After years of controversial political debate, China has its carbon tax! It has taken the courage of Julia Gillard, the socialist prime minister since 2010, to get there. As of July 1. 2012, 294 companies and municipal councils will be subject to a A$ 23 tax per ton of C02. That is more than twice… » read more

Solar electricity generated from PV panels and mirrors is due to become one of the leading sources of power generation in the 21st century. It is abundantly available and will become cheaper to produce than fossil or nuclear electricity, due to technological advances in thin-film solar cells and conversion rates of solar irradiation. EU researchers… » read more

With sun shine of > 2500 hours per year, North Africa and the Gulf countries are among the best insulated regions of the planet. They are also unequalled in radiation density (2500-3000 kWh/m2/year). Both factors combined make them ideal locations for generating solar electricity. Indeed, the 22 Arab countries, occupying one third of global desert… » read more

Maritime transport accounts for about three per cent of global C02 emissions, as much as air transport. In the absence of an effective international jurisdiction both transport modes have so far escaped an effective curb of their emissions. This situation will change after a decision taken by the International Maritime Organisation (IMO) July 15th 2011.… » read more

In North America and Northern Europe roughly more than one third of CO2 emissions are due to heating, which is correlated to average temperatures from October to April. The latest estimates of the German aggregate energy consumption and CO2 emissions in 2011 confirm this rule of thumb. The total German energy consumption is expected to… » read more
