The Cost of Coal Power

Coal Miners - Coal Mining in India
About three-quarters of the anthropogenic emissions of carbon dioxide to the atmosphere during the past 20 years have been due to fossil-fuel burning. Activities consuming fossil fuels include power generation, industrial/manufacturing processes, transport. The rest of carbon dioxide emissions are predominantly due to land-use change, especially deforestation.

The main drawback of fossil fuels is pollution. Burning any fossil fuel mainly produces carbon dioxide, which contributes to the “greenhouse effect”, warming the Earth. It produces more carbon dioxide than burning oil or gas. It also produces sulphur dioxide, a gas that contributes to acid rain. We can reduce this before releasing the waste gases into the atmosphere. It is a leading cause of smog, global warming, and air toxics.

Coal is Nasty

Coal is particularly nasty. The attraction to coal is powerful and obvious. According to the World Coal Association, it has been estimated that there are over 847 billion tonnes of proven coal reserves worldwide. This means that there is enough coal to last us around 118 years at current rates of production. In contrast, proven oil and gas reserves are equivalent to around 46 and 59 years at current production levels. Unverified sources have claimed Pakistan has one of the largest coal (lignite) deposits in the world, consisting of 184,123 billion tons, which can produce 1,000,000 MW of electricity for next three hundred years.
World Coal Reserves


Microscopic particles like sulphates and carbon released from coal-burning power plants and automobiles can reflect sunlight back into space, producing a cooling effect. This can in turn influence global wind circulation patterns that underlie the monsoon system.

One 500 MW power plant generates about 3 million tons of carbon dioxide every year. Other toxic byproducts include fine particulate matter, heavy metals like mercury, lead, chromium and nickel, trace elements such as arsenic and selenium, and various organics like dichloroethane, benzene, carbon tetrachloride, chloroform, and trichloroethylene.

Oxides of nitrogen and sulfur are common pollutants from coal, and are found at higher levels in anthracite than in bituminous coal.

Coal mining produces methane, a potent greenhouse gas. Methane is the naturally occurring product of the decay of organic matter as coal deposits are formed with increasing depths of burial, rising temperatures, and rising pressures over geological time. A portion of the methane produced is absorbed by the coal and later released from the coal seam and surrounding disturbed strata during the mining process.

According to the Intergovernmental Panel on Climate Change, methane has a global warming potential 21 times greater than that of carbon dioxide on a 100 year time line. While burning coal in power plants is most harmful to air quality, due to the emission of dangerous gases, the process of mining can release pockets of hazardous gases.

Air Quality Isn’t Getting Any Better

The World Health Organization estimates more than 2 million people die every year from breathing in tiny particles present in indoor and outdoor air pollution. PM10 particles, which are particles of 10 micrometers or less, can penetrate into the lungs and may enter the bloodstream, can cause heart disease, lung cancer, asthma, and acute lower respiratory infections.

The WHO air quality guidelines for PM10 is 20 micrograms per cubic meter (µg/m3) as an annual average, but the data released today shows that average PM10 in some cities has reached up to 300 µg/m3.

The Ozone Layer, which is so essential for life on earth, is unfortunately being depleted due to different kinds of pollutions. The global community, especially the developing countries are now facing the challenge of the elimination of Hydro-chlorofluorocarbons (HCFC) in the foam and refrigeration industry. It is a second kind of Ozone Depleting Chemical Substance which has low Ozone Depleting Potential (ODP), yet possesses high Global Warming Potential (GWP).

The Cost of Coal Power

The true cost of coal power is evident in the known health consequences of this toxic brew of air and water pollution. They contribution to health conditions are many, and include nervous system problems in infants and children, asthma, chronic bronchitis, lung cancer, a suite of cardiovascular problems and kidney disease. The environmental impacts are well documented, and are not pretty either.

  • 3,700,000 tons of carbon dioxide (CO2), the primary human cause of global warming–as much carbon dioxide as cutting down 161 million trees.
  • 10,000 tons of sulphur dioxide (SO2), which causes acid rain that damages forests, lakes, and buildings, and forms small airborne particles that can penetrate deep into lungs.
  • 500 tons of small airborne particles, which can cause chronic bronchitis, aggravated asthma, and premature death, as well as haze obstructing visibility.
  • 10,200 tons of nitrogen oxide (NOx), as much as would be emitted by half a million late-model cars. NOx leads to formation of ozone (smog) which inflames the lungs, burning through lung tissue making people more susceptible to respiratory illness.
  • 720 tons of carbon monoxide (CO), which causes headaches and place additional stress on people with heart disease.
  • 220 tons of hydrocarbons, volatile organic compounds (VOC), which form ozone.
  • 170 pounds of mercury, where just 1/70th of a teaspoon deposited on a 25-acre lake can make the fish unsafe to eat.
  • 225 pounds of arsenic, which will cause cancer in one out of 100 people who drink water containing 50 parts per billion.
  • 114 pounds of lead, 4 pounds of cadmium, other toxic heavy metals and trace amount of uranium.

