Burning calories and generating electricity at the same time surely has to be one of the best answers to two of the biggest challenges faced by different societies across the globe: generating clean energy and tackling the obesity pandemic.
And this is what the folks at the Texas State (more…)

A reader who predicts a slow electric vehicles adoption curve writes:
Americans are addicted to not only to oil but also to driving. Most Americans see automobiles as freedom to do whatever, whenever they like. They do not like to be restricted by anything, including their vehicles. Early adopters are slightly different and are probably wealthy enough to have a (more…)

What if we, as individuals, could contribute to renewable energy simply by working out? Imagine hitting the gym, getting into your zone, achieving optimal heart rate and… putting electricity back onto the grid.
Not only is it a pretty cool concept, it’s becoming a reality.
All those Stairmasters, elliptical trainers, (more…)

We all know that walking is one of the most, if not the most, environmentally friendly means of transportation. What if you could help power the world around you just by walking? If you are picturing yourself like a hamster on a wheel you’ve got the wrong idea.
Hailing from the United Kingdom, Pavegen (more…)

Recently many states have chosen to deregulate their energy markets. This means that homeowners and consumers can choose who generates the power that they use. This is done in part to lower utility prices and to let competition drive the more or less monopolized market. At the moment there are 28 states that have deregulated either electricity, natural gas or both. In a (more…)

It seems counterintuitive, but a recent test by Washington state-based Inland Power and Light shows solar panels outperforming wind turbines by a factor of five.
Across much of the nation, and particularly the northern quadrant, wind seems to be perpetually present, blowing dust into our homes and barbecue smoke into our eyes.

Lighting is one of the biggest electricity guzzlers in a commercial building – 40% of it, to be precise.
One of the best ways to find out what to do to save electricity is using a web app that can provide data that can reveal how some retrofitting can benefit the building from an energy-saving and environmental point of (more…)

U.S. researchers say they have created a material that can generate electricity from waste heat with greater efficiency than other technologies. Scientists at Northwestern University placed nanocrystals of rock salt into lead telluride to create a material with the potential to capture waste heat from factory equipment, vehicle exhaust, and other industrial (more…)

Thinner and stronger than steel, graphene already outperforms all other known materials as a conductor of heat.
Graphene is a thin flake of ordinary carbon – a mere one atom thick, yet 200 times as strong as steel. Researchers at Columbia University’s Foundation School of Engineering said that “it would take an (more…)
