Europe Turns Back to Coal, Raising Climate Fears

CIVITAVECCHIA, Italy — At a time when the world’s top climate experts agree that carbon emissions must be rapidly reduced to hold down global warming, Italy’s major electricity producer, Enel, is converting its massive power plant here from oil to coal, generally the dirtiest fuel on earth.

Italy’s Civitavecchia power plant is converting from oil to coal.
Over the next five years, Italy will increase its reliance on coal to 33 percent from 14 percent. Power generated by Enel from coal will rise to 50 percent.
And Italy is not alone in its return to coal. Driven by rising demand, record high oil and natural gas prices, concerns over energy security and an aversion to nuclear energy, European countries are expected to put into operation about 50 coal-fired plants over the next five years, plants that will be in use for the next five decades.
In the United States, fewer new coal plants are likely to begin operations, in part because it is becoming harder to get regulatory permits and in part because nuclear power remains an alternative. Of 151 proposals in early 2007, more than 60 had been dropped by the year’s end, many blocked by state governments. Dozens of other are stuck in court challenges.
The fast-expanding developing economies of India and China, where coal remains a major fuel source for more than two billion people, have long been regarded as among the biggest challenges to reducing carbon emissions. But the return now to coal even in eco-conscious Europe is sowing real alarm among environmentalists who warn that it is setting the world on a disastrous trajectory that will make controlling global warming impossible.
They are aghast at the renaissance of coal, a fuel more commonly associated with the sooty factories of Dickens novels, and one that was on its way out just a decade ago.
There have been protests here in Civitavecchia, at a new coal plant in Germany, and at one in the Czech Republic, as well as at the Kingsnorth power station in Kent, which is slated to become Britain’s first new coal-fired plant in more than a decade.
Europe’s power station owners emphasize that they are making the new coal plants as clean as possible. But critics say that “clean coal” is a pipe dream, an oxymoron in terms of the carbon emissions that count most toward climate change. They call the building spurt shortsighted.
“Building new coal-fired power plants is ill conceived,” said James E. Hansen, a leading climatologist at the NASA Goddard Institute for Space Studies. “Given our knowledge about what needs to be done to stabilize climate, this plan is like barging into a war without having a plan for how it should be conducted, even though information is available.
“We need a moratorium on coal now,” he added, “with phase-out of existing plants over the next two decades.”
Coal’s Advantages
Enel and many other electricity companies say they have little choice but to build coal plants to replace aging infrastructure, particularly in countries like Italy and Germany that have banned the building of nuclear power plants. Fuel costs have risen 151 percent since 1996, and Italians pay the highest electricity costs in Europe.
In terms of cost and energy security, coal has all the advantages, its proponents argue. Coal reserves will last for 200 years, rather than 50 years for gas and oil. Coal is relatively cheap compared with oil and natural gas, although coal prices have tripled in the past few years. More important, dozens of countries export coal — there is not a coal cartel — so there is more room to negotiate prices.
“In order to get over oil, which is getting more and more expensive, our plan is to convert all oil plants to coal using clean-coal technologies,” said Gianfilippo Mancini, Enel’s chief of generation and energy management. “This will be the cleanest coal plant in Europe. We are hoping to prove that it will be possible to make sustainable and environmentally friendly use of coal.”
“Clean coal” is a term coined by the industry decades ago, referring to its efforts to reduce local pollution. Using new technology, clean coal plants sharply reduced the number of sooty particles spewed into the air, as well as gases like sulfur dioxide and nitrous oxide. The technology has minimal effect on carbon emissions.
