Infographic: The Impacts of Natural Gas on Public Health and the Environment. When this occurs, CO2, carbon monoxide, sulfur dioxide, nitrogen oxides, and other compounds are shot into the atmosphere. Within 15 20 minutes fish exposed to such concentrations show signs of acute poisoning, and they die within 1-2 days of exposure. As drilling for natural gas pushes more and more into shale formations in populated areas, the problem of gas bubbling into drinking water is occurring with increasing frequency. Natural gas is cheaper than propane, but you shouldn't base the decision between the two solely on price. ConocoPhillips, a natural gas company, will tell you that when natural gas is burned, it produces mostly carbon dioxide and water vapor, which is the same thing we humans produce when we exhale. 2. It is first cooled in large cryogenic tanks and converted to Liquified Natural Gas(LNG). Because of the chemicals used, surrounding water sources are also endangered and Human life is often at risk. During drilling and extraction of gas deposits from the sea floor, releases of gas into the marine environment are inevitable. It's formed from decayed organic material transformed by high temperatures and pressures over millions of years into bubbles of methane gas. After being refined into pure methane (dry), it's ready to be transported. Wildfire is a part of nature. Reliance on other Nations 11. Broadly speaking, however, there are five ways in which non-renewable energy sources impact our environment. Natural gas (also called fossil gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes.Usually low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also present. This deadly combination of gasses further increases global warming. It is expensive and is sometimes used in combination with fracking. Vehicles, barrels, boats and heavy equipment may also be flooded or crushed during the storm. Composition of Natural Gas. This article outlines the many reasons why fracking is anything but harmless. In cases of oil spillage, water and soil pollution as well gas blowouts may occur. Methane is also what makes natural gas so problematic, in terms of its environmental impact. It offers various environmental advantages over the other energy sources. While the evidence of groundwater contamination by drilling is mixed, there is more of a danger of contamination from poor transportation, storage and disposal practices of fracking wastewater. The U.S. alone has some 500,000 miles of pipeline. What you know as oil is actually called petroleum or crude oil and may exist as a combination of liquid, gas, and sticky, tar-like substances. There are some legitimate reasons to allow limited use of flaring. This technique requires specialized equipment and has a higher risk of error. However, Natural Gas contains 85-90% methane making it extremely dangerous to the environment. When methane leaks during transportation, it pollutes the surrounding soil and water sources. As the name suggests, this system distributes Natural Gas to the end consumers. Gas flaring, the deliberate open-air burning of natural gas, is a practice common in the largest shale oil plays where natural gas is a byproduct of oil extraction. Industries are well known for their tendencies to follow certain trends or patterns. Uses of natural gas. . The role that natural gas can play in the future of global energy is inextricably linked to its ability to help address environmental problems. Many proponents of Natural Gas refer to it as such ignoring the fact that it is neither renewable nor environmentally friendly. All Rights Reserved. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. . Should You Invest in Immersion Cooling Crypto Mining Container? From traveling around the world to learn and observe new cultures to writing about shark attack survival, you'll always get an interesting world class environmental approach. Despite its reputation, natural gas negatively impacts the environment and drives global warming. Fire also releases carbon dioxidea key greenhouse gasinto the atmosphere. In cases of oil spillage, water and soil pollution as well gas blowouts may occur. http://naturalgas.org/jobs/, Dendrochronology: What Tree Rings Tell Us About Past and Present, History of the Study of Climate Change in Field of Environmental Science. Spills and blowouts occur due to drilling equipment failure, corrosion of pipelines, human error, earthquakes, ice, storms, shipping accidents etc. Natural Gas was proven to release 50% less carbon dioxide than coal, reduce greenhouse emissions and be more cost-effective. What are some positive and negative effects of using oil? The gas is chilled to -260 , when it condenses into a liquid 1/600th the previous volume. Environmental impact of gas turbines. Occasionally, specially designed ships, trucks, or buses are used to transport Natural Gas. This often leads to toxic groundwater and can affect the areas animals and plants. Natural gas, like other energy sources, has an impact on the environment. At concentrations of 0.02 - 0.05 mg/l, gas will be sensed by fish and they will move away. Much research has been done on the effects of "natural gas"on climate change. A frequent writer for National Geographic and Smithsonian, David is an avid follower and learner