This is time for me to present my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD). As always, this month was packed with beautiful images. It was as always difficult to select just ten. My favorite picture for this month is Dark Shuttle Approaching, a […]

Great astrophotographies – February 2010


According to the United Nations’ Billion Tree Campaign, India planted two billion trees since 2007. This brings the amounts of trees planted globally to no less than ten billion. These are fantastic news ! At the beginning of this project, the UNEP wanted to plant a billion trees. This was […]

India planted over two billion trees since 2007


While having a look at the RSS feed of TreeHugger I found something that made me smile : How Australia Could Be Carbon Neutral in 10 Years. Let’s be honest : it really can’t be done. Let’s see why here. The plan outlined by Beyond Zero Emissions states that all the […]

Can Australia become carbon neutral by 2020 ?

At first I wasn’t sure even if I had huge doubts. But now this is a certainty as I came accross three articles on how biofuels production in the United States, Brazil and Europe is a threat to our societies and our environment. In Brazil, biofuels production are a danger to […]

France is promoting via aggressive feed-in tariffs the expansion of solar photovoltaic. I believe this is quite a good thing even if our electricity is 90 percent low carbon. (80 percent nuclear and ten percent hydro) Indeed, we will soon need additional capacity for both heat pumps and electric vehicles. However I […]

Why we should promote solar water heaters more


I know it since my Master’s Thesis : insulating buildings and installing efficient renewable energies heaters is one of the most important ways to cut our fossil fuels consumption and greenhouse gases emissions. Meanwhile,according to a report published by Ernst & Young investing in energy efficiency is in vogue as […]

This was the question I had on my mind as I read that for the first time in 60 years, the US car fleet decreased by four million in 2009. Is this a limited phenomenon or will it continue ? The Earth Policy Insitute believes this trend could last until […]

I wanted to publish for Christmas and New Year’s day a list of books I particularly liked in 2008-09 (I already did a selection in 2007) but couldn’t publish it in time. So, here it is with a few weeks late. From readings on sustainable development and energy issues to science fiction […]

My 2008-09 selection of books



This week was unveiled what is perhaps to date the largest renewable energies project in the world. Indeed, an Indian company – Airvoice Group – plans to build 10 GW of  solar PV capacity and three GW of wind power. All these capacities are due to be built on various […]

We have seen previously that electric cars and vehicles are an interesting alternative to traditional cars with internal combustion engines. But another solution exist : electric bicycles. There are already 65 million e-bikes on Chinese roads and the market size is fastly increasing Such bicycles compete with cars in large […]
