Whatever concerns my life goes here.
It is said in France that we have to cut by a factor four our emissions of greenhouse gases by 2050 compared to 1990, and in a global scale by a factor two. It might seem impossible. But the more I am thinking about it, the more I believe it actually can be done if …

I have been willing for now some time to go back to London, and this for two reasons. First, to go back in a city I truly loved to visit as a teen (my last visit there was in 1998). The second, to have a look at the possibilities of me working there. My education …
Je n’ai rien publié ici durant la dernière semaine de février car je travaillais sur un dossier sur le solaire photovoltaïque suite à une commande qui m’avait été faite. Comme c’est mon travail personnel je vous en propose l’intégralité. Il porte sur deux aspects : les principaux marchés et un comparatif entre l’éolien et le …
Ceci est mon premier post depuis mon EEE PC acheté la semaine dernière. Minuscule, il ne pèse que 900 grammes et est un ordinateur à part entière. Totalement silencieux, il permet de se connecter sur Internet via le Wifi embarqué, d’écouter de la musique et regarder des vidéo. Pour 300 €, je dispose donc d’une …
As I noted in the previous post, I have been lately quite a lot in trains to go to Paris and Besançon for my job research and leisure. Using the train enabled me to avoid the emissions of nearly 240 kilograms of carbon dioxide as if I had been going by car. I have to …

Last weeks were particularly poor in new articles and this can be partly explained by the fact that I have been traveling around for my job research and other reasons. Indeed I went twice to Paris for job interviews and twice to Besançon where I spent a day each time. Having no means (yet!) to …

Albeit the fact I consider myself as an ecologist and took various actions to decrease my greenhouse gases emissions, I never really did any calculations of my impact. But the New year’s day brought me an opportunity to have a look at my CO2 emissions as I went to Nancy by train and I avoided …
This week-end I had the opportunity to look at the sky at night. I discovered with great joy that the Orion Constellation (left) is right in front of my window at midnight. By using Stellarium, a great freeware displaying exactly the sky one has in front of him/her, I discovered Sirius, Betelgeuse, the Pleiades star …

For this month’s cultural break – with some late, again – I would like to talk to you about the latest Pixar animation movie, Ratatouille. I had the opportunity and pleasure to see it two weeks ago with Qat and his family. The least I can say is that we really enjoyed it. From the …
I have been reading and enjoying for some months the Business of green blog from the IHT. The RSS feeds of this blog are displayed on my sidebar. Today I was reading their latest article “Do low energy light bulbs work?” and I felt like giving my humble opinion on that matter and posted a …