of the environment. Pipeline failures are most commonly due to material or welding defects, but pipelines may also be hit by anchors or trawls, or affected by earthquakes or ground erosion. Skeeze/Pixabay. When. It is first cooled in large, and converted to Liquified Natural Gas(LNG). Extreme . Dependence on World Market Prices for Gas 12. Environmental microbiologists examine microbes as they relate to the environment - their effects on Our site does not feature every educational option available on the market. The EIA reports that natural gas produced at oil wells can contain high concentrations of toxic hydrogen sulfide, which is burned off at these sites. Unconventional sources are more challenging to extract because the gas is locked inside the sediment. Natural gas is a versatile and efficient fuel that is used in a wide variety of applications, including electricity generation, heating, and industrial uses. This method usually requires multiple wells causing surface erosion, land tremors and it is, . This is true, for the most part, but that CO2 is still an environmental hazard, one that renewable energy sources dont produce at all. 2. The natural gas drilling usually has effects on both the environment as well as the community as it affects the air, water and the soil as well as the people who live near the drilling locations. Natural gas is a non-renewable resource that comes with many consequences the extraction and production processes are destructive, and using it is just as harmful. However, fracking brings its own environmental costs. Shellfish are also killed by exposure to gas. Natural gas burns cleaner than other fossil fuels, producing half the carbon dioxide as coal and about a third less than oil. They attract fish and it is easy for sport fishers to catch them. Green Matters is a registered trademark. We aggressively advocate for and defend clean air standards for all industrial and energy sources, including shale gas, at both the state and federal level . Natural gas primarily consists of methane which is mostly hydrogen. The presence of methane also increases the concentration of other greenhouse gasses. http://www.eia.gov/cfapps/ipdbproject/IEDIndex3.cfm?tid=3&pid=3&aid=6 The burning of fossil fuels releases carbon dioxide into the atmosphere, increasing CO2 levels, trapping heat, and contributing to global climate change. This method often poisons the groundwater, threatening local ecosystems and wildlife. . Animals and plants release carbon dioxide when they respire, or breathe. This page explores policy issues associated with the . Environmental microbiology is a growing niche area related to environmental biology, but dealing with the biology of lifeforms too small to see with the naked eye. Maybe you remember the greenhouse effect from school. But just because it's cleaner doesn't mean its clean. Drilling a natural gas well on land may require clearing and leveling an area around the well site. Now considered cleaner and cheaper than coal, it supplies 22% of the world's energy, used in heating, electricity generation and even as engine fuel. http://www.forbes.com/sites/greatspeculations/2014/01/02/key-trends-impacting-natural-gas-prices-in-the-u-s/, (9) Without oxygen, you will be unable to breathe, resulting in a range of symptoms including: Headache Dizziness Nausea Eye and throat irritation Fatigue Breathing problems Pale skin or blisters from skin contact 2) Release of carbon monoxide This lethal combination affects ecosystems, threatens helpful microorganisms, and disrupts natural cycles. However, these estimates are based on combustion taking place in new, efficient facilities. In principle it is odorless. Changes to Earth's climate driven by increased human emissions of heat-trapping greenhouse gases are already having widespread effects on the environment: glaciers and ice sheets are shrinking, river and lake ice is breaking up earlier, plant and animal geographic ranges are shifting, and plants and trees are blooming sooner. According to The Wilderness Society, fracking has been known to poison or pollute groundwater and surface water sources, threaten local wildlife, and in some cases, cause explosions, fires, and even earthquakes. Because of this, changes in natural gas demand in one use (say, power plants) can directly influence the price of it in other uses (home heating or industry). Highly pressurized Natural Gas is transported along pipelines. Destruction of Habitats through Mining 7. Support our Work and Donate. Natural gas companies will need to discover new, unproved reserves and develop new ways to extract the natural gas in order to keep up with the increasing demand. Natural gas is fast becoming the norm in homes and industries with a yearly use of roughly 132 million Mcf. However consumption is growing every year and the EIA projects it will have doubled by 2040. During this process, vertical wells are, thousands of feet into the earth through water tables and shale rocks to reach the oil and gas. The following are some of the negative impacts of using fossil energy , these are real effects of fossil fuel to the environment. . In the North Sea, where fishes are bottom species, there has been a negative relationship between the number of oil and gas rigs and fish catches. Their goal is to