At Issue in the 21st Century: Coal-Fired Power Plants
As we bump along into a new year, perhaps it’s time to ask ourselves: What do the world’s scientists tell us about our course vis-à-vis sustainability? Well, a lot of things, really. For example, our oceans are over-fished and filled with mercury, and the natural mineral content of our farmland is so depleted that the chemical fertilizers and poisons we’ve chosen to mitigate the damage is crippling our environment, while leaving us with food increasingly lacking in nutritional content.
This could be the beginning of a very long list, so I’ll skip ahead to the granddaddy of them all: our society’s burning coal for energy. In brief, the developing world expects to enable its huge and ever-growing populations to enjoy the fruits of cheap and abundant energy in the 21st Century, the same way the developed world did in the 19th and 20th Centuries. There’s a catch, though, as there often is. If we pull all that carbon out of the ground and release it into the atmosphere, we’ll cause catastrophic climate change, not to mention other forms of ecologic collapse of monumental proportion.
Here’s a great article that speaks to where we are in terms of the construction and operation of coal-fired power plants. Note that in five years, the amount of coal burned around the globe every year will increase by an additional 1.2 billion metric tons — an amount roughly equivalent to the current annual coal consumption of the U.S. and Russia combined.
