In a unanimous vote, the Public Service Commission (PSC) recently cleared the way for Alliant Energy's Wisconsin utility to construct a 200 megawatt (MW) windpower plant project in southern Minnesota. Once operational, the Bent Tree project, costing upwards of $450 million, will be a productive source of renewable energy that will provide lasting benefits to Minnesota's economy and environment. Since it will be Alliant's Wisconsin customers who foot the bill, however, it is reasonable to inquire whether the current utility practice of outsourcing renewable energy production to other states is a good thing for Wisconsin's economy.
Solar powered attic fans are cool! Having worked in attics for many years installing solar water heaters I know all too well how hot they get. I've measured 140 degrees F! Most homes have manual roof vents, which allow some nominal air movement, but they can't keep up with the sun pounding down all day.
My long and winding path through the selection of the best heating and cooling system began six months ago and culminated with the selection of a geothermal system, which is right for us for so many reasons.
Wagner & Co is a leading provider of integrated solar thermal and solar electric systems solutions. Off -grid solutions were among the first solar electric applications and yet also developed into a particularly innovative field, where new technologies, approaches and combinations are being tested. Off-grid - or "Island" - systems, as they are also called, can be found in many new infrastructure projects.
You can go to Shanghai for a vacation, buy two or more of these cars, one for your wife and one for yourself, and one for each of your kids, have them shipped home and still spend less money than if you bought a car at home.
The Dow Jones Industrial Average recorded its best month in nearly seven years, posting an 882-point boost since Friday, July 3. In fact it was the best July for Wall Street in twenty years. Gains for the week for the Dow and NASDAQ were meager however, with both gaining less than a percent. The 20SSI decreased 5.8% from last week's close but the net gain since July 3 was nearly 22 points.
On April 30, 2009, Mayor Michael Nutter unveiled the first of 500 BigBelly solar-powered trash compactors and 210 companion single-stream recycling units to be installed throughout Center City Philadelphia. The solar compactors save time, money and fuel by reducing demand for collection trips. The compactors are also smart trash receptacles: each unit sends a wireless signal to alert staff when it is full, so managers can optimize collection routes in real time based on data from every machine in the field.
While the United States is rich in renewable resources for the production of green electricity, expansion and modernization of the North American power grid will be required to transmit that power to where it is needed.
AAER Wind Energy have partnered with Fuhrländer to manufacture the Fuhrländer 1.5 MW wind turbine on a license in Canada.

One university's quest to revolutionize the built environment.
Much is made these days of attaching the word green to products and/or buildings as a means of promoting a product or building in the market place even though the greenness or sustainability may be tenuous at best. I believe it is timely to make clear and to discriminate as to just exactly what do we really mean when we refer to a building as being green as well what kind of green are we referring to. We are all not talking about the same green therefore I wish to examine what I see as the main categories of green.
In 2005 I swapped a perfectly good town house on 198sq m of land for 5400 sqm of land of valley Grassey Forest vegetation. This block some 22 km from the centre of Melbourne Australia (Australia's 2nd largest city) was going to be perfect for my growing family.