move Natural Gas from processing plants to the centers of consumption. This is because, like propane, natural gas pipelines can cause fires and explosions when the natural gas ignites. Some fish, such as flounders, are more sensitive to gas than other species. https://www.chevron.com/operations/natural-gas, (3) However, this energy source is not without disadvantages and affects the environment negatively. In cases of pipe leakages, blowouts may occur and the groundwater becomes toxic and unusable. It's also heavily used in industrial applications, such as producing plastics and fertilizer. Natural gas affects the environment during transportation. Juveniles are more sensitive than older fish. Climate change. That said, even the most gas-friendly scientists will tell you that this is not a solution, not when natural gas still manages to belch CO2 into our already oversaturated atmosphere. When flammable gases are involved, the effects of an unforeseen accident can be devastating. Though first used to power street lights in the early 1800s, and for heating and cooking in the 1900s, it still lagged far behind coal and oil. What Types of Chemicals Are Used in Fracking? 7 Environmental Impacts of Natural Gas 1. The public-health impact ofclimate change and the future health care costs have not been calculated in the long-term environmental and economic effects of fracked gas use . This process only works for instances where the natural gas formation is directly below the Earths surface. , flow reduction in water bodies, and groundwater contamination. This last source is frequently in the headlines, thanks to advances in hydraulic fracturing, more commonly known as fracking. http://epa.gov/climatechange/ghgemissions/gases/ch4.html, (8) They serve as the intermediate in the transportation chain. This infographic was developed by USC Environmental Health Centers Community Engagement Program on Health and Environment and the Trade, Health, and Environment Impact Project partners. Exposure to Benzene and Related Compounds: https://ezblockchain.net/article/natural-gas-and-the-environment/. The Positive Impact of Natural Gas Power generation: Natural gas is widely used for energy and power generation; moreover natural gas burns more cleanly and does not provide soot. Ozone Depletion 6. Also, this fuel is less regulated as opposed to other fossil fuels and is gaining worldwide adoption. With the shift to renewable energy came an increase in the use of Natural Gas. (4), In its natural state (wet) natural gas is composed primarily of methane, with small percentages of heavier hydrocarbons, like ethane, butane and propane, and often water and other chemical compounds. This is divided into three systems: These systems are the beginning of the transportation chain. http://www.edfenergy.com/energyfuture/generation-gas, (6) In the developed countries of the world where emission control has become a high-profile issue this has had a significant effect on the choice of technology for new . Because of their availability, ease of transport, and facile conversion to convenient fuels, natural gas and petroleum are currently the . After conducting geological surveys to detect the presence of conventional gas fields, a gas company will drill down to extract the gas. Natural gas exploration, drilling, and production affects the environment When geologists explore for natural gas deposits on land, they may disturb vegetation and soil with their vehicles. Source: Union of Concerned Scientists. The secret to fossil fuels' ability to produce energy is that they contain a large amount of carbon. Natural gas emits 50 to 60 percent less carbon dioxide (CO 2) when combusted in a new, efficient natural gas-power plant compared with emissions from a typical new coal plant. This infographic was developed by USC Environmental Health Centers Community Engagement Program on Health and Environment and the Trade, Health, and Environment Impact Project partners. s and be more cost-effective. 2.4.1 Deforestation. Less Negative Effects: Natural gas has fewer negative effects on human health and the environment. However, they are also responsible for contributing to some of the greatest environmental impacts. That impact has been largely positive over the last two decades, as greater use of natural gas and LNG have contributed to reduced carbon emissions and provided reliable support and back-up for renewable energy. Acidizing is less regulated than other methods and is believed to improve oil well life. Chemicals from flooded roads, subways, tunnels and parking lots can also make their way into waterways. According to Reuters, power plants that run on natural gas provide enough continuous electricity that it could potentially be used as a stop-gap for intermittent renewable sources like wind or solar power. When greenhouse gases release into the atmosphere these include carbon dioxide, methane, nitrous oxide, ozone, and water vapor and trap the sun's heat, they warm the average global temperature, causing it to rise. One of the primary advantages of gas turbines is that they produce relatively little pollution, at least compared with coal-fired power plants. Air quality decreases daily due to methane infusion into the atmosphere leading to nausea, sickness, and in extreme cases, death.
