Energy sprawl is another reason to mix sources

Even if this not new as I wrote about this very issue as early as June 2008, the additional research bring us more data on how renewables – and especially biofuels – need much more land to generate energy than traditional solutions. As you can see with the graph biofuels are by far the least […]

Is waste to energy a good idea ?

There is a lot of buzz going on about waste to energy as many cities are thinking about it. Meanwhile, a CleanTechies’ member started a most interesting series on the matter and one of my follower on Twitter wonders if it should be supported. Personally I think we should reduce, reuse and recycle first –

Why solar air conditioning is a fantastic idea

In these times of heat waves – it was 37°C here in France yesterday  – we all know that solar energy can heat places but it seems the sun could also cool them down thanks to air conditioning. Even if this is not entirely new as I read about such technologies as early as 2005

Floating wind turbine may be a game changer

Offshore wind energy may soon change thanks to a new kind of turbines that literally floats on water. The first 2.3 MW prototype was installed 10 kilometers off the Norwegian coasts on June 8th. Developed jointly by Siemens and StatoilHydro the Hywind windmill can be located where seas depths reach from 120 to 700 meters,

How the US Army is going green

Even if I knew thanks to Thomas Friedman and his book Hot, Flat and Crowded that the US Army is willing to outgreen its opponents, I found more information in an article from the New York Times. The US Army is willing to cut its energy and water to decrease the risks inherent to their

Renewable energies are progressing in Europe

EurObserv’ER published its eighth report on the state of renewable energies in Europe. Both in French and English, it demonstrates the sector is vibrant and is just taking off. As there are too many renewable energy solutions to be handled in a single article, I will only present you here the findings of the report

The UK Low Carbon Transition Plan

The United Kingdom may soon become a climate change model for Europe and other developed nations as it plans to cut by 34 percent its greenhouse gases emissions by 2020 from 1990 levels. Yes, over a third less, this is exactly what the IPCC has been advocating in 2007. These brilliant goals will be reached

Future fuels: forget about oil

I came across interesting articles on what could be the fuels for our cars and planes in the future. This is for the moment just research, but there is no doubt that with peak oil approaching, alternatives are being sought. Even if most if not all cars nowadays run on gas, they could well soon

4,000 MW of wind power in France

I would like to announce that my first article at CleanTechies has been published today. This is both a huge pleasure and a honor to write for such a blog. Here is an extract: According to an article [Fr] from the AFP, the installed wind power capacity in France reached 4,000 MW. In line with

Is Australia doing enough on climate change ?

To Ecogeek, Australia plans to soon install a 1 gigawatt wind farm and this kind of project is due to be followed by more as the country plans to have 20 percent of its electricity coming from renewables by 2020. This seems to be great but the current discussions at the local Senate are being
