Global Warming: Technical Solutions

Global Warming: Technical Solutions Evaluate the Technological Solutions Available to Ameliorate Global Warming Introduction Global warming has been proven to be the direct result of anthropogenic causes or man-made interventions with nature. Starting with the Industrial Revolution of the late 18th Century, technologies have been developed that resulted in the accumulation of greenhouse gases in the atmosphere which trap the sun’s radiant energy. This enhanced greenhouse effect gradually raises the earth’s surface temperatures and is projected to create irregular environmental conditions, namely: the melting of polar ice caps, rising of sea level, profound agricultural changes resulting from climate change, extinction of species, abnormal weather conditions, increased incidence of tropical diseases, disappearance of ecological niches and disruption of drinking water supply, (Global Warming, 2004). Since global warming offers a great potential to create catastrophic effects on the environment as a whole, it becomes a global issue, requiring the involvement of the whole international community in finding ways to ameliorate its adverse effects, (Baird, 2006). Global greenhouse gas emissions that are causing global warming come from different sectors. Figure I below shows the global greenhouse gas emissions by sector data: Land use change and forestry contribute the highest greenhouse gas emission rate (19%); followed by electricity (16%); agriculture (14%); transport (13%); other fuel combustion (11%); manufacturing and construction (10%); waste (4%); and industrial (3%) and combined heat and power (3%). The Pew Center on Global Climate Change (Undated, p. 1) asserts that â€Å"because there are so many sources of these gases, there are also many options for reducing emission.† This paper evaluates the available technological solutions to ameliorate global warming by presenting the advantages and disadvantages of each option. Moreover, such solutions will be presented on a sectoral basis, starting with land use, forestry and agriculture; followed by electricity, and finally by the transportation sector. Land Use, Forestry and Agriculture Sector Technology Land use and forestry technology includes carbon accounting, sequestration, and biofuel production. 1. Carbon Accounting and Sequestration According to the Intergovernmental Panel on Climate Change or IPCC (2000), carbon stock enhancement from land use, land –use change and forestry activities are reversible and therefore require careful accounting. Carbon accounting technology, which involves land-based accounting and activity based accounting, provides accurate and transparent data on carbon stocks and/or changes in greenhouse gas emissions by sources and removals by sink. These data are required to assess compliance with the commitments under the Kyoto Protocol. Moreover, carbon accounting will help determine relevant carbon pools that can be used in the production of an alternative source of fuel, such as biofuels. Changes in carbon stocks can be technically determined with the use of activity data, remote-sensing techniques, models derived from statistical analysis, flux measurement, soil sampling and ecological surveys. However, the cost of carbon accounting increases as precision and landscape heterogeneit y increases, (IPCC, 2000). As a result of careful carbon accounting, excess carbon can then be captured or sequestered in order to be utilized as fuel source. An example of carbon sequestration technology is the Integrated Gasification and Combined Cycle Process or IGCC, which allows for easy sequestration of carbon for long term storage in underground geological formations. However, the Pew Center on Global Climate Change (Undated), cautions that further research is needed to test the viability of large scale underground storage of carbon in a long term scale. 2. Biofuel Technology Biofuel production or biomass gasification ensures lower greenhouse gas emission levels by converting waste wood and biomass into biofuels that could replace fossil fuels. The report of the Pew Center on Global Climate Change (Undated, p. 4), maintains that agricultural lands can be planted with carbon-dioxide fixing trees that can be used for fuel production. This will result to land use changes that may have multiple indirect benefits such as improvement of soil, air and water quality; and increase in wildlife habitat. However, study findings suggest that the cultivation of corn and soybeans for biofuel production produces adverse environmental impacts, such as the leaching of pesticides and nitrogen and phosphorus from fertilizers into water resources, (Manuel, 2007). Moreover, biofuels are from two to four times more expensive than fossil fuels and are not believed to compete well in the marketplace. For example, â€Å"a fuel –cost comparison indicates that while gasoline could be refined for 15 to 16 cents per liter (in the late 1980s), the cost of biofuels ranged from an average of about 30 cents per