The route between La Paz - one of the world’s highest administrative capitals - and El Alto, Bolivia is one of the craziest commutes around. The cities are only a few miles apart, but it takes over an
On April 18th, the Oregon Institute of Technology in Klamath Falls celebrated the completion of two major renewable energy projects, making it the first university in North America to generate all of its
Scientists in South Korea have come up with a way to use the mechanical energy of flowing water as a sustainable energy source. The research shows how the energy potential of flushing toilets can be
Josef Stöger's Bavarian Forest National Park Treetop Walk Josef Stöger's winding timber walkway isn't just in the shape of an egg--it's also the longest treetop walk in the world! Located in Germany's
Skincare company Foreo has an illuminating idea for saving energy: just increase the moon’s reflectivity to make the night sky brighter. Think of all the electricity savings if we didn’t have to power
Buried at the very bottom of a fact sheet released at yesterday's White House Solar Summit is a striking statistic: "Every four minutes, another American home or business goes solar, supporting workers
2013's government shutdown didn't stop the United States Department of Energy (DOE) from moving forward on a range of initiatives to ramp up renewable energy, promote energy efficiency, and combat
Here's some good news on the climate change front: Greenhouse gas emissions in the United States fell nearly 10 percent from 2005 to 2012 and dropped 3.4 percent in 2012 alone, according to the U.S.
A new study from the University of Delaware finds that high-altitude wind turbines tethered to the ground like kites could potentially generate enough clean, renewable electricity for the entire world.
Solar energy forms the crux of the office building, which will use solar cells, heat exchangers and heat pumps to meet most of the building's electricity and heating needs. Rising from the fjord in the
With 250 days of sunshine a year, Mongolia's potential for solar energy is vast but mostly underutilized. That's beginning to change though - a new government sponsored initiative aims to equip
The table’s clear orange glass work surface rests on triangular wooden legs. Inside the glass panel is a dye-synthesized solar cell that creates energy using the same mechanism as plants-photosynthesis.
There are companies who talk about going green, and companies who do something about it. This week, for the 206th time, IKEA proved that it belongs in the latter category. The popular home furnishings
The Rio Branco 12 office tower on Rio Branco Avenue will have 21 floors. Currently undergoing an urban revitalization, Porto Maravilha is slated to become a new urban and commercial district with over 5

The 7-story building features triple-glazed windows, a high level of insulation, and it's practically airtight. The photovoltaics mounted on the roof produce energy primarily for the building, although
According to the Bureau of Ocean Energy Management, if you utilized just 1/1000th of the energy potential available in the Gulf Stream in the Atlantic, you could supply Florida with 35% of its
When we first spotted this crazy picture of a Prius driver hitching a free energy ride on San Francisco's MUNI power lines, we couldn't believe it! Equipped with a giant trolley pole, the Franken-Prius
Tiny English Village Blocks Giant Fracking Operation, Announces Plans to Build Community-Owned Solar Power Plants
Normally, the village of Balcombe, West Sussex is just another picturesque spot in a valley where nothing really happens. But when Cuadrilla Resources--the UK's fracking pioneer--announced plans to do
Researchers at Oregon State University just made an energy breakthrough that could cut the cost of solar energy while also drastically reducing the carbon footprint of manufacturing solar materials. OSU
Practically everyone knows that LED and fluorescent light bulbs are better than inefficient incandescents, but many consumers just can’t resist the familiar shape and soft, warm glow. Philips plans on
Windmills offer a great way to harness renewable energy, and they’ve been around for almost two centuries - but who says that’s the only way you can catch the wind? Festo, a supplier of automation
