Archive of Past Articles for Chapter 3

2011 April 11. Studies Say Natural Gas Has Its Own Environmental Problems. By Tom Zeller Jr., The New York Times. Excerpt: Natural gas, with its reputation as a linchpin in the effort to wean the nation off dirtier fossil fuels and reduce global warming, may not be as clean over all as its proponents say…They suggest that the rush to develop the nation’s vast, unconventional sources of natural gas is logistically impractical and likely to do more to heat up the planet than mining and burning coal…
…The problem, the studies suggest, is that planet-warming methane, the chief component of natural gas, is escaping into the atmosphere in far larger quantities than previously thought…

2011 Spring. A Risky Proposition. By Barbara Freese,  Catalyst, Union of Concerned Scientists. Excerpt: Our nation depends on coal for almost half its electricity, even though most coal-fired power plants are decades old (some dating back to the Eisenhower administration), and impose staggering costs on our health and environment. Rather than shifting away from coal, many utilities around the country are spending, or planning to spend, huge sums to retrofit old coal plants, hoping to pass the costs on to ratepayers….
…We summarize the changing economic risk factors that no would-be investor in coal can afford to ignore….

2010 Nov 22. Nations That Debate Coal Use Export It to Feed China’s Need. By Elisabeth Rosenthal, The NY Times. Excerpt: ...In the last few years, long-distance international coal exports have been surging because of China’s galloping economy, which now burns half of the six billion tons of coal used globally each year.
As a result, not only are the pollutants that developed countries have tried to reduce finding their way into the atmosphere anyway, but ships chugging halfway around the globe are spewing still more.
And the rush to feed this new Asian market has helped double the price of coal over the past five years, leading to a renaissance of mining and exploration in many parts of the world…
…The conflict between environmental and trade concerns is gaining momentum in the United States and Canada as well as Australia…

2010 October 25. Navajos Hope to Shift From Coal to Wind and Sun. By Mireya Navarro, The New York Times. Excerpt: …Seeking to reverse years of environmental degradation and return to their traditional values, many Navajos are calling for a future built instead on solar farms, ecotourism and microbusinesses…

2010 August 2. Tracing Oil Reserves to Their Tiny Origins. By William J. Broad, The New York Times. Excerpt: …Today, a principal tenet of geology is that a vast majority of the world’s oil arose not from lumbering beasts on land but tiny organisms at sea. It holds that blizzards of microscopic life fell into the sunless depths over the ages, producing thick sediments that the planet’s inner heat eventually cooked into oil. It is estimated that 95 percent or more of global oil traces its genesis to the sea.
…As land reservoirs dry up, oil geologists say, the high costs and potential risks of offshore drilling will seem less onerous and more acceptable… Whatever the future importance of oil, offshore beds are the most likely new sources.
…The secret of the oil story turned out to be understanding how the bygone oceans, ancient seas and smaller bodies of water produced complex environmental conditions that raised the prevalence of microscopic life and ensured its deep burial, producing what eventually became the earth’s main oil reservoirs.
…Oil production begins when surface waters become so rich in microscopic life that the rain of debris outpaces decay on the seabed. The result is thickening accumulations of biologic sludge.
…The history of the Gulf of Mexico shows how many environmental factors came together to produce huge oil reserves. Perhaps most important, the big rivers and waterways of North America sent rich flows of nutrients into the ancient gulf, much as the Mississippi River does today. …The ancient body was [also] largely cut off from the diluting influences of the wider global sea, concentrating the nutrients and mud.

