David MacKay, Professor of Physics, University of Cambridge: How can we power a modern lifestyle without fossil fuels? Individual actions saving 10% here and 40% there will not get us off fossil fuels. To eliminate fossil fuel use, we will surely also need to increase the amount of energy we get from non-fossil-fuel sources. Even if we imagine strong efficiency measures and smart technology switches, halving our energy consumption from 125 kWh per day per person to 60 kWh per day, we should not kid ourselves about the scale of the energy challenge which would remain. If Britain and the United States were to "get off" fossil fuels, what would the effect be on Earth's climate? Most of the rest of the world can not afford to "get off" fossil fuels or do not have the right governments, economies, education systems, industrial capacity to do so.

Science and Technology of Nuclear Installations, Xu Cheng, Yanhua Yang, Walter Ambrosini,Dino Araneo: Passive safety systems have been widely applied to advanced water-cooled reactors (WCRs), to enhance the safety of nuclear power plants. For the near term and medium term, the Chinese government decided for advance pressurized water reactors with an extensive usage of passive safety systems.

Dennis Normile, writer for www.sciencemag.org, website for AAAS, American association for the Advancement of Science: Most of the world is turning its back on burning coal to produce electricity, but not Japan. The nation has fired up at least eight new coal power plants in the past 2 years and has plans for an additional 36 over the next decade—the biggest planned coal power expansion in any developed nation (not including China and India).

Jerry Cuttler, D.Sc. in nuclear sciences and engineering, recipient of 2011 International Dose-Response Society Award for Outstanding Career Achievement: Nuclear energy has been very good for our environment. The air, water and land around nuclear plants are clean and healthy. Their design, construction, operation and decommissioning are performed carefully, based on many plant-years of shared knowledge and experience. The amount of energy obtained brim splitting one atom of uranium is enormous - about forty million times the amount of energy obtained from burning one atom of carbon.