liter (for methanol derived from biomass) to 63 cents per liter (for ethanol derived from beets in the United Kingdom)†, (Barbier et al. 1991, p. 142; cited in Johansen, 2002, p. 266). Electricity Sector Technology According to the Pew Center on Global Climate Change Report (Undated), power plants and coal combustion that supply electric power account for the greenhouse gas emissions on the electricity sector. Technological solutions available for this sector to address global warming include: 1. Integrated Gasification and Combined Cycle Process The Integrated Gasification and Combined Cycle Process or IGCC, is a power generation technology that improves the efficiency of electric power and heat generation with the use of a combination of fossil fuels and renewable energy. It enables clean gas production and the reduction in carbon dioxide emissions with the use of high performance gas turbines, (Abela, et al., 2007). Moreover, air pollutants such as particulate matter, sulphur, nitrogen and mercury are removed from the gasified coal before combustion, (Abela, et al., 2007). However, the major disadvantage of using this technology is its high cost of operation, which is about 20% more than the operating cost of a traditional coal plant, (Wikipedia, undated). 2. Renewable Energy Sources Renewable energy sources such as the wind, solar and water can produce electricity without releasing greenhouse gases and are thus important in the amelioration of global warming. a. Wind Power Wind power technology harnesses the power of the wind which is an indirect form of solar power, to supply energy. Some have propeller type devices, while others have vertical axis designs, which possess the ability to accept wind from any direction. According to Elliott (2003), wind power is already an essential source of energy; and that in 2002, the total generating capacity has reached 24,000 megawatts, with costs decreasing significantly with technology development. However, this technology often has large space requirements, due to the need of the wind turbines to be grouped together in wind farms, in order to facilitate sharing of connections to the power grid. Moreover, there should be a separation of about 5 to 15 blade diameters between individual wind turbines, in order to â€Å"prevent turbulent interactions in wind farm arrays† , (Elliott, 2003, p. 135). b. Solar Power Radiant energy can be captured and utilized to generate electricity which may be used to operate solar batteries or may be transmitted along normal transmission lines. Radiant energy is collected in a photovoltaic cell, which is a bimetallic unit that allows direct conversion of sunlight to electricity. The only drawback of utilizing photovoltaic cells is its high cost. However, recent â€Å"developments in the semiconductor industry have significantly brought down prices†, (Elliott, 2003, p.132). Electric power generation has also been accomplished with the use of big solar heat-concentrating mirrors and parabolic troughs and dishes that track the sun across the sky and focus its rays so as to raise steam, (Elliott, 2003, p130), and consequently produce electricity. One major disadvantage of using solar power technology is that it works only during the day and requires electrical storage mechanisms at night. Additionally, radiant heat is insufficient in cold regions and in ar eas with extensive cloudy periods, resulting in low amount of energy collection. c. Water Power Hydropower is the world’s biggest renewable source of energy. It is deemed as one of the most acceptable and cleanest technologies whereby a unit of water produces hydropower cumulatively by passing through the turbines of many dams along the descent of a river†, (Gibbons, 1986, p. 86). According to Elliott (2003, p. 151), â€Å"there is around 650 GW of installed capacity in place, mostly in 300 large projects. However, in recent years, there have been social and environmental concerns about large hydros, and some new projects have met with opposition†. Its adverse environmental impacts include the destruction of large areas of natural vegetation and agricultural land for water storage; biodiversity loss, flooding and displacement of population, (Elliott, 2003). 3. Geothermal Power Geothermal power is not considered a renewable resource when used at rates of extraction greater than their natural replenishment. With sustainable use, however, geothermal power can be effectively harnessed to provide electricity. Geothermal energy comes from the heat of the earth and can be categorized into geopressured, magma, hydrothermal and hot dry rock, (Wright, 2002, p. 362). According to Hobbs (1995, cited in Wright, 2002, p. 362), commercial operations are mostly in the form of hydrothermal systems â€Å"where wells are about 2000 metres deep with reservoir temperatures of 180 to 270 °C.