Inequality isn t just a matter of income: it plays out in carbon pollution as well. It turns out a mere one percent of U.S. power plants account for over 12 percent of all U.S. carbon emissions and for about 30 percent of U.S. power sector emissions. That s from  by Environment America,[http://www.wikifx.ru/index.php/%D0%A3%D1%87%D0%B0%D1%81%D1%82%D0%BD%D0%B8%D0%BA:Etlzmsay7#Jets_place_Mark_Sanchez_injured_reserve.2C_designated_to_retur Jets place Mark Sanchez injured reserve, designated to retur], which highlights just how much sheer age and inertia have added to U.S. carbon pollution.

That one percent is actually 50 plants, all of them coal-fired. In fact,[http://norn-rpg.altenbach-it.net/wiki/index.php?title=Benutzer:Cibvpyrr3#Where_does_Hochevar_fit_in_Royals.C2.92_future-_To_be_decide Where does Hochevar fit in Royals’ future- To be decide], America s single dirtiest power plant Georgia Power’s Plant Scherer dumped over 21 million metric tons (MMT) of carbon dioxide into the atmosphere in 2011. That s more than all the energy-related emissions produced by the state of Maine that year.
 +
And the disproportionate contribution of the dirtiest plants to greenhouse gas emissions continues on down the scale: in 2011, half of all the power sector s carbon emissions came from the 100 dirtiest plants (98 of which are coal-fired). And 90 percent of all those emissions came from just the 500 dirtiest power plants. That s out of almost 6,000 electricity generating facilities renewable and fossil-fuel-powered alike in the country.

All told,[http://sugarforum.jp/wiki/%E5%88%A9%E7%94%A8%E8%80%85:Eittlwjug6#Twitter_growth_off Twitter growth off], the 50 dirtiest power plants make up a sizable chunk of all U.S. carbon emissions:

According to Environment America s numbers,[http://jgsyhg.net/Review.asp?NewsID=405 U.S. and Russia reach agreement on Syria weapons], to do its part in keeping global warming under two degrees Celsius, the United States will need to get its carbon emissions down 25 to 40 percent below 1990 s levels by 2020. And simply eliminating the carbon pollution produced by those 50 plants by either replacing them with renewable sources or eliminating demand through improved energy efficiency could bring those emissions down to 11 percent below 1990 levels. A major piece of the goal.

The reasons these plants produce such an outsized share of the greenhouse gas problem boil down to age and inefficiency. Three-fourths of U.S. coal plants  in 2012 the designed lifetime limit for most coal plants. But in many instances, coal companies have chosen to retrofit the plants to keep them going. About half the plants range from 40 to 60 years old, making them horribly inefficient and prone to the dirtiest levels of carbon pollution.
 +
All of which stands as yet another reason to move forward with the Obama Administration s  for both new and existing power plants. As a Bloomberg Editorial ,[http://eproc-wiki.lkpp.go.id/wiki/User:Ydjabhqbi3#Bleacher_Report_Most_Terrifying_Likenesses_in_Sports_Figures Bleacher Report Most Terrifying Likenesses in Sports Figures], coal-fired power plants have been sitting on their laurels when it comes to technology upgrades. The regulations will force them to take on the carbon sequestration and clean coal technologies, as well as plant upgrades and efficiency improvements, they should ve been moving towards already.
 +
As this latest report makes obvious, there s a lot of low hanging fruit to pick here.
