Whatever concerns energy and the ways to produce it goes here
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.

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 …
If you think gasoline is too expensive, you haven’t seen anything yet… To the Wall Street Journal : ” Nomura Securities says that if Algeria joins Libya in the land of chaos, oil prices could shoot to $220 a barrel. That’s in a worst-case scenario.” “To back up that headline grabber, Nomura compares the current …
We all know it : energy – and resource – efficiency is the panacea to all our energy and environmental woes. As I finished reading another excellent book on the very matter, I am sharing with you today the main findings. Factor Five is the sequel of the 1997-book Factor Four. It demonstrates how our …
We might be led to thinking that with global warming, we won’t be freezing anymore during winters. Counter-intuitively, this won’t be the case as I wrote in December as global warming may mean colder winters… So we should better learn how to keep warm while still not touching the thermostat or insulating our houses and …
It made the headlights last week on practically all environmental websites. The hidden costs – the negative externalities if you prefer – of coal are of 500 billion Dollars per year for the United States alone. Yes, you read it right : burning coal costs the country half a trillion dollar on health costs, premature …
