Whatever concerns energy and the ways to produce it goes here
According to the latest report of the Renewable Energy Policy Network for the 21st century (REN21), renewable energies are witnessing an important increase. Indeed global generating capacity of grid-connected solar photovoltaic rose by 52 percent and wind power by 28 percent in 2007, compared to 2006. These renewables are due to have a bright future, …
By reading this month’s issue of the French magazine Science & Vie, I came across a valuable article on a technology called Controlled Auto Ignition, or CAI. This enables oil engines to cut the consumption of regular vehicles by 15 percent, which would bring them to the levels of Diesel engines, without their hindrances. Engineers …

According to the WWF, Shanghaï (and another Chinese city, Boading) joins the Low Carbon City Initiative, a pioneering project from the renown organization. This will enable the cities to decrease their CO2 emissions by working on energy efficiency of buildings as well as the environmental quality. This is great news and I can’t wait for …
I was relating earlier that renewable energies are witnessing a boom worldwide. It seems that nuclear energy might also face the same phenomenon with climate change mitigation. Nuclear has a seriously bad reputation for some ecologists, and this even if it is the second lowest greenhouse gases emitting energy solution. But with the crises of …
Alstom unveiled yesterday its AGV, which is the successor of the TGV (train à grande vitesse, fast speed train) a huge success for the company. The AGV brings several improvements compared to the previous model as it goes faster – 360 kilometers per hour compared to 320 – and consumes less energy. This will make …
I continue my series on the various investments realized in renewables as the Worldwatch Institute released a report giving some data on this topic. According to this NGO, global investments in these various energy sources might reach 66 billion USD in 2007, a sharp increase over 2005 and 2006. The State of the World 2008 …

Investment within Venture Capital in solar photovoltaïc in the United States reached one billion Dollars in 2007. This almost represents a ten-fold increase compared to 2005. Greentech Media proposes for $600 a full report on the importance this energy source has in venture capital (VC) today and will have in 2009. The least I can …
This is the great – and yet very simple – idea developed by a German company, SkySails. The container ship pictured on the left uses one of the oldest inventions: a simple kite. According to SkySails, this enables to decrease by 10 to 35 percent the energy consumption of these boats, which are largely used …
We stay in the arctic region as today’s article is on Norway which expressed its willingness to become totally climate neutral by 2050. Being climate neutral means that one country – or one person – does not emit any greenhouse gases or when it does, offset its emissions. In this article I will have a …
When I was writing in October my article on the clean alternatives to coal, I was planning to add at the bottom a page summing up the pros and cons of each solution. I never did so but still found this document interesting as it sums up quite well the situation at hand. Each and …
