Environmental and Safety Hazards Associated with Various Energy Sources

Posted by Josh on Monday, 8 February, 2010

In the wake of yesterday’s explosion at a natural gas plant in Connecticut, Caroline Howe at Its Getting Hot in Here makes a good point:

Fossil fuels are not safe. They are not safe for our planet, they are not safe for our communities, and they are not safe for the workers inside of their power plants. This is not the first power plant explosion, this will not be the last. It is time for America to commit to a clean and safe energy economy – where our friends and neighbors can work in green jobs that give good wages and safe working environments. My heart and prayers are with the workers at the Kleen Energy Plant and with their families — and with the future of our nation to not face such a tragedy again.

Greenhouse gas emissions aside, here are a few recent environmental problems and public health concerns associated with generating electricity from coal, nuclear and natural gas:

  • Yesterday — Middletown Power Plant Explosion Caused By Gas Leak, Officials Say: “Early reports were that a natural gas leak could have caused a devastating explosion Sunday morning that killed two and injured as many as a dozen more at a power plant being built south of the city on the Connecticut River.”
  • Last week — Radiation Levels Spike Near Vt. Nuke Plant; Leak Source Not Yet Found: “Levels of radioactive tritium mushroomed Thursday in a new monitoring well at the Vermont Yankee nuclear reactor, an indication the leak was coming from water that runs through the reactor itself, according to the Department of Health.  These are very high concentrations,” said William Irwin, radiological health chief for the Department of Health, who was at the reactor Thursday. “We’re not dealing with a minor system. It’s an important source that needs to be quickly found.”
  • Last week — The EPA released “engineering assessments of 40 more coal ash impoundments showing they have the ‘high’ or ’significant’ potential to cause loss of human life, environmental damage, or damage to infrastructure.”
  • 9 months ago — 8 Firefighters, 1 Gas Employee Burned In Natural Gas Explosion: “Eight firefighters and a gas company worker were injured in a natural gas explosion at a strip mall in Forestville, Maryland on Thursday afternoon. Despite being caught in the violent explosion, only two of the injured remain hospitalized.”
  • 13 months ago — TVA spilled 5.4 million cubic yards of toxic coal ash in Eastern Tennessee. “A test of river water near the spill showed elevated levels of lead and thallium, which can cause birth defects and nervous and reproductive system disorders”
  • Natural gas drilling has contaminated the water in several states.
  • Coal mining releases methane, carbon monoxide, soot, copper lead and mercury at levels known to pose risks to human health.

And here are some recent environmental problems and public health concerns associated with generating electricity from solar, wind and geothermal:

  • Actually, there are no environmental problems or public health concerns associated with generating electricity from wind, solar and geothermal sources.

Just something to keep in mind when you hear people talk about ‘cleaner burning natural gas,’ ‘clean coal,’ and ’safe nuclear power.’

Update — Senator Lautenberg has questions:

Sen. Frank Lautenberg (D-N.J.) said Monday that a fatal explosion at an unfinished natural gas-fired power plant in Connecticut over the weekend underscores safety concerns about a proposed natural gas pipeline in New Jersey.

An explosion Sunday at the Kleen Energy Systems plant in Middletown, Connecticut killed at least five workers.

“This tragic incident reminds us that natural gas, while cleaner burning than other fossil fuels, comes with safety risks. The explosion raises a red flag about the construction of a natural gas line that would run through New Jersey primarily for the benefit of New York,” Lautenberg said in a prepared statement.


America’s Power Plants Are Mostly Really Old and Really Dirty

ClimateWire:

Three power plants owned by Southern Co. top the list of U.S. coal-fired sources of heat-trapping carbon dioxide emissions, according to rankings released today by an environmental group.

The Atlanta-based utility’s Plant Scherer in Georgia topped the list, emitting about 27 million tons of CO2 annually in 2007, according to the report (pdf) released today by Environment America. The James H. Miller Jr. Plant in Alabama was the No. 2 emitter, followed by Plant Bowen in Georgia.

27 million tons of CO2 in one year. As the chart on page 18 points out, that is the equivalent of about 4.8 million cars. What is that I keep hearing about clean coal?

The report is largely about the fact that most of the power plants in the United States are really really old, and thus, really really dirty. Consider this chart:

Here is the report:
