Context:
Ecologically clean fuels have an important role in people’s lives. Humanity realizes this significant importance and uses more and more “green” fuel nowadays. What does “green” fuel means? “Green” fuel is the source of energy that does not make harm on environment and made up of organic matter. This type of fuel can be derived from plants, domestic, industrial garbage and agricultural.
There are a lot of issues in Asia caused by air pollution. Pollution is caused by working of factoruies, car emissions, human activities. In one word, people are responsible for these problems. Greenhouse effect is the process where su nlight can move through Earth's atmosphere but can not move towards the sun. Greenhouse gases keep the Earth warm through this
For example, Law on the Prevention and Control of Air Pollution made by Chinese government. This low can decrease air pollution and incease producing of ecologically clean fuel or Biofuel. Biofuel has more advantages than dsadvantages:
Firstly, biofuels have the potential to be less expensive than petrol and other fossil fuels. This is particularly true as worldwide demand for oil increases, and more sources of biofuels become apparent.
Secondly, whereas oil is a limited resource that comes from specific materials, biofuels can be manufactured from a wide range of materials including crop waste, manure, and other byproducts. This makes it an efficient step in recycling.
Thirdly, it takes a long time for fossil fuels to be produced, but biofuels can be easily renewable as new crops are grown and waste material is collected.
Fourthly, biofuels can be produced locally, which decreases the nation's dependence upon foreign energy. By reducing dependence on foreign fuel sources, countries can protect the integrity of their energy resources and make them safe from outside
Yes, we hear it every day about the state-of-the-art eco-friendly cars or refrigerators, although what is not explicitly stated are the processes to create those green products. Parts and pieces will arrive at the assembly plant by car, train or plane, which are not always green and contribute to the CO2 emissions, which are damaging the ozone. The only way to be truly green is to not drive an eco-friendly car or to build one. I concur with Owens that going green could be deteriorating the environment in unforeseen ways and one way to correct this demeanor is to consume less. The increase in natural gas and its extraction has plummeted the price resulting in its overuse, which has diminished the interest in renewable energies.
Semantically fossil fuels are a renewable source of energy, however given that it takes millions of years for the organic materials to be broken down and converted, it is wholly unrealistic to consider them as renewable. As the demand for fossil fuels increases and source diminish faster than they are replentished, the United States must work towards a renewable energy independent state using truly renable sources, both technically and in practice. With changes in the home, as consumers in buying goods and with alternative fuel sources backed by public trust and governmental involvement, the United States could drastically lessen its dependence on fossil fuels, foreign and domestic.
In conclusion, the fact that biofuel is renewable unlike other natural resources such as coal, nuclear fuels, and petroleum makes it an excellent energy solution. However, there are still several major problems that need to be fixed before biofuel is recognized universally and used on an industrial scale.
Fossil fuels are very limited and they are used a lot. Fossil fuels are also very harmful to nature. Carbon emissions, that are produced from the use of fossil fuels, affects the globe
“All Biofuels Are Not Created Equal” is a very informative article that everyone should be aware of. The authors of this article show how biofuels can be made to benefit Earth. Our ecological footprint is so big that everyone requires 2.5 Earths to maintain the same lifestyle. What does this reveal? It reveals that Earth’s resources are being diminished. This means that the world needs to do something to prevent this so Earth can last for future generations. The way that biofuels are being made is not very effective in helping this problem. This is because it either requires deforestation or the burning of fossil fuels, which the world is trying to stop. Instead of using corn or sugar cane as ethanol, alternative crops should be used because it will benefit our environment the most.
Introduction:The idea of biofuels is a old concept, reaching as far as the ending of the 19th century. Solid in its idea but flawed in its presentation. Biofuels are a alternative energy to fossil fuels that are made from natural methods such as plants and crops and are key in solving the apparent flaws of fossil fuels. While fossil fuels have been in use for over a century, Biofuels have now risen to the popularity and been exposed to the press. At one point of time biofuel were being considered by some of the most brilliant minds ever in human history such as Henry Ford and Rudolph Diesel who believed that biofuels had the potential to be the new evolution s on only to reappear a century later. Now the world faces the struggles of global warming and the depletion of fossil fuels slowly dimming by day. Throughout the last century biofuels have proven to have a place in our society as a new alternative fuel source. Specializing in Being Natural and healthier than fossil fuels, biofuels have had a rough beginning against its competitor due to key situations such as pricing, Side effects, to fuel power. However the idea was passed on a to the later generations, and continued to pasand prolong usage. However through the last decade they have been highly advertised by politicians and Government officials claiming it to be the future of a powerful working society, and to help in making a new energy free world. Through belief Some even claiming that “By 2050, a new generation of sustainable biofuels could provide over a quarter of the world’s total transport fuel, according to a recent report by the International Energy Agency” (last name). With such improvement biofuels should be the obvious answer to providing a better future to th...
