Integrating solar cells into building materials could make solar power more attractive to homeowners. Seamless solar: The solar system shown here (darker panels) integrates thin-film solar modules directly into a metal roof. Such systems offer cost savings in labor and materials and blend well with buildings' designs. Credit: EnergyPeak In an effort to promote the adoption of solar technology, United Solar Ovonic of Auburn Hills, MI, has teamed with a major roofing company to create a metal roof system that generates electricity from sunlight. The partnership offers seven different prefabricated systems, ranging in capacity from 3 to 120 kilowatts. Tests show that the solar roof panels are rugged and can withstand winds in excess of 160 miles per hour.

Will Stewart has a guest post up at The Oil Drum on passive solar design techniques - Passive Solar Design Overview - Part 1. Also, at TOD, a post on the Passivhaus standard from another long-time commenter, marjorian - US Housing and the Passive Home Standard. Passive solar refers to the design and placement of a building to enable solar heating without the need for sensors, actuators, and pumps, in contrast to active solar, which utilizes pumps/blowers, sensors, and logic control units to manage collection, storage, and distribution of heat. The two techniques are not exclusive, however, and can work together effectively. As solar radiation (insolation) is a diffuse energy source, and not at the beck and call of a thermostat, passive solar design techniques are at their best when combined with other related methods, such as energy efficiency (insulation, weatherization, building envelope minimization), daylighting, passive cooling, microclimate landscaping, and a conservation lifestyle (i.e., temperature settings, raising and lowering of insulated shades, etc). Most of these topics will be covered in other articles, though passive cooling will be addressed in this series, which is intended as an overview, as a complete engineering treatment on passive solar design would require several dozens of articles.

CNN reports that Obama is planning an economic stimulus package based on energy efficient buildings and improved internet access - Obama outlines initiative to create 2.5 million jobs. President-elect Barack Obama on Saturday outlined some of his plan to create 2.5 million jobs by 2011, and said he will push for immediate action by Congress when he takes office in January. Obama wants to make public buildings more energy-efficient, repair roads and bridges, modernize schools, increase broadband access and ensure that health care professionals have access to the latest technology. "Our government now pays the highest energy bill in the world," he said in the weekly Democratic radio address.

More than 100,000 people attend; a testament to the popularity of sustainable building and renewable energy in the region. by Michael Fell Wels, Upper Austria [RenewableEnergyWorld.com] Last week saw the return of the World Sustainable Energy Days conference which is held every year in Wels, Upper Austria. Taking place over three days (plus a day of site visits), the conference has three main streams: the European Pellet Conference, the European Energy Efficiency Conference and Regional Biomass Action Plans. Austria is an apt location for the conference - along with Sweden it is well known as one of Europe's biggest users of pellet technology - and as the final remnants of this year's snow melted away it is plain to see why. With cold winters and real enthusiasm for efficient and sustainable building, the demand for renewable heat is strong. The country is also highly forested, providing ample raw material for pellet production in the form of sawdust and wood shavings from sawmills (along with other biomass waste).

Straw bale construction uses straw to build residential and commercial structures that are energy efficient and eco-friendly. It continues to gain adherents because of its use of natural building materials,

What began as a project to make the company's new headquarters as energy-efficient as possible blossomed into an endeavor that created the first net-zero electric commercial building in the country. Net zero means that the building produces all the elec

DONG Energy, E.ON and Masdar have announced that they will invest EUR 2.2 billion (US $3 billion) in building the first 630-megawatt (MW) phase of the London Array offshore wind farm in England's Thames Estuary. The wind farm is set to be build the world's largest offshore wind farm. The consortium hopes the first phase of 630 MW will be completed and generating in 2012. The first phase will consist of 175 turbines. The announcement comes after the UK Government's recent proposal to increase its support for offshore wind power. The partners are satisfied that the project is now financially viable and are now keen to push ahead with construction and to produce the first renewable power in 2012. Onshore work is now due to start in the summer, with offshore work due to start in early 2011.

The article "Renewable energy potential" (Work&Money, Editor's Choice, June 7) provided interesting and useful information. Now it is time to begin to use more renewable energy in North Carolina. One of our electric utility companies should develop a pilot project in one of the high-wind areas off the North Carolina coast. This energy could be used to provide some power to Elizabeth City, Manteo or any other city located on the northern part of our coast. Our electric utility companies have many intelligent engineers who could use new technology to build wind turbines that can withstand strong storms. If other states in the Northeast can build wind farms off their coasts, then North Carolina can surely do the same.

After completing a building, or tearing one down, there are often collections of small left-over materials, as well as entire pieces that do not qualify for a refund at the lumber yard for some reason.

The state began its pursuit of offshore wind generation Tuesday, a move that could lead to building 400-foot-tall turbines off Ocean City. The Maryland Energy Administration asked wind developers to express their interest in building industrial-size windmills a dozen or more miles off the state's 31-mile Atlantic coastline. At the same time, the energy agency said it is launching a study to gauge the economic viability and environmental impact of such a project.

A property developer is one who takes a piece of land and finds the best possible use for it for a client. Perhaps a client is looking to buy a piece of land to build a home. The property developer will find the right plot, lot or land to build the home as specified by the client.

The Canadian Wind Energy Association (CanWEA) released its strategic vision for wind energy development during its 24th Annual Conference and Trade Show taking place this week in Vancouver. The plan, Wind Vision 2025 - Powering Canada's Future, cites rapidly rising energy costs, reducing the country's environmental impacts caused by current electricity generation, the need to quickly build more electricity generation to keep up with rising demand and the need to build a more robust transmission system a key drivers for the adoption of wind technology.

I used to be a strict modernist; my role at TreeHugger was to demonstrate that green design could be wonderful and cool and I filled the site with all kinds of modern houses with some claim, often weak, for being green. Those houses became less common on the site in recent times, as I worried more about house size, the appropriateness of single family dwellings on big suburban lots, and trying to reconcile my love of clean, modern design with my concern about the use of fossil fuels or building materials that cannot be maintained in a world made by hand.

Biologists and botanists are particularly excited by the project; they believe that close study of the flora and fauna in this artificial environment will improve our understanding of the delicately balanced ecological systems of the earth. But the many applications of Biosphere two are not just earth-bound; lessons learned from the project could have profound implications by paving the way for the creation of future colonies in space.

Green building of the week from Inhabitat is this vertical farm proposed for Vancouver - Amazing Skyscraper Farm for Vancouver. I'll believe vertical farms work when I see it, but I'd like to see one tried, purely for the sake of showing how successful they can (or can't) be. Vertical farms are one of our favorite future-forward concepts for creating sustainable cities. Providing locally-grown produce and food will not only help us reduce our carbon emissions significantly, but also help us become healthier. Romses Architects recently came up with an amazing concept for a vertical farm in Vancouver as part of the City's 2030 Challenge. Complete with a tower for growing fruits and vegetables, a livestock grazing plane, a boutique dairy farm, commercial space, transit lines, renewable energy and more, the Harvest Green Tower has the potential to be a food growing, energy producing, living, breathing sustainable transit hub.

What is the best evidence that concentrated solar thermal power (CSP) aka solar baseload is indeed a core climate solution with big near-term - and very big medium-term - promise? One of the country's biggest companies, Lockheed-Martin, with 2008 sales of $42.7 billion, has jumped into the race to build the biggest CSP plant with thermal storage.

Being a green carpenter can be realized through prioritizing green building measures. Ecological construction uses renewable and sustainable resources and energy-saving tools.
