In a classic pairing of IT and renewable energy, an IBM supercomputer will optimize placement of wind turbines to improve performance.

IBM and Danish wind turbine manufacturer Vestas yesterday announced that the Firestorm supercomputer will analyze petabytes of data to maximize energy output of Vestas turbines.

The supercomputer crunches through weather reports, moon and tidal phase, sensor data, satellite images, and deforestation maps to generate the best placement of turbines, IBM said. Once installed, Vestas engineers will use the software to predict future performance and figure out the best time to do maintenance.

Predicting energy output of turbines is vitally … Read more

Chip giant Intel procured over 1,493 gigawatt-hours of renewable energy in 2010.

That's according to a survey of over 1,000 companies that was conducted by Bloomberg New Energy Finance in conjunction with wind turbine giant Vestas Wind Systems.

The index developed from this new survey is called the Corporate Renewable Energy Index (CREX). (For a PDF of the white paper on the survey, click here.) For its inaugural release the CREX released rankings of companies based on the amount of renewable energy they procured both in 2009 and 2010.

For 2010, the top five companies with the largest renewable electricity procurement were: Intel, clothing retailer Kohl's, Hong Kong electric company CLP Holdings, supermarket chain Whole Foods Market, and the Dutch telecom Koninklijke KPN.

For 2009, the ranking was Deutsche Telekom, Intel, PepsiCo, BT Group, and clothing retailer Kohl's.

Keep in mind that no one is suggesting these companies are gleaning electricity directly from local solar or wind farms. While some companies do directly support renewable-energy projects, over 80 percent of the renewable electricity procured by the companies surveyed was purchased in the form of renewable electricity credits (RECs).

And while Intel procured the most renewable electricity in 2010 at over 1,493 gigawatt-hours, on a percentage basis it's actually Kohl's that wins. In 2010 the retailer purchased so many RECs, it statistically can say it garnered 100.4 percent of its energy from renewable sources.

In conjunction with the CREX, Vestas also had TNS/Gallup conduct a survey on wind energy procurement in particular.

When it comes to wind, Whole Foods tops the list. The supermarket chain gets 100 percent of its electricity from wind energy, followed by North American bank Toronto-Dominion Bank at 78 percent, and software giant Adobe Systems at 65 percent, according to the Global Consumer Wind Study 2011.

More statistics and rankings of companies by industry can be found in Appendix D (page 30) of the CREX white paper (PDF) released by Bloomberg New Energy Finance and Vestas.… Read more

Call it a "wind-win" opportunity: there's a new push on for a "WindMade" certification label for U.S. companies, services, and products.

The announcement yesterday (on Global Wind Day) in New York by a group of organizations marks the start of a two-month development period. But the first draft of the standard allowing the use of the WindMade label requires that a company source at least 25 percent of its electricity from wind in order to qualify.

The idea for a WindMade label was originally proposed in January at the World Economic Forum in Davos … Read more

The development of a "stealth" turbine blade, based on military technology, may help overcome the problem of wind farms interfering with aviation radar systems, its developers said.

The issue of turbine blades confusing radar operators accounts for around half the objections to wind farm planning applications in Britain.

Now, Vestas Wind Systems is experimenting with stealth technology, developed to help warplanes escape notice, to reduce a turbine blade's radar signature--the size of the blip it makes on an air traffic controller's radar screen.

"These tips of the blades travel at about the same speed as … Read more

With politicians pushing adoption of renewable energy in the United States and Europe, the last few years have seen a surge in plans for wind farms--both on land and sea. But wind power isn't viable everywhere--and prime coastal spots are often already developed.

So some wind-turbine makers are shifting their focus toward building bigger wind turbines that can harvest the lower-speed winds that are more readily available. This next generation of wind turbines is no small matter: their rotors have a diameter the size of a football field.

In general, wind turbines get more powerful and efficient with taller … Read more

Want some turbines to build a wind power park? Get in line.

High demand--coupled with the engineering challenges of building turbines that can extract hundreds of kilowatts or megawatts of power from the wind--has created a shortage. Wind park developers, thus, are being forced to jostle their plans and supply line relationships to keep projects on track.

If you order now, you might not get turbines until late 2009 or later.

"There has been a backlog for a significant period of time. The lead time is around a year to a year and a half," said Myke Clark, … Read more

A new kid on the block named Vestalife is set to roll out a new iPod speaker dock at CES named Ladybug. Realizing that no self-respecting man will ever buy something called a Ladybug, Vestalife is partnering with Element Skateboards to create a limited edition version, clad in black, chrome, and skulls.

The Vestalife Ladybug includes two 1.5-inch tweeters that fold over the face of your iPod, making a tiny sonic cocoon for your precious MP3 player. The back of the Ladybug houses a single 3-inch sub, along with an auxiliary input, USB port, AV output, and an external … Read more
