A New York City roof covered in a white synthetic membrane was on average 43 degrees F cooler than surrounding black tar and asphalt roofs during times of peak heat last summer, according to a study by scientists from Columbia Read more…


The Niagara Tunnel Project in Ontario, Canada has reached a significant milestone with half of the tunnel now fully lined with concrete. When it is finished, the smooth concrete lining will ensure the efficient and uninterrupted flow of Niagara River Read more…


Last week New Energy Technologies went on the road to try out its MotionPower-Express system, which it calls the world’s first electricity-generating rumble strip. The test took place in the City of Roanoke, Virginia. The demonstration took place at the Read more…


The average human takes 3,000-5,000 steps a day. Seems like a lot, but most health experts would tell you to average 10,000 a day (but that’s a post for another time…). What if we could harness power from some of Read more…


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 Read 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 Read more…


Stanford University researchers have designed a rechargeable battery that uses the contrast in salinity between freshwater and seawater to produce an electric current, an innovation they say


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 Read 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 Read 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 Read 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 Read more…


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 Read 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 Read 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 Read more…
