Congratulations, kilt-wearers, and descendants of William Wallace! Your country’s seas are about to become the proud guardians of the world’s largest floating wind farm.
The idea of peak oil has haunted us for decades. I say haunt because the concept that sooner or later we’d run out of the stuff has contributed to some terrible public policy in the United States.
According to the Center for Climate and Energy Solutions, about 2.3 percent of America’s power is generated by wind. But wind power is becoming wildly popular all over the world. What would happen if a company put up so many wind turbines that they actually changed the climate on Earth? That’s the subject of this…
In the twentieth century, oil was black gold. But as we march deeper into the twenty-first century, we could have a lucrative new fuel on our hands. One that’s blue-green and sometimes a little smelly. It’s found in wastewater, but it’s capable of powering jets. It’s algae.
As in, holy crap, we knew solar was getting cheap, but wow. Among energy afficionados, the precipitous decline in the price of solar cells is called "The Swanson Effect." And no – not after that Swanson.
Looking for an alternative to turbines for capturing wind energy, Belatchew Arkitekter has proposed adding a hairy addition to Stockholm's Söder Torn. It would serve as more than an architectural toupee, capturing energy through the movement of all those tiny straws.
Brazil's Santa Rita do Sapucaí prison has found a new source of alternative energy: its own prisoners. The prison has offered to shave time off of prisoners' sentences if they'll charge batteries using special bikes and their own two legs.
It appears that brown is the new green. The Denver Zoo has decided to make use of all that primo animal poop that comes out of its residents and convert it into fuel. Now you can tour the zoo (and enjoy a frozen margarita) with the aid of this poo-power.
Are hamsters the next step in resolving our energy crisis? A group of rodent transit enthusiasts decided to test their new invention, the Hamster-Powered Submarine (HPS), and film the vehicle's maiden voyage.
Splitting water into hydrogen and oxygen is generally considered a fantastic way to get a renewable power source. The problem is how exactly you go about splitting the water. Current methods require some power input in order to kickstart the reaction, reducing its effectiveness as a sustainable power source, since…
Biofuels are made from carbohydrates and fats in corn and other feedstock. This is a wasteful process because it leaves behind all the protein, a far more abundant substance. As a result, one of the big questions for alternative energy researchers is how we can pull biofuel from protein. Especially because proteins…
Wind is a clean, renewable energy source, but there isn't nearly enough of it down here on the ground. But high in the sky, there are furious jet streams of powerful wind just waiting to be harvested by floating turbines.
John Denver proclaimed it "almost heaven", but a group of geoscientists are implying it's a little more like the opposite. Most of the rest of the world doesn't think of West Virginia as a hot spot, but it is.
Biofuels like ethanol could help us reduce our dependence on fossil fuels, but growing crops for ethanol involves using up huge swaths of valuable farmland. Now we might have a solution - thanks to some re-engineered yeast.
There's electricity in the air all around us, formed as water vapor comes into contact with dust particles. For centuries scientists have dreamed of tapping into this source of power - and we finally might be able to do it.
A revolutionary new fuel cell could take in urine and produce electricity and clean water. It might sound silly, but a prototype already exists, and it could provide the unlikeliest possible solution to third world energy and clean water problems.
The Holiday Season is officially on us again, and that can mean only one thing that isn't watching Christmas In Connecticut over and over again: Time to think about gift-giving (and getting). Where better to start than with toys?
Milan Karki, an 18 year-old from a rural village in Nepal, has invented a type of solar panel that replaces expensive silicon with cheap, easily replenished human hair. Melanin, the pigment in human hair acts as a conductor for solar energy, and hair, unlike silicon, can be easily replaced, giving the panels a longer…
