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
On the surface, the StartX Demo Day last night could have looked like any other accelerator pushing its latest class of startups. Nine groups got on stage and fired off presentations about how they were working on something cool, and why they deserved funding.
But it wasn’t the rash of lightweight consumer applications you often see at other demo days. These were Stanford students, particularly technical graduate students, who have been nerding out on solving real problems for years in their labs and dorm rooms, and who are now in the middle of commercializing their hard work. Big-name investors from around Silicon Valley unsurprisingly showed up to check them out. → 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
Thirty spokes meet at a nave;
Because of the hole we may use the wheel.
Clay is moulded into a vessel;
Because of the hollow we may use the cup.
Walls are built around a hearth;
Because of the doors we may use the house.
Thus tools come from what exists,
But use from what does not.
- Tao De Ching
There’s a carousel in a small Cape Cod town that we visited this summer and the kids rode it a few times. The carousel is quite old and quite handsome and it makes a great diversion of an evening. I’m reminded now of trying to take pictures of the kids while they rode the carousel. For a while I’d wave and try to get their attention as they roared past, their laughter dopplering around the edge of the curve, and then, after four or five tries I’d give up and just watch. It’s a wheel, an endless circle, designed to delight and enthuse and distract. → Read More
Electric car drivers deserve to see their positive impact on the environment and their wallets, but the official mobile apps for the Nissan LEAF and Chevy Volt only display remaining battery. GreenCharge is a new iOS app released today that displays your car’s remaining charge, but also its current range, the local energy price, a log of its usage, and your cost and carbon reduction versus driving a gasoline vehicle. Finally, an app that shows how you’re saving both kinds of green. → Read More
Today two musicians sat down with me to have a chat: Andy Ross of OK Go, and Eytan Oren of Eytan and the Embassy. But we weren’t there to talk music.
The dynamic duo actually built an iPhone app called InBloom — a Yelp-style application that offers up sustainable businesses and eco-friendly/dietary food retailers based on location — and sat down with me to tell us how it came to be, and what it’s all about. → Read More

Buildings are blamed for as much as 40% of U.S. energy consumption, and while green construction is on the rise, identifying the best ways to make and older building more efficient can be a tedious manual endeavor. Retroficiency, whose aim is to disrupt the energy efficiency market, eases the process with the help of extensive data sets and predictive analytics.

First, Japan got the world’s first connected home garden device, and now it’s time for Nippon to get the world’s first cloud-based LED lighting system. Developed by Tokyo-based lighting tech startup Net LED Technology Corp., the so-called NetLED system will go on sale in Japan on February 20 (here‘s the company’s English website).
The 40W lights, which have a 40,000-hour lifespan, come with built-in Wi-Fi: users can control each tube over the web after installing the NetLed app on a smartphone, tablet, or computer (the iPhone app is already out, while iPad and Android apps will be released this summer). It’s possible to dim the lights (each tube has 10 different dimming levels) and to turn them on or off. → Read More
The WristQue may look like one of those cloth bracelets worn by old soul Sophomores who spent a semester in Prague and came back with dredlocks and an absinthe fetish, but it’s not. It’s actually a personal climate control system. Let me explain.
The bracelet identifies you to the building and allows it to follow you from room to room. Is the meeting room too cold? Press a button and it starts to warm up. It will also prepare rooms for your arrival, reading your patterns of movement over time. If it sounds creepy, it is. → Read More

Well, it’s that time of year again when families come together to stare moodily at each other over lunch and, in theory at least, we’re supposed to be thinking about others less fortunate than ourselves. To that end, stay you hand before you switch off the office PC and head off for some seasonal shopping. For those CPUs could be put to good work for charity, no less.
The Charity Engine is a non-profit volunteer computing grid. Based on Berkeley University’s BOINC software for grid computing – as used by dozens of famous ‘citizen science’ projects such as SETI@home. Charity Engine’s version of BOINC simply donates what it makes from research projects on its grid and donates the cash to charity, while incentivising users with randomly generated cash prizes. Profit from the commissions from science and industry is shared 50-50 between the charities and prize winners. You can use the invite code for the beta: CRUNCH. → Read More
Google is ending 2011 with an investment that brings its total of renewable energy investments to an impressive $915 million.
The online search and advertising juggernaut this morning announced that it is pumping $94 million in a portfolio of four solar photovoltaic projects being built near Sacramento, California by a solar development company called Recurrent Energy. → Read More
AMEE, backed by O’Reilly and Union Square Ventures among others, set out in 2008 to map, measure and track all the carbon and energy data on Earth. That’s a big job. It’s since won contracts with the likes of the UK Government, CNN, Google, the list goes on. But what it hasn’t cracked is a consumer-facing app which gets the issue of ‘carbon footprints’ into the mind of the ordinary member of the public.