Secondly, the use of biofuels is not a cost effective option as they are more expensive than fossil fuels. According to the County Commissions of the US Department of Agriculture and North Dakota State University, there are around seven biodiesel producers in the US. Biodiesel is the mix of biofuel and diesel in 20:80 ratio, which means that the cost of biodiesel will be around 20$ more ...
...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.
Air pollution and greenhouse gases are the reason for the planet as it is today; the reason why we see campaigns flooding the media informing us to ‘switch off’, ‘save the planet’ and ‘turn down the heat’ and the reason why the government is trying to develop a successful scheme, such as the carbon tax scheme, to reduce air pollution caused by major industries. Air pollution and greenhouse gases are the two immediate causes of global warming and climate change. Air pollution occurs when chemicals or particulate matter enter the atmosphere. They can cause damage to living organisms on the planet, as well as destruction to the natural and synthetic environment (Energy Environment.net 2008). Greenhouse gases are gases in the atmosphere that absorb infrared radiation emitted from the earth. They trap infrared radiation in the form of heat, and hence contribute to global warming. Anthropogenic greenhouse gases are a direct result of air pollution. They are the physical gases emitted that cause air pollution. Naturally occurring greenhouse gases also have an influence on the earth’s atmosphere, though it is not as conspicuous as anthropogenic causes. Together, air pollution and greenhouse gases are intensifying climate change and global warming on a world-wide basis.
Air pollution is caused by many things such as car fumes, burning of fossil fuels,
Energy is a valuable source to people around the world and overtime we have become much dependent upon fossil fuels. Fossil fuels include coal, oil, and natural gas. Although these resources are abundant, they will not always be readily available to us. That is why we need to begin searching for other renewable resources that can create more energy. Biomass is a very important renewable resource and has the potential to be our gateway to a cleaner future.
The concept of this essay is to stress that biofuels are a viable and sustainable energy source than fossil fuels, showing its advantages but not ignoring its disadvantages which also enlightens us about the cleaner and renewable natural resources. Biofuels is an alternative source of energy which can end the global dependence on fossil fuels.
One of the most popular effect of air pollution in the world is global warming. With increased temperatures worldwide, the increase in sea levels causes melting of ice and this causes loss of habitat have already signalled a disaster if something for preservation or normalization is not done it will affect the world even more. Species that stay in the ice area, they will be in the verge of extinction. The Paris Agreement is an international treaty, under which all countries in the world have agreed to do their best to reduce gases that cause global warming. The following are the major effects of air pollution:
There is a lot more awareness of air pollution in the world today than any other as a lot of it is visible. Air pollution can be thought of any substance that people introduce into the atmosphere that has damaging effects on living things and the environment (National Geographic). Carbon dioxide released into the air breaking down the ozone layer slowly warming the earth, I’m sure you’ve heard this before but it’s the process known as global warming. These green house gases come from the fumes of cars, factories and peoples homes every second that passes. The activities of the people on earth have raised the temperature of the planet to higher than it has ever been in the last 150 years. (National
Fuels like coal, and oil that once were a fine innovation in creating energy are now rapidly deleting and one day will be gone forever; energy that won’t last is often referred to as non-renewable energy. Besides being set up to fail and become inefficient in the future, fossil fuel energy is not clean to use and poses several environmental complications. Coal, for instance is “the dirtiest of all fossil fuels. Coal combustion not only produces sulfur oxides and nitrogen oxides that contribute to acid rain and snow, it generates millions of tons of particulates that cause asthma and other respiratory diseases.” As with all usage of fossil fuels, it creates enormous amounts of carbon dioxide, which contributes to greenhouse gas. Not only are fossil fuels dirty, they also pose as a security risk and unforgiving on the American wallet. (Saini)
