24 February 2016, Science Daily, Consumers have huge environmental impact. We like to blame the government or industries for the Earth’s problems, but what we buy makes a big difference. The world’s workshop — China — surpassed the United States as the largest emitter of greenhouse gases on Earth in 2007. But if you consider that nearly all of the products that China produces, from iPhones to tee-shirts, are exported to the rest of the world, the picture looks very different. “If you look at China’s per capita consumption-based (environmental) footprint, it is small,” says Diana Ivanova, a PhD candidate at Norwegian University of Science and Technology’s Industrial Ecology Programme. “They produce a lot of products but they export them. It’s different if you put the responsibility for those impacts on the consumer, as opposed to the producer.” That’s exactly what Ivanova and her colleagues did when they looked at the environmental impact from a consumer perspective in 43 different countries and 5 rest-of-the-world regions. Their analysis, recently published in the Journal of Industrial Ecology, showed that consumers are responsible for more than 60 per cent of the globe’s greenhouse gas emissions, and up to 80 per cent of the world’s water use. “We all like to put the blame on someone else, the government, or businesses,” Ivanova says. “But between 60-80 per cent of the impacts on the planet come from household consumption. If we change our consumption habits, this would have a drastic effect on our environmental footprint as well.” The analysis allowed Ivanova and her colleagues to see that consumers are directly responsible for 20 per cent of all carbon impacts, which result from when people drive their cars and heat their homes. But even more surprising is that four-fifths of the impacts that can be attributed to consumers are not direct impacts, like the fuel we burn when we drive our cars, but are what are called secondary impacts, or the environmental effects from actually producing the goods and products that we buy.

25 January 2016, Renew Economy, Tasmania grid struggles with drought, bushfires, lost connection. Tasmania’s electricity grid is facing its biggest challenge in years, with its hydro storage about to fall to its lowest levels ever, bushfires forcing the closure of some power facilities, and a faulty cable cutting the connection between the island and the country’s main electricity grid. The Apple Isle’s main source of electricity – hydro power – is being challenged by its driest ever spring, pushing reserves down to just 18.9 per cent. The lowest level ever is 16.5 per cent, reached in 2007, but overall storage levels are predicted to fall to a low of 14 per cent by the end of March – if normal rainfall patterns resume. At current rates, however, some fear they may fall below those levels, although there has been some light rain in recent days. To make matters worse, the Basslink cable linking the island’s grid to the mainland has been cut by technical problems, and will probably remain closed for another two months, while the raging bushfires have threatened power lines and forced the temporary closure of at least four hydro plants. “These circumstances are extraordinary and unprecedented,” Premier Will Hodgman and energy minister Matthew Groom said in a joint statement late last week. “It will be tough, but we will get through it.” To address the issue, the government has had to bring its Tamar Valley gas power generator – scheduled for permanent closure last year – out of mothballs. That has provided 280MW of added capacity, but the government is now looking to bring another 105MW of gas and diesel power back into the system to hedge against further depletion of its hydro resources.

22 January 2016, Climate News Network, Plutonium’s global problems are piling up. Increasing worldwide stockpiles of surplus plutonium are becoming a political embarrassment, a worrying security risk, and a hidden extra cost to the nuclear industry. Two armed ships set off from the northwest of England this week to sail round the world to Japan on a secretive and controversial mission to collect a consignment of plutonium and transport it to the US. The cargo of plutonium, once the most sought-after and valuable substance in the world, is one of a number of ever-growing stockpiles that are becoming an increasing financial and security embarrassment to the countries that own them. So far, there is no commercially viable use for this toxic metal, and there is increasing fear that plutonium could fall into the hands of terrorists, or that governments could be tempted to use it to join the nuclear arms race. All the plans to use plutonium for peaceful purposes in fast breeder and commercial reactors have so far failed to keep pace with the amounts of this highly-dangerous radioactive metal being produced by the countries that run nuclear power stations. The small amounts of plutonium that have been used in conventional and fast breeder reactors have produced very little electricity − at startlingly high costs. Read More here
28 December 2015, Climate News network, Markets cannot solve the climate crisis. How did we get to where we are now? “Free range” capitalism could be the explanation for climate change, and needs taming, says one writer. It may not be polite to mention Karl Marx in America, but leading thinkers on the left think that capitalism may be the cause of climate change, and that to save the planet the system needs fundamental reform. According to a new book the profit motive, which drives capitalism above all other considerations, forces it to extract everything from the planet that will generate a surplus, at the expense of real benefits to humans and ecosystems. Fossil Capital: the Rise of Steam Power and the Roots of Global Warming, by Andreas Malm, out in hardback from Verso in January 2016, analyses capitalism’s role in global warming by delving into its past. The book builds on the work of Naomi Klein’s 2014 This Changes Everything: Capitalism vs the Climate. Both ask whether catastrophic climate change can be averted without at least a major makeover – or the outright elimination – of capitalism. Malm, a professor of human ecology at Sweden’s Lund University, starts with James Watt’s patenting of the rotating steam engine in 1784. This was also the first year that rising carbon dioxide and methane levels were observed in polar ice. First Malm attacks the accepted theories of David Ricardo and Thomas Malthus. who developed and reinforced the capitalist notion that markets are the cure for all social ills. He shows that mills adopted coal power instead of water only because it enabled mill owners to move to populated areas to find docile and skilled workers, who were in short supply in the countryside. More biddable Coal enabled this move because, once out of the ground, it is highly portable. The machines, of course, eliminated many jobs and made others both simpler and more difficult. Owners started hiring women and children because they were easier to control than adult men. Read more here
