It's been a while since a major new poo power project graced these digital pages, but this one's certainly worth noting: The Guardian reports that the German town of Lünen, will become the first town in the world to have its own dedicated biogas network:
The 6.8 MW power plant at the heart of the network with take cow and horse manure, as well as other agricultural waste and spoiled crops from surrounding farms, and process it all into biogas, which will be used to generate both heat and electricity. When completed it will generate enough power to supply about 26,000 homes.
About 30-40% of the town's heat and electricity will be provided through the biogas network.
UNH Get's 85% of Power From Landfill Gas
Germany isn't alone in getting in one the biogas act: Closer to home for most TreeHugger readers the University of New Hampshire just completed a landfill gas pipeline, which will supply 85% of the school's heat and electricity.
This was a picture of a cow grazing.. powering up, so to speak!

Spain plugs in largest solar-tower power plant

Spain plugs in largest solar-tower power plant
by Martin LaMonica
At Abengoa Solar's facility in Spain, mirrors heat a liquid in a tower, on right, that produces steam to make up to 20 megawatts of electricity.
Abengoa Solar of Spain on Monday reported successful tests of its second solar tower in operation, in which the sun's heat is used to make electricity.
The 531-foot solar tower, located near Seville, Spain, features a number of improvements on the first design and has exceeded the anticipated output. Called PS20, the installation is the largest in the world with a capacity of 20 megawatts, enough electricity to supply 10,000 homes, according to the company.
A solar tower configuration uses a field of heliostats, or mirrors, to concentrate sunlight onto a receiver held in the tower. The heat creates steam which turns a turbine to make electricity. The PS20 project has 1,255 of these heliostats, with each heliostat having a surface area of 1,291 square feet.
Concentrating solar thermal technology has been used in desert areas in Spain and the southwest U.S. for decades and is seeing a resurgence as utilities seek out cost-effective solar power.
The traditional solar concentrating power uses rows of mirrored troughs that follow the sun over the course of the day.
Solar tower technology is considered the successor technology to mirrored troughs and is being pursued by a number of solar companies, including renewable energy powerhouse Abengoa and California start-ups BrightSource Energy and eSolar.
Abengoa Solar said that this installation improved on the first solar tower in Spain with better control systems and solar thermal energy storage system

Cape Wind Completes State, Local Permitting
Cape Wind Completes State, Local Permitting
SustainableBusiness.com News
Cape Wind completed its state and local permitting process Thursday with a unanimous vote of the Massachusetts Energy Facilities Siting Board.
The proposed offshore wind farm will be granted a ‘Certificate of Environmental Impact and Public Interest’ that rolls up all state and local permits and approvals into one ‘composite certificate’.
Completion of the Federal Permitting process for Cape Wind is expected soon when U.S. Secretary Ken Salazar issues a Record of Decision on Cape Wind. The Minerals Management Service of the U.S. Department of Interior issued Cape Wind a favorable Final Environmental Impact Statement in January.
Cape Wind President Jim Gordon welcomed the news, “Today's vote marks not just a successful conclusion to a seven-year state regulatory review of the Cape Wind project but the beginning of a new era of clean energy jobs and renewable power from the endless wind resources off our shore."
The Massachusetts Energy Facilities Siting Board (Siting Board), was created by the Legislature to ensure the siting of needed and least environmental impact energy facilities and was granted the statutory authority to issue a comprehensive approval to an energy facility it has previously approved, where that facility has been denied a permit by any other state or local agency in the Commonwealth. The Siting Board exercised their statutory authority in their vote Thursday, which was necessitated by a procedural denial issued from the Cape Cod Commission in 2007.
In 2005, the Siting Board approved Cape Wind’s electrical interconnection at the conclusion of a 32-month review of unprecedented length that included 2,900 pages of transcripts, 923 exhibits and 50,000 pages of documentary evidence.
The Siting Board found that Cape Wind would meet an identified need for electricity and would provide a reliable energy supply for Massachusetts, with a minimum impact on the environment. The Siting Board’s approval of Cape Wind’s electrical interconnection was upheld by the Massachusetts Supreme Judicial Court.
Many of Cape Cod's well-known and wealthy residents, including Senator Edward Kennedy, are opposed to development of the wind farm. However, two public opinion polls have found statewide support for the project to be 86%.
As planned the Cape Wind project would included 130 wind turbines, capable of providing power for 400,000 homes at a cost of roughly $1 billion.
The project developer said construction could begin early next year, aiming for completion in 2011 or 2012.
Cape Wind is one of two planned offshore wind projects in the U.S. vying to be first in the water. Deepwater Wind off the coast of Rhode Island could begin construction in 2010
