If the trend of extinguishing coal-fired plants continues, more and more mines will be shut down, not to mention mines that simply up and quit. But what is to be done with the abandoned mines? It isn’t as though we can just dispose of them at some hi-tech facility. These mines will become useless scars.
As a pollutant polycyclic aromatic hydrocarbons (or PAH’s as we call them in the business), are of concern because they have been identified as carcinogenic, mutagenic, and teratogenic (not good things if you were wondering). PAHs are created as a byproduct of the burning of coal, oil, and fossil fuels. Often they are of concern in urban areas where there is a higher carbon footprint, and it forms that nice cloud of yellow smoke you see floating over some of your major cities.
Now, new research out of Columbia University is showing that exposure to PAHs, can reduce neonate’s intelligence. The study performed in New York city where PAHs are in no short demand, showed IQ scores that were 4.31 and 4.67 points lower, respectively than those of less exposed children.
The discovery of a tiny bowl-shaped molecule which collects carbon dioxide right out of the air has beckoned some creative solutions to global warming.
By genetically engineering microbes to manufacture the handy molecule, scientists hope to make it useful as an industrial absorbent for CO2 capture. That could help clean up smokestacks from dirty coal-fired power plants, but it’s also possible that the molecules could be used for pulling carbon dioxide right out of the ambient air.

In 2001, energy companies across the United States were busy drawing up plans for about 150 new coal-fired power plants. That year, Sierra Club launched its Beyond Coal campaign.
Today, the campaign celebrated its 100th defeat of a proposed coal plant.
“Coal mining is literally blowing the tops of mountains in Appalachia, coal burning is literally heating up our planet, spewing mercury across our landscape, and exposure to coal ash is wreaking havoc on streams and rivers across this country. So in every phase of the lifecycle, coal is filthy business,” Sierra Club campaign director Bruce Nilles said in announcing the milestone.
“We have persuaded the developers, the investors and the decision makers that we can do better than building dirty coal-fired power plants.”
I can see clearly now, the smoke is gone. Or prevented. Thanks to the Sierra Club, who celebrated a landmark in the fight against coal today. Thanks to advocacy in favor of ending coal, Intermountain Power decided to pull the plug on a coal plant in Delta, Utah, making the 100th plant to be either abandoned or prevented since the beginning of the 2001 coal rush.
The Delta plant “would have burdened Utah with more coal-burning pollution,” said Wayne Hoskinson, chairman of the Utah Chapter of the Sierra Club. “This opens the door for additional renewable projects, like the Milford wind development, allowing the state to still be an exporter of energy without the cost of worsened air quality and more mercury pollution.” It is exactly this shift from coal to renewables that the Sierra Club has been advocating since it began its Beyond Coal Campaign.
The abandonment of the Delta plant comes in the wake of Los Angeles Mayor Antonio Villaraigosa’s announcement last week that Los Angeles would be coal free by 2020 and is reason to celebrate. “Stopping one hundred coal plants is a huge milestone in our fight to end global warming,” said Bruce Nilles, Director of the Sierra Club’s Beyond Coal Campaign.
The Brindisi facility is Italy’s biggest coal-fired power station and the country’s largest single C02 polluter. The Greenpeace sabotage operation will entail blocking the coal conveyor belts and preventing coal from going into the plant.
Coming in at second place in the world in energy consumption - second only to the United States - the People’s Republic of China (PRC), the world’s most populated nation, is looking for ways to shift to renewable energy. This desire to increase renewable energy sources and cut greenhouse gases has led the PRC to promote private investments in renewables.
Divisions within the EU have led to an agreement which ignores Carbon Dioxide as a pollutant and allows member nations to delay implementation of stricter emission standards.
NASA’s Dr. James Hansen joined in an act of civil disobedience against mountaintop removal mining by attempting to trespass on the property of Massey Energy near Coal River Mountain in West Virginia, and was arrested along with other protesters including Darryl Hannah and former US Representative Ken Hechler (D-WV).
