Possible environmental effects: environmental groups have raised concerns that CSG development might cause environmental damage through release of untreated production water at the surface; damage to, and contamination of underground aquifers by hydraulic fracturing; damage to wildlife habitat in sensitive areas and …
Is coal seam gas good or bad?
Coal seam gas is bad for the environment and we should all protest against its use. Genetically modified foods are a part of multinational plans to take over the world’s food supply. Wind farms are dangerous to human health and should be restricted.
Is coal seam gas the same as fracking?
Coal seam gas (CSG) and the gas that comes from shales are chemically very similar. They generate the same amount of heat and CO₂ when burned in your heater or at an electricity power plant. … Shale reservoirs always require fracking, while perhaps only half of coal seam gas reservoirs require fracture stimulation.
What is coal seam gas made of?
Coal seam gas (CSG) is primarily methane – a colourless and odourless gas, found in coal deposits formed over millions of years from fallen trees and other plant matter. Natural gas collects in underground coal seams by bonding to the surface of coal particles.
How does coal affect the environment in Australia?
Coal is a major source of rising greenhouse gas causing climate change. The burning of coal emits hazardous air pollutants, including particulate matter, sulphur dioxide, nitrogen oxides, carbon dioxide, mercury and arsenic. Australia has one of the most carbon intensive and polluting electricity supplies in the world.
Why is gas bad for the environment?
Gasoline use contributes to air pollution
The vapors given off when gasoline evaporates and the substances produced when gasoline is burned (carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons) contribute to air pollution. Burning gasoline also produces carbon dioxide, a greenhouse gas.
Why is coal seam gas so controversial?
Coal seam gas (CSG) is a polarising issue in some communities. Proponents argue that CSG is a vital energy resource, necessary for continued gas supply. Opponents claim that CSG could have serious environmental and social impacts.
Why is coal seam gas good?
Using CSG to generate electricity reduces CO2 emissions by up to 70 per cent compared with coal, and gas is critical to us meeting our greenhouse reduction targets. Gas is also the perfect partner to back up intermittent renewable energy sources such as wind or solar.
Is coal seam gas renewable?
Coal seam gas is a non-renewable energy resource that is a by-product of coal. It is a ‘pure’ and ‘non-toxic’ gas and for this reason has attracted a lot of commercial interest. During the process of coal formation, biogenic and thermogenic methane gas forms.7 мая 2012 г.
Is fracking used to extract coal?
FRACKING & MINING: The processes used to extract and transport minerals, metals, coal, and natural gas. … Fracking can contaminate groundwater, deplete freshwater supply, and the development of pipelines to transport natural gas could cause construction and erosion across large swaths of land.
How is coal formed?
Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
What is a seam of coal?
: a bed of coal usually thick enough to be profitably mined.
For what coal is used?
Coal is primarily used as fuel to generate electric power in the United States. The coal is burned and the heat given off is used to convert water into steam, which drives a turbine.
Why is coal so bad for the environment?
The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion.
Why is coal power bad?
Air pollution from coal-fired power plants is linked with asthma, cancer, heart and lung ailments, neurological problems, acid rain, global warming, and other severe environmental and public health impacts.
Why coal mining is bad for the environment?
Emissions from burning coal
Nitrogen oxides (NOx), which contribute to smog and respiratory illnesses. Particulates, which contribute to smog, haze, and respiratory illnesses and lung disease. Carbon dioxide (CO2), which is the primary greenhouse gas produced from burning fossil fuels (coal, oil, and natural gas)
