It is no news for you if you subscribed to this website : solar thermal alone could provide up to a quarter of global electricity by 2050. The use of molten salt could enable our civilization to store solar electricity for up to seven hours. Morocco is ideally located to harvest all this energy as […]

One of the many worrying consequences of climate change and global warming is desertification. To an expert it is currently spreading like cancer in the Middle East and in NorthAfrica. Indeed, to data provided by The United Nations Development Programme’s 2009 Arab Human Development Report desertification is threatening 2.8 million square kilometers of land in

According to Enerzine [Fr] and other sources the Desertec Project is getting international support as several companies from Europe, America and Africa are joining the Desertec Industrial Initiative (Dii). The US company First Solar was the first to join in and five more companies from Morocco, Tunisia, France, Spain and Italy followed suit. Desertec is

The UNEP and the World Glacier Monitoring Service published a report showing how glaciers all around the world are melting faster and faster, thus threatening the water supplies of hundred of millions of people. The report then noted that “the average annual melting rate of glaciers doubled after the turn of the millennium.” This scary

Solar energy is to me the panacea for Africa, a continent where 550 million people still lack electricity. With molten salts, concentrating solar could bring light to these populations during important parts of the night. Solar cookers could also help fighting deforestation by removing the need for fuelwood. Now an experiment run in Benin (West Africa) shows

I was previously noting that the Sahara desert is slowly turning green. To a new study hurrying the process and extending it to the Australian outback by planting eucalyptus trees (left) could absorb our global CO2 emissions. Indeed this geoengineering idea would absorb eight billion tons of carbon a year. But we shouldn’t forget that

It is no news if you have been reading this blog as China – alongside with other nations – has been calling the richest nations to cut drastically their GHG emissions by 2020 in order to prevent the worse from occurring. Now the 49 least developed countries are calling the G8 to cut their greenhouse

We have seen it previously, the Amazon Rainforest could become a desert because of deforestation and climate change. As I noted in May a three degrees Celsius increase would destroy it by up to 75 percent. But could global warming help the Sahara region becoming green again ? To National Geographic it could be the

If you are an early reader of this blog you perhaps remember my article on how aerogel, a fantastic material could be made of rice husks. Now comes another great use of this by-product of the most consumed cereal. To Discovery Channel: A new way of processing rice husks for use in concrete could lead

Today is the World Day to Combat Desertification, an initiative raising awareness about this important phenomenon which decreases the amount of water, food and place available to both Nature and Mankind. As the UNEP Executive Director Achim Steiner noted: “Land degradation threatens nearly a billion people in some 100 countries and it is estimated that
