There is a dearth of tech products that can also double as accessories for fictional serial killers. If Hannibal Lecter was as into jogging as he was into human consumption, he would have definitely been sporting the Aire mask to power his iPod.

The idea behind the mask it that your breath charges your small electronics. The mask contains small wind turbines that convert your huffing and puffing into renewable power.… Read more

President Obama has called for an "all of the above" energy strategy, ranging from taxpayer funding for electric vehicles to more drilling for oil and natural gas. The goal is to get a greater contribution from domestic renewable-energy sources, such as the sun and wind, yet maintain cheap domestic energy from traditional fossil fuels.

"We're not going to be able to just drill our way out of the problem of high gas prices," Obama told a North Carolina crowd on March 7. "If we are going to control our energy future, then we've … Read more

In the old days, renewable energy was the best option available. Then it became a social statement. Now with fits and starts, it's creeping toward the mainstream.

To give CNET readers some perspective on renewable energy, we've assembled a slideshow on renewable energy through the ages, its present form, and some ideas as to where it's going.

The history of using the wind, sun, and water reaches back to antiquity. But what's remarkable about many renewable-energy technologies being pursued today--solar, wind, geothermal, and bioenergy--is that today's product ideas often have roots in research begun after … Read more

Families and retirees come to New Mexico to chill in the sun; aliens come to crash-land their ships; scientologists come to build secret compounds and prepare to visit the aliens; the government comes to hide the crashed alien ships and blow stuff up; and studios come to make movies about all of the above. Now, a private company is coming to build a 20-square-mile ghost town of the future.

D.C.-based Pegasus Global Holdings is planning to build the model city to test new and up-and-coming technologies such as smart grids, renewable energy, intelligent traffic systems and next generation Wi-Fi. The company says the huge facility, dubbed "The Center," would likely be located somewhere near the Albuquerque or Las Cruces metro areas, giving the company access to multiple Interstate corridors, nearby national labs, universities, and military installations.… Read more

Dow Chemical today announced a joint venture to produce ethanol and plastics from sugar cane, a step toward sourcing renewable feedstocks for chemicals.

The joint venture between Dow Chemical and Japanese industrial conglomerate Mitsui will initially produce ethanol from sugar cane, which will then be used as a feedstock to make plastics. Financial terms of the venture were not disclosed.

The companies project to start construction of the operation, which they say will be the largest facility for making biopolymers from ethanol in the world, in the third quarter this year. Dow Chemical expects to make plastic replacements for flexible … Read more

DEARBORN, Mich.--The 2011 Forward with Ford conference here last week gave outsiders a look at Ford Motor Company's push to makes its cars greener.

Actor and activist Ed Begley, Jr. joined Ford Motors' Sherif Marakby to discuss the company's ongoing efforts to electrify cars. Ford develops three levels of greener vehicles--hybrids (like the Ford Fusion hybrid), plug-in hybrids (like the Ford CMAX Energi), and all-electric vehicles (like the Ford Focus Electric). Ford is hip to the 2011 Maritz Research study reporting that 42 percent of all consumers consider fuel economy "extremely important" when buying a new vehicle. So, Ford delivers 12 vehicles that get 40 mpg or higher in EPA highway testing. … Read more

The U.S. wind industry is growing again after taking a big step backward last year.

Yet turbine makers and wind farm developers are finding few reasons to celebrate as the clean energy source struggles to secure long-term government support while facing stiff competition from cheap natural gas.

Once the world's top wind market, the United States ceded that mantle to China last year as a weak economy halted its growth and cut new installations to half of the 10,000 megawatts of capacity built in 2009.

Since then, business has picked up, but not for the reasons the industry would like. Energy demand is still tepid due to a gurgling economic recovery, and the low cost of natural gas is keeping power prices low.

Pricing in long-term power sales contracts signed by wind developers has fallen 30 percent in the last two years and will fall further this year, according to IHS Emerging Energy Research.

Currently, the market is being shepherded by developers who are scrambling to put turbines in the ground ahead of a 2013 expiration of lucrative federal tax credits for wind. Beyond that date, the industry's fortunes are hazy. … Read more

Prime Minister Naoto Kan said today that renewable energy will be a key pillar of Japan's energy policy after the world's worst nuclear crisis in 25 years and that its nuclear policy must be reviewed from scratch.

The massive earthquake and tsunami on March 11 knocked out cooling systems at the Fukushima plant in northeast Japan, and the prolonged crisis could hamper Japan's efforts to reduce its use of fossil fuels. The plant is still leaking radiation.

"The current basic energy policy envisages that over 50 percent of total electricity supply will come from nuclear power … Read more

Renewable sources such as solar, wind, and hydropower could fulfill almost 80 percent of the world's energy demand by 2050 with the right policies, according to a U.N. report which won backing from governments today.

The 26-page study, by the U.N.'s Intergovernmental Panel on Climate Change (IPCC), broadly matched a draft written by scientists. It was approved by government delegates at talks in Abu Dhabi.

Environmental groups hailed the report as a guide to the shift from fossil fuels to combat climate change, a process set to cost trillions of dollars. But they said some draft … Read more