2010 June 16. Far From Gulf, a Spill Scourge 5 Decades Old. By Adam Nossiter, The NY Times. Excerpt: …BODO, Nigeria — Big oil spills are no longer news in this vast, tropical land. The Niger Delta, where the wealth underground is out of all proportion with the poverty on the surface, has endured the equivalent of the Exxon Valdez spill every year for 50 years by some estimates. The oil pours out nearly every week, and some swamps are long since lifeless.
…Perhaps no place on earth has been as battered by oil, experts say, leaving residents here astonished at the nonstop attention paid to the gusher half a world away in the Gulf of Mexico. It was only a few weeks ago, they say, that a burst pipe belonging to Royal Dutch Shell in the mangroves was finally shut after flowing for two months: now nothing living moves in a black-and-brown world once teeming with shrimp and crab.
…As many as 546 million gallons of oil spilled into the Niger Delta over the last five decades, or nearly 11 million gallons a year, a team of experts for the Nigerian government and international and local environmental groups concluded in a 2006 report. By comparison, the Exxon Valdez spill in 1989 dumped an estimated 10.8 million gallons of oil into the waters off Alaska.
…On the beach at Ibeno, the few fishermen were glum. Far out to sea oil had spilled for weeks from the Exxon Mobil pipe. “We can’t see where to fish; oil is in the sea,” Patrick Okoni said.
...“We don’t have an international media to cover us, so nobody cares about it,” said Mr. Mbong, in nearby Eket. “Whatever cry we cry is not heard outside of here.”

2010 May 28. Scientists Build Case for Undersea Plumes. By Justin Gillis, The NY Times. Excerpt: …That higher estimate only added to the sense among academic scientists that much of the oil must be hovering in the deep sea, instead of surfacing. The goal of the researchers aboard the Walton Smith was to nail the existence of such deep-sea plumes beyond any doubt.
…It will take weeks of laboratory work to confirm with certainty that the plumes are made of oil droplets, or more likely, some complex mixture of oil and natural gas. If that idea holds up, the existence of these undersea plumes may well turn out to be the major scientific discovery of the great oil spill of 2010.
…That, Dr. Joye said, was most likely because bacteria were ramping up to consume the oil and gas — a good thing, over all, but it was creating a heavy demand for oxygen and other nutrients. Aside from the toxic effect of the oil, the declining oxygen was a potential threat to sea life.

2010 May 18 Burning Coal, Burning Cash: States That Import the Most Coal.  Union of Concerned Scientists. Excerpt: The cost of importing coal is a major drain on the economies of many states that rely heavily on coal-fired power. UCS's analysis, Burning Coal, Burning Cash, shows the scale of this annual drain on state economies, and suggests how they can keep more of those funds in-state through investments in energy efficiency and homegrown renewable energy.
We have ranked states' dependence on imported coal in each of six categories.
...You can download information specific to each of these 24 states from the list below.

2009 May 10. China Outpaces U.S. in Cleaner Coal-Fired Plants. By Keith Bradsher, The NY Times. Excerpt: TIANJIN, China — China’s frenetic construction of coal-fired power plants has raised worries around the world about the effect on climate change. China now uses more coal than the United States, Europe and Japan combined, making it the world’s largest emitter of gases that are warming the planet.
But largely missing in the hand-wringing is this: China has emerged in the past two years as the world’s leading builder of more efficient, less polluting coal power plants, mastering the technology and driving down the cost.
While the United States is still debating whether to build a more efficient kind of coal-fired power plant that uses extremely hot steam, China has begun building such plants at a rate of one a month....

2009 March. Physics in the oil sands of Alberta. By Murray Gray, Zhenghe Xu, and Jacob Masliyah, Physics Today. Excerpt: The recent spike in the price of oil to over US$140 per barrel focused worldwide attention on the need for more diverse supplies of fuel from unconventional sources and renewable resources. The oil sands of Alberta, the largest source of unconventional fuel for North America, are also the largest petroleum deposit on Earth. Sometimes called tar sands, they contain an estimated 2.5 trillion barrels of crude oil over an area of more than 140 000 square kilometers, but that oil, called bitumen, is too viscous to be extracted by conventional drilling....
Material from a typical commercially viable oil-sands deposit ... contains 9%–13% bitumen, 3%–7% water, and 80%–85% mineral solids. Of the solids, 15%–30% are fine particles, predominantly clays, less than 44 µm in diameter. The challenge in production is to separate the bitumen not only from the sand grains but also from the micron- and submicron-sized clay particles. Alberta’s bitumen reserves...are estimated at 172 billion to 315 billion barrels. In comparison, the crude-oil reserves in Saudi Arabia are estimated at 264 billion barrels....
...Relatively shallow oil-sands deposits are most economically accessed by mining operations in which the overlying dirt, or overburden, is removed by massive trucks and shovels to expose the oil sands. The goal of mining operations is to remove overburden and extract oil-sands ore in large quantities, process the ore using as little energy as possible to recover at least 90% of the bitumen, and then reclaim the mines to leave a landscape that supports vegetation and wildlife. The technical challenges of the process are related to the physics of oil-sands components, and solving them involves fluid–particle physics, chemistry, and interfacial science....

