11 June 2015, Energy Post, Solar power passes 1% global threshold: Solar power now covers more than 1% of global electricity demand. In three countries in Europe – Italy, Germany and Greece – solar PV supplies more than 7% of electricity demand. This is reported by Solar Power Europe (previously EPIA – European Photovoltaic Industry Association). China is the fastest growing market. Research company GlobalData has adjusted projected new capacity in China for 2015 upwards. Last year 40 GW of new solar capacity was installed worldwide, compared to 38.4 GW in 2013, notes Solar Power Europe (SPE) in its Global Market Outlook 2015-2019. Cumulative capacity is now 178 GW. In terms of generation, this is equivalent to 33 coal-fired power stations of 1 GW, notes SPE. In Europe last year 7 GW was installed, which was less than in 2013. The UK was the fastest growing market, contributing 2.4 GW. Europe now installs less solar power capacity than China or Japan individually, but still more than the US. However, Europe is still the world’s largest player with more than 88 GW installed at the end of 2014. Read More here

9 June 2015, Renew Economy, How South Australia coped without any baseload power: South Australia’s electricity system was put the test over the long weekend when the state’s only baseload power contributor, the brown coal Northern power station near Augusta, suddenly tripped and stopped providing power. The incident was caused by a fire that caused several injuries, including one serious injury to a worker still in hospital. This is not the first time that South Australia has been without baseload coal power, of course. Northern was mothballed for nearly a year because of the declining economics of the coal generator. The difference with this event is that it came unannounced. While declines and increases in the output of wind and solar are quite predictable, sudden outages in baseload fossil fuels are not, which is why the energy system needs a large amount of redundancy to support large centralised generation.

9 June 2015, Science Daily, Land management practices to become important as biofuels use grows: The handling of agricultural crop residues appears to have a large impact on soil’s ability to retain carbon, making land management practices increasingly important, especially under a scenario where cellulosic materials become more heavily used as a feedstock for ethanol production, according to a recently published study led by researchers at the U.S. Department of Energy’s Argonne National Laboratory. “Plants and soil are carbon sinks,” said Argonne climate scientist Beth Drewniak, who led the study. “Soils lock carbon away for long periods of time. But when plant residues are harvested, not only are inputs of carbon and other nutrients to soil lost, but decomposition is accelerated, causing soils to lose additional carbon.” Read More here
5 June 2015, Truth Dig, Big Oil Soon to be Extinct: What do Big Oil and whale oil have in common? According to Amory B. Lovins, chairman and chief scientist of the sustainability-focused Rocky Mountain Institute, Big Oil is soon to follow whale oil’s downward trajectory toward extinction. At the Ceres Conference 2015 for sustainable business, Lovins challenged big businesses to rethink the outdated belief that investing in fossil fuels remains the safest way to get rich (dolphins, seabirds and humanity be damned). At first look, Lovins appears to be a nerdy, middle-aged scientist in a suit, but once he starts talking, it becomes clear that he’s actually a brilliant revolutionary. Lovins’ message hasn’t changed much in the four decades he’s been doggedly trying to get the world to embrace renewable energy, but he’s accumulated more data to prove his point to a host of unlikely converts, from communist China to Arab sheiks and presidents of companies like Texaco. Even if you don’t care much about the environment, Lovins makes the case that you’d be economically foolish not to invest in renewable energy, because green technology today is akin to the discovery of petroleum and its effect on the whaling industry of the 19th century.
