A selection of the latest headlines and best researches on sustainable development, climate change, cleantech and the world energy sector.
  • Welcome to my website !

    A young French Management professional I have been delving into sustainability and energy issues since 2004. Here you will find all the projects I am involved in.

    Started in January 2007, my professional blog offers a selection of the latest headlines and best researches on sustainable development, climate change, cleantech and the world energy sector. Over 1,600 articles.

    All articles are to be found below.

  • For hire !

    After several missions in Marketing, Communications and Quality management - including one in the biogas industry in Colombia - I am seeking new challenges –preferably- in the cleantech and sustainability areas.

    This way I would be able to combine my international management education, my passion for the Internet, my taste for writing as well as my strong languages skills.

A milestone : the modern solar panel is 60 years old

PV60Greentech Media celebrated the sixty years of the birth of the silicon solar cell. At the time, that photovoltaic solar cell was only six percent efficient, while nowadays efficiency is around 15 to 20 percent.

At the time, the New York Times hailed the invention “as the beginning of a new era, leading eventually to the realization of one of mankind’s most cherished dreams — the harnessing of the almost limitless energy of the sun for the uses of civilization.”

By the time this invention is a century old it may well power a tremendous share of our civilization.

Morocco goes forward on cleantech

morocco-flagIt seems Morocco has done a lot in its own energy transition. As RTCC reported the country should be held up as a ‘poster child’ for effective green policymaking according to the World Bank’s top climate official, Rachel Kyte.

This occurs as the country has recently cut its fossil fuels subsidies because the government could afford them anymore. Meanwhile it has incentivise investments in renewable energy, whether domestic or foreign.

This spurred clean energy investments which recently went from $300m (221 million euros) to $1.8 billion (1.3 billion euros). Let’s hope Morocco and other countries in the region will keep on going forward

A short video advocating public transport

take the busIt’s the middle of summer, so instead of telling you to (re) read a Midsummer Night Dream by William Shakespeare, I’d like to share with you a video I discovered while browsing Mother Nature Network.

This 1.30 minute video presenting three videos from Belgian company  De Lijn shows how travelling in groups using public transportation is just the right and intelligent thing to do so. 

While these ads date from 2010 I believe they are just cute enough to make your day – and your commute – much cooler. Read more

Australian PM repeals carbon tax

Australia repeals carbon taxAfter months of hard work the Australian Prime Minister Tony Abbott succeeded in repealing that great carbon cutting tool that is the carbon tax. This is a monumental error that is going in the exact opposite direction where all countries are going.

As RTCC noted : ” The removal of the tax, which priced carbon at $21.50 per tonne, isolates Australia at a time when global moves to address climate change are accelerating.”

” Countries are currently in advanced stages of talks at the UN to agree a deal to curb emissions and limit warming to below 2C above pre industrial levels.”

Fossil fuels are the next subprime danger

fossil fuels subprimeHere is further proof it’s high time to divest to avoid the carbon bubble. The Daily Telegraph published this week a most interesting article on how fossil fuels – oil, coal and natural gas – are the next subprime danger of this cycle as

 The cumulative blitz on energy exploration and production over the past six years has been $5.4 trillion, yet little has come of it. ” There are may reasons for such pessimism on these investment. the author notes among them a few :

Expensive exploration and production with little return ; potential limits to CO2 levels to 450 particles per million ; the increased competitiveness of renewables such as solar and wind… Read more

La Barra, or why we need to clean up our oceans

La Barra squareA few weekends ago I was fortunate enough to go with great friends to La Barra, a beautifully stunning beach in the Parque Nacional Natural Uramba Bahía Málaga on the Pacific coast of Colombia.

The photos I took do not lie, the place is simply magnificient and a great spot to spend a few days far away from civilization. Please go to my Flickr gallery for more pictures. The major tiny backside is that the beach is dirty.

And no I am not talking about the black sand, but about the plastic trash littering the place. Dozens if not hundreds of plastic bottles but also sandals, tampons, bags litter the place. Read more

Caribbean’s coral reefs could vanish by 2030

Healthy corral reefBad news for the oceans : according to the BBC : ” Many of the Caribbean’s coral reefs could vanish in the next 20 years, according to a report published by the International Union for the Conservation of Nature (IUCN). “

” Data from more than 35,000 surveys suggests that habitats have declined by more than 50% since the 1970s. The report’s authors believe that over-fishing and disease is mainly to blame. “

” They say the trend could continue if nothing is done, but with protection the reefs could bounce back. ” Let’s hope something is done about the acidification of our oceans too…

World Bank advocates climate-smart action and cleantech

GDP Report climate smartSo you thought avoiding climate change by investing massively into cleantech would be bad for economic growth and GDP ? Please pray do read on and share. As Euractiv noted :

” Global economic output could rise by as much as an additional $2.6 trillion (€1.9tn) a year, or 2.2%, by 2030 if government policies improve energy efficiency, waste management and public transport.”

To the World Bank, which published the report, ” the same development projects that improve communities, save lives, and increase GDP can also fight climate change.Read more

” Plant, baby, plant ” a reminder

Agroforestry in FranceIn 2012 I wrote a series of articles about planting trees. Given how this simple action solves heaps of problems – such as climate change and air pollution - in both the countryside and in our cities I believe we should make it a priority.

If you believe these are words from a treehugging enthusiast, read on. My first article was agroforestry, ie. trees in the countryside, then we delved on the benefits of urban forestry and to conclude, we had a look at the Billion Tree Campaign.

In these three articles you will learn how trees belong everywhere and how we should start a much more symbiotic relationship with them. Afterward you will only have one idea : planting trees.

Cleantech investments need to soar

A solar installationAccording to a report published in May by the International Energy Agency,  the clean energy investments needed to limit temperatures from warming to 2 degrees Celsius: an additional $44 trillion ( 32 trillion euros ) by 2050.

This means spending an additional $1.2 trillion in cleantech ( like solar, wind, geothermal, bioenergy…. ) per year for the next 36 years is needed in order to limit climate risk. But this represent investments, not costs.

Indeed, these investments would result in over $115 trillion in fuel savings. This represent would a net savings of $71 trillion. (51 trillion euros).  Read more

“We are sharing our resources in a very inequitable way. In a few decades, the relationship between the environment, resources and conflict may seem almost as obvious as the connection we see today between human rights, democracy and peace.” — Wangari Maathai
