Scientists at the University of Cambridge in the UK have found a way to improve the efficiency of photovoltaic cells by as much as 25% through harnessing more of the sun’s spectrum than most traditional silicon-based solar cells can. → Read More
The future of easy home energy monitoring may be a little bit closer, thanks to a government initiative designed to allow consumers direct access to their energy consumption data.
The White House’s new Green Button gives utilities a way to simplify and standardize sharing usage statistics with their customers via a one-click download. Two California providers, Pacific Gas & Electric and San Diego Gas & Electric, already launched the feature, adding what is literally a green button to their websites. Utility companies in other regions are expected to implement it within the next year. Customers can click the button to download their personal usage information in one place. → Read More
Quick, what’s the second most traded commodity in the world, after oil? Sorry, no: it’s not coffee. In fact, while hard data is scant, it may well be — of all things — carbon. No, really. According to the World Bank (PDF) , the global carbon market was worth a whopping 1.42 Facebooks US$142 billion in 2010.
Mind you, it’s not like container ships weighed down to the gills with graphite are crossing and recrossing the Pacific every week. What we’re actually talking about here is the trade in carbon offsets, ie, the absence of carbon. Very Zen, no? Anyway, techies should be comfortable with this notion; I seem to recall spending less time studying electrons than I did “holes,” ie their absence, while acquiring my EE degree.
Anyway, where there’s a $twelve-figures market, there are startups fighting for a share. In particular, there’s a bit of a war on to see who will be the primary aggregator of carbon-market data. On one side, dominating the market, I give you the Goliaths Point Carbon, a tentacle of the Thomson Reuters kraken, providing “independent news, analysis and consulting services for European and global power, gas and carbon markets,” and Bloomberg New Energy Finance, doing much the same. On the other, I give you plucky little David eCO2Market, a Paris-based startup with an algorithmic sling. → Read More
Flying a kite to produce power may conjure up images of Ben Franklin, who sought to prove lightning was electric. Makani Power releases turbine blades into the air, seeking to harness wind energy at higher altitudes. → Read More
Spiderman might soon lose his dominance in harnessing spider silk superpowers. Scientists from the University of Wyoming, the University of Notre Dame and Zhejiang University in China have genetically modified silkworms to spin stronger silk using spider genes.The new material could be used for everything from bulletproof vests to replacing tough plastics. → Read More
In an unusual hybrid, British industrial designer Phil Pauley created Marine Solar Cells that harness energy from both the sun and water.
The web of energy generators capture energy off-shore, using a combination of floating photovoltaics and natural buoyancy displacement. Thanks to the reflective nature of water, the solar component’s efficiency is up to 20% greater than it would be land-locked. → Read More
Many in motoring are looking forward to an all-electric future, but as long as we’re burning fuel we’ll need to keep incentivizing low emissions. In California, a limited number of low-emissions vehicles are given stickers that let them travel in the HOV lanes, which residents know is a hell of a perk. Now Volt owners can get in on that action.
Chevrolet is making a low-emissions package standard in Californa for the 2012 model (which we’ll be testing soon), making owners eligible to apply for one of the stickers. → Read More
Even though plants need only a few things to grow – water, air, light and minerals – maintaining the right proportions can make gardening feel like a high-maintenance hobby. Estonian company Click & Grow creates soilless, electronic flowerpots that do the work for you, providing the correct water and nutrient balance for indoor plants.
For some, this may seem like a superfluous product since many varieties of houseplants don’t require an excessive amount of care. But for those with a history of killing their flowery friends, or those whose travel schedules don’t permit regular waterings, Click & Grow could be a helpful solution. → Read More
Oregon Manifest, a nonprofit located in Portland, has been running a competition over the last few months in which students and pro teams work to create a next-generation city bike. This isn’t about speed (like the McLaren Venge) or concept design (like the Vienna Bike), but rather about creating a bike that provides the maximum amount of utility for someone looking to ditch their automobile.
These innovation-from-competition events are really blowing up; there have been lots lately aimed at creating everything from mega-efficient cars to electrically-powered aircraft. This one had 34 entrants who mostly had some variation of a cargo bike with electric assist, but they all varied in execution. I have to agree with the people’s choice, though, a collaboration between IDEO and Rock Lobster (pictured). → Read More
A little more than a year ago, we posted about the possibilities of electric aircraft. At the time, we also mentioned an upcoming competition that would test the mettle of these flying batteries: the CAFE Green Flight Challenge. It’s a NASA event (and purse), sponsored by Google, which like the X-Prize aims to fund innovation through competition. Entrants would have to fly 200 miles in under two hours, while using less than a gallon of fuel (or equivalent energy) per passenger.
