What is bad about shale gas?
But US researchers found that shale gas wells leak substantial amounts of methane, a potent greenhouse gas. This makes its climate impact worse than conventional gas, they say – and probably worse than coal as well.
What is the problem with shale oil?
The production of oil from shales has a potentially serious impact on the environment. Four specific areas of concern dominate discussion regarding development of the resource: greenhouse gas output, water consumption and pollution, surface disturbance, and socioeconomic effects.
Why has it been so difficult to extract natural gas from shale in the past?
Shale is a tightly packed sedimentary rock. The shale is very porous, but it is not very permeable. This allows the shale to hold a lot of oil/natural gas but makes it difficult to remove those energy sources.
What is fracking negative?
Air pollution and water contamination due to the toxic chemicals used in hydraulic fracturing are the greatest concerns within fracking sites, while the need for wastewater disposal and shrinking water supplies are also pressing issues directly related to the procedure.
How bad is shale oil for the environment?
Surface mining of oil shale deposits causes the usual environmental impacts of open-pit mining. In addition, the combustion and thermal processing generate waste material, which must be disposed of, and harmful atmospheric emissions, including carbon dioxide, a major greenhouse gas.
Is shale good for the environment?
As methane is more than 20 times as powerful a greenhouse gas as carbon dioxide, shale gas is likely to prove more harmful in climate change terms than even coal, which is usually regarded as the dirtiest fossil fuel.
Why is fracking done?
Fracking allows drilling firms to access difficult-to-reach resources of oil and gas. In the United States it has significantly boosted domestic oil production and driven down gas prices. The industry suggests fracking of shale gas could contribute significantly to the UK’s future energy needs.
