Movies are definitely not the only things that look great in 3D, there is something else that has taken quite positively and effectively to being 3 dimensional. Solar Panels were designed in 3D in 2011 at the Massachusetts Institute of Technology and they are making waves again with new developments that might provide much needed…

US Places Tariffs on Chinese Solar Panels

In October 2011, SolarWorld and 6 other US manufacturing companies lodged a petition claiming that the dumping of cheap Chinese solar panels onto the market was unfair and prevented them from competing in the manufacture of solar panels.

Global increase…

The Benefits and Limitations of Modern Wind Turbines

Power From the Wind: Achieving Energy Independence by Dan Chiras

We’ve recently had articles on a ground source heat pump and on other alternative energy sources. Now here’s a guest post of the benefits of wind power. Wind energy is the process where wind turbines are converting kinetic energy from the wind into mechanical energy, which again is converted into electricity by a generator. Many…

Solar Protest Action in Australia

Members of the solar sector in Australia have pronounced the 2011 Federal Budget, released last week, as “disappointing”. But Australian’s aren’t taking disappointment lying down. The Solar Last Chance Rally today is a response to the NSW Government permanently closing down their Solar Bonus Scheme (notably started by the previous government), and announcing last Friday…

Solar Power Boosts Home Values

A recent study in California found that having a rooftop solar power system installed significantly increased the value of homes. No surprise right? But the interesting thing was that the sale value of the homes with solar power increased by about the cost of installing the system – even though the original home owner had…
