Whatever concerns energy and the ways to produce it goes here
I have been committed since January 2007 to bring you each month a selection of the latest headlines and best researches on sustainable development, climate change and the world energy sector. However, I don’t blog as much as I would like to and generally write around 25 posts per month. But many more news are worth […]

Cleantechnica got another interesting article, this time on what the past ten years meant to cleantech and what the next ten years could bring. The occasion is given by Clean Edge’s market research. ” With growth rates like seen in the telephone industry (…) during comparable revolutions, clean energy options like solar and wind have

With all the agitation around the Fukushima catastrophe, I thought it would be interesting to put some facts and figures on the dangerosity of energy sources, including oil, coal, natural gas, some renewable energy sources and nuclear… The global death rate for coal is 161 per TWh (15 in the United States), 36 for oil,

This weekend was the occasion for me to go and visit my family in Lorraine (Eastern France). This enabled me to help out my two uncles and their families cut their water and energy consumption. Indeed, I first helped one family install a rainwater harvesting system that will enable them to water their garden for

We have previously seen here that the European Union could easily achieve a 30 percent reduction of greenhouse gases emissions by 2020 (compared to 1990 levels). This would make a lot of sense both environmentally and economically. Yet the European Commission kept earlier this month on clinging to the 20 percent reduction targets by 2020
EU backs away from 30% emissions target. Again ! Read More »
It’s a well known fact, the production of electricity via traditional coal and natural gas burning plants and in a lesser way nuclear reactors is vastly inefficient. But this might change soon thanks to scientific research. To Ecogeek : ” Researchers (…) are developing a new gas turbine to increase the efficiency of conventional electrical

During my daily hours of ride in the trains to go and come back from the job I read books but also newspapers. This allowed me to read a great article in the New York Times about an unexpected problem with solar power plants in California. ” Just weeks after regulators approved the last of

To CleanTechnica, a new film developed by HyperSolar, a Californian company, could halve the costs of solar panels and boost their efficiency by 300 percent. The film would replace the sheet of glass currently used with solar PV panels. “With HyperSolar as the top layer, manufacturers can use significantly fewer solar cells in the production

According to the Canadian magazine Corporate Knights : ” If the concept of a sustainable city sounds like a paradox, that’s because it is, according to physicist Geoffrey West.” ” Ironically, because of their urban “metabolism,” cities require only 85 per cent of the resources necessary to double in size, and they’re more energy efficient

If you think business is bad in every sectors, think again. To Reuters : ” Brazil, China and India are expected to fuel global investments in clean energy in 2011 that are expected to reach $240 billion. (175 billion euros) The U.N.’s environmental unit (UNEP) said investment in renewable energy hit $180-$200 billion (130-145 billion
