I can't blame you for that Charlie. I did a little research and this what I came up with. 23 g of coal burned produces 44g of Co2 which is a factor of 1.91 to 1. Pattison claims tonnes shipped in 25 yrs is 675,000,000 tons. That multiplied by 1.91 = 1,289,250,000 tons of Co2. A little blip so they say. Clean Co2 he says.
The US alone produces 35% of the worlds coal 2,362,500,000 tons. More than half of electric power produced in the states is produced from burning coal. 3.8 tons per person per year. Co2 from coal produced per year = 4,512,375,000 tons yr. Coal burned per person to produce power = 14,516 tons of Co2 per yr.
The state of Texas consumes 100,000,000 tons per yr. Ontario canada buys coal from the US to produce electricity, do the numbers on Canada you will find just as bad or worse numbers, go to Europe and you will find the same ****. To me I can't fathom why the blame seems to lie on the Tarsands back while coal is happily smoking out stacks that are getting higher and higher. Tarsands is not the only culprit in this equation, albeit they are trying to get their foot in the door a big way.
My point is while big attention is focused on tarsands the just as big criminal plays on.
I have accrued the information through Google.
When the coal burns, it gives off sulfur dioxide, nitrogen oxide and carbon dioxide, among other gases. The sulfur particulates are partly removed with scrubbers or filters. Scrubbers use a wet limestone slurry to absorb sulfur as it passes though. Filters are large cloth bags that catch particles as they go through the cloth. Scrubbers are more common, and can reduce sulfur emissions by up to 90 percent, when working properly. Still, smaller particulates are less likely to be absorbed by the limestone, and can pass out the smokestack into the air.
Another type of coal plant uses "fluidized bed combustion" instead of a standard furnace. A fluidized bed is made up of small particles of ash, limestone and other non-flammable materials, which are partially suspended in an upward flow of hot air. Powderized coal and limestone are blown into the bed at high temperature. They burn in the bed, and the limestone binds with sulfur released from the coal. The heat then boils water in pipes which completes the Rankine Cycle. The advantage of fluidized bed combustion is that sulfur emissions are lower than in standard coal plants. The down side is that the plants are more complex and require more maintenance.
Sulfur control methods like scrubbers, fluidized bed combustors and switching to low-sulfur coal reduced sulfur emissions by 33 percent between 1975 and 1990, even while coal use increased by 50 percent. Nitrogen oxide emissions have stayed pretty much the same over this period. Carbon dioxide emissions, which can't be removed from the plant's exhaust, have risen with coal use however.
Coal provides just over half of the electricity produced in the US.
A Case Study: The Side Effects of a Coal Plant
A 500 megawatt coal plant produces 3.5 billion kilowatt-hours per year, enough to power a city of about 140,000 people. It burns 1,430,000 tons of coal, uses 2.2 billion gallons of water and 146,000 tons of limestone.
It also puts out, each year:
10,000 tons of sulfur dioxide. Sulfur dioxide (SOx) is the main cause of acid rain, which damages forests, lakes and buildings.
10,200 tons of nitrogen oxide. Nitrogen oxide (NOx) is a major cause of smog, and also a cause of acid rain.
3.7 million tons of carbon dioxide. Carbon dioxide (CO2) is the main greenhouse gas, and is the leading cause of global warming. There are no regulations limiting carbon dioxide emissions in the U.S.
500 tons of small particles. Small particulates are a health hazard, causing lung damage. Particulates smaller than 10 microns are not regulated, but may be soon.
220 tons of hydrocarbons. Fossil fuels are made of hydrocarbons; when they don't burn completely, they are released into the air. They are a cause of smog.
720 tons of carbon monoxide. Carbon monoxide (CO) is a poisonous gas and contributor to global warming.
125,000 tons of ash and 193,000 tons of sludge from the smokestack scrubber. A scrubber uses powdered limestone and water to remove pollution from the plant's exhaust. Instead of going into the air, the pollution goes into a landfill or into products like concrete and drywall. This ash and sludge consists of coal ash, limestone, and many pollutants, such as toxic metals like lead and mercury.