† Although geothermal systems produce less than 0.2 percent of the carbon dioxide produced by coal or oil-fired plant, they also emit non-condensable gases such as small quantities of sulphur dioxide, methane, hydrogen sulphide, nitrogen and hydrogen. Additionally, such systems cause induced seismicity and ground subsidence. They are also capital-intensive investments that require f inancial and technical assistance, (Wright, 2002, p. 362). Transport System Technology The transportation sector has one of the highest greenhouse gas emissions rate, after land use and forestry, electricity and agriculture sectors. The Pew Center on Global Climate Change (Undated), recommends the use of â€Å"off the shell† technologies that are currently available in the market, which significantly reduce greenhouse gas emissions of conventional cars and trucks. These â€Å"off the shell† technologies focus on increasing energy efficiency, fuel blending and the use of advanced diesels and hybrids. Additionally, long term technological options to reduce greenhouse gas emissions are now gradually being developed which include the use of biofuels, electric vehicles and hydrogen fuel cells. a. Fuel Blending Fuel blending involves the mixing of ethanol and other biofuels with gasoline to produce more-environment friendly fuels. The Pew Center on Global Climate Change (Undated, p. 4), asserts that corn-based ethanol can reduce greenhouse emissions to at least 30% â€Å"for each gallon of regular gasoline that it replaces†. b. Diesels and Hybrids Diesel and hybrid engines offer excellent fuel economy and overall fuel efficiency. However, they also emit air pollutants such as nitrogen oxides and particulates. Newer diesel engine models, however, use very sophisticated fuel-injection systems, which result in vehicles that have better acceleration with reduced emissions, vibration, and noise†, (Doyle, 2000, p. 383). Moreover, because diesels and hybrids afford excellent fuel economy, they use less gas on a per mile basis, thereby producing less greenhouse gas emissions compared to conventional cars and trucks. â€Å"When both technologies are combined in a diesel hybrid vehicle, it can yield a 65-percent reduction in greenhouse gas emissions per mile†, (Green and Schafer, 2003; cited in The Pew Center on Global Climate Change Undated, p.6). c. Biofuels As previously mentioned, biofuels offer cleaner emissions than regular gasoline. Agricultural and forest products can be processed to produce ethanol that may be combined with gasoline and enable significant reductions in greenhouse gas emissions. Corn-based, cellulosic and sugar-cane-based ethanols have been proven to significantly reduce emissions, (The Pew Center on Global Climate Change, Undated). d. Electric Vehicles Electric vehicles offer cleaner emissions by reducing the amount of pollutant and greenhouse gas release in the air. They release â€Å"30 percent less hydrocarbons and 15 percent less nitrogen oxides† than conventional vehicles, (Doyle, 2000, p. 289). In the past, electric cars needed advances in battery storage. Thus, the â€Å"plug-in† hybrid was developed in order to solve the battery storage problem. The â€Å"plug-in† hybrid â€Å"is a gas- electric vehicle that can be charged at home overnight†, (The Pew Center on Global Climate Change, Undated). e. Hydrogen Fuel Cells Hydrogen fuel cells â€Å"produce power by combining oxygen with hydrogen to create water†, (The Pew Center on Global Climate Change, Undated, p.6). Hydrogen is obtained from natural gas by reforming and is combined with oxygen that is readily available in the air, which generates electricity continuously. The fuel cells replace combustion turbines in integrated cycles, resulting in increased fuel efficiency of 46-55 percent. However, there is a need to find ways to produce hydrogen with minimal emissions, (The Pew Center on Global Climate Change, Undated). Conclusion A careful analysis of the global greenhouse gas emissions by sector is essential in identifying the needed technological solutions to help curb or reduce gas emissions. By focusing the effort to reduce emissions of the higher contributing sectors, the overall efforts to address global warming effects can be effectively channeled. Thus, it is imperative to focus on the available technologies that address the adverse effects of global warming on the following sectors: land use and forestry, electricity, agriculture and transport. In its comprehensive report on technological solutions for climate change amelioration, the Pew Center on Global Climate Change (Undated, p.2), claims that â€Å"there is no single, silver bullet technology that will deliver the reductions in emissions that are needed to protect the climate†. It further recommends the integration of a portfolio of solutions wherein the identification of useful technologies should be based on the analysis of key economic sectors. Moreover, it suggests that policy makers should prioritize the creation of incentives that will release the power of the marketplace in developing solutions. In the final analysis, further research and development of more exact and cost-effective portfolio of technologies that ameliorate global warming effects must be advocated.

