Carbon dioxide is an significant contributor to the enhanced greenhouse effect. It can result in trapping more of the heat that Earth is radiating into space and cause detrimental climate changes and rising sea levels. The main concern regarding the combustion of organic compounds is the result of incomplete combustion. Incomplete combustion occurs when there is not enough oxygen to completely burn the fuel to carbon dioxide and water, causing pollution and fuel inefficiency. For example: Pentane reacts with little oxygen to form
Pollution from coal-fired power plants is released as fly ash, bottom ash and waste gases. Coal-fired power plants produce large quantities of sulfur dioxide and nitrogen oxides, the key pollutants in the formation of acid rain. Acid rain acidifies water bodies and harms forests and coastal ecosystems. Coal-fired power plant is the largest single source of atmospheric mercury emissions which is toxic to the developing brain, and exposure in the womb can cause health problems in children. Mercury released in the air gets into the waterways and is accumulated in fishes which are consumed by humans.
Waste and Energy Sandra Jenkins, William Matos, Tony Brown, Steve Olberding ENV/100 May 26, 2014 Jennifer Ott Waste and Energy Plastics and pesticides are both a type of waste. The former is considered a solid waste and the latter is a categorized as hazardous waste. Where do these wastes come from and what kind of effect do they have on the environment either when they are used or disposed of? Oil and natural gas are fossil fuels that emit their own waste once used. The effects of their use on the environment can be far reaching and detrimental to health of humans, animals, and other organisms that inhabit the earth.
Cutting down the amount of dangerous emissions from vehicles is one of the many benefits of electronic fuel injection engines. Other benefits include better control of power output for varying driving conditions, greater durability, and better fuel efficiency. The electronic fuel injection system replaced carburetors as the means of delivering fuel in precise amounts as the engine operates. There are different types of electronic fuel injectors found in automobiles and other vehicles, but it is the current mainstay for internal combustion engines. A carburetor mixes the fuel and air before the intake into the engine.
In the graph it showed the excess uses of sulfur dioxide and nitrogen oxide which are primary causes of acid rain. Transportation, electric utilities, fuel combustion, and industrial sources of sulfur, and nitrogen emissions can be lowered by limiting the amount of fossil fuels being used. Energy Alternatives like wind power, solar power will be helpful to the environment. Referring to the speaker Car pooling or using different energies available to power automobiles would be
The term Pollution is defined as the introduction of harmful pollutants into the land air and sea. Air Pollution however is the introduction of harmful contaminants such as dust fumes vapors and gases into the earth’s atmosphere. The earth’s atmosphere comprises of nitrogen (78%), oxygen (21%) and another (1%) making up the rest of atmospheric gases. Air pollution sources are both natural and manmade. Greenhouse gases are the main actors when it comes to the greenhouse effect.
We also can produce diesel and gasoline for our nation’s income. The fuels produced by the coal liquefaction can be used to power vehicles, heat homes and run factories and many more. There are two main stages in the coal liquefaction process. Coal gasification and gas to liquid (GTL). In the coal gasification process the air and stream are added to the raw coals then heat it to hundred degrees Fahrenheit.
One of the increasingly popular types of gasification is Plasma Gasification. Plasma gasification technology has been shown to be the most effective and environmentally friendly method for solid waste treatment and energy utilisation. It is a non-incineration thermal process that uses extremely high temperatures in a partial oxygen environment to decompose completely the input waste material into very simple molecules. The products of the process are a fuel or gas known as synthesis gas and an inert vitreous material known as slag (Stehlı´k, 2009). Plasma gasification uses an external heat source to gasify the waste, resulting in very little combustion.
The burning of fossil fuels has many negative effects on the earth. “Fossil fuels are hydrocarbons, primarily coal, fuel oil, or natural gas. They are formed from the remains of dead plants and animals” (RelightNY). The combustion of these fossil fuels releases large amounts of carbon dioxide into the atmosphere, daily. This contributes to global warming.
The natural causes include the release of greenhouse gasses such as methane (CH4). Man-made causes probably cause the most damage. One of the main ones in discussion is pollution. Pollution can be of many different forms for example burning fossil fuels. Fossil fuels are fuels made of organic matter such as oil or coal.
