Monthly Archives: May 2009

Since I don’t have much time to blog, I restrain myself to publishing here around 25 articles per month. However, many more great news are worth reading and blogging about. My goal being to provide you with the latest headlines and best researches on sustainable development, climate change and the […]

Worth an article: my May 2009 tweets

This is that time of the month: the one 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 very difficult to select just ten. This month is special as […]

Great astrophotographies – May 2009


I was writing in a comment that solar thermal could and even should provide electricity to the nations of  the Middle East and how it would much better than nuclear. It seems I was quite right. Published by an environmental NGO and various official bodies specialized in solar energy, a […]

A quarter of global electricity can be provided by solar ...


According to a great article from the Huffington Post, 13 countries of this region are negotiating to acquire the technology to build nuclear plants. As an example of this the United Arab Emirates are negotiating to build reactors soon. Why a region rich with two thirds of the global oil […]

Nuclear power plants in the Middle East ?


Further to the discussion I had with Kiashu in the previous post, I thought a recent post from the Oil Drum would be appropriate to continue our discussion on why it seems we have to consume always more and if there are alternatives. A British organization wonders in it’s latest […]

Prosperity without growth


I am currently wondering why are energy conservation and efficiency so unpopular. Indeed, these solutions can cut significantly our greenhouse gases emissions and enable us to save huge amounts of money. Most governments are putting money on renewable energies or stuff like “clean coal“. Instead of the latter, why aren’t […]

Why is energy conservation so unpopular ?


Last week Jean-Louis Borloo, the French energy and environment Minister, launched a plan that will quadruple the amount of electricity provided by solar photovoltaïc in order to reach 300 MW by 2011. This is great news as investing 1.5 billion euros ($2 billion) in solar PV is the right move […]

Solar PV to provide 300 MW to France by 2011


For the fifth part of these series – see the previous articles on heating, electricity, water and transport – I would like to tackle food in general. This is an important issue for both the health and the environment. At a time where weight issues keep on increasing – to […]

Towards sustainability: food


According to a new study by the Massachusetts Institute of Technology (MIT) climate change may reach 7°C by the end of this century. This doubles the previous estimates by the IPCC. As climate models become more and more complex and contain more and more data, the results are increasingly worrying. […]

Temperatures could rise by 7°C by 2100


It seems the arms race is continuing as the People’s Republic of China is willing to get 35 percent of its electricity by renewable energy sources by 2020. This will represent 570 gigawatts of capacity. It is worth noting that the country’s electricity demand is due to double by then […]

China’s electricity will be 35% clean by 2020

The International Energy Agency issued a study – Gadgets and Gigawatts – on the energy consumption of the numerous mobile phones, mp3 players and other electronic devices. By 2030, they are due to consume up to three times more and thus burn up to 700 terawatt-hours of electricity. All this […]

The energy cost of our electronic devices

Yesterday were announced by President Obama the new mileage requirements for US vehicles. This is important as they hadn’t changed for decades. The average mileage will reach 35.5 MPG by 2016 compared to roughly 25 nowadays. This seems to be a lot but it isn’t when one knows that European […]

Mixed feelings about the new US mileage