Tough terms, but 10 teams put their designs in flight in a quiet, efficient battle for the $1.35 million prize. → Read More
The spectacular failure of solar manufacturer Solyndra is being held up by some as a shining example of the Obama administration’s failure to properly manage government subsidies after its collapse left taxpayers with $535 million in federally guaranteed loans. But Solyndra’s failure on its own is not remarkable. There are always risks involved when you’re introducing innovation into a commoditized market. The bigger, and still unanswered, question is why did it take this much capital before it failed, given the warning signs? → Read More
Back in March, we heard about a breakthrough from MIT: an “artificial leaf” that produces pure oxygen and hydrogen gas, powered entirely by sunlight. The technology was described in yesterday’s edition of Science, and the team has released a video showing one of the devices in action. → Read More
One future source of green energy may be as close as the nearest dumpster thanks to companies vying to make fuel from trash. Enerkem, based in Montreal, and Fiberight, in Maryland, hope to turn municipal waste into energy in new biorefineries.
Enerkem has been around since 2000 and owns several facilities in Canada. Its pilot plant, in Sherbrooke, Quebec, turns used electricity poles into methanol, acetates, ethanol and syngas. Future plants will use municipal waste as a feedstock. → Read More
2011 Boulder TechStars graduate Simple Energy is teaming up with San Diego Gas and Electric (SDG&E) to help the utility engage its customers in energy conservation efforts.
To accomplish this, Simple Energy is running an energy saver contest that offers a social gaming experience with real-world rewards. → Read More
When it comes to renewable energy solutions, sometimes nature has the best ideas. That was 13-year-old Aidan Dwyer’s conclusion after a wintry hike in New York’s Catskill Mountains, a trip that inspired him to build a unique and effective solar array design.
Dwyer observed patterns in the trees and, after further research and contemplation, realized the branches matched up with the Fibonacci sequence, a mathematical pattern found throughout nature, such as in falcon flight paths, nautilus shells and ratios within the human body. → Read More
Aviation enthusiasts interested in greener flying might put an Elektra One plane on their wish lists. PC-Aero‘s electric aircraft can fly for up to three hours on one charge with a 100mph cruising speed. The charging happens inside a solar-powered hangar included in the plane’s anticipated purchase price of $145,000. → Read More
Those who resist purchasing an electric car because charging stations are less ubiquitous than gas stations or figuring out how to charge your car at home seems complicated have one less excuse to go green. A new system from British startup HaloIPT allows cars to be charge wirelessly using induction.
The wirelessly transmitted power goes to the car’s battery for an ongoing charge, similar to the concept of recharging an electric toothbrush but with a lot more energy. Each car is outfitted with a pad underneath the car that is ready to receive power. → Read More
For many people, building with Legos brings back fond memories. For Mike Schropp, the memories are still being built. Schropp loves Legos, often incorporating them into technology. For his latest project, Schropp built a 12-core PC tucked into a custom made case he designed using some 2,000 black Lego bricks. The finished product is not only awesome looking, but also energy efficient.

Group buying is moving into the commercial clean energy space thanks to Solar@Work, a program designed by San Francisco’s Department of the Environment to make solar panels more affordable for business owners. Businesses have three options for acquiring solar panels through the program: Purchasing, leasing, and securing a loan. A federal grant covering 30% of installation costs is also on offer.
Solar@Work hopes to sign on at least 20 building owners in the San Francisco area by the end of the year, which could translate to as much as 2 megawatts of solar power.
While the program is innovative in simplifying solar for commercial buildings, it is not the first to harness group buying power for solar. 1Bog has a similar model for home-based solar installations, and SolarMosaic provides a crowdfunding platform for bringing solar to community buildings such as schools and churches. → Read More
There has been a fair bit of concern in recent years about the ability of our power plants to supply adequate electricity during periods of peak demand. Hydrostor, a Toronto-based company, is taking a different approach and offering a solution that allows plants to store their power using compressed air in underwater storage tanks.
Hydrostor converts excess electricity into compressed and stores it under a body of water, when the electricity is needed the weight of the water forces the air back to the surface where it’s converted back into electricity. This technology allows for the removal of renewable energy intermittency, decongestion of transmission and distribution lines, and better efficiencies of existing generation. → Read More
