Why is coal bad for the environment

2022.01.12 23:54




















Even after operations cease, the nutrient-leached land will never return to what it once was. As a result, critical wildlife habitat —land crucial for breeding and migration —ends up fragmented and destroyed. Coal, oil, and gas development pose myriad threats to our waterways and groundwater. Coal mining operations wash acid runoff into streams, rivers, and lakes and dump vast quantities of unwanted rock and soil into streams.


Oil spills and leaks during extraction or transport can pollute drinking water sources and jeopardize entire freshwater or ocean ecosystems. Fracking and its toxic fluids have also been found to contaminate drinking water, a fact that the Environmental Protection Agency was slow to recognize. Meanwhile, all drilling, fracking, and mining operations generate enormous volumes of wastewater , which can be laden with heavy metals, radioactive materials, and other pollutants.


Industries store this waste in open-air pits or underground wells that can leak or overflow into waterways and contaminate aquifers with pollutants linked to cancer, birth defects, neurological damage, and much more. Indeed, some These include benzene linked to childhood leukemia and blood disorders and formaldehyde a cancer-causing chemical. Mining operations are no better, especially for the miners themselves, generating toxic airborne particulate matter.


Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change.


In the United States, the burning of fossil fuels, particularly for the power and transportation sectors , accounts for about three-quarters of our carbon emissions. Fossil fuels emit more than just carbon dioxide when burned.


Coal-fired power plants singlehandedly generate 42 percent of dangerous mercury emissions in the United States, as well as two-thirds of U. Meanwhile, fossil fuel—powered cars, trucks, and boats are the main contributors of poisonous carbon monoxide and nitrogen oxide , which produces smog and respiratory illnesses on hot days.


Our seas absorb as much as a quarter of all man-made carbon emissions. Since the start of the Industrial Revolution and our coal-burning ways , the ocean has become 30 percent more acidic.


As the acidity in our waters goes up, the amount of calcium carbonate—a substance used by oysters, lobsters, and countless other marine organisms to form shells—goes down. This can slow growth rates, weaken shells, and imperil entire food chains.


Ocean acidification impacts coastal communities as well. State and federal incentives, along with falling prices, are pushing our nation —and the world —toward cleaner, renewable energy sources such as wind and solar.


Renewables are on track to become a cheaper source of energy than fossil fuels, which is spurring a boom in clean energy development and jobs. Significantly higher levels of renewables can be integrated into our existing grid, though care must be taken to site and build renewable energy responsibly.


It accounts for more than 2. If we can put the right policies in place, we are poised to make dramatic progress toward a clean energy future. To do that, we will need to cut energy demand in half, grow renewable energy resources so that they provide at least 80 percent of our power, electrify almost all forms of transportation, and get fossil fuels out of our buildings. That will require sustained, coordinated policy efforts from all levels of government, the private sector, and local communities.


But we know we can do it using the proven, demonstrated clean energy technologies that we have today. Distrust in the TVA runs deep in eastern Tennessee, and as the utility shutters two power plants—Bull Run and Kingston—local activists fear it will close up shop without safely containing its leaky pits of toxic sludge and ash.


The study discussed a number of other impacts that are not easily quantified, including effects of heavy metal toxins and carcinogens released into water supplies as part of coal mining and processing; the death and injury of workers mining coal ; and the social impacts in mining communities.


Skeptical Science notes that when the coal externalities of the study are included in coal's price, it increases the levalized costs to approximately 28 cents per kWh, which is more than the U. Energy Information Administration cost of hydroelectric, wind onshore and offshore , geothermal, biomass, nuclear, natural gas, and solar photovoltaics, and is on par with solar thermal, although the costs of solar thermal are falling.


The study noted that its estimates did not include the full cost of coal: [53]. Log in Request account. Navigation Main page. Recent changes. Random page. Help about MediaWiki.

Metz et al. New York: Cambridge University Press, Researchers say they need to know more about how buried carbon dioxide behaves to be sure it won't leak back out—a potential threat to climate or even people.


But Friedmann says, "For a first cut, we have enough information to say, 'It's a no-brainer. We know how to do this. Yet that's no guarantee utilities will embrace the gasification technology. The two gasification power plants in the U. The technology also costs as much as 20 percent more. Most important, there's little incentive for a company to take on the extra risk and expense of cleaner technology: For now U.


Cinergy CEO James Rogers, the man in charge of Gibson and eight other carbon-spewing plants, says he expects that to change. I believe it's very important that we develop the ability to do carbon sequestration. The energy bill passed last July by the U. Congress offers help in the form of loan guarantees and tax credits for gasification projects. The experience of building and running the first few plants should lower costs and improve reliability. And sooner or later, says Rogers, new environmental laws that put a price on carbon dioxide emissions will make clean technology look far more attractive.


If he's right, we may one day be able to cool our houses without turning up the thermostat on the entire planet. All rights reserved. Share Tweet Email.
