Un-addicted to Coal? United States


The U.S. Environmental Protection Agency [released on June 2, 2014}the Clean Power Plan proposal, which for the first time cuts carbon pollution from existing power plants, the single largest source of carbon pollution in the United States…

Power plants account for roughly one-third of all domestic greenhouse gas emissions in the United States. While there are limits in place for the level of arsenic, mercury, sulfur dioxide, nitrogen oxides, and particle pollution that power plants can emit, there are currently no national limits on carbon pollution levels.

[Goals to be achieved by 2030]

· Cut carbon emission from the power sector by 30 percent nationwide below 2005 levels, which is equal to the emissions from powering more than half the homes in the United States for one year;

· Cut particle pollution, nitrogen oxides, and sulfur dioxide by more than 25 percent as a co-benefit;

· Avoid up to 6,600 premature deaths, up to 150,000 asthma attacks in children, and up to 490,000 missed work or school days—providing up to $93 billion in climate and public health benefits;

· Shrink electricity bills roughly 8 percent by increasing energy efficiency and reducing demand in the electricity system.

The Clean Power Plan will be implemented through a state-federal partnership under which states identify a path forward using either current or new electricity production and pollution control policies to meet the goals of the proposed program. The proposal provides guidelines for states to develop plans to meet state-specific goals to reduce carbon pollution and gives them the flexibility to design a program that makes the most sense for their unique situation. States can choose the right mix of generation using diverse fuels, energy efficiency and demand-side management to meet the goals and their own needs. It allows them to work alone to develop individual plans or to work together with other states to develop multi-state plans.

Also included in today’s proposal is a flexible timeline for states to follow for submitting plans to the agency—with plans due in June 2016, with the option to use a two-step process for submitting final plans if more time is needed. States that have already invested in energy efficiency programs will be able to build on these programs during the compliance period to help make progress toward meeting their goal.

The Fatal Attraction to Coal: World


Coal is cheap and simple to extract, ship and burn. It is abundant: proven reserves amount to 109 years of current consumption… Just as this wonder-fuel once powered the industrial revolution, it now offers the best chance for poor countries wanting to get rich.  Such arguments are the basis of a new PR campaign launched by Peabody, the world’s largest private coal company (which unlike some rivals is profitable, thanks to its low-cost Australian mines). And coal would indeed be a boon, were it not for one small problem: it is devastatingly dirty. Mining, transport, storage and burning are fraught with mess, as well as danger. Deep mines put workers in intolerably filthy and dangerous conditions. But opencast mining, now the source of much of the world’s coal, rips away topsoil and gobbles water. Transporting coal brings a host of environmental problems.

The increased emissions of carbon dioxide from soaring coal consumption threaten to fry the planet…he CO2 makes the oceans acid; burning coal also produces sulphur dioxide, which makes buildings crumble and lungs sting, and other toxic chemicals. By some counts, coal-fired power stations emit more radioactivity than nuclear ones. They release tiny, lethal particulates. Per unit generated, coal-fired stations cause far more deaths than nuclear ones, and more even than oil-fired ones.

But poverty kills people too, and slow growth can cost politicians their jobs. Two decades of environmental worries are proving only a marginal constraint on the global coal industry. The International Energy Agency has even predicted that, barring policy changes, coal may rival oil in importance by 2017… As countries get richer they tend to look for alternatives—China is scrambling to curb its rising consumption. But others, such as India and Africa, are set to take up the slack

America’s gas boom has prompted its coal miners to seek new export markets, sending prices plunging on world markets. So long as consumers do not pay for coal’s horrible side-effects, that makes it irresistibly cheap. In Germany power from coal now costs half the price of watts from a gas-fired power station. … Its production of power from cheap, dirty brown coal (lignite) is now at 162 billion kilowatt hours, the highest since the days of the decrepit East Germany.  Japan, too, is turning to coal in the wake of the Fukushima nuclear disaster. On April 11th the government approved a new energy plan entrenching its role as a long-term electricity source.