225 pounds of arsenic, 114 pounds of lead, 4 pounds of cadmium, and many other toxic heavy metals. Mercury emissions from coal plants are suspected of contaminating lakes and rivers in northern and northeast states and Canada. In Wisconsin alone, more than 200 lakes and rivers are contaminated with mercury. Health officials warn against eating fish caught in these waters, since mercury can cause birth defects, brain damage and other ailments. Acid rain also causes mercury poisoning by leaching mercury from rocks and making it available in a form that can be taken up by organisms.
Trace elements of uranium. All but 16 of the 92 naturally occurring elements have been detected in coal, mostly as trace elements below 0.1 percent (1,000 parts per million, or ppm). A study by DOE's Oak Ridge National Lab found that radioactive emissions from coal combustion are greater than those from nuclear power production.
The 2.2 billion gallons of water it uses for cooling is raised 16 degrees F on average before being discharged into a lake or river. By warming the water year-round it changes the habitat of that body of water.
Coal mining creates tons of hazardous and acidic waste which can contaminate ground water. Strip mining also destroys habitat and can affect water tables. Underground mining is a hazard to water quality and to coal miners. In the mid-1970s, the fatality rate for underground miners was 0.4 per million tons of coal -- one miner would be killed every two years to supply our 500 MW plant. The disabling injury rate was 38 people per million tons -- 106 miners would be disabled every two years to supply this plant. Since coal mining is much more automated now, there are many fewer coal miners, and thus many fewer deaths and injuries.
Transportation of coal is typically by rail and barge; much coal now comes from the coal basins of Wyoming and the West. Injuries from coal transportation (such as at train crossing accidents) are estimated to cause 450 deaths and 6800 injuries per year. Transporting enough coal to supply just this one 500 MW plant requires 14,300 train cars. That's 40 cars of coal per day.
Jim Patterson might disagree with you, as his company refers to coal as:
Clean Energy Solutions
Energy (or thermal) coal is the world's most abundant and cheapest source of fuel for power generation. It holds the best hope of reducing world poverty by producing inexpensive and safe electricity. As the world moves to a more environmentally friendly and reliable power source, coal remains the number one energy provider.
Coking (or metallurgical) coal is the principal ingredient in the production of steel through the blast furnace method,and makes up the majority of the coal handled by Westshore. Westshore loads ships bound for the major steel-making countries around the globe. Over the last five years, China has continued to double its consumption of metallurgical coal for its steel making mills annually,producing a record 700 million tonnes of steel in 2011.
Overall in 2011, Westshore moved a record 27.3 million tonnes of coal,up from its previous record of 24.7 million tonnes in 2010. This improved performance has come through expansive equipment upgrades over the past five years. Our first three-year, $47 million project was completed in 2010 and increased Westshore's nominal annual coal throughput capacity from 24 to 29 million tonnes. This phase added a replacement dumper barrel in the coal unloading station, as well as new conveyors and ancillary equipment and a fourth new highly efficient. state-of-the-art stacker-reclaimer.
A second, $53 million project is underway to replace an old single rotary dumper and add a second twin set dumper,available for train unloading. To speed the unloading process.
Westshore is also adding three coal car positioners to the dumper station,including two exit positioners for the first time, which will speed up the dumping cycle. The positioners move the train through the dumper under Westshore's control. The two oldest stackerreclaimers on site have been upgraded, and four of the seven conveyor transfer chutes are being redesigned and replaced. This second major capital project is expected to be completed late in 2012 and will take Westshore's capacity from 29 to an estimated 33 million tonnes a year.
Coal from the United States Powder River Basin is being exported through Westshore at record levels, exceeding 8 million tonnes in 2011.
Westshore's future has never been brighter, with the most bullish coal market in the past 30 years. With this in mind, Westshore has signed long-term contracts with its major customers - Teck Coal and Grande Cache Coal in Canada, as well as Signal Peak and Cloud Peak in the United States Powder River Basin in Montana-to ensure security of supply well into the future.Evolving coal mine developments in Alberta and northeastern British Columbia are expected to add demand for increased ship loading capabilities.
Westshore has an experienced and reliable workforce of over 200 full-time employees who are engaged with our plans to modernize our plant and site to take advantage of what promises to be a very bright future.
