The US Department of Energy (DOE) has published on its website a series on infographics and a great animation showing how wind energy is rapidly gaining pace and its capacity is booming. In 2003, there were 185 wind farms online, powering the equivalent of 1.6 million homes ; in 2008, there were 416 wind farms …
Temperatures in northern Europe and parts of the United States are currently colder than average – see these articles from The Independant, Der Spiegel and the Washington Post. Given this, one can reasonably ask : Did the record Arctic melt triggered this cold winter ? To climatologists, it seems likely as previous studies have shown. …
What were you doing when you were 17-year old ? Sara Volz, A Colorado, USA, teen created a biofuel lab in her bedroom. Even better, she developed more efficient algae that produce higher oil content just by selecting them artificially. This is seen as an important boost to algae based biofuels. It was done with …
We have seen it here time and again, burning coal is a huge health issue. This is even more worrying as it is the most polluting fossil fuel and the environmental enemy number One. Now here comes a study from the Health and Environment Alliance – or HEAL – on how this energy source is …

To Bloomberg : ” First Solar, the world’s largest maker of thin-film solar panels, may sell electricity at a lower rate than new coal plants earn. “ ” El Paso Electric Co. agreed to buy power from First Solar’s the 50-megawatt Macho …
I really enjoy infographics as they enable to gather a lot of information in a few moments. The latest I found via Twitter (see left) is on how a cleantech revolution is already taking place in the United States of America. Indeed, since 2007, energy efficiency, renewables like solar and wind (as well as natural …

To Treehugger : “ The National Renewable Energy Laboratory (NREL), and their industry partner Solar Junction, have just set the bar even higher in the race for ultra-high-effiency PV cells by achieving another world record of 44% efficiency. “ But wait, there is more as to another article solar PV panels could soon be 50 …
In September, two important milestones were set for wind energy as installed capacities reached a 100 gigawatts and 50 gigawatts in the European Union and the United States of America, respectively. The 100 GW of wind turbines are producing as much electricity as 62 coal-fired plants or 39 nuclear reactors or 52 natural gas generators …