2009 Feb 14. Is America Ready to Quit Coal? By MELANIE WARNER, NY Times. With regulations to address climate change looming, coal power looks increasingly expensive. Excerpt: Last May, protesters took over James E. Rogers's front lawn in Charlotte, N.C., unfurling banners declaring "No new coal" and erecting a makeshift "green power plant" - which, they said in a press release, was fueled by "the previously unexplored energy source known as hot air, which has been found in large concentrations" at his home.
...With concerns over climate change intensifying, electricity generation from coal, once reliably cheap, looks increasingly expensive in the face of the all-but-certain prospect of regulations that would impose significant costs on companies that emit large amounts of carbon dioxide and other greenhouse gases. As a result, utilities' plans for new coal plants are being turned down left and right. In the last two-and-a-half years, plans for 83 plants in the United States have either been voluntarily withdrawn or denied permits by state regulators. The roughly 600 coal-fired power plants in the United States are responsible for almost one-third of the country's total carbon emissions, ....
...getting more and more of our energy from squeaky-clean sources like wind, solar and biomass sounds like a great idea, but whether renewables can keep the lights on and our iPods charged remains an open question.
THE coal industry is aware of all of these issues and is fighting back. An industry-financed group called the American Coalition for Clean Coal Electricity spent $38 million last year informing Americans, via TV and newspaper ads, that coal is the source of 50 percent of their electricity, that it is an abundant domestic resource and, most importantly, that there is the promise of "clean," or carbon-free, coal. ...The problem is that the technology, called carbon capture and storage, is still being developed and could make electricity generated by coal more expensive than power from other sources.
..."There are 16 gigawatts of new coal-fired generation coming online in the next few years," said Kevin Book, an energy policy analyst at FBR Capital Markets. "They may well be the last plants." Mr. Rogers, 61, may adhere to the pro-coal sentiments of many of his peers, but he is hardly a typical captain of the energy industry. Five years ago, he began advocating for climate change legislation at a time when some companies were still saying human activity had nothing to do with global warming. Mr. Rogers, a native of Birmingham, Ala., considers himself an environmentalist and calls his decision to move forward with the new plant... a difficult one. ...This fall, the 150-foot smokestack at the company's Mountaineer coal plant in New Haven, W.Va., will be outfitted with technology that uses chilled ammonia to trap carbon dioxide. The greenhouse gas will then be turned into a liquid and injected into the ground. It will be the first such project that will both capture and store carbon from an existing plant....

