LONDON — The world's largest offshore wind farm had its grand opening Thursday — and its location on the estuary of the Thames River makes it a showcase for Britain's push to move beyond fossil fuels. So far, 100 wind turbines have been planted in waters up to 80 feet deep across the estuary in southern England. The idea is to produce enough electricity, 300 megawatts, to power the equivalent of 200,000 homes. Each turbine is nearly as tall as a 40-story building and the blades are at least 65 feet above the water for clearance with vessels. No turbine is closer than 1,600 feet to another and the entire "farm" covers an area of 22 square miles. Up to 341 turbines will be installed over the next four years. With Thursday's opening, which tops a 91-turbine farm off Denmark, Britain now has more offshore wind capacity than the rest of the world combined. in now gets three percent of its electricity from renewables but aims to get 15 percent by 2020. As part of that, the government this year awarded licenses to wind farm developers in a program that could deliver up to 32 gigawatts of generation capacity and require investment of more than $117 billion.

The green energy future envisions a technological road that leads to an infinite supply of power, independence from potentially hostile nations and an atmosphere cleared of the excess heat-trapping gases that are blamed for warming the planet. The track to this future, however, is full of technological and policy hurdles. Clean up the existing supply with a price on carbon Store wind and solar energy for later use Limit impact of transmission lines Drive down costs of electric cars Build a portfolio of transportation options Mine the earth for rare minerals Grow energy crops; save the food Bury hang-ups on nuclear waste Read full article at MSNBC
With four scrawny fuselages and wings stretching more than the length of a football field, Boeing Co.’s solar-powered drone looks a bit like a flying antenna. But the government is hoping that the aircraft, dubbed the SolarEagle, will one day be capable of flying for five straight years at 60,000 feet. Last week, Boeing announced it had won an $89-million contract with the U.S. Defense Advanced Research Projects Agency to develop a prototype of the SolarEagle that can demonstrate it can stay aloft for 30 days by 2014. Eventually, Chicago-based Boeing sees the SolarEagle hovering at stratospheric altitudes for at least five years. "That's a daunting task, but Boeing has a highly reliable solar-electric design that will meet the challenge,” Pat O'Neil, the plane’s program manager, said in a statement. The SolarEagle will draw on solar energy through panels affixed to the wings. The power will be stored in fuel cells and used through the night. The plane will also feature electric motors and propellers. Much of the design work is being done by Boeing engineers at its Phantom Works facility in Huntington Beach. Boeing expects the plane to be ultimately used as a spy and communication aircraft. Source - LATimes Blog
New technology was unveiled last week that allows ordinary everyday surfaces like windows to be converted into solar panels by spraying on a special coating. Maryland-based technology developers New Energy Technologies, Inc., said their spray-on solar panels could even generate power from artificial light on glass surfaces inside commercial buildings. The company showcased a small-scale working prototype of its "SolarWindow" system at a public demonstration on Thursday at the University of South Florida, in Tampa. Less than a tenth the thickness of solar thin-films, SolarWindow makes use of some of the world's smallest functional solar cells, as developed by University of South Florida physicist Xiaomei Jiang. Researchers are currently working toward lower production costs and increased power performance, along with methods for applying power-producing coatings to glass surfaces. John A. Conklin, the firm's President and CEO said: "Today's public demonstration is a pivotal milestone not only for the dedicated research team, but for our external stakeholders as well, including our investors who are keenly aware of how the development of the highly-anticipated SolarWindow technology has the potential to create a fundamental paradigm shift in the way we produce power worldwide."