Oligopoly versus monopoly competition Essay

Differences Between Oligopoly and Monopolistic Competition Market Structures Market structure refers to the interconnected characteristics of a market, which include the number of firms, level and forms of competition and extent of product differentiation (Business Dictionary, 2012). Based on these parameters, several market structures are defined and this essay will focus on two of them, namely monopolistic competition and oligopolistic markets, by discussing the differences among them and their impact on the customers. Oligopolistic market is defined as a market that is dominated by few large firms, and that these firms are mutually dependent, where they have to monitor the actions of other competitors closely and act accordingly in response to that (Ison and Wall, 2007). These firms target bigger markets, at regional, national and even international level. Examples of oligopolistic markets include airline, petroleum and bank industries (Economics Online, 2012). On the other hand, monopolistic competition market refers to a market with large number of firms, each producing slightly different product, i. e. their products are unique in its own right and hence the firms have a certain degree of monopoly power (Ison and Wall, 2007). In general, these firms target a smaller market size, say at a local or regional level (Economics Online, 2012). For example, restaurants, hair saloons and boutiques are all examples under this market structure. Firms in oligopoly market have a certain degree of control over the price of their products (Ison and Wall, 2007). However, there is interdependence in price making between the firms. For non-collusive oligopoly, any price making decision will have to take into account the likely reaction of the other firms to ensure market share (Economics Online, 2012). Hence, there is a potential for price war, where the firms try to beat each other by lowering the price, without any increase in demand for their products, as illustrated by the Kinked Demand Curve (Figure 1; Economics Help, 2012). Such circumstance is undesirable as their profits might be diminished and the consumers will be the only beneficiaries. In contrast, in the case of collusive oligopoly, the firms collude among themselves by agreeing on a price of products to avoid price war. Owing to the significant market share they own, they can set the price high to gain supernormal profit (Geoff Riley, 2006). Figure 1. Kinked demand curve (Economics Help, 2012). In monopolistic competition, the firms have only little control over the price (Ison and Wall, 2007). This is because the extensive differentiation of products means the firms face constant competition from others, and may easily be replaced if their price is deemed unreasonable, despite certain unique features of their products. Oligopoly and monopolistic competition market structures also differ in term of profit making. Firms in oligopolistic can make supernormal profit all the time and there are several reasons to this (Ison and Wall, 2007; Amos Web, 2012). Firstly, they own significant market share in a huge market, therefore the sales volume is high. Secondly, average cost of production is low as they produce in bulk. Thirdly, as discussed before, they have the ability to set price, especially in the case of collusive oligopoly (Amos Web, 2012). For instance, Tesco is a chain supermarket that is found everywhere in the UK (hence huge market size) and as they purchase their products from suppliers in bulk, the cost is kept at minimum, thereby maximising their profits (Mearday, 2009). In contrast, for monopolistic competition, profit making is not for sure. However, theoretically speaking, there are two stages to the profit making by firms in monopolistic competition (Ison and Wall, 2012; Bized, 2001). In short run, the firms can set the price high to obtain supernormal profit (represented by shaded region in Figure 2A). As the abnormal profit they make in short run attracts many potential rivals, the firms must then set the price low to stay competitive in long run (Figure 2B). For example, in Canada, the price of personal computers was very expensive when they were first introduced into the market, but as the number of computer manufacturers increased, the price of personal computers has been declining over the past decade (Figure 3; Statistics Canada, 2011). B B A A Cost Cost Price Price Figure 2. (A) Profit maximisation in short run in monopolistic competition. (B) Normal profit making in long run in monopolistic competition (Bized, 2001). Figure 3. Change of computer price by different purchasers. (Statistics Canada, 2011). Mode of competition is also different between the firms in oligopoly and monopolistic competition. Oligopoly is characterized by imperfect competition, mainly due to high barriers for entry to market (Economics Online, 2012). This is due to various reasons including exclusive resources ownership, extensive relevant knowledge, patent and copyright, other government restrictions, managerial challenge and high start-up cost. (Economics Online, 2012; Amos Web, 2012). Airline industry is a typical example of that, as setting up an airline companies requires huge financial resource and compliance to strict rules and regulations imposed by the authority (Amos Web, 2012). For example, in Malaysia, the second airline, AirAsia was only established in 2001 (AirAsia, 2012), 46 years after the establishment of Malaysia Airline in 1947 (Malaysia Airline, 2012). In contrast, there is near perfect competition in monopolistic competition market, as there is freedom to enter or exit the market due to low entry barrier (Economic Online, 2012; Amos Web, 2012). As opposed to oligopolistic market, the start up cost for firms in monopolistic competition market is much lower, as the market size they target is smaller (Ison and Wall, 2007; Economic Online, 2012). Also, as discussed before, product differentiation in this market means each firm has a somewhat unique product, fulfilling the demand of a certain group of consumers in the market. Moreover, there is less restriction from the government and starting firm does not require exclusive knowledge. For example, one can easily open a restaurant, as long as he or she has a unique menu to offer. In conclusion, oligopoly and monopolistic competition represents two distinct market structures. From consumers’ point of view, monopolistic competition is more preferable. Through monopolistic competition among the firms, consumers enjoy to choose from a wider range of products, which are available at more competitive prices. This is because the firms always try to enhance their products with better innovation and keep their prices down to attract customers. Oligopoly on the other hand is less desirable for consumers as products can often be overly-priced since the firms have a greater control over price. References: 1.

