Quelles énergies dans le monde pour 2050 ?

by  Jean-Louis Schilansky, Président du Centre Hydrocarbures Non Conventionnels, 3 Avril 2017


Le début du XXIe siècle connaît une période inédite d’abondance et de diversité énergétique, marquée par d’importantes avancées technologiques dans la production d’énergie. Les développements les plus notables concernent l’essor des énergies renouvelables et des ressources d’hydrocarbures non conventionnels, en particulier de pétrole et de gaz de schiste en Amérique du Nord

When will Earth lose its oceans?

by J.  Lecomte et al., CNRS, December 16, 2013

The natural increase in solar luminosity — a very slow process unrelated to current climate warming — will cause the Earth’s temperatures to rise over the next few hundred million years. This will result in the complete evaporation of the oceans. The first three-dimensional climate model able to simulate the phenomenon predicts that liquid water will disappear on Earth in approximately one billion years, extending previous estimates by several hundred million years.

China and Pakistan Join Forces For World’s Biggest Brown Coal Programme

by Dr. Benny Peiser, April 3, 2017


Chinese engineer and inventor Feng Weizhong has an easy ­answer to how China plans to keep slashing coal use and power-­station emissions while relying on coal to provide at least 55 per cent of its massive energy demand for decades to come. The effervescent Professor Feng, who is also general manager of a large Shanghai power plant, explained to The Australian how the country can contrive to do both at the same time. “Simple! It’s clean coal!”
