Developing nations to cut emissions

Earlier this year I was wondering if cleantech is the new arms race. I noted at the time that America, Europe and China are beginning to compete in such an important economic sector. A US study released last month shows that not only there is an arms race between the […]

The Revelation Space cycle by Alastair Reynolds


Scientific American published in this month’s issue an article on how the world could completely stop relying on fossil fuels (coal, oil, natural gas and nuclear) by 2030 and use only solar, wind and water energies. To make a long story short and after reading the various critics this is […]

According to Reuters Spain will add up to 8.8 GW of renewable energies by 2012. As GreenUnivers [Fr] points out this would increase by 37 percent the current renewable electricity capacity in just three years. This occurs as now wind energy has more installed capacity than nuclear in Spain and […]
