According to TreeHugger, graphene could offer 60% solar cell efficiency if it were to replace silicon in PV panels. As they note : ” Researchers from the Institute of Photonic Sciences in Spain have just published results from their experiments.” ” While their results so far will probably be more useful to make better image […]

Do you know Kickstarter, the world’s largest funding platform more used to fund video games and other similar projects ? Well, one of its recent successes is the Nanolight, perhaps the world’s most efficient light bulb. Only consuming 12 W to offer the light of the traditional 100 W incandescent bulb, the Nanolight was developed

The Regional Greenhouse Gas Initiative was started a few years ago to cut greenhouse gases emissions in nine Northeastern States in the USA. As I noted previously, it has been so far a great success. But it is ready for more. As the New York Times reports : ” The regional group proposed a 45

Earlier this week, the newly reelected US President Barack Obama addressed the nation in the annual State of the Union address. It was the occasion for President Obama to keep his hard stance on climate on energy. His previous speech during his second inaugural address had been a new hope for climate change. I stated
Another great Obama speech on climate Read More »
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

Yesterday I published an lengthy article on how business leaders and elected representatives of the so-called ” developped countries ” are awakening slowly to the threat of climate change. While these are great news, we are still waiting for concrete actions that could actually have a chance to avoid catastrophes such as flooded cities, extreme

Oops, I did it again ! I totally forgot to publish the selection of my best tweets of November. Luckily for you all, I just did, so please don’t hesitate to go and read this article. In today’s post you will find the informations on climate or environmental issues, sustainability and the world energy sector
Worth an article – my December 2012 tweets Read More »
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

A great innovation I have seen on French cars recently is called Stop and start. Peugeot Citroen (PSA) started selling this anti-idling technology as early as 2006. The gains in urban driving are no less than ten percent… Indeed, thanks to start-stop systems, the internal combustion engine is automatically shut down while you are stuck
Start-stop systems are simple, yet brilliant Read More »
My current apartment in Valenciennes – Northern France – is located in a recent building (2000). And far from me the idea of bragging, but until temperatures dropped below zero (Celcius) I almost didn’t not use my electric heaters. My flat has double glazing windows and quite well insulated thick walls. The thermometer located in