Pollution from coal mining may have a negative impact on public health in mining communities, according to data analyzed in a West Virginia University research study. Miners in coal companies are on higher risk rather than people living away from mining areas. According to Hendryx, main researcher, the data show that people in coal mining communities:

  • Have a 70 percent increased risk for developing kidney disease.
  • Have a 64 percent increased risk for developing chronic obstructive pulmonary disease (COPD) such as emphysema.
  • Are 30 percent more likely to report high blood pressure (hypertension).

October is Children’s Health Month, and it’s a good time to focus our attention on cleaning up hazards that affect kids as they grow and develop.

Update on NASA’s Hidden Fuel Depot Studies

NASA Is Considering Fuel Depots in the Skies, NY Times

"At a Congressional hearing in July, Representative Dana Rohrabacher, Republican of California, asked Maj. Gen. Charles F. Bolden Jr., the NASA administrator, about the possibility of depots as an alternative to the Space Launch System. General Bolden said that he did not know details about any propellant depot study, but that his agency had looked at alternatives to building a heavy-lift. "It turned out that was not as economical, nor as reliable," he said. Although General Bolden promised to provide the information, Mr. Rohrabacher said he had obtained the study about propellant depots only through unofficial channels. "I'm shocked that the leadership in NASA would try to keep a report as significant as this away from decision makers of the legislative branch," Mr. Rohrabacher said, adding that the study gave him "the ammunition to make a case" to revisit NASA's plans for human spaceflight."

WHAT a day for Grey Phalaropes on the Farnes

'Neil the Seal' sticking his tongue out (Ciaran Hatsell)

That's better, Neil doing well (Ciaran Hatsell)

The boys enjoying the seawatching and Grey Phalarope spectacular

Saturday 22nd October comments: It's been an enthralling day on the islands as we've seen it all. The day began with a southerly breeze and a rush of excitement as resident warden Ciaran broke the silence with the shout of "TWO GREY PHALAROPES SITTING ON THE SEA!" Moments later I joined him to enjoy this stunning sight, as the birds were feeding just 20 metres offshore from Brownsman, not a bad way to start the day!

However as we watched, the two took flight and decided to track north which wasn't such a good idea as one of our resident Merlin's decided to try its' luck. Astonishingly the Merlin pursued its quarry over the sea and in a bold attempt to escape, the Phalarope gained height and when we lost the pair, both were specs way above Brownsman. The outcome of the chase was not known but minutes later, we did see a Merlin return empty taloned. That was one lucky Phalarope.

Seawatching throughout the day was very productive as we recorded all four Skua species, a juvenile Sabine's Gull, a very late Arctic Tern, and two lovely Little Auks. It was all go on the islands. The excitement didn't finish there as mid-afternoon a total of six (YES SIX) Grey Phalaropes were seen on the sea together, all in the same field of view. The birds were feeding together and this represents a new Farnes record count and an incredible sight in British waters. Six of the best!

On the Seal front, Brownsman now boasts six pups (each day brings more and more) and our first, now named 'Neil the Seal' is doing well, being cared for by its attentive mother. During the process of checking the Seals, we came across a pup being born, a truly amazing sight rarely seen on the islands (I've only ever seen this on a handful of occassions in eleven years). What a day, roll on tomorrow.

Highlights: Grey Heron, Teal 27, Wigeon 6, Knot 2, GREY PHALAROPE 6 (SIX) on the sea together (Farnes record), Little Gull adult north, Great Skua 27N, Arctic Skua 6M, Long-tailed Skua juvenile north at 10:10, Pomarine Skua juvenile north at 15:13, Sabine's Gull juvenile north, Arctic Tern adult north, Little Auk 2N, Puffin, 3, Fieldfare 24, Brambling and Snow Bunting.

Meanwhile down on the Bayou, it’s Jindal in a landslide!

And on the same day LSU beats Auburn 45 to 10!

From Cliff Thies:

Down in Louisiana, Governor Bobby Jindal was re-elected in a landslide on Saturday, pulling 66 percent of the as of yet incomplete vote.

Republicans swept all seven statewide offices and both chambers of the state legislature. And as if an omen from a higher authority for his next four years in office, on the very same day, Louisiana State beat Auburn 45 to 10.

From the AP via USAToday "La. Gov. Bobby Jindal wins re-election":

Bobby Jindal on Saturday easily coasted to a second term, winning in a landslide election... The 40-year-old Republican overwhelmed nine competitors in the open primary, where a candidate wins the race outright if he or she receives more than 50 percent of the vote. With 99 percent of precincts reporting, Jindal had received about 66 percent of the total vote.

