In November, I visited Washington, D.C. to discuss the importance of energy security, which includes the use of alternative fuel like natural gas. I did so because the nation has the ability to harness newer, cleaner, domestic energy sources.
Nissan's Leaf has a long way to go to expand beyond its status as a niche commuter car. Sales have been underwhelming, even with cheap lease offers, leading some to declare the Leaf an overpriced, impractical flop.
The world produces approximately four billion metric tons of food a year, but approximately 1.2 to 2 billion tons go to waste, according to a report from the Institution of Mechanical Engineers issued Thursday.
Wind power is free, which is why German engineers have been experimenting with a device they termed SkySails. They’ve proved that inflatable kites can actually haul freighters across the ocean. This mirrors research conducted over 20 years ago by a Japanese firm. Those who say that sails aren’t a new emerging technology should be careful, since the efforts are actually becoming popular with scientists.
One of the best antidotes to climate change is rarely discussed. Buildings in the U.S. generate 40 percent of the global warming gases and use 70 percent of the electricity. If we do things right, we can cut energy use 90 percent in new buildings and 70 percent in retrofits while improving comfort and health. In new buildings, this may be done at no cost if integrated resilient design strategies are adopted. We can improve comfort, productivity, how students learn, health and security, often at no added cost.
A report from the Federal Energy Regulatory Commission's Office of Energy Projects says that, in 2012, the capacity for renewable energy electrical generation accounted for almost 50% of all new installations for energy projects in the United States. ...

Global green tech investments tumbled in 2012, but a few sectors, such as water and agriculture, attracted a greater interest from investors than the year before, according to market data released by the Cleantech Group on Thursday.
The Chevy Volt already ranks among the greenest vehicles in the world, but Chevrolet and General Motors have found a way to make the plug-in hybrid's battery serve a purpose long after it's off the road.
Last week the auto manufacturers and The ABB Group unveiled a back-up generator powered by spent Volt batteries. Even though the Volt battery is guaranteed to last eight years on the road, its capacity for alternative use extends long beyond use in the car.
The ABB Group's off-grid structure uses five former Volt batteries to provide 25 kilowatts of power, or enough energy to power three to five average American homes for two hours.
