The scientific journal Nature featured a loud addition to the climate debate last week by a team of UC-Boulder professors led by Roger Pielke, Jr, a noted climate and policy blogger at Prometheus. The paper (pdf) argues that the Nobel Prize winning IPCC assumed too much […] Read more »
Among clean tech solutions, we often hear about wind, solar, geothermal, and then “energy efficiency.” This one large category rarely gets the specific treatment–other than a mention of compact fluorescent lightbulbs–that the other segments of the market do. But one company we found, Sustainable Spaces, has […] Read more »
A few weeks ago, many greens jeered when Richard Branson put a little J05 biojetfuel in the tank of one of his airliners. It was not enough, others said, and at worst, it was a distracting stunt. In the greentech world, we see the ‘problem’ as […] Read more »

High oil prices have driven investments into biofuels and alternatives to petroleum-based product options. Even though some of the efforts appear misguided from an environmental perspective, the influx of cash has allowed a variety of new ideas to receive funding. But dirty solutions to the price […] Read more »
Investments in Indian cleantech companies increased a dramatic 58 percent in 2007, growing to $210 million from $133 million in 2006. The numbers are part of the Cleantech Group’s new report, “Cleantech India Venture Capital and Private Equity Investment,” and were announced today at the Cleantech […] Read more »
We all know that corn-based ethanol isn’t the route of choice to a sustainable future, but what if corn wasn’t really corn at all? Researchers at Iowa State have pieced together the genome of maize and will announce it Thursday at the oh-so thrilling-sounding Annual Maize […] Read more »
Richard Branson’s Virgin Atlantic conducted the first flight of a commercial aircraft with some jet biofuel in the 747′s tank. You can basically call it ‘J05′ as the biofuel represented a mere 5 percent of the total fuel mix — three of the plane’s four tanks […] Read more »
When the journal Science publishes two studies questioning the greenhouse gas reduction benefits of biofuels, it’s bound to garner attention even if the cleantech community has long known that first-generation biofuels are not the answer to global climate change. And, combined with a paper deriding the […] Read more »
With advocates of “cleanish coal” bummed out about the government’s decision to pull the plug on the FutureGen coal with carbon capture and sequestration facility, we thought you might need some more positive news about sequestering gases. It comes courtesy of University of Calgary chemistry professor […] Read more »
A Polish coal plant, which will cofire biomass (burn biomass at the same time as coal) to help reduce its emissions by 25 percent compared with the country’s current coal plants, is due to come online in 2009. A major Polish power group, Poludniowy Koncern Energetyczny, […] Read more »

With its purportedly aggressive plans for the Volt and the Coskata biofuels deal, these days we find ourselves in the somewhat awkward position of rooting for GM. The company has yet to return to profitability, but sees new signs of hope on the horizon amidst its […] Read more »
Here’s an investing thesis that’s conceptually easy to grasp: India needs to spend $500 billion by 2012 building power plants and infrastructure to deliver power to its citizens, so invest in Indian power plant builders. On the strength and clarity of this seemingly sure winner, investors […] Read more »
Portable fuel cells capture the imagination of just about all laptop warriors with their promise of unending off-grid power on the go. But they remain just a dream. As part of the new eco-focus at CES, Horizon Fuel Cell Technologies, headquartered in Singapore, is showing off […] Read more »

The news broke earlier this week that Khosla Ventures had placed another chip on the biofuels roulette table, this time betting on the Cambridge startup Ethos, which aims to become a player in Latin American ethanol production. The investment follows more than 10 other bets that […] Read more »
We recently wrote about the rise of solar services companies, those that will come to your house and install an entire solar system, kind of like DirecTV dish installers (e.g. Ironwood Communications). The rise of these companies is a major signal that renewable energy, at the […] Read more »
If granted patents are an indication of innovation in a sector, clean technology breakthroughs are up significantly over the past five years, but down slightly from 2006. In 2007 a little less than 900 patent applications were granted. That’s compared to 2002, when less than 750 […] Read more »
First BP quietly demoted its renewables division and decided to invest in dirty tar sands oil production. Now Shell has sold off the majority of its solar business. It’s almost like Big Oil, which has invested hundreds of billions of dollars in its infrastructure, doesn’t really […] Read more »
There’s two ways to build an organism these days: from the top down or from the bottom up. Classic genetic engineering focuses on changing one or two genes out of the whole genome. The emerging field of synthetic biology takes the opposite tack in that it […] Read more »
Solar stocks have been volatile, but mostly hot throughout 2007. Jefferies Company put out a notably positive note on a number of solar plays last week, including Suntech and Sunpower.

Lo and behold, Good Energy, a shareholder in Trina Solar, has upped its stake in Chinese PV manufacturer SolarFun (SOLF) from 6% to 35%. Could a merger between Trina […] Read more »
Kalama, Wash. is just a speck off the I-5 between Portland and Seattle, but it’s turning into an early battleground over the viability of carbon capture and sequestration. The Washington Energy Facility Site Evaluation Council this week rejected a proposal to build a $1.5 billion coal […] Read more »
Climate change is going to cost a lot of money. At this point, the question is whether those costs will be for mitigation and investment — or clean-up. The UN Development Program released a report this week that put a number on the cost of mitigating […] Read more »
Remember those old sci-fi movies in which future humans would “terraform” Mars (or some more distant planet) to make it more like the relative paradise of our blue-green Earth? Well, it turns out we’re already honing those terraforming skills, and they’re aimed at making our own […] Read more »
Trina Solar today reported a third-quarter profit rise of 87 percent, but the results fell short of analysts expectations, sending its shares to close down nearly 24 percent. Yet even with the decline, Trina’s stock is up 84 percent since its December 2006 IPO. Trina’s shortfall […] Read more »
It seems like poplar trees can do everything these days. In addition to naturally absorbing carbon dioxide for us, they’ve been genetically modified to remediate soil. Now, the New York Times reports that North Carolina State researchers have created a poplar variety with 50 percent less […] Read more »
The Intergovernmental Panel on Climate Change, the Nobel Prize-winning group of scientists that mainstreamed the idea that carbon emissions were the main cause of climate change, on Saturday released a summary of their findings aimed at policymakers (pdf).