Like the little engine that could, the University of Nevada, Reno experiment to transform wastewater sludge to electrical power is chugging along, dwarfed by the million-gallon tanks, pipes and pumps at the Truckee Meadows Water Reclamation Facility where, ultimately, the plant’s electrical power could be supplied on-site by the process University researchers are developing. “We are very pleased with the results of the demonstration testing of our research,” Chuck Coronella, principle investigator for the research project and an associate professor of chemical engineering, said. “The process to dry the sludge to make it burnable for a gasification process, which could then be transformed into electricity, is working very well. This is an important step for our renewable energy research, processing about 20 pounds an hour of sludge in a continuous-feed system to produce about 3 pounds an hour of dried powder.” The team of researchers custom built the processing machine in a lab at the University and brought it to the plant for testing. It uses an innovative process with relatively low temperatures in a fluidized bed of sand and salts to economically produce the biomass fuel from the gooey sludge. Read full release here.
Cannon Power Group Closes $547 Mill Power Sales Transaction With So. California Public Power Authority
Del Mar-based Cannon Power Group announced today the closing of the sale of a 20-year block of renewable power to Southern California Public Power Authority (SCPPA) for $547 million. This is believed to be the largest transaction of its kind in the power industry. The power will be provided from Cannon Power Group's 262-megawatt (MW) Windy Flats wind project in Goldendale, Washington under a long-term power purchase agreement entered into last year by the parties. "This uniquely structured transaction is a true win-win for both parties," said Gary Hardke, president of Cannon Power Group. "It combined SCPPA's low-cost, tax exempt bond financing with the federal stimulus grant program to produce a very attractive long-term cost of renewable power." SCPPA reportedly closed its 20-year bond financing at the end of August at pricing of less than four percent, according to Bloomberg News. Cannon Power Group received total federal stimulus grants of $220 million in connection with the project. "This was really a remarkable and innovative transaction," said attorney Tom Trimble, partner and co-head of the Renewable Energy Practice at Washington D.C.-based Hunton & Williams, who represented Cannon Power Group in the transaction. "It allowed the parties to navigate the credit crisis and take advantage of the low interest rate environment." Cannon Power Group's Windy Flats project went on line earlier in 2010. It is part of the company's 500 MW Windy Point/Windy Flats project. The project, one of the largest wind projects in the United States, and representing an investment of over $1.2 billion, spans over 26 miles along the Columbia River. It is expected to be completed in 2011 and has provided over 350 new jobs to the local area. Cannon Power developed and constructed the project.
Over time, most solar cells degrade due to prolonged exposure to the sun's scathing rays and are rendered useless. But with a little inspiration from nature, researchers have now created a new solar material that regenerates its damaged energy-capturing packets on-demand. A small prototype solar cell built from the self-healing material can continuously produce electricity for an entire week without losing any efficiency, the scientists report. The team was inspired by plants in nature. The ingredients within a plant’s leaves that turn sunlight into energy aren't actually immune to the sun’s damage. Instead, the molecules do their job (pump out sugar), get destroyed, and in less than an hour they regenerate. This process happens over and over again – enabling the leaves to produce energy at the same efficiency as they did on day one of their operation. Read the full article by Michelle Bryner here.

The Greenasium really wants to be green. To do it, the new gym in San Diego is turning its customers into real gym rats. The Greenasium , which opened Wednesday, has three specialty spin bikes straight out of Gilligans Island that push electricity back into the grid, helping provide power to the gym and other electricity customers. Its the first human-powered fitness studio in San Diego, according to its owners. "The bike's are retrofitted by a company up in Seattle that we work with called Resource Fitness ," said Greenasium's co-owner Byron Spratt. "As the bike (spins), the wheel creates DC power, converts it to AC power, which is plugged back into the wall, which puts energy back into the grid." Spratt expects to add elliptical bikes in October to help offset their carbon footprint to an even greater extent.
Salt Lake County and its project partners, NexGen Energy and Bella Energy, announced the construction in downtown Salt Lake City of one of the largest roof-top solar panel installations in the United States. The estimated 600,000 square-foot system will be built atop the Calvin L. Rampton – Salt Palace Convention Center. When completed, the system will produce 2.6 megawatts of electricity, one-quarter of the annual needs of the convention center. The team presented a plan to install up to 2.6 megawatts of solar modules on the structure. If built to that capacity, the Salt Palace will host the largest rooftop solar facility in the United States, generating more than 3,330,000 kilowatt hours of electricity every year while reducing the building’s consumption by 25%.
Deere & Co. said Tuesday it would sell its John Deere Renewables unit, including wind farms, to Exelon Corp. in a deal valued at $900 million. Exelon said it's expanding its role in the wind generation business by adding 735 megawatts of wind energy, plus 230 megawatts under development, via the deal. Deere plans to take an after-tax charge of approximately $25 million in its fourth quarter results as part of the sale. Exelon said it would use debt to pay for the deal.

With MECASOLAR in Italy , the multinational will reach at the end of the current year 282 MW accumulated in tracker installations throughout the world, a figure which is equivalent to the manufacture and start up of more than 22,000 solar trackers in countries such as the United States, Greece, Italy, Germany, France or Spain, among others.
According to a new study of online American adults from the Consumer Electronics Association (CEA)®. The study, Electric Vehicles: The Future of Driving, suggests electric vehicles entice consumers with improved environmental quality and potential cost savings, but leave them with questions about battery life and convenience of battery charging. Consumers are open to considering an electric vehicle in the future, with 42 percent reporting they are likely to follow news reports about electric vehicles. However, overall awareness of the various types of alternative vehicles remains low. While nearly one-third (32 percent) report they are familiar, or very familiar, with hybrid vehicles, only about one-quarter are familiar with electric-powered vehicles (25 percent). The study finds running out of battery power on the road (71 percent), lack of charging stations and/or not being able to recharge (66 percent) and limited mileage (59 percent) are the most common perceived disadvantages with electric vehicles. Home charging stations may also impact purchase decisions. Half of consumers (51 percent) would be less likely to consider purchasing an electric vehicle if they would have to install special charging equipment for the batteries.