2008 Sept. New Coal Technologies. MuseLetter 197 by Richard Heinberg. Excerpt: For coal, the future of both extraction and consumption depends on new technology. If successfully deployed, innovative technologies could enable the use of coal that is unminable by gasifying it underground; reduce coal's carbon emissions; or allow coal to take the place of natural gas or petroleum. Without them, coal simply may not have much of a future. Are these technologies close to development? Are they economical? Will they work? The technologies discussed in this chapter go by some rather unwieldy names, and so we shall call them by their customary acronyms: Coal-to-Liquids (CTL), Underground Coal Gasification (UCG), Integrated Gasification Combined Cycle (IGCC), and Carbon Capture and Storage (CCS).
Many energy experts believe that these technologies may largely define the world's energy path for the next few decades. ...In most instances (with the exception of underground gasification, or UCG), gasification is accomplished in-of all things-a gasifier, into which coal, water, and air are fed. Heat and pressure reduce the coal to "synthesis gas" or "syngas"-a mixture of carbon monoxide and hydrogen, along with solid waste byproducts consisting of ash and slag, which can be used in making concrete or roadbeds.
...to turn coal into a synthetic liquid fuel to replace petroleum ...The basic process for CTL was developed at the beginning of the 20th century and was used by Germany during World War II, when the Allies cut off access to petroleum imports. ...Two different CTL technologies are being considered. The process used by the Nazis and by Sasol is called indirect CTL; it entails gasifying the coal at high pressure and temperature, then using the Fischer-Tropsch process to synthesize a liquid fuel from the syngas. This first process is sometimes also known as "coal gas-to-liquids" or "coal GTL." Shenhua in China is working on a different process, direct CTL, that bypasses the gasification stage.
...Underground Coal Gasification (UCG)... offers an alternative to conventional coal mining for some resources that are otherwise not commercially viable to extract. The basic process consists of drilling one well into the coal for the injection of air or oxygen, and another to bring the resulting gas to surface, and then initiating underground combustion.
...Carbon Capture and Storage (CCS) ...capture the carbon from coal and bury it. ...There are three different types of CCS technologies in development: Post-combustion, pre-combustion, and oxyfuel combustion.
In post-combustion, the CO2 is removed after coal is burned in conventional power plants. The technology is well understood but expensive to deploy.
In pre-combustion, the coal is partially oxidized in a gasifier (see IGCC, above); then the resulting syngas, consisting of carbon monoxide (CO) and hydrogen (H2), is transformed into carbon dioxide (CO2) and H2. The CO2 can be captured relatively easily prior to the combustion of the H2-which can also be used for industrial processes or to fuel transportation.
In Oxy-fuel combustion, coal is burned in oxygen instead of air. ...After CO2 is captured, it must be transported to suitable storage sites. This will almost certainly be accomplished via pipeline. There are already approximately 4,000 miles (5,800 km) of CO2 pipelines in the United States currently being used to carry carbon dioxide to oilfields where it is injected to force oil toward boreholes to maintain production levels when natural pressure wanes. However, the market for CO2 is limited and is destined to shrink in coming decades as depletion gradually forces the oil industry into retirement. ...If and when carbon is captured on a large scale, power producers will have to pay for both CO2 transport and storage. Transport will require the construction of thousands of miles of pipelines, and storage will require drilling and other infrastructure investments. The main forms of permanent storage for captured CO2 currently under discussion include gaseous storage in various deep geological formations [geo-sequestration] (including saline formations and exhausted gas fields), liquid storage in the ocean, and solid storage by reaction of CO2 with metal oxides to produce stable carbonates. ...Each of the coal technologies surveyed here holds promise for addressing one problem or another. None of them is a magic bullet that can overcome long-term production declines of either coal or other fossil fuels due to the depletion of high-grade resources; nor can any of them, even if successfully deployed, truly make coal environmentally benign. All are expensive in economic terms; ...Time will tell which if any of these technologies is deployed on a large scale.

2008 August. Coal and Climate. By Richard Heinberg, MuseLetter #196. Excerpt: ...Since coal is the most significant source of human-generated greenhouse gas emissions, releasing about twice as much carbon dioxide per unit of energy produced as natural gas, the news that there may be much less coal available to be burned than commonly thought should be heartening to climate scientists and environmental activists, and to policy makers and citizens concerned about the fate of the planet. Reduced estimates of future coal supplies should be factored into climate models—which typically assume that there is enough coal available to permit continued expansion of usage well into the next century.
At the same time, because global warming has emerged as the central environmental issue of our era, climate concerns will inevitably impact how much coal we continue to burn and how we burn it—whether these concerns come to be expressed through caps on emissions, carbon taxes, cancellation of orders for new coal-fired power plants, or the promotion of new carbon sequestration technologies. In any case, the coal industry will be—indeed, already is being—forced to change....
...Will efforts to address Climate Change solve the economic problems arising from coal, oil, and gas depletion and increasing scarcity? It is possible in principle, but in reality the stronger likelihood is that energy scarcity will rivet the attention of policy makers and private citizens alike because it is an immediate and unavoidable crisis. The result: as scarcity deepens, support for climate policy may fade even as climate impacts worsen....

