23 August 2016, The Conversation, Australia’s new focus on gas could be playing with fire. Gas is back on Australia’s agenda in a big way. Last week’s meeting of state and federal energy ministers in particular saw an extraordinary focus on gas in the electricity sector. While the meeting promised major reform for the energy sector, the federal energy and environment minister, Josh Frydenberg, highlighted the need for more gas supplies and “the growing importance of gas as a transition fuel as we move to incorporate more renewables into the system”. Gas is certainly a lower-carbon energy source than coal, but gas prices have soared as Australia begins shipping gas overseas. So what might this mean for energy and climate policy? Rising gas. In 2013-14 natural gas-fired generation rose to account for 22% of Australia’s electricity generation, although the figure falls to 12% in the National Electricity Market (NEM), which excludes Western Australia and the Northern Territory, both of which use a large amount of gas. Among the NEM states, South Australia relies the most on gas-powered generation. This means that gas generators generally set the state’s average electricity price, which has usually been higher than those in the eastern states. Average electricity prices in Victoria, New South Wales and Queensland tend to be set more often by coal power generators than by gas. Read More here

28 June 2016, DESMOG, Obama Admin Approved Over 1,500 Offshore Fracking Permits in Gulf of Mexico and Mainstream Media Has Ignored It. On June 24, the independent news website TruthOut broke a doozy of a story: the Obama Administration has secretly approved over 1,500 instances of offshore hydraulic fracturing (“fracking”) in the Gulf of Mexico, including during the Deepwater Horizon offshore spill disaster. Albeit released on a Friday, a day where many mainstream media reporters head out of the office early and venture to late-afternoon and early-evening Happy Hour specials at the bars, the TruthOut story has received deafening silence by the corporate-owned media apparatus. Google News, Factiva and LexisNexis searches reveal that not a single mainstream media outlet has covered the story. TruthOut got its hands on the story via documents provided by the Center for Biological Diversity (CBD). CBD explained inpress release that they “obtained the information following an agreement that settled a lawsuit challenging the federal Bureau of Ocean Energy Management’s and Bureau of Safety and Environmental Enforcement’s failure to disclose documents regarding the scope of offshore fracking in the Gulf under the Freedom of Information Act.” CBD also has published a list of all of the instances of offshore fracking in the Gulf of Mexico provided to it by BOEM, both inlist-form and in visual map form.

13 April 2016, Inside Climate News, CO2’s Role in Global Warming Has Been on the Oil Industry’s Radar Since the 1960s. Historical records reveal early industry concern with air pollutants, including smog and CO2, and unwanted regulation. The oil industry’s leading pollution-control consultants advised the American Petroleum Institute in 1968 that carbon dioxide from burning fossil fuels deserved as much concern as the smog and soot that had commanded attention for decades. Carbon dioxide was “the only air pollutant which has been proven to be of global importance to man’s environment on the basis of a long period of scientific investigation,” two scientists from the Stanford Research Institute (SRI) told the API. This paper, along with scores of other publications, shows that the risks of climate change were being discussed in the inner circles of the oil industry earlier than previously documented. The records, unearthed from archives by a Washington, D.C. environmental law organization, the Center for International Environmental Law (CIEL), reveal that the carbon dioxide question—an obscure corner of research for much of the 20th century—had been closely studied since the 1950s by some oil company researchers.

7 April 2016, Energy Post, Wind and solar’s Achilles heel: what the methane meltdown at Porter Ranch means for the energy transition. Utitlity-scale wind and solar power are typically backed up on-site by gas peakers, or backed up indirectly by gas-fired power plants. These gas plants lead to significant greenhouse gas emissions in the form of methane. So at what point does a renewable-plus-gas combination become worse for the climate than coal-fired power? Mike Conley and Tim Maloney, long-time members of the Thorium Energy Alliance, have calculated what they call a “Worth-It Treshold” that gives the answer. And they conclude as things stand, natural gas isn’t a bridge to a sustainable future.“We need about 3,000 feet of altitude, we need flat land, we need 300 days of sunlight, and we need to be near a gas pipe. Because for all of these big utility-scale solar plants – whether it’s wind or solar – everybody is looking at gas as the supplementary fuel. The plants that we’re building, the wind plants and the solar plants, are gas plants.” 1– Robert F. Kennedy, Jr. Environmental activist, Member of the board of Bright Source, developers of the Ivanpah Solar Station, Nevada, a 392 MW (peak) concentrated solar plant. Part One Natural Gas – the polite term for methane The methane leak in the Los Angeles suburb of Porter Ranch is America’s worst environmental disaster since the 2010 Deepwater Horizon oil spill in the Gulf of Mexico. But even more troubling is the larger issue of “fugitive” methane, and what it means for our growing reliance on wind and solar energy. Burning methane for energy produces about half the CO2 of coal, which is a good thing. But fugitive methane – the gas that leaks before it can be burned – is a powerful greenhouse gas, with 84X the Global Warming Potential (GWP) of CO2. The big idea behind wind and solar farms is to fight global warming by reducing greenhouse gases. But since most of a farm’s power is actually generated by gas, the rationale for a massive build-out of utility-scale wind and solar hinges on the issue of fugitive methane. That rationale just had a major meltdown at Porter Ranch. Read More here
