NOTE: On Monday, June 2 the Environmental Protection Agency (EPA) released a long-expected rule proposal that seeks by 2030 to reduce America’s carbon dioxide emissions 30% from 2005 levels. The primary mechanism for the reduction will be tough emissions limits on coal-fired power plants. The effect of the rule will most likely be the dramatic expansion of natural gas as a fuel for power generation. When burned, gas emits just half the carbon of coal.
(from an Associated Press story at NY Post) NEW YORK – Electricity prices are probably on their way up across much of the US as coal-fired plants, the dominant source of cheap power, shut down in response to environmental regulations and economic forces.
New and tighter pollution rules and tough competition from cleaner sources such as natural gas, wind and solar will lead to the closings of dozens of coal-burning plants across 20 states over the next three years. And many of those that stay open will need expensive retrofits [to comply with new regulations imposed by the Obama administration].
Because of these and other factors, the Energy Department predicts retail power prices will rise 4 percent on average this year, the biggest increase since 2008. By 2020, prices are expected to climb an additional 13 percent, a forecast that does not include the costs of the environmental [regulations unveiled by the Obama administration on Monday].
…State governments and industry are struggling to balance this push for a cleaner environment with the need to keep the grid reliable and prevent prices from rocketing too much higher.
“We’re facing a set of questions that are new to the industry,” says Clair Moeller, who oversees transmission and technology for the Midcontinent Independent System Operator [MISO], which coordinates much of the electric grid between Minnesota and Louisiana.
Coal is…used to produce 40 percent of the nation’s electricity, more than any other fuel. Because it is cheap and abundant and can be stored on power plant grounds, it helps keep prices stable and power flowing even when demand spikes.
Natural gas, which accounts for 26 percent of the nation’s electricity, has dropped in price and become more plentiful because of the fracking boom. But its price is on the rise again, and it is still generally more expensive to produce electricity with gas than with coal. Also, gas isn’t stored at power plants because the cost is prohibitive. That means it is subject to shortages and soaring prices.
During the brutally cold and snowy winter that just ended, utilities in several states struggled to secure natural gas because so much was also needed to heat homes. Some utilities couldn’t run gas-fired plants at all, and power prices soared 1,000 percent in some regions.
As Indiana has reduced its reliance on coal to 84 percent from 97 percent over the last decade, its power prices rose far faster than those of its neighbors and the rest of the country.
That makes things tough on customers, especially big power users like Rochester Metal Products Corp., in Rochester, Indiana. The hulking furnaces it uses to melt scrap iron consume enough electricity to power 7,000 households.
“As Indiana’s price of electricity becomes less and less competitive, so do we,” says Doug Smith, the company’s maintenance and engineering manager.
Burning coal releases toxic chemicals, soot and smog-forming chemicals, as well as twice the amount of carbon dioxide that natural gas produces. The Supreme Court last month gave an important approval to one Environmental Protection Agency clean-air rule. That cleared the way for a new rule… announced by President Barack Obama [this week].
This rule, the first to govern emissions of carbon dioxide from existing power plants, will accelerate the move away from coal – if it survives the legal and political challenges that are sure to come.
Already, the current rules are expected to force power companies to shut down 68 coal plants across 20 states between 2014 and 2017, according to Bentek Energy, a market analysis firm.
The Energy Department estimates coal plants with the output to supply 33 million homes will close by 2020.
“We haven’t operated at those low levels (of generation) for at least 30 years,” says MISO’s Clair Moeller.
To meet high demand this past winter, American Electric Power, which serves 5 million customers in 11 states, needed to run 89 percent of the coal plants it will soon have to shut down, says AEP CEO Nick Akins.
This raises concerns that the power system soon won’t have enough wiggle room to handle extreme weather, making blackouts more likely.
“It’s a warning of what may be to come,” Moeller says.
EPA administrator Gina McCarthy, responding to critics, notes that pollution also imposes costs on the economy because it harms human health and the environment. And she has also forcefully promised that the coming carbon dioxide rule will keep costs in check and power flowing.
“EPA is not going to threaten electric reliability,” she told a gathering of executives in Houston in March. “That is our No. 1 priority.” …

Global warming is an important issue to understand. The theory that man’s use of fossil fuels (burning coal, oil and gas for energy, which produces carbon dioxide, or CO2) is causing an imminent catastrophic change in the climate – global warming – is believed to be true by many scientists, climatologists, citizens, the mainstream media and Hollywood celebrities, and was made popular by former Vice President Al Gore’s movie “An Inconvenient Truth.” and called "a fact" by President Obama. People who believe in this theory say we must reduce the amount of carbon dioxide produced by limiting/reducing the amount of fossil fuels we use, or by purchasing offsets (carbon credits).
The belief that man’s activities are NOT causing an imminent catastrophic change in the climate is held by many other scientists (see MIT’s Professor of Meteorology Dr. Richard Lindzen’s commentary in Newsweek). This view is very unpopular in the media and widely condemned by those who believe man-made global warming is fact. See Newsweek magazine’s online presentation “The Global Warming Deniers.” Those who do not believe man is causing the global temperature to rise don’t believe it is necessary to reduce the production of CO2 by reducing our use of fossil fuels or to purchase carbon offsets.