2008 June. Coal in the United States. Museletter #194-Richard Heinberg. Excerpt: Because the US has the world's largest coal reserves, it has sometimes been called "the Saudi Arabia of coal." It is the world's second-largest coal producer, after China, but surpasses both the number three and four producer nations (India and Australia) by nearly a factor of three.
...Today coal fuels about 50 percent of US electricity production and provides about a quarter of the country's total energy.
The US currently produces over a billion tons of coal per year, with quantities increasing annually. This is well over double the amount produced in 1960. However, due to a decline in the average amount of energy contained in each ton of coal produced (i.e., declining resource quality), the total amount of energy flowing into the US economy from coal is now falling, having peaked in 1998. This decline in energy content per unit of weight ... can partly be explained by the depletion of anthracite reserves and the nation's increasing reliance on [lower quality] sub-bituminous coal and even lignite, a trend that began in the 1970s. ...Today, Pennsylvania's anthracite is almost gone. Mining companies there are now exploiting seams as thin as 28 inches. West Virginia, the second largest coal-producing state (after Wyoming), where much coal is surface mined in an environmentally ruinous practice known as mountaintop removal, is nearing its maximum production rate and will see declines commence within the next few years, according to a recent USGS report. ...The Illinois basin boasts large reserves of bituminous coal, but production has fallen there since the mid-1990s. Its coal generally has a high sulfur content (3 to 7 percent), which runs afoul of US environmental laws, especially the Clean Air Act of 1990. Prior to this legislation, power plants burning high-sulfur coal released emissions resulting in acid rain that decimated forests throughout much of the nation.
...However coal is mined, the industry must always confront the bottom line: the cost of getting coal out of the ground cannot exceed the market price for produced coal. Thus the current price determines whether marginal coals will be mined profitably, or simply left in the ground. ...During the two-year period from January 2006 to January 2008, prices rose from about $100 a ton to $250 a ton for high-quality metallurgical grades of US coal. Central Appalachian steam coal is currently selling for about $90 a ton, up from $40 two years ago.
...The US has seen a long controversy between coal resource optimists and pessimists-a controversy that is somewhat mirrored in the global coal resource picture. In 1907, Marius R. Campbell, Director of the USGS, headed the first attempt at a scientific survey of US coal, concluding that ultimately recoverable reserves amounted to 3157.2 billion tons. Since production in that year was 570 million tons, simple arithmetic yielded an R/P ratio of 5500/1, which was interpreted as meaning that the nation had a 5,500-year supply. That implied an effectively limitless amount for the practical purposes of economic planning.
...Shortly after World War II, Andrew B. Crichton (a coal engineer and mine operator in Johnstown, Pennsylvania) ....went on to offer his own estimate of national coal reserves as 223 billion tons-a number not that much smaller than the current official estimate. ...National Academy of Sciences [NAS], July 2007, Research and Development to Support National Energy Policy. This book-length report concluded that "there is no question that sufficient minable coal is available to meet the nation's coal needs through 2030," and also that "there is probably sufficient coal to meet the nation's needs for more than 100 years at current production levels" ...Werner Zittel and Jörg Schindler, Energy Watch Group [EWG], March 2007, Coal: Resources and Future Production ... report ... offers several peaking scenarios for US coal. The most optimistic shows a peak in 2070.... They offer two alternative scenarios for future production: one in which only recoverable reserves at existing mines are considered producible (peak in 2015), and the other in which reported estimated recoverable reserves are all producible, but regional production trends are taken into account (peak in 2040). They suggest that "The real profile will be somewhere between these two extremes."
...Previous MuseLetters on global coal supply issues are archived on Global Public Media (www.globalpublicmedia.com) at MuseLetter 193: It's Happening, MuseLetter 190: The Great Coal Rush (And Why It Will Fail), and MuseLetter 179: Burning the Furniture).

