17 January 2016, Climate News Network, Grasses’ growing role for American cars. Second-generation biofuel made from natural grass species challenges ethanol derived from maize crops as the US seeks to reduce its fossil fuel use. In tomorrow’s world, it won’t be just the corn on the great American plains that is as high as an elephant’s eye. It will be the elephant grass as well. To deliver on US promises to reduce fossil fuel use, American motorists in future will drive on miscanthus − as elephant grass is also known – and prairie switchgrass. Researchers led by Evan DeLucia, professor of biology at the University of Illinois, report in a new journal, Nature Energy, that to exploit biofuels – which recycle carbon already in the atmosphere, and are therefore technically “carbon-neutral” – Americans will have to think again about how they manage the change away from fossil fuels. Right now, the US Environmental Protection Agency’s Renewable Fuel Standards foresee that by 2022 American motorists will start up their cars with 15 billion gallons (57 billion litres) of ethanol from corn. But this could be augmented by 16 billion gallons (60 billion litres) of biofuel derived from perennial grasses. Energy source The switch to the prairie’s native switchgrass (Panicum virgatum) andEurasian elephant grass (Miscanthus giganteus) will be necessary because there are problems with corn as a source of energy. One is that, in an increasingly hungry world, it reduces the overall levels of food available. The second is that corn requires annual planting, fertilising and harvesting. Perennial grasses simply grow, and can be mown once a year. So by turning over surplus land to swift-growing grasses, and at the same time reducing the levels of carbon dioxide released from cultivation, the US could meet its target of a 7% reduction in its annual transportation emissions by 2022. If farmers went on gradually to switch from corn to the grasses, the reduction could get as high as 12%. Read More here

14 January 2016, Climate News Network. Science opens routes to energy recycling. From turning carbon dioxide into a fuel to enabling cars to run on water, scientific researchers worldwide are unlocking the potential of new energy sources. Molecular biology has been used by scientists in the US to make a catalyst that can split water into hydrogen and oxygen. It means that a truly renewable biotechnological material could be used to help cars run on water. In China, chemists have announced a nanofabric – a catalyst put together atoms at a time – that could begin the process of turning the greenhouse gas carbon dioxide back into fuel. And with what seems like perfect timing, a new technological venture in Switzerland hopes to be the first commercial plant to harvest carbon dioxide from the air. The first two propositions are still in the laboratory stage, and the third has yet to prove its viability. But the laboratory advances keep alive the hopes of the ultimate in energy recycling. In the first process, water provides the energy for a chemical reaction that propels a vehicle, and then ends up again as water from the exhaust pipe of a car. And in the second, a gas released as emissions from fossil fuel could get turned back into fuel. Read more here
14 January 2016, Energy Post, The oil pricequake will doom the global political order. Given the centrality of oil and oil revenues in the global power equation, it is inevitable that depressed oil prices will doom the current global political order, writes Michael T. Klare, a professor of peace and world security studies at Hampshire College. Political turmoil is already raging across the oil heartlands of the planet – and the tremors from the oil pricequake have yet to reach their full magnitude, notes Klare. As 2015 drew to a close, many in the global energy industry were praying that the price of oil would bounce back from the abyss, restoring the petroleum-centric world of the past half-century. All evidence, however, points to a continuing depression in oil prices in 2016 – one that may, in fact, stretch into the 2020s and beyond. Given the centrality of oil (and oil revenues) in the global power equation, this is bound to translate into a profound shakeup in the political order, with petroleum-producing states from Saudi Arabia to Russia losing both prominence and geopolitical clout. To put things in perspective, it was not so long ago – in June 2014, to be exact – that Brent crude, the global benchmark for oil, was selling at $115 per barrel. Energy analysts then generally assumed that the price of oil would remain well over $100 deep into the future, and might gradually rise to even more stratospheric levels. Such predictions inspired the giant energy companies to invest hundreds of billions of dollars in what were then termed “unconventional” reserves: Arctic oil, Canadian tar sands, deep offshore reserves, and dense shale formations. It seemed obvious then that whatever the problems with, and the cost of extracting, such energy reserves, sooner or later handsome profits would be made. It mattered little that the cost of exploiting such reserves might reach $50 or more a barrel. Read More here
14 January 2016, New York Times, In Climate Move, Obama Halts New Coal Mining Leases on Public Lands. The Obama administration announced on Friday a halt to new coal mining leases on public lands as it considers an overhaul of the program that could lead to increased costs for energy companies and a slowdown in extraction. “Given serious concerns raised about the federal coal program, we’re taking the prudent step to hit pause on approving significant new leases so that decisions about those leases can benefit from the recommendations that come out of the review,” said Interior Secretary Sally Jewell. “During this time, companies can continue production activities on the large reserves of recoverable coal they have under lease, and we’ll make accommodations in the event of emergency circumstances to ensure this pause will have no material impact on the nation’s ability to meet its power generation needs.” The move represents a significant setback for the coal industry, effectively freezing new coal production on federal lands and sending a signal to energy markets that could turn investors away from an already reeling industry. President Obama telegraphed the step in his State of the Union address on Tuesday night when he said “I’m going to push to change the way we manage our oil and coal resources so that they better reflect the costs they impose on taxpayers and our planet.” Read More here
