I wrote a post for CleanTechnica on December 6, 2011 about something I’d never before heard about, integral fast reactors — you guessed right, nuclear reactors. Titled, “Our Nuclear Trash Heap Needs IFRs,” I wrote about a 2008 book by environmentalist, Tom Blees, “Prescription for the Planet.”
In honor of Earth Day, EcoScraps is pleased to announce that in the past 12 months it has diverted over 30 million pounds of food waste from landfills, an environmental milestone equivalent to removing 3.5 million cars from America’s roads for a day.
According to Michael T. Coe, Senior Scientist at The Woods Hole Research Center (WHRC) and one of the issue’s co-editors, “One important finding presented in these papers is that landowners respond quickly to external and internal forces, particularly signals from government and market forces to be better land stewards.”
Masdar, Abu Dhabi’s renewable energy company, today launched an US$31.99 million utility-scale, 15-megawatt solar photovoltaic (PV) power plant in the Islamic Republic of Mauritania. The Sheikh Zayed Solar Power Plant is located in the capital city of Nouakchott and is the largest solar PV plant in Africa. The new facility accounts for 10 percent of Mauritania’s energy capacity and will displace approximately 21,225 tons of carbon dioxide annually.
“Carbon dioxide removal from the atmosphere allows to separate emissions control from the time and location of the actual emissions. This flexibility can be important for climate protection,” says lead-author Elmar Kriegler. “You don’t have to prevent emissions in every factory or truck, but could for instance plant grasses that suck CO2 out of the air to grow – and later get processed in bioenergy plants where the CO2 gets stored underground.”
Families can be key players in a revolution needed to feed the world, and could save money by helping to cut food losses now occurring from field to fork to trash bin, an expert said here today. He described that often-invisible waste in food — 4 out of every 10 pounds produced in the United States alone — and the challenges of feeding a global population of 9 billion in a keynote talk at the 245th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.
A new study shows clean-air regulations have dramatically reduced acid rain in the United States, Europe, Japan and South Korea over the past 30 years, but the opposite is true in fast-growing East Asian megacities, possibly due to lax antipollution rules or lack of enforcement.
Rice University team seeks to optimize CO2 removal from power plant emissions In some of the first results from a federally funded initiative to find new ways of capturing carbon dioxide (CO2) from coal-fired power plants, Rice University scientists have found that CO2 can be removed more economically using “waste” heat — low-grade steam that cannot be used to produce electricity. The find is significant because capturing CO2 with conventional technology is an energy-intensive process that can consume as much…
In an article published March 15 in the journal Science, Edward Parson of UCLA and David Keith of Harvard University outline how the current deadlock on governance of geoengineering research poses real threats to the sound management of climate risk. Their article advances concrete and actionable proposals for allowing further research — but not deployment — and for creating scientific and legal guidance, as well as addressing public concerns.
BU-led international team shows significant reduction in temperature and vegetation seasonality over northern latitudes An international team of 21 authors from 17 institutions in seven countries has just published a study in the journal Natural Climate Change showing that, as the cover of snow and ice in the northern latitudes has diminished in recent years, the temperature over the northern land mass has increased at different rates during the four seasons, causing a reduction in temperature and vegetation seasonality in this area.…
The following websites addressing global climate change come from the National Aeronautics and Space Administration. I was happy to discover such a wealth of information. This compendium that should be shared far and wide, in schools, churches, neighborhood associations, and more.
Chemists at the University of South Florida and King Abdullah University of Science and Technology have discovered a more efficient, less expensive and reusable material for carbon dioxide (CO2) capture and separation. The breakthrough could have implications for a new generation of clean-air technologies and offers new tools for confronting the world’s challenges in controlling carbon.
“Ten percent of the Lower 48 has been leased by oil companies. That’s more acreage than we plant in corn and wheat. Oil and gas extraction is now the dominant land use on the continent. “In short, shale plays are a peculiar sort of blessing. For sure, they’ve given us a staggering amount of new energy. Simultaneously, they’ve hijacked our energy future, chained us to a drilling rig, and thrown away the key.” Source: The Christian Science Monitor Randy…
The GBPN launched today its participative global Knowledge Platform advancing best-practice policies in building energy performance. www.gbpn.org, the new GBPN web-based tool, will stimulate collective research and analysis from experts worldwide to promote better decision-making and help the building sector effectively reduce its impact on climate change.
Kennedy and Sugar make the claim in ‘A low carbon infrastructure plan for Toronto, Canada,’ published in the latest issue of The Canadian Journal of Civil Engineering. The paper aims to show how cities can make a positive difference using realistic, achievable steps. Their research shows that it is technically possible for cities to reduce their greenhouse gas emissions by 70 per cent or more in the long-term.
