13 April 2016, Vox, Why Peabody Energy, the world’s largest coal company, just went bankrupt. The US coal industry is imploding. And here’s the biggest casualty yet: Peabody Energy, the world’s largest private-sector coal company, filed for Chapter 11 bankruptcy in St. Louis on Wednesday. It’s hard to overstate what a seismic shift this is. Peabody has been a giant in the mining industry seemingly forever, after starting out in Chicago in 1880 with just a wagon and two mules. A decade ago, coal provided fully half of America’s electricity, much of it dug up by Peabody in Illinois, Kentucky, Wyoming, Colorado. At its peak in 2008, the company had a market cap of $20 billion, supplying coal to 26 countries worldwide. But then came the fall. The rise of fracking and cheap shale gas in the United States, coupled with stricter environmental regulations, has helped push hundreds of coal-fired power plants out of business in recent years. US coal production has nosedived from 1.17 billion metric tons in 2008 to just 752.5 million in 2016. Coal consumption in China, another crucial market, has also cooled off of late. Between 2012 and 2015, Peabody laid off more than 20 percent of its global workforceand started closing some of its US mines. Today, the company is saddled with $10.1 billion in debt and its future looks much bleaker than it once did. Hence the bankruptcy filing. Read More here

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
3 April 2016, The Guardian, Adani’s Carmichael coalmine leases approved by Queensland. Decision a major step forward for $21.7bn coalmine, which green groups warn will fuel global warming and compound threats to Great Barrier Reef. The Queensland government has granted three mining leases for Adani’s multi-billion dollar Carmichael coalmine, which will be the largest in Australia. Environmental groups say the mine will fuel global warming and compound threats to the world heritage-listed Great Barrier Reef amid one of its worst coral bleaching events on record. The premier, Annastacia Palaszczuk, and the mines minister, Anthony Lynham, made the announcement in Mackay on Sunday. The premier put the value of the project at $21.7bn, and said the approvals meant thousands of new jobs were now a step closer to reality. “Some approvals are still required before construction can start, and ultimately committing to the project will be a decision for Adani,” Palaszczuk said. “However, I know the people of north and central Queensland will welcome this latest progress for the potential jobs and economic development it brings closer for their communities.” She said stringent conditions would ensure the health of the reef and the environment, and the interests of traditional owners.

31 March 2016, Energy Post, The end of coal: good riddance or dangerous gamble? Scotland has become the first part of the UK to stop burning coal to supply electricity following the closure of Longannet, its largest power station, on March 24. According to Paul Younger, Professor of Energy Engineering at University of Glasgow, the closure of coal-fired power plants in the UK may lead to serious problems with voltage control. Prepare for power interruptions and flickering lights. The closure of Longannet is a sign of the times, with the rest of the UK’s coal-fired power stations on death row after energy secretary Amber Rudd announced late last year that they will all be forced to close by 2025. For many reasons, it is hard to mourn the demise of coal-fired power. Around 12,000 miners are killed around the world each year, most of them digging for coal; abandoned mines cause widespread water pollution; and coal-fired plants pollute the air with the likes of nitrogen and sulphur compounds, as well as the highest greenhouse-gas emissions of any major source of energy generation. In the absence of carbon capture and storage, a technology which would be ready more quickly if the government backed it properly, plant closure may therefore seem sensible – even while we should help those that lose their jobs and regret the loss of skills from the workforce.If we are going to manage without Longannet and all the other gas-fired and coal-fired power stations, we would need at least 970 GWh of storage – more than a hundred pumped hydropower stations of comparable size to those we already have. That would be all there was to say were it not for a few harsh realities of electricity supply. There are two reasons why coal-fired power plants have survived so long. Coal is cheap; only since the US shale-gas boom has it been consistently beaten on price. And coal-fired plants are particularly suited to providing power on demand at short notice, as well as providing crucial stabilisation services for frequency and voltage across the grid.