International coal companies face two worries. One is that governments may eventually impose punitive levies, tariffs and restrictions on their mucky product. The other is the global glut. Prices for thermal coal (the kind used for power and heating) are at $80-85 a tonne, which barely covers the cost of capital. Some Australian producers are even mining at a loss, having signed freight contracts with railways and ports that make them pay for capacity whether they use it or not….

Perhaps the biggest hope for all involved in the coal industry is technology. Mining and transporting coal will always be messy, but this could be overlooked were it burned cheaply and cleanly. Promising technologies abound: pulverising coal, extracting gas from it, scrubbing emissions and capturing the CO2. But none of these seems scalable in the way needed to dent the colossal damage done by coal. And all require large subsidies—from consumers, shareholders or taxpayers.

A $5.2 billion taxpayer-supported clean-coal plant in Mississippi incorporates all the latest technology. But at $6,800 per kilowatt, it will be the costliest power plant yet built (a gas-fired power station in America costs $1,000 per kW). At those prices, coal is going to stay dirty.

US Coal Exports to Asia: Coal States v. Coastal States

Energy wars in America’s West are nothing new. But the rancour aroused by the coal-export proposal[from Montana and Wyoming to Japan, India and China through new ports built in Oregon and Washington] has become as toxic as a four-chimney belcher. Coal states accuse coastal ones of high-minded NIMBYism. Campaigners say corporations have a primeval attitude to the environment. Cities and counties lock horns over jobs and trade. Everyone accuses everyone else of bad faith, basic innumeracy and, in some cases, black ops.

Local objections focus on the trains that would carry coal to the Gateway Pacific Terminal. At capacity, 18 trains a day would run to and from the facility: nine bearing coal and nine returning empty to the mines. BNSF Railway, one of the project’s backers, says little new rail infrastructure would be needed, as traffic remains below its 2006 peak. Sceptics doubt that, and say the bill will be dumped on taxpayers.

Even without new tracks there is plenty to object to. The coal trains would rattle through central Seattle (the empties could return via other tracks, says BNSF), potentially gumming up roads already groaning with congestion. “I don’t want this terminal built,” says Mike McGinn, the mayor. In Bellingham, a group called Whatcom Docs (named for the surrounding county) worries about trains spewing diesel particulates. Others fret about coal dust flying off the trains; the Sierra Club, an environmental NGO, is threatening to sue BNSF for polluting Washington’s waterways.

The Golden Age of Coal

Yangzhou industrial area, China

Coal-fired power stations provide two-fifths of the world’s electricity, and there are ever more of them. In the doubling of the world’s electricity production over the past decade, two-thirds of the increase came from coal. At these rates, coal will vie with oil as the world’s largest source of primary energy within five years. As recently as 2001, it was not much more than half as important as oil

The main factor has been the unslakable thirst for energy in China, which in 2011 overtook America as the world’s biggest electricity producer. In 2001, according to the International Energy Agency, a club of rich nations, Chinese coal demand was about 600m tonnes of oil equivalent (25 exajoules). By 2011 China’s coal demand had tripled—a rise from two-thirds of the energy America gets from oil to twice that amount. China’s domestic coal industry produces more primary energy than Middle Eastern oil does.

Other developing economies are just as keen on coal, if not yet on such a grand scale. In India, producing 650 terawatt hours of electricity in 2010 took 311m tonnes of oil equivalent, and the power sector’s coal demand is growing at around 6% a year. The IEA reckons India could surpass America as the world’s second-largest coal consumer by 2017.

Meanwhile in Europe, which likes to see itself as a world leader on climate, they are using more and more of the stuff.

America’s coal business, like the rest of the country’s energy industry, has been upended by the advent of shale gas, now available in unforeseen quantities at unforeseen prices. In April 2012 the price fell below $2 per million British thermal units, or Btus ($7 per megawatt hour). This has made gas increasingly attractive to power companies, which have been switching away from coal in increasing numbers.

The decline of coal.. will be protracted. Coal-fired power stations are built to last—the oldest plant currently operating was built in the 1930s—so unless new rules force them to close, they will be retired gradually. By 2017 or so, reckons Brattle Group, a consultancy, coal use will stabilise again, as gas demand finally makes gas prices dearer than coal. Coal may be down in America. But it is not yet out
