21 countries from Austria to the United States have cut their greenhouse gases emissions while growing their economies in the past 15 years. This proves that decoupling economic growth and greenhouse gases emissions is feasible.
Here is another article published at Cleantechies on how Switzerland is showing some leadership by targetting 50 percent greenhouse gases emissions cuts by 2030. This is a bold move that deserves to inspire other countries.
The future will be solar powered. We have seen it time and again. But for those fearing a world full of black or blue solar panels, have no fear. If I had reported about colored solar panels in 2010, here is something new…
To Climate Progress, Swiss researchers working with IBM ” have built a new solar dish, called the High Concentration PhotoVoltaic Thermal system (HCPVT) that tackles the waste heat problem by using it to generate fresh water.” Yep, a solar installation that generates fresh water, thus solving two common problems faced in developing nations around the world.… Continue reading Solar electricity, A/C and water. All-in-one.
Last week in Davos, Switzerland, took place the annual World Economic Forum. As the financial crisis of 2008 is drawing to an end, climate change is emerging as a key crisis that has to be addressed as soon as possible. To Reuters : ” Christine Lagarde, managing director of the International Monetary Fund, summed it… Continue reading Hope for climate in Davos’ World Economic Forum
Further to the catastrophe in Fukushima, Japan, the Christian Science Monitor wrote an interesting article on the ten countries relying for more than 30 percent on nuclear for their electricity. As they put it : ” As dependent as Japan is on nuclear power, 12 nations are even more reliant it, according to the World… Continue reading Countries with more than 30 percent of nuclear
To GreenTech Media : ” SunPower just announced their newest solar panels with total area efficiencies of more than 20 percent. The 96-cell solar panels use SunPower’s 22.4 percent efficient cells .” To Ecogeek : ” Researchers at Empa (the Swiss national research laboratory) have achieved a new record in thin-film solar cell efficiency. (…)… Continue reading Solar PV gets even more efficient and cheaper
I think this is a record of some sort as I am only publishing today my selection of astrophotographies for February… Anyway, here is my selection of the best pictures of the NASA’s Astronomy Picture of the Day (APOD). This month is a bit special as my favorite is a video : ” How big… Continue reading Great astrophotographies – February 2011
The solar powered plane Solar Impulse flew for over 26 hours without interruption and landed on July 8th. This plane has a wingspan of 63 meters – the same as a Boeing 777 – weights 1,600 kg and goes as fast as a scooter, 70 km-h. The plane gathered enough energy from the sun during… Continue reading Solar Impulse flies for 26 hours non-stop
The New Ecologist proposes a series of interesting figures on recycling. Here are some of them : The recycling industry is worth $160 billion and employs globally 15 million people. Recycling aluminium needs only five percent of the energy needed to mine and refine the same quantity of new aluminium. The top 5 recycling countries… Continue reading Recycling by the numbers
To the latest report of the European Environment Agency, climate change “poses a grave threat” to the snows of the Alps, and thus will decrease the amounts of water received by many rivers like the Danube, Rhine, Po and Rhone. At the center of Europe the Alps – like the Himalayas are for Asia –… Continue reading The Alps are endangered by climate change
After Russia, the United Kingdom and Italy, Switzerland is the fourth European country in just a few months to seriously think about building new nuclear reactors. This occurs as current Swiss nuclear reactors are due to close around 2020 and the energy demand is increasing in an important way and this is due to continue.… Continue reading Switzerland is considering building a new nuclear plant
