All chefs know that 'you have to break some eggs to make an omelet', and that includes engineers at Iowa State University who are using high-frequency sound waves to break down plant materials in order to cook up a better batch of biofuel.
That the United States and Europe have been following different energy policies over the past few decades won't come as a surprise. However, according to one researcher, their divergence - with the US leading 'the shale gas revolution' and Europe investing heavily in modern renewables - is a good thing for the development of both alternative-energy sources.
Researchers identified a number of hotspots both of global climate change impacts and the science that deals with them. New analyses presented at the Impacts World 2013 Conference this week in Potsdam, Germany, revealed that the Amazon region, east Africa and the Mediterranean will experience serious change if greenhouse-gas emissions continue unabated.
Neptune, a pioneering system that performs offshore wind measurements, has begun to operate today at the Petroleum Bridge in Badalona. It consists of an eOLOS buoy to measure velocity profiles and wind direction high above sea level, and NEPTool, a tool that predicts wind speed, sea currents and waves in the short and long term with high spatial and temporal resolution.
Directly removing CO2 from the air has the potential to alter the costs of climate change mitigation. It could allow prolonging greenhouse-gas emissions from sectors like transport that are difficult, thus expensive, to turn away from using fossil fuels. And it may help to constrain the financial burden on future generations.
Lawrence Livermore scientists have discovered and demonstrated a new technique to remove and store atmospheric carbon dioxide while generating carbon-negative hydrogen and producing alkalinity, which can be used to offset ocean acidification.
As part of the Open Government initiative launched by the Obama Administration, Sandia National Laboratories' Technical Reference on Hydrogen Compatibility of Materials has made its debut on the Energy Dataset of OpenEnergyInfo, or OpenEI.
Wind energy capacity is growing rapidly in the cold climates of the world. According to the latest forecasts, between 45 and 50 gigawatts of wind energy will be built in cold climates by 2017, which would mean an increase of as much as 72 per cent since the end of 2012 and investments amounting to approximately EUR 75 billion.
Droughts, floods, crop failures, invading species and diseases - climate change impacts of today and tomorrow come with a raft of buzz words. But the science behind our understanding of the potential consequences of global warming is both much broader and much more fragmented.
Researchers at the University of Alicante have patented a new device that allows more efficiently to cultivate microalgae and can be used as raw material for biofuel or for other valuable substances in the agri-food or pharmaceutical industry.
Pakistan is one of the countries most vulnerable to climate change - risks range from the disastrous 2010 floodings that acted as a wake-up call to retreating glaciers impacting freshwater supply. To confront this challenge, the new Centre for Climate Research and Development (CCRD) took up its work this month - a substantial effort to build up indigenous scientific capacities in a place where substantial climate change impacts are actually happening.
The vision of a society in which each inhabitant of the earth manages to consume only 2000 watts has already been around for 15 years. During this time, there has been a steady increase in environmental awareness in the West. Technology has become more efficient and there appears to be very little standing in the way of a sustainable lifestyle. However, as a study by Empa and the Federal Institute of Technology (ETH) Zurich now shows, Mr and Mrs Swiss are still a long way from achieving this.
