Fossil fuels are the major energy source that are being used in the world today. But there over-consumption can lead to serious environmental issues such as air pollution. Fossil fuels release carbon dioxide, nitrogen dioxide, sulfur dioxide, carbon monoxide etc.
Disadvantages of using fossil fuels
Coal and oil release sulfur dioxide gas when they burn, which causes breathing problems for living creatures and contributes to acid rain. Fossil fuels release carbon dioxide when they burn, which adds to the greenhouse effect and increases global warming .The disadvantages of fossil fuels are as follows: (a)Burning of fossil fuels produces oxides of carbon, nitrogen, sulphur, etc. that cause acid rain, which affects the soil fertility and water. (b)Burning of fossil fuels produce gases such as carbon dioxide that causes global warming.
Fossil fuels are of great importance because they can be burned (oxidized to carbon dioxide and water), producing significant amounts of energy per unit mass. The use of coal as a fuel predates recorded history. Coal was used to run furnaces for the smelting of metal ore.
Air pollution
Burning fossil fuels emits a number of air pollutants that are harmful to both the environment and public health. Acid rain is formed when sulfur dioxide and nitrogen oxides mix with water, oxygen, and other chemicals in the atmosphere, leading to rain and other precipitation that is mildly acidic.Fossil Fuels Pros and Cons
- 1 Well Developed. The technology we use to harness the energy in fossil fuels is well developed.
- 2 Cheap and Reliable. Fossil fuels are cheap and reliable sources of energy.
- 1 Contribute to Global Warming. Fossil fuels are not green sources of energy.
- 2 Non-Renewable.
- 3 Unsustainable.
- 4 Incentivized.
- 5 Accidents Happen.
Burning Fossil Fuels
When we burn oil, coal, and gas, we don't just meet our energy needs—we drive the current global warming crisis as well. Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change.Coal is the single biggest contributor to anthropogenic climate change. The burning of coal is responsible for 46% of carbon dioxide emissions worldwide and accounts for 72% of total greenhouse gas (GHG) emissions from the electricity sector.
Coal and Air Pollution
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.Coal contains the most CO2 per BTU, the largest contributor to global warming. Severe environmental, social and health and safety impacts of coal mining. Devastation of environment around coal mines. High cost of transporting coal to centralized power plants.
Coal impacts: air pollution
When coal is burned it releases a number of airborne toxins and pollutants. They include mercury, lead, sulfur dioxide, nitrogen oxides, particulates, and various other heavy metals.When coal is burned for energy, carbon dioxide is released into the atmosphere. The higher the concentration of greenhouse gases, the more energy trapped in the atmosphere. With more energy trapped, the planet warms, contributing to climate change.
The sale of coal for domestic use will be banned by 2023 the government will announce, in its bid to combat air pollution. Both products will be completely banned by February 2023. But responding to the plans, coal merchants insisted that households burning coal could see a 30-50 per cent rise in the annual fuel bill.
As of 2010, coal accounted for 43% of global greenhouse gas emissions from fuel combustion. Simply put, to solve the climate crisis we must stop burning coal. Job number one is retiring old coal plants. Carbon dioxide (CO2) is the main greenhouse gas, and is the leading cause of global warming.
To keep within sight of the Paris Agreement target of restricting global warming to “well below 2oC”, coal burning for power must decline rapidly, leaving the energy systems of advanced economies by 2030, and of developing economies by 2050.
The mercury released by burning coal is converted into a far more toxic form when it enters the food chain. Mercury is released into the air from a coal-fired power plant, and falls to the ground with snow and rain. From there, it drains into watersheds, rivers, and lakes and settles into sediment.
Air Pollution
Fossil fuels cause environmentally unsafe compounds to form in the atmosphere, depleting ozone levels and thus creating a spike in skin cancer rates. Burning coal releases sulfur oxide while the combustion of car engines and power plants gives off nitrogen oxides, which cause smog.Burning fossil fuels like coal, oil, and gas results in carbon pollution, which causes climate change. So if we want to stop climate change (and avoid devastating extreme weather, sea level rise wiping out communities, global conflict and instability, etc.), we have to stop burning fossil fuels.
In order to project how much time we have left before the world runs out of oil, gas, and coal, one method is measuring the R/P ratios — that is the ratio of reserves to current rates of production. At the current rates of production, oil will run out in 53 years, natural gas in 54, and coal in 110.
Nearly 15 billion metric tons of fossil fuels are consumed every year. Three countries use more fossil fuels than the rest of the world combined: China, the United States, and India.
