Energy resources bring with them great social and economic promise, providing financial growth for communities and energy services for local economies. However, the infrastructure which delivers energy services can break down in an energy accident, sometimes causing considerable damage. Energy fatalities can occur, and with many systems deaths will happen often, even when the systems are working as intended.
Historically, coal mining has been the most dangerous energy activity and the list of historical coal mining disasters is a long one. Underground mining hazards include suffocation, gas poisoning, roof collapse and gas explosions. Open cut mining hazards are principally mine wall failures and vehicle collisions. In the US alone, more than 100,000 coal miners have been killed in accidents over the past century, [1] with more than 3,200 dying in 1907 alone. [2]
According to Benjamin K. Sovacool, 279 major energy accidents occurred from 1907 to 2007 and they caused 182,156 deaths with $41 billion in property damages, with these figures not including deaths from smaller accidents. [3]
However, by far the greatest energy fatalities as a result of energy generation by humanity are due to air pollution, primarily generated from the burning of fossil fuels and biomass. [4] Particulate matter (counting outdoor air pollution effects only) is estimated to cause 2.1 [5] [6] to 4.21 million deaths annually. [7] [8]
According to Benjamin K. Sovacool, while responsible for less than 1 percent of the total number of energy accidents, hydroelectric facilities claimed 94 percent of reported immediate fatalities. Results on immediate fatalities are dominated by one disaster in which Typhoon Nina in 1975 washed out the Shimantan Dam (Henan Province, China) and 171,000 people perished. [3] The other major accident that involved greater than 1000 immediate deaths followed the rupture of the NNPC petroleum pipeline in 1998 and the resulting explosion. [3] The other singular accident described by Sovacool is the predicted latent death toll of greater than 1000, as a result of the 1986 steam explosion at the Chernobyl nuclear reactor in Ukraine. With approximately 4000 deaths in total, to eventually result in the decades ahead due to the radio-isotope pollution released.
In the oil and gas industry, the need for improved safety culture and training within companies is evidenced by the finding that workers new to a company are more likely to be involved in fatalities. [9]
Coal mining accidents resulted in 5,938 immediate deaths in 2005, and 4746 immediate deaths in 2006 in China alone according to the World Wildlife Fund. [10] Coal mining is the most dangerous occupation in China, the death rate for every 100 tons of coal mined is 100 times that of the death rate in the US and 30 times that achieved in South Africa. Moreover, 600,000 Chinese coal miners, as of 2004, were suffering from Coalworker's pneumoconiosis (known as "black lung") a disease of the lungs caused by long-continued inhalation of coal dust. And the figure increases by 70,000 miners every year in China. [11]
Historically, coal mining has been a very dangerous activity and the list of historical coal mining disasters is a long one. In the US alone, more than 100,000 coal miners were killed in accidents over the past century, [1] with more than 3,200 dying in 1907 alone. [2] In the decades following this peak, an annual death toll of 1,500 miner fatalities occurred every year in the US until approximately the 1970s. [12] Coal mining fatalities in the US between 1990 and 2012 have continued to decline, with fewer than 100 each year. [13] (See more Coal mining disasters in the United States)
In the United States, in the 2000s, after three decades of regulation on the Environmental impact of the coal industry, including regulations in the 1970s and 1990s from the Clean Air Act, an act created to cut down on pollution related deaths from fossil fuel usage, US coal fired power plants were estimated, in the 2000s, to continue to cause between 10,000 and 30,000 latent, or air pollution related deaths per year, due to the emissions of sulfur dioxide, nitrogen oxides and directly emitted particulate matter that result when coal is burnt. [14]
According to the World Health Organization in 2012, urban outdoor air pollution, from the burning of fossil fuels and biomass is estimated to cause 3 million deaths worldwide per year and indoor air pollution from biomass and fossil fuel burning is estimated to cause approximately 4.3 million premature deaths. [15] In 2013, a team of researchers estimated the number of premature deaths caused by particulate matter in outdoor air pollution as 2.1 million, occurring annually. [5] [6]
According to Benjamin Sovacool, nuclear power plants rank first in terms of their economic cost, accounting for 41 percent of all property damage. Oil and hydroelectric follow at around 25 percent each, followed by natural gas at 9 percent and coal at 2 percent. [3] Excluding Chernobyl and the Shimantan Dam, the three other most expensive accidents involved the Exxon Valdez oil spill (Alaska), The Prestige oil spill (Spain), and the Three Mile Island nuclear accident (Pennsylvania). [3] However analysis presented in the international Journal, Human and Ecological Risk Assessment found that coal, oil, Liquid petroleum gas and hydro accidents have cost more than nuclear power accidents. [16]
Modern-day U.S. regulatory agencies frequently implement regulations on conventional pollution if one life or more is predicted saved per $6 million to $8 million of economic costs incurred. [17]
A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, or a reactor core melt. The prime example of a "major nuclear accident" is one in which a reactor core is damaged and significant amounts of radioactive isotopes are released, such as in the Chernobyl disaster in 1986 and Fukushima nuclear disaster in 2011.
