The first continental-scale reconstruction of temperatures over the past 2000 years has found 20th Century warming was a global event that has produced the hottest global average temperature in 1400 years.
Scientists have announced a collaboration to develop an affordable photovoltaic system capable of concentrating, on average, the power of 2000 suns, with an efficiency that can collect 80 percent of the incoming radiation and convert it to useful energy.
Recycling of tyres is a potentially economically sustainable enterprise providing an ingredient to make a kind of plastic for ever recyclable. But Europeans first need to overcome barriers to adoption.
In the 1990s, scientists described the vision of a 2000 W society, in which each person in the developed world would cut the overall power demand to an average of no more than 2000 W and emit no more than 1 ton of CO2 per year without lowering the living standard. A new survey concludes that a continuous consumption of not more than 2000 W per person seems possible for the major part of the population in this society. However, it will be far more difficult not to exceed 1 ton CO2 per capita.
Representatives from internationally-recognised blue chip organisations including IBM, Cisco, Microsoft and Citrix gathered at Birmingham City University earlier this month to address the problems of energy and material waste within the computing and technology industries.
Goal of the European EURECA project is to develop cogeneration energy technology in the home, anticipating thus energy savings of up to 40%. EURECA focuses on obtaining a cheaper design for fuel cells using new technologies for materials which are cleaner and more efficient than other micro-cogeneration techniques.
The U.S. Department of Energy's (DOE) National Renewable Energy Laboratory and Sandia National Laboratories extend their support for the truSolar Working Group's efforts to develop uniform open source risk scoring standards and rating criteria for solar projects that will facilitate lower transaction and capital costs, and improve project finance liquidity within the commercial and industrial solar segment.
The 10-megawatt offshore plant, to be designed by Lockheed Martin, will be the largest OTEC project developed to date, supplying 100 percent of the power needed for a green resort to be built by Reignwood Group.
Capturing carbon dioxide and storing it in underground rock formations is one proposed solution to mitigate climate change. New knowledge about the chemical reactions between CO2 and the mineralforsterite is helping determine how much confidence can be placed in using igneous rocks with magnesium-rich olivines as a solution for long-term CO2 sequestration.
