Abandoned Mines Could Be Used for Other Purposes: Geothermal Energy

Coal power supplies most of the electricity that we use here in America. It’s been that way for a long time. Because of coal’s popularity as a source of power, mines, both active and abandoned, lay scattered across the nation. And now, with coal’s popularity waning, the number of abandoned mines could increase. Since 2001 alone, 100 coal-fired plants have taken their turn in front of the firing squad.

And it doesn’t seem as though it’s over. 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.

Two engineers from the University of Oviedo have an idea, though. In their research, which is being published in the journal Renewable Energy, Rafael Rodríguez and his colleague María Belarmina Díaz claim that mine shafts on the point of being closed down could be used to provide geothermal energy to local towns.

100 Down: Sierra Club Celebrates the Abandonment of Another Coal-Fired Power Plant

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.

Court Halts Construction of Coal-Fired Power Plant in Georgia

A Superior Court Judge in Fulton County, Georgia has ruled that construction of Dynegy’s Longleaf plant be halted until it is assured the plant will limit the amount of carbon dioxide it releases.

The original permit would have allowed the plant to emit 9 million tons of carbon dioxide annually, something the court said was unreasonable.

The court cited the Supreme Court’s 2007 ruling recognizing that carbon dioxide is a pollutant under the federal Clean Air Act. It’s the first time any court has applied the ruling to an industrial source.

Commenting on the ruling, Bruce Nilles, director of the Sierra Club’s National Coal Campaign said:

“Coal-fired power plants emit more than 30% of our nation’s global warming pollution. Thanks to this decision, coal plants across the country will be forced to live up to their clean coal rhetoric.”