His closest competitor, Tara Hollis, a Democrat from north Louisiana, garnered nearly 18 percent of the total vote. All of the other candidates were in single digits.

A "virtual collapse" of the Democrat Party in Louisiana

Continuing from USAToday piece:

"I will use every day, every hour of these next four years to make Louisiana the very best that we can be. I don't believe in resting on our past accomplishments. I don't believe in taking time off," Jindal told a packed hotel ballroom of supporters in Baton Rouge.

His win comes amid the virtual collapse of the Democratic Party's clout in the state. In the current term, Republicans have gained control of all seven statewide elected posts and both chambers of the legislature...

his brand of conservatism and refusal to raise taxes has resonated outside the state.

Note from the Editor - We here at LR supported Jindal way back in '07 when nobody knew who he was. We couldn't resisit adding this golden oldie video from 2008 - NoBama Merci Beaucoup - to celebrate Bobby's big win. Let it be a theme song for GOP Victory 2012. Enjoy!

Two Republicans giving it a shot in heavily Democrat city in upstate NY

Rainbow flag-waving "social libertarian" Republicans for Rochester

From Rochester Democrat-Chronicle "Yes Virginia, there are still Republicans in the city" Oct. 22:

Rich Tyson says he has spent a fair amount of time trying to convince city voters that he is not Dick Cheney.

Such is the life of a Republican running for office in Rochester, where registered Democrats outnumber Republicans five to one and being likened to Cheney is, put mildly, not a compliment.

Andreas Rau is the other Republican City Council candidate in a city where a Republican hasn't held office since 1988. The two have been going door-to-door in their districts trying to convince voters that 2011 is their year.

Tyson is a member of the Roc City Skate Park board and describes himself as a fiscal conservative and a social libertarian. Rau flies a rainbow flag in his yard, along with six American flags.

Content Streaming = Living Like Kings

As a video gaming and movie addict, I’ve always followed the latest trends and news in these two areas. Because there always seems to be some “breaking news” every day due to technology advancing so rapidly, sometimes it’s tough to keep up.

In gaming, I remember it all started for me back when my parents decided to buy me the first Nintendo console. Pointing that light sensor gun at unsuspecting ducks and watching them fall was all the rage … It marked a big step in the evolution of home gaming. What initially seemed like a good investment to keep me out of trouble soon turned into a headache for my parents. I frequently begged for more games, and they were not cheap. Look at how much new video games cost these days, and you’ll see that not much has changed in that regard. The fire to play all the latest games was never extinguished, so a chunk of my income was always earmarked for the next amazing game I needed.

As for movies, I also found myself collecting as many as possible to rewatch whenever I choose. While each individual movie didn’t cost as much as a video game, the aggregate costs definitely built up over time. My family and friends warned me that my “extravagant lifestyle” is reserved for the rich and would only lead me to financial ruin.

Fast forward to today, and I can say that I’ve learned a lot and found ways to sustainably feed my addiction without driving myself to financial ruin. How is it possible that I am able to live like a king without breaking the bank? It’s all thanks to content streaming, made possible by the Internet. I no longer have to buy every single game to have the ability to play whenever I feel like it with services like OnLive that actually streams numerous games to my TV (and a few other supported devices). Beyond the fact that I save money by not buying the game, I don’t even need the latest computer hardware to play the more graphics-intensive games like Crysis:

Crysis

You might not be familiar with OnLive just yet, but most people know about content steaming from companies like Netflix and Amazon. You can stream countless movies to your devices to watch movies on demand for a monthly fee or on a per-movie basis. With these services readily available, it’s possible for just about anyone have the “kid in the candy store” experience of pulling up essentially any content whenever we want to watch or play.

If either form of entertainment appeals to you, you can agree that our quality of life has improved over time significantly. The streaming services provided by companies like Netflix and OnLive have really taken advantage of the technological capabilities offered by high speed Internet, which also reminds us of the significance of web hosting. To offer customers complete satisfaction, deciding which web hosting company to go with for a business is often a very difficult decision, especially since there are so many out there. It would make complete business sense to find an extremely reliable company to ensure the success of such services and having worked in the industry, and I can assure you with much pride that SoftLayer certainly shines in this area.

As an employee, I see how we’re building our network to provide the best experience around the world, and if there’s ever a problem, we treat all outages with extreme urgency. Customers get better turnaround times, and they can provide better service for their customers. If some content streaming were to become unavailable, it wouldn’t be long before it became available again.

It’s pretty safe to say that the Internet has spoiled me … Now all I need is a crown.
