A new 42-floor London skyscraper will be the world’s first building to incorporate wind turbines in the design, an innovation developers say will generate 8 percent of the building’s electricity needs.

The Strata Tower, a 408-unit apartment building scheduled to open in July, will be topped with three 19-kilowatt turbines — each with five 29.5-foot blades designed to suck wind from various angles and accelerate it through tubes, generating as much as 50 megawatt-hours of electricity annually.

It will also generate about £16,000 to £17,000 annually through the nation’s new feed-in tariff, the developers say. (more…)

(Reuters) – British Columbia has given the green light to 19 private-sector clean energy projects that will generate enough power to supply nearly 218,000 homes in Canada’s Pacific Coast province.

The approvals, announced late on Thursday by BC Hydro, the government-owned electricity utility, mark the first phase in the provincial government’s long-delayed push to generate more green power.

Fourteen of the 19 proposals are 14 run-of-river hydroelectric projects, in which river water is diverted through turbines to produce power without the use of dams. The remainder are wind power projects. (more…)

Wind power generation in Texas is growing so quickly that it is testing the limits of the state’s electrical grid.

The state set a record on March 5 when wind turbines generated 6,272 megawatts of energy, or about 19 percent of the electricity on the state’s main power grid.

That peak far exceeded the 6.2 percent average for wind power in Texas, whose 9,410 megawatts of total wind capacity make it the nation’s wind power leader.

But wind power’s growth poses a critical challenge for the state’s booming wind industry, which includes a 180-megawatt wind farm completed last fall near Corpus Christi in South Texas. (more…)

The most surprising thing about the inaugural ARPA-E summit, held this week outside Washington D.C., is that the conference hall was full of losers. They were inventors, scientists and entrepreneurs who had applied for funding from the U.S. government’s exciting new energy-research organization but had been shot down.

The Advanced Research Projects Agency – Energy received 3,500 proposals, but only accepted 37. That leaves room for some compelling also-rans.

As a consolation prize, some of the most credible finalists got booth space in the exhibit hall. The most visible were those with ambitious plans for “kite power” — harnessing the powerful and consistent winds that blow high off the Earth’s deck.

Kite energy is way out there, both physically and in the public mindset, and it can be a hard sell, even to an agency like ARPA-E that funds risky projects. Who wants to put their money on the line for a four-rotor helicopter the size of a 747 that’s suspended several kilometers in the air? (more…)

Wind turbine technology has become a fully commercial venture, but the recent rapid growth of the wind industry has strained its supply chain to meet demand in a timely manner. Furthermore, unexpected component failures, especially electronic controls, gearboxes, generators, and rotor blades, have driven up operations and maintenance costs.

During the course of the research for a new report just published by Wind Energy Update, it ultimately became clear that reliable and verifiable data on wind industry operations and maintenance cost trends is quite rare. In fact, there are no current widely available data sets illustrating these wind industry costs.

Proprietary research, reviews of scarce secondary sources and anecdotal evidence obtained through confidential interviews with wind industry owners and operators and component suppliers suggest that operations and maintenance expenses are double or even triple what was originally projected, particularly with the latest class of multi-megawatt machines now permeating the global wind market.

Four Democratic U.S. senators have asked the Obama administration to stop investment in wind power and other renewable energy projects until the government ensures that the projects primarily use U.S. labor and materials.

The senators, led by U.S. Sen. Charles Schumer, introduced legislation requiring that economic stimulus funds only be spent on clean-energy projects that use materials made in the United States and that create a majority of jobs in America.

The British government will introduce legislation that would tie new, subsidized loans for energy efficiency to a house, rather than a current owner, a move that could make energy retrofits far more affordable for most homeowners.

Energy and Climate Secretary Ed Miliband said the new legislation would enable homeowners to take out long-term loans at lower interest rates and thus encourage homeowners to make energy-efficiency improvements that they might otherwise not have made had they planned to sell their houses in a few years.

By 2020, the European Union will meet its goal of generating 20 percent of its electricity from wind, solar, and other renewable sources of energy, according to the European Wind Energy Association.

The group said that 14 of the EU’s 27 member states will meet the 20 percent goal, eight will exceed it, and five will fall short, though only by one percent.

Wind power capacity grew by 31 percent globally in 2009, with the steepest rise occurring in China, according to a new study.

About 37.5 gigawatts of capacity were added last year, boosting the total capacity worldwide to 157.9 gigawatts, says the Global Wind Energy Council, an industry trade group based in Belgium.

The growth occurred despite the weak global economy as major nations made renewable energy a priority of their economic stimulus plans, said Steve Sawyer, the council’s secretary general.

This post comes from Rev. Canon Sally G. Bingham, the founder of the San Francisco-based Interfaith Power & Light, a national campaign with affiliates in 30 states. The group is organizing the Valentine’s Weekend Preach-In on Global Warming.

Valentine’s Day typically conjures up images of roses and sweets for our loved ones, a time when we recognize the many virtues of romantic love. Yet this coming Valentine’s Day, leaders of communities of faith throughout the United States will be bringing forth a different kind of love — a deep, abiding love for God’s creation and our neighbors now threatened by the calamity of global climate change.

Hundreds of congregations of many faiths have signed up for a National Preach-In on Global Warming on Valentine’s Day weekend. We are showing our love for the poor, disadvantaged and most at-risk peoples and creatures of the world on this traditional day of love.
