More efficiency, wind power and nuclear for China

As the world’s first energy consumer and greenhouse gases emitter, the People’s Republic of China is under closed scrutiny from energy analysts. Last week, not one or two but three different news caught my attention on this country. The climate situation there is dreadful as according to CNN massive floods forced 1.6 million people to …

Is it really about nuclear OR renewables ?

I recently wrote a lengthy comment to an article on CleanTechies. Since it took me some time to write, I think I might share it with you : I never understood people stating it’s either nuclear or renewables as to me we need both. Now I don’t understand the “false choice” of nuclear or fossil …

A look at deaths per TWh by energy source

With all the agitation around the Fukushima catastrophe, I thought it would be interesting to put some facts and figures on the dangerosity of  energy sources, including oil, coal, natural gas, some renewable energy sources and nuclear… The global death rate for coal is 161 per TWh (15 in the United States), 36 for oil, …

Generating electricity 40 to 50 % more efficiently

It’s a well known fact, the production of electricity via traditional coal and natural gas burning plants and in a lesser way nuclear reactors is vastly inefficient. But this might change soon thanks to scientific research. To Ecogeek : ” Researchers (…) are developing a new gas turbine to increase the efficiency of conventional electrical …

Can the world be powered by 100% renewables ?

The WWF believes it can be done in four little decades. As they state on their website: ” All of the world’s energy needs could be provided cleanly, renewably and economically by 2050. “ They are right on one point : energy efficiency’s potential is gigantic. Indeed I am reading a book which thesis is …