2008 May. It's Happening. By Richard Heinberg, MuseLetter #193. Excerpt: ...While oil and gas were formed primarily from enormous quantities of microscopic plants (algae) that fell to the bottoms of prehistoric seas, coal is the altered remains of ancient vegetation that accumulated in swamps and peat bogs (peat currently covers 3 percent of Earth's surface; in previous geologic eras, that percentage was much higher). While oil and gas were formed during two relatively brief periods of intense global warming, roughly 150 and 90 million years ago, coal formation started much earlier and occurred during much longer time spans, with the first primary formation period occurring during the late Carboniferous period (roughly 360 to 290 million years ago), another in the Jurassic-Cretaceous (200 to 65 million years ago), and a third in the Tertiary (65 to 2 million years ago).
All fossil fuels vary in quality. ... At the high end of the coal spectrum is anthracite-a hard, black coal that has more carbon, less moisture, and produces more energy per kilogram than other coals. At the low end are lignite and sub-bituminous coals, which are brown, friable, and have more moisture, less carbon, and a lower energy content. Coal that contains high amounts of mineral impurities (especially sulfur) may be unusable.
The qualities of coal determine its uses. Generally, only anthracite is suitable for making coke for steel production, a process that requires high temperatures; it is therefore referred to as "metallurgical coal" or "coking coal." Since anthracite is much less abundant than other coals, it sells for higher prices; it also therefore tends to be mined preferentially. Other coals are used mainly for electricity generation and are therefore known as "steam coal," but this category includes a wide variety of coal types, from bituminous to lignite. At the lowest end of the spectrum are coals that are barely distinguishable from peat.
...The estimation of coal reserves has evolved through the decades, and now constitutes a sophisticated process entailing the work of thousands of trained and experienced coal geologists around the world....

2008 Apr 8. There's Gas in Those Hills. By CLIFFORD KRAUSS,The New York Times. Fracture drilling workers run machinery on a farm outside of Pittsburgh. Companies are risking big money on rural Pennsylvania, producing billions of dollars' worth of natural gas. Excerpt: HUGHESVILLE, Pa. - At first, Raymond Gregoire did not want to listen to the raspy voice on his answering machine offering him money for rights to drill on his land. They want to ruin my land, he thought. But he called back anyway a week later to hear more. ...Property owners at a seminar in Clarks Summit, Pa., on negotiating with gas lease companies.
By the end of February, he had a contract in hand for $62,000, and he pulled together a group of 75 neighbors who signed $3 million in deals.
"It's a modern-day gold rush in our own backyard," Mr. Gregoire said. ...A layer of rock here called the Marcellus Shale has been known for more than a century to contain gas, but it was generally not seen as economical to extract. Now, improved recovery technology, sharply higher natural gas prices and strong drilling results in a similar shale formation in north Texas are changing the calculus. A result is that a part of the country where energy supplies were long thought to be largely tapped out is suddenly ripe for gas prospecting. ..."Now I can retire," said Robert Deiseroth, a 63-year-old farmer and auctioneer from the town of Hickory, who recently received a $16,000 royalty check from Range Resources that he hopes will be repeated month after month. "This was a godsend for me. If it weren't for this I would have to sell off some of my land to get some money for retirement."....

