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 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.

The Town of Hopkinton became the first town in Massachusetts to install solar panels on multiple municipal buildings. The 1,832 solar panel installation, completed by Borrego Solar Systems, Inc., sits atop Hopkinton's High School, Middle School, Police Station, and Fire Department and helped them satisfy the need to compile energy use from all municipal buildings and pledge to have them reduce energy consumption by 20 percent.
Given the rural location of Peter's Durksen's 25-year-old, 1,800 square foot bungalow, he didn't have access to natural gas and was tired of paying the rising costs for fuel oil to power his forced air oil-fired furnace and hot water tank.
What Solar Energy Developers Need to Know
Last January saw solar panel pricing hit historical lows worldwide. As a result and despite the economy, the solar photovoltaic industry is having a pretty good year both at the commercial and residential levels.
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.