An environmental disaster or ecological disaster is defined as a catastrophic event regarding the natural environment that is due to human activity. This point distinguishes environmental disasters from other disturbances such as natural disasters and intentional acts of war such as nuclear bombings.
A mining accident is an accident that occurs during the process of mining minerals or metals. Thousands of miners die from mining accidents each year, especially from underground coal mining, although accidents also occur in hard rock mining. Coal mining is considered much more hazardous than hard rock mining due to flat-lying rock strata, generally incompetent rock, the presence of methane gas, and coal dust. Most of the deaths these days occur in developing countries, and rural parts of developed countries where safety measures are not practiced as fully. A mining disaster is an incident where there are five or more fatalities.
The natural environment, commonly referred to simply as the environment, is all living and non-living things that occur naturally on Earth or some part of it. This includes complete ecological units that function as natural systems without massive human intervention, including all vegetation, animals, microorganisms, rocks, atmosphere and natural phenomena that occur within their boundaries. And it includes universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from human activity.
Petroleum transport is the transportation of petroleum and derivatives such as gasoline (petrol). Petroleum products are transported via rail cars, trucks, tanker vessels, and pipeline networks. The method used to move the petroleum products depends on the volume that is being moved and its destination. Even the modes of transportation on land such as pipeline or rail have their own strengths and weaknesses. One of the key differences are the costs associated with transporting petroleum though pipeline or rail. The biggest problems with moving petroleum products are pollution related and the chance of spillage. Petroleum oil is very hard to clean up and is very toxic to living animals and their surroundings.
Nuclear power has various environmental impacts, both positive and negative, including the construction and operation of the plant, the nuclear fuel cycle, and the effects of nuclear accidents. Nuclear power plants do not burn fossil fuels and so do not directly emit carbon dioxide. The carbon dioxide emitted during mining, enrichment, fabrication and transport of fuel is small when compared with the carbon dioxide emitted by fossil fuels of similar energy yield, however, these plants still produce other environmentally damaging wastes. Nuclear energy and renewable energy have reduced environmental costs by decreasing CO2 emissions resulting from energy consumption.
Fawley Refinery is an oil refinery located at Fawley, Hampshire, England. The refinery is owned by Esso Petroleum Company Limited, a subsidiary of Exxon Mobil Corporation, which acquired the site in 1925. Situated on Southampton Water, it was rebuilt and extended in 1951 and is now the largest oil refinery in the United Kingdom, and one of the most complex refineries in Europe. With a capacity of 270,000 barrels (43,000 m3) per day, Fawley provides 20 per cent of the UK's refinery capacity. Over 2,500 people are employed at the site.
The following are lists of disasters.
The health and environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products. In addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas desulfurization sludge, that contain mercury, uranium, thorium, arsenic, and other heavy metals. Coal is the largest contributor to the human-made increase of carbon dioxide in Earth's atmosphere.
The environmental impact of the energy industry is significant, as energy and natural resource consumption are closely related. Producing, transporting, or consuming energy all have an environmental impact. Energy has been harnessed by human beings for millennia. Initially it was with the use of fire for light, heat, cooking and for safety, and its use can be traced back at least 1.9 million years. In recent years there has been a trend towards the increased commercialization of various renewable energy sources. Scientific consensus on some of the main human activities that contribute to global warming are considered to be increasing concentrations of greenhouse gases, causing a warming effect, global changes to land surface, such as deforestation, for a warming effect, increasing concentrations of aerosols, mainly for a cooling effect.
Coal mining has historically been an important industry in Ukraine. Although the industry is often associated with the coal-rich Donets basin in the east of the country, other coal mining regions include the Lviv-Volhynian basin and the Dnieper brown coal mining basin. The Donets basin is Ukraine's most developed and largest coal mining region.
Fossil fuel regulations are part of the energy policy in the United States and have gained major significance with the nation's strong dependence on fossil fuel-based energy. Regulatory processes are established at the federal and state level due to the immense economic, socio-political and environmental impact of fossil fuel extraction and production. Over 80% of the United States' energy comes from fossil fuels such as coal, natural gas, and oil. The Bush administration was marked by the Energy Policy Act of 2005, which provided a monetary incentive for renewable energy adoption and addressed the issue of climate change. The Obama administration was made up of advocates for renewable energy and natural gas, while Donald Trump built his campaign on promises to revive the coal industry.
