AeroCam wind turbine enables distributed power generation in densely populated urban areas
Renewable energy from the wind, which previously could only be generated in restricted geographic locations – typically off-shore or in remote rural areas – can now be made available almost anywhere, including urban environments, with the introduction of the AeroCam wind turbine. The AeroCam, developed by BroadStar Wind Systems, was designed and patented for commercial applications. With its parallel rotor blades, not only does it look radically different from conventional propeller designs, but also can be manufactured, transported, installed and maintained at lower cost. “Wind energy n...

GE Energy to supply 200 wind turbines to enXco
enXco, the US subsidiary of EDF Energies Nouvelles, has signed another contract with General Electric Energy covering the supply of 200 turbines with 300 MW in capacity. The turbines with unit capacity of 1.5 MW are due to be delivered in 2010. They are intended for use in the wind energy projects being developed by enXco. This order follows on from a similar order signed in December 2007 covering 300 MW due for delivery in 2009 and will strengthen the relationship built over several years between EDF Energies Nouvelles and GE Energy. ...

Microgeneration to include air source heat pumps
The House of Lords has agreed to support the expansion of the statutory definition of ‘microgeneration’ to include air source heat pumps in a debate held earlier this week. John Kellett, the General Manager of Mitsubishi Electric’s Heating Department welcomed this news: “If we are truly to do something about the country’s carbon emissions then we must find ways of helping the consumer be green and heat pumps offer us that potential,” explained John Kellett. “Getting recognition from our Government is another sign of support for modern air source heat pumps which can help homeowners cut CO2...

New Solar Tower Technology for Southern California Edison
Southern California Edison (SCE) has signed a contract to procure an additional 245 megawatts of solar power for its customers with Pasadena, Calif.-based eSolar in the nation’s first commercial effort using power tower solar thermal technology. The project, which will be built in the Lancaster area of California, is expected to begin delivering energy in 2011, with a total of 105 megawatts of renewable solar power by 2012, ramping up to 245 megawatts by 2013. Each pre-fabricated module consists of several solar towers each associated with thousands of heliostats, or mirrors. The mirror... [more]
Delmarva to purchase 100 megawatts of land-based wind power
Delmarva Power and Synergics Wind Energy have signed long-term contracts under which Delmarva would purchase up to 100 megawatts of land-based wind power to help meet its renewable energy goals in Delaware. The contracts provide Delmarva Power’s customers with wind energy and renewable energy credits (RECs) at prices lower than those offered under Bluewater Wind’s offshore proposal. “These contracts demonstrate that, with land-based wind power, we can obtain clean, renewable energy for our Delaware customers at extremely competitive prices and deliver it to them in the next 18 months,” s...
