Is this coal clean?
27 Dec 08 | EnvironmentThe dam around a retaining pond a TVA’s coal fired Kingston power plant burst and an estimated billion (B) gallons of coal ash and sludge flowed out covering more than 300 acres of adjacent land. Several neighbors had to be evacuated from there homes as fears of water and airborne contamination spread.
There is no technology that can get rid of coal ash, also known as fly ash, which is a byproduct of coal combustion. The TVA insists that fly ash is non toxic, however the EPA is of a different mind, from the New York Times:
A draft report last year by the federal Environmental Protection Agency found that fly ash, a byproduct of the burning of coal to produce electricity, does contain significant amounts of carcinogens and retains the heavy metal present in coal in far higher concentrations. The report found that the concentrations of arsenic to which people might be exposed through drinking water contaminated by fly ash could increase cancer risks several hundredfold.
The post industrial revolution development scheme tends to use the strategy of building super regulated subdivisions miles away from power plants or other industrial activities. After all, who want there back yards to look like this:
This merely pushes the problem further away, which allows the problem to grow bigger and bigger and bigger until it takes over and ruins the entire area. Our coal use should be getting smaller with an eye toward phasing it out all together. Soon.

Greenwashing Coal
16 Oct 08 | Commentary, EnvironmentWe have a serious energy problem our hands. I fear it will get worse before it gets better. We may need to build more coal fired electric plants to meet future demands for energy, especially if we migrate to electric vehicles. Hey, that electricity has to come from somewhere. Unfortunately, solar electric, either by harnessing heat to make steam or photovoltaics, is still a long way from being able to fill that demand.
To bridge that gap, we have but two choices, nuclear or coal. I am not sure what the lesser of those two evils are. That being said, please don’t tell me that coal is clean.
Coal is anything but clean; from its extraction to its final use, coal is dirty. From the mountain top removal sites in West Virgina, where environmental damage is almost indescribable, to the electric generation station billowing out not just CO2, but Sulfur Dioxide, Nitric oxides, Mercury, Uranium, Cesium and other heavy metals, the damage to the environment is nearly incalculable.
Ask the residents of the West Virgina coal region whether they are prospering along with the companies that mine the coal. Ask anyone living down wind from a coal fired power plant how they feel on a day to day basis. Look at the environmental record of both the coal producers and the power producers. Is this the kind of behavior we want to reward?
Somewhere along the line, somebody decided that all business was about greed. Being the good consumers that we are, we happy citizens followed right along and made our personal lives about money. After all, coal is cheap, the energy produced by coal is cheap, therefore it must be good.
There are, indeed, new technologies that greatly reduce the emissions of coal fired electrical power plants. These include things like scrubbers to remove nitric and sulfur compounds, CO2 capture and sequestration. These newer technologies are not normally retrofitted to older facilities. The average life span of a coal fired power plant is anywhere from 30 to 50 years. The plants that were previously built will continue to spew pollutants for years to come.
Not everything is about money. There are quality of life issues as well. Even if you live hundreds of miles away from any coal mines or power plants, eventually, the environmental damage will be so great that you will be effected.