2008 Mar 19. An Export in Solid Supply. By CLIFFORD KRAUSS, NY Times. Excerpt: ... a vast reorganization of the global coal trade that is making the United States a major exporter for the first time in years- and helping to drive up domestic prices of the one fossil fuel the nation has in abundance. Coal has long been a cheap and plentiful fuel source for utilities and their customers, helping to keep American electric bills relatively low.
But rising worldwide demand is turning American coal into another hot global commodity, with domestic buyers having to compete with buyers from countries like Germany and Japan. Environmental concerns have forced some American utilities to cut back on plans for coal-burning power plants.
..."Watch out, consumer," said David M. Khani, a coal analyst at Friedman, Billings, Ramsey Group. "You're probably going to see accelerating electricity prices in 2009, 2010 and 2011."
...World consumption of coal has increased in recent years by more than 4 percent annually, a major reason that emissions of carbon dioxide are going up, not down. Carbon dioxide is the principal gas implicated in global warming. "Any rise in coal use around the world is bad news for the environment," said Alice McKeown, who works on coal issues for the Sierra Club.
..."As U.S. coal demand is constrained because of increasing environmental regulation, coal production in the United States will increasingly go toward overseas buyers," Chris Ruppel, an energy analyst at Execution, a brokerage and research firm, predicted.
..Kenneth B. Medlock, an energy analyst at Rice University, predicted many more electricity consumers will begin to feel the coal price spike over the next year, particularly in states most dependent on coal, like Kentucky, Illinois and Ohio.
"Their power bill is going to go up, but it also will start to affect the prices of goods they buy at the grocery store," he added.

2008 February. The Great Coal Rush (and Why It Will Fail). By Richard Heinberg, Museletter #190. Excerpt: The world appears poised for a headlong sprint toward greater dependence on coal. ...one crucial question that will shape this next great coal rush: How much is left? The answer from conventional wisdom is, Lots. Coal appears to be the most abundant of the conventional fossil fuels, and everyone agrees that enormous quantities remain to be extracted ...Decades-old estimates assure us that there is 150 years' worth of supply at current rates of production; therefore we should be able to enjoy plenty of coal for several generations to come. However,... this conventional wisdom is in need of substantial correction.
... there is every indication that worldwide petroleum production will begin an inexorable, inevitable decline beginning around 2010. This is the often-discussed phenomenon of Peak Oil ... Many analysts believe that by 2015 oil production will be declining at an annual rate of over two percent per year and prices may be in the multiple hundreds of dollars per barrel.
...China currently obtains nearly 70 percent of its energy from coal and is the world's primary coal consumer, using nearly twice as much as the next country in line (the US). The quantities are staggering: in 2007 alone, China added electrical generating capacity - nearly all of it coal-based - equal to the whole of France's or Britain's entire electricity grid. During 2007, China's installed electricity generating capacity grew 17 percent, reaching over 700 gigawatts, second only to the US's 900+ gigawatts.
It is entirely foreseeable that this enormous, rapid growth in coal consumption should entail an equally enormous environmental cost. ...Coal is the dirtiest of the conventional fossil fuels. Sulfur, mercury, and radioactive elements are released into the air when coal is burned and are difficult to capture at source. During the early phase of the industrial revolution, both the mining and the burning of coal generated legendary amounts of pollution. In cities like London, Chicago, and Pittsburgh, smoke and airborne soot reduced visibility to mere inches on some days.
...One visitor to Pittsburgh during a temperature inversion in 1868 described the city as "hell with the lid taken off," as he peered through a heavy, shifting blanket of smoke that hid everything but the bare flames of the coke furnaces that surrounded the town. During autumn and winter this smoke often mixed with fog to form an oily vapor, first called smog in the frequently afflicted London. In addition to darkening city skies, smoky chimneys deposited a fine layer of soot and sulfuric acid on every surface. "After a few days of dense fogs," one Londoner observed in 1894, "the leaves and blossoms of some plants fall off, the blossoms of others are crimped, [and] others turn black." In addition to harming flowers, trees, and food crops, air pollution disfigured and eroded stone and iron monuments, buildings, and bridges. Of greatest concern to many contemporaries, however, was the effect that smoke had on human health. Respiratory diseases, especially tuberculosis, bronchitis, pneumonia, and asthma, were serious public health problems in late-nineteenth-century Britain and the United States....
