Chevrolet announced a five-year investment in 16 carbon-dioxide-reducing, ranging from biomass to wind turbines. Progress on the projects will be documented in videos over the next two months so the public can watch.

The automaker will spend up to $40 million on the projects to prevent up to 4.6 million metric tons of carbon dioxide, a little more than half of the goal of 8 million metric tons, from entering the air, Chevrolet said in a press release.

One project replaces natural gas with renewable biomass--mostly waste wood--to heat gardening plant greenhouses at Metrolina Greenhouse in Huntersville, N.C.… Read more

The small wind industry is about to enter a major growth spurt.

It is poised to grow from a $255 million industry in 2010 to $634 million industry in 2015, according to a recent Pike Research report.

The report attributes a growing interest and expected success in the coming years to the fact that small wind is currently more efficient and, therefore, cheaper on a cost-per-watt basis than solar photovoltaic cells. Because the return on investment can take as little as 5 years to 10 years, depending on area wind conditions, it offers an accessible option to small businesses, farms, … Read more

Think of it as carjacking for the Digital Age.

The increasingly sophisticated systems running a car may lead to new vulnerabilities, according to a study (PDF) released today from security software provider McAfee in partnership with mobile software provider Wind River and embedded security provider Escrypt. Those systems could allow hackers to take control of the car, track its location, and even access devices that are connected to it, including smartphones and tablets carrying valuable personal data.

The potential threat comes as hackers have increasingly shown a willingness to attack companies, government officials and agencies, and even Hollywood. Hacker groups … Read more

A weakening Hurricane Irene was downgraded this morning as it inched through New York City and headed into New England.

Irene was packing sustained winds of about 60 mph this morning as it moved up the Eastern seaboard at a speed of 25 mph, prompting the National Hurricane Center to downgrade it from a Category 1 hurricane to a tropical storm. The storm has been blamed for at least 11 deaths in six states, due mostly to car crashes and failing trees, and more than 4 million people have lost power due to the storm.

Despite the downgrade, the Federal … Read more

With Hurricane Irene making landfall in North Carolina, you're going to want up-to-the-minute information on the storm, especially if you live in the area or have relatives and friends who might be affected. Fortunately you can get an app for your iOS device that will give you all the latest information.

Note: Android users can find hurricane-tracking apps here.

There are several apps for iOS that let you track hurricanes around the globe. But the best hurricane-tracking apps give you up-to-the minute storm information, include radar and satellite images, and offer detailed push alerts for warnings and storm intensity changes. We found some very feature-rich apps for both iPhone and iPad and narrowed it down to one great app for each device.… Read more

COPENHAGEN--Denmark is known to many for its progressive architecture, functional design, and leadership in wind and renewable energy. (Not to mention its Michelin-starred Noma restaurant.) But given the country's green reputation, how much of Denmark's electricity would you suppose is provided by wind turbines? By renewable energy in general?

If you guessed 50 percent--or even 30 percent--you'd be wrong. And so was I--even after years of reading and writing about Denmark and its green technology.

Given my longtime intrigue with Denmark's progressive energy policy and stake in gas, oil, and wind power, I decided to visit … Read more

Typically, cost is the driving concern when choosing one renewable energy technology over another. But a pair of studies that consider land use give the edge to niche forms of solar and wind power generation.

Caltech researcher John Dabiri, a professor of aeronautics and bioengineering, this week presented results of a test that found that vertical-axis wind turbines have the potential to generate more power per square meter than the propeller-like, three-blade wind turbines. The key is that vertical-axis turbines can be placed close together without creating the type of wind disturbances that would sap performance of traditional turbines.

Dabiri … 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

The U.S. wind energy market took a hit in 2010 with a decrease in investment compared with 2008 and 2009.

That's according to the Department of Energy's "2010 Wind Technologies Market Report" (PDF) released yesterday.

The report measures investment in terms of how much wind energy capacity was built and connected to the national electric grid. About 5 gigawatts' worth of wind energy farms were installed in the U.S. in 2010, representing an $11 billion investment, according to the Department of Energy report. That represents a decrease in wind energy installations overall when compared … Read more
