Case Study: Eagleyew – A High Efficiency Natural Building on Vancouver Island, B.C., Canada

The Story of Eagleyew: A High Efficiency Natural Building on Vancouver Island, B.C., Canada I’m pleased to say that I have been building Natural Buildings for a number of years now. My work has taken me up and down the West coast of North America, with a focus in the Pacific Northwest. I’ve been calling Vancouver Island home for the last three years, and have had the pleasure of working on some amazing Natural Homes in the area. From cob…

Energex: Rooftop Solar Is Destroying Our Business Model

Joining the rest of the utility power companies, Energex, a Queensland electricity network operator, believes that rooftop solar is destroying its traditional business model. The concept of generating power at a centralized location, and then distributing it to thousands of people via an electricity grid was created to benefit from economies of scale, while keeping the source of power plant pollutant and noise emissions out of residential areas. However, such benefits of scale apply only to fossil-fueled and nuclear power…

New Building Code For Energy Efficiency

The International Code Council considers a new building code for energy efficiency which improves the energy efficiency of buildings, providing buildings with an efficiency score. The new code should save $300 to $850 off utility expenses annually. Don’t forget that it mitigates the problem which makes you have to choose between getting hot and sweaty, or paying more than you can afford for energy. I’m sure that some home buyers would like to know the energy cost of the houses…

Spray-On Solar Cells At A Lower Cost

Relatively inexpensive, easy-to-manufacture, nanoparticle-based solar cells can be created with materials that are abundantly common throughout the Earth’s crust, according to new work from researchers at the University of Alberta. The new nanoparticle-based solar cells — which could be mass-manufactured using simple methods, such as roll-to-roll printing or spray-coating — are possible thanks to a new type of nanoparticle designed by the researchers. The researchers think that the new design/discovery — which according to them has been several years in…

International Indoor Soccer Arena Switches To Solar To Save Money

The International Indoor Soccer Arena (IISA) in Albuquerque, New Mexico, has gone solar! While — to be honest — this is the first time that I’ve ever heard of the arena, it’s certainly still good news anytime businesses switch to renewable energy sources — good news both for the environment and also for the business’s bottom line. As anyone who has ever been involved in business knows, overhead expenses for things such as electricity often constitute a large proportion of…

Can Solar Energy Help Save Greece?

What happens to renewable energy programs in a country that gets whacked by a full-scale debt crisis, like the one that struck Greece beginning in 2009 — do the programs whither and die in the winds of austerity? And how do people view such programs when many of them can’t afford to heat their houses?

Arizona Desert Hosts World’s Largest “Net-Zero Energy” Building

In the Arizona desert lies the world’s largest “net-zero energy” building. It is the Phoenix Regional Office of DPR Construction. It was given this certification by the International Living Future Institute (ILFI). Located on the corner of 44th and Van Buren, the energy efficiency transformation took 10 months to complete. It is the largest building in the world to receive such a certification from this particular institution. It was originally a windowless concrete block building from the 1970s which was aging. It was…

Making Solar Energy Affordable: The Positive Sides of Copper Doping

In order to make solar energy widely affordable scientists and engineers all over the world are looking for low-cost production technologies. Flexible thin film solar cells have a huge potential in this regard because they require only a minimum amount of materials and can be manufactured in large quantities by roll-to-roll processing. One such technology relies on cadmium telluride (CdTe) to convert sunlight into electricity. With a current market share that is second only to silicon-based solar cells CdTe cells already today are cheapest in terms of production costs.
