauge the economic viability and environmental impact of such a project.

Some people consider their eyeglasses a practical tool - a simple means to an end while other choose their frames the same way they'd select and accessory, such as a pair of shoes, a watch or a handbag. In fact, it's not uncommon for the fashion conscious to purchase several pairs of glasses in significantly different styles, so they can choose exactly the look they want in every situation.
