Do you remember Annie Leonard’s great documentaries The Story of Stuff and the Story of Cosmetics ? Well, she did a few other more, including the latest : The Story of Broke. In this eight-minute animated clip, she tackles the huge problem of subsidies of all kinds that are given […]

Annie Leonard’s latest : The Story of Broke

According to the IEA’s annual report, the situation is getting bleaker and bleaker. Confirming that we have five years to start decreasing our global emissions – cf. my previous post on that very matter – it is also providing several other findings. As you can sure imagine, several websites published […]

IEA World Energy Outlook 2011

I was mentioning last week a documentary called The Thorium Dream, produced by Lasting less than half an hour it is an absolute must-watch to grab the potential of this technology. I know we shouldn’t cringe to just one solution. But I now believe that nuclear risk and waste […]

The Thorium Dream


We already saw that solar PV is due to compete in terms of costs with fossil fuels by around 2017 as this energy source is gaining momentum so fast that the Holy Grail – grid parity – might soon be within reach. These are sure great news… But there is […]

Wind power to be competitive by 2016

Here is my latest reflection on Cleantechies : ” The more I delve into energy and climate issues, the more this seems completely evident : we should prefer energy efficiency and sobriety over renewables.“ ” Making efficiency a priority – whereas renewables are the priority nowadays – will without a […]

Prefering efficiency and sobriety over renewables

After three months of crunching numbers for the World Community Grid on solar panels, better water, aids and cancer, I am joining their new project due to combat malaria. Here is why you should join the fight : “ Malaria is one of the three deadliest infectious diseases on earth […]

World Community Grid : GO Fight Against Malaria

The French magazine Science & Vie [Fr] published this month a lengthy series of articles on thorium-based nuclear, and how it could solve the various issues encountered with uranium-based energy generation. Much more safer, without the need to be enriched, Thorium is also four times more abundant than Uranium. Molten […]

Toward risk-free nuclear with Thorium ?

To Enerzine [Fr] the world largest offshore wind farm has gone online in the Irish sea. Walney 2 has a capacity of 367,2 MW, enough to power 320,000 British households. It was also the fastest ever installation. The farm will however quickly lose its title to other projects set to […]

United Kingdom is committed to offshore wind

Incandescent light bulbs are a relic of the past, a vastly inefficient past. Modern alternatives like CFLs and LEDs consume five to ten times less energy. For these reasons, the European Union or Australia have already phased them out. More countries will be doing the same, namingly the United States […]

China & the USA to ban incandescent light bulbs


Remember the Desertec project and how I was convinced ? Their goal is to build solar, wind and other renewable energies facilities to power North Africa, the Middle East and part of Europe. Well, I am not the only one as their first plant will start construction next year. With […]

Desertec first solar plant to start construction

As TreeHugger reports : ” emissions must peak by 2020 and be reduced “well below” 1990 levels by 2050, if we are to have a “likely” (greater than 66%) chance of keeping temperature rise below 2°C by 2100. “ ” If emissions peak at 2030, we may be able to […]

Global emissions need to peak before 2015-2020

You would think that the inventor of the iPod would rest and enjoy the money he made afterwards. Well, he isn’t and this is great news for all of us as Tony Fadell invented a smart thermostat, the Nest Learning Thermostat. Knowing that we adjust thermostats up to 1,500 per […]

Smart thermostat programs itself to save energy
