Welcome ! As a young French Marketing professional with a Master's in International Management I have been selecting since January 2007 the latest headlines and best researches on sustainable development, climate change, cleantech and the world energy sector.

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 and China. The latter will start banning 100-watt bulbs in October 2012. Last year over a billion of these bulbs were sold in the People’s Republic.
To Grist : ” The ban will save China 48 billion kilowatt hours of power per year. Which, if I’m doing my math right, is the equivalent of almost 100 nuclear reactors or large coal-fired power plants. “
I would like to share with you some personal experience on energy efficiency and sobriety as I got back for a few days to visit my parents. I then noticed my dad has the bad habit of letting some CFLs on.
I told him that this really wasn’t good for their purse and our common planet. I also reminded him that leaving lights on in empty rooms is just pure waste since nobody benefits from them.
His answer was that since they consume very little energy and this is thus absolutely not a big deal. Is he right ? Or am I ? Continue »
CFLs consume up to five time less energy than traditional incandescent and halogen bulbs. This convinced several countries including the European Union and India to increasingly use them.
Now LEDs are slowly reaching the markets. Consuming up to half the energy of CFLs they come in all shapes and colors. Even if they are still very expensive, they can last 35,000 hours and can lead to substantial savings over their lifetime.
So if further to my post on decreasing your electricity use you are switching off your incandescents, why not choosing directly LEDs ? You will find below a list of the main advantages. Continue »
To my regret, I don’t write much on how India is willing to mitigate climate change as I lack information. But today’s the occasion to repair this as I came across two different articles on how the world’s largest democracy is working on this issue.
The country will indeed replace by 2012 400 millions of incandescent light bulbs by CFLs. to TreeHugger, the energy savings and resultant carbon emissions savings will be about 55 million tonnes per year.
This is the occasion for me to present you a website I discovered. India Climate Solutions provides great information on the country’s local initiatives. Continue »
The European Union decided last week to ban all incandescent light bulbs by 2010. This occurs as Australia, Cuba and the Philippines did the same last year.
This is important as the EU and its 27 members accounts for nearly half a billion inhabitants. This law is due to cut by sixty percent the amount of energy used for lightning.
The WWF did more calculations on the projected savings induced by such a move toward sustainability and energy conservation. Continue »
If you had a look recently at the sidebar of this blog, you may have noticed that I added a link on what is RSS just next to the subscription button.
This sends you to a page featuring a great video by the Common Craft Show. This company didn’t stop right there and did the same thing to explain CFL light bulbs in plain English.
In three minutes, those of you who still haven’t switched to these marvels will be convinced to take this first step towards decreasing your bills and CO2 emissions. Continue »
