Hal Quinn, president of the National
Mining Association, says coal in 2016 will again be the world’s favorite carbon
fuel, pushing out petroleum as the world's largest source of energy.
This may seem especially surprising at a
time when the use of coal in the United States is in decline, edged out by
cheap natural gas and increasingly strict regulations from the Environmental
Protection Agency. Yet a rising tonnage of coal is being used for electric
generation worldwide.
The Third World is hungry for coal, as it
increases electricity production. In the developed world, nuclear setbacks --
most notably the aftereffects of the Fukushima-Daiichi nuclear power plant
accident, when a tsunami wave knocked out six reactors -- have helped boost the
commitment to coal. The accident has forced the Japanese to burn more coal and
the Germans to begin phasing out their nuclear power plants. Other European
countries are dithering, and the cost of building nuclear plants is rising.
If you do not have an abundance of natural
gas, as here in the United States, then coal is your default choice. It is
shipped around the world in larger and larger quantities. The more the world
has resisted the burning of coal, the more it has had to fall back on it.
Alternative energy, attractive in theory, is yet to make its mark.
Because coal has always had an
environmental price, it has always been under attack, and at the same time it
has proven stubbornly hard to replace. King Edward I of England, who reigned
from 1239 to 1307, was the first known major opponent of coal. He banned it in
1306.
Tales of why he did this vary. One story
goes that his mother, Queen Eleanor of Provence, when staying at Nottingham
Castle, was so affected by the coal fumes from the town that she had to move
out.
Wood was hard to come by in towns, and it
does not heat like coal. Anyway England was a cold place and wood was in short
supply, so the ban was not very effective, despite the fact that the death
penalty was standard for disobeying royal orders.
Two and a half centuries later, Queen
Elizabeth I tried to ban coal with not much effect. The prospect of a coal ban
was even more draconian then as her father, Henry VIII, had largely denuded the
English forests to build his navy and she was even more committed to sea power.
With the invention of the steam engine in
the early 1700s (ironically, it was originally intended to pump water out of
coal mines), the supremacy of coal for was guaranteed. It led directly to the
Industrial Revolution and coal’s preeminence as the fuel of the Industrial Age.
There was a price in mine disasters, mine fires that burn for decades, and air
pollution. But there were also huge benefits.
Britain led the way both in the use of
coal and its environmental costs. An industrial area in the Midlands was known
as the “Black Country.”
London fog was assumed to be just that,
fog, but it was smog. The smog was so bad that I can recall, in the winter of
1962, walking in the streets holding hands with strangers because you could not
see where you were going. So-called smokeless fuel – usually a kind of coke or
other high- carbon fuel -- ended that, and fog in London is now no worse than
it is elsewhere.
“Clean coal” has been the rallying call of
the industry for 30 or more years -- and coal is getting a lot cleaner in its
preparation, combustion and mining. The trick in combustion is higher
temperatures and pressures, described as supercritical and ultra-supercritical,
a technology China has embraced that increases the efficiency of coal, from a
historical 28 percent to around 50 percent with concomitant reductions in the
greenhouse gas per kilowatt.
Mining, too, has gotten safer in the
developed world with stricter regulation and better equipment. Quinn of the National
Mining Association says that reclamation after strip mining is better than it
ever has been. Yet the scars remain from an earlier time across all the coal-
producing states.
If, like Edward I, Elizabeth I and the
EPA, we cannot stop coal use, we better get behind the technologies and
regulations that reduce its impact, because King Coal looks set for a long,
long reign.
