Coal is NOT the Solution

Steve Heckeroth at Mother Earth News describes why coal is not a good source of energy. Excerpts below.

Coal is burned mainly to produce electricity, and coal-fired power plants produce more than half the electricity used in the United States. But burning coal has serious drawbacks. One is that it releases carbon dioxide, which contributes to global warming. It also releases heavy metals, such as mercury and sulfur. These toxins that were locked in the Earth’s crust over billions of years are suddenly spewed into the atmosphere and thus degrade our air, water and soil. The exhaust from burning coal contains more pollutants and global warming emissions per unit of energy produced than any other fossil fuel. In addition, the methods used to mine coal are destructive to the land and dangerous for the miners.

Now consider that coal is enormously inefficient from a total energy perspective. It took billions of years of solar energy to form the coal we have today. And while coal is the most abundant fossil resource, the total amount of energy produced by burning all the coal on the planet would only be equivalent to the solar energy that strikes the Earth every six days.
