Ontario Shuts Its Coal Plants
April 2nd, 2013As recently as 2007, the Energy Information Administration (EIA), a research unit of the U.S. Department of Energy, projected that the fuel mix for producing electricity in the U.S. would persist largely unchanged through 2035. According to that estimate, a little more than half of the country’s electricity would come from coal, about 20 percent from nuclear plants, and a little less than 20 percent from natural gas; the balance, roughly 12 percent, would be generated from wind, solar, biomass, and hydropower.
A lot changed over the last five years. In 2012, according to the EIA, U.S. utilities burned 815 million tons of coal for electricity, down from over 1 billion tons in 2005, and the lowest utility coal consumption since 1990. Less than 38 percent of the country’s electricity last year came from coal. As recently as 2009 it was 53 percent. In its most recent assessment, the EIA projects that 49,000 megawatts of coal-fired power — equal to 50 big plants, and 15 percent of existing coal-fired capacity in 2012 – will be retired over the next seven years.
Replacing coal is a surge of plants fueled by natural gas and wind. Last year, gas supplied 29.9 percent of U.S. electricity, up from 23 percent in 2009. And in 2012, with 13.2 megawatts installed nationally (equivalent to 13 big coal-fired plants), wind energy accounted for 42 percent of the nation’s new electrical generating capacity, more than coal and natural gas combined. Texas, of all places, generates over 9 percent of its electricity with 12,200 megawatts of installed wind capacity.
The U.S. transition to cleaner energy sources, particularly in the electrical sector, reflects a trend unfolding with gathering momentum in many industrialized nations.
Electricity generated from renewable energy sources contributed almost one fifth — 19.9 percent — of the European Union’s electricity in 2010, according to commission statistics. From 2000 to 2010, the number of gigawatts of electricity generated from biomass in EU nations more than tripled. During the same decade, the number of gigs generated by wind turbines increased almost seven-fold. A gigawatt is 1 billion watts.
Now comes Ontario, Canada and a new narrative of electrical transition that pushes the envelope of what is possible in the drive to quit the coal-fired power generating business. I’ve reported on the provincial energy program in 2007 here on ModeShift. Today Yale Environment 360 posted my newest piece on Ontario’s transition to cleaner energy sources.
By most measures of environmental policy and progress, Ontario, Canada ranks well. Over the last half-century, Canada’s most populous province required cities and industries to treat every gallon of wastewater, dramatically reduced the level of sulfur and other pollutants that caused acid rain, and convinced the big and politically powerful pulp and paper industry to install state-of-the-art emissions control equipment.
Next year, though, Ontario is scheduled to complete a 21st century environmental cleanup project that distinguishes it among North American jurisdictions. After a decade of work by the Liberal Party government, Ontario at the end of this year is scheduled to close the last of its big coal-fired generators, and leave a single small coal-fired unit available during periods of peak electrical demand until it closes next year. In shutting down the province’s 19 boilers fueled by coal, Ontario will become the first industrial region on the continent to eliminate coal-fired generation.