History of Islam

Islam is the religion of the Arabic and Iranian world of which Hazrat Muhammad (P.B.U.H) was the prophet. He lived from 570A.D to 632A.D.The word Islam is derived from ‘silm’ which means peace, obedience and submission. It signifies submission to the will of God. Islam is one of the few great and wide-spread religions of the world. The adherents of Islam are called as Muslims.Islam came later than the other great monotheistic religions, like Judaism and Christianity. It drew its inspiration mainly from Judaism and Nestorianism. Muhammad (P.B.U.H) accepted the inspiration of the Old Testament and claimed to be a successor to Moses, and although he did no recognize Jesus as God, he did recognize Him as a prophet sent by God to guide the humanity on the path of spirituality.The sacred book of Islam is called as Quran. This book is written in Arabic and Muslims memorize the whole or part of it. Like Orthodox Judaism Islam is a literal-minded religion lived in everyday life. No Muslim is in any doubt as to exactly how he should carry on in the events of his day.Muhammad’s (P.BU.H) main achievements were the destruction of idolatry, the welding of warring tribes into one community, the progress of a conquest which led after his death to the great and cultured empire which spread throughout the Middle East into North Africa, north India, and ultimately to Spain. That it did not spread all over Europe was due to the Muslim defeat by Charles Martel at Tours in 732.After the death of Hazrat Muhammad (P.B.U.H) the reigns of govt come into the hands of his successors called as ‘Khalifas†. The first four caliphs are declared as the pious caliphs or ‘Khulfa-e-Rashideen’. The first one among them was Abu Bakr Siddique (R.A). He remained khalifa of Muslims from 632A.D to 634A.D. He on his taking the charge of govt in his own hands fought wars of apostasy (the Battle of Yamama 633A.D).These wars were fought against people who declare themselves as prophets and those who refuse to pay ‘Zakat’. The next in line were Umar (Aug 634-Nov 644), Usman (644-656A.D) and Ali(656-661A.D). These four rulers were selected to govern by four different selection processes. They established a system of government which is monarchical and ruled a vast empire according to the rules and regulations set by Hazrat Muhammad (P.B.U.H) and the holy Quran.During the reign of these four caliphs the Islamic state extended its borders extensively. Slowly this system of Government degenerated into a worldly empire which becomes power-hungry and corrupted. Though, physically the Islamic empire was spreading vast but politically there were many fissures in it. That corrupted it a lot.After the death of Umar, Usman succeed the throne but he was accused of favoritism and nepotism. He was murdered and succeeded by Ali. But the Muslims had been divided by then into groups and factions that were at daggers drawn towards each other beca use of political and ideological differences and a civil war(657-659A.D) started between them that was also declared as the ‘first Fitna’ in Islam.The civil war was fought between Ali on one side and Amir Muawiyah on the other. In reality the jealousy and rivalry between the two tribes, banu Hashim (the tribe to which Hazrat Muhammad P.B.U.H and Ali belongs) and banu Ummayah (the tribe of Usman, Abu Safiyan and Muawiyah), had been going on for the long time even before the birth of Hazrat Muhammad (P.B.U.H).‘The battle of Camel’ between Ali and Muawiyah remained indecisive and Ali was murdered by a Hwariji. After his death Muawiyah succeeded the throne (661-680A.D). Thus lay down the foundation of the hereditary Umayyad caliphate.Amir Muawiyah extends further the boundaries of Muslim state with the help of an able Muslim general Uqba bin Nafi. When he nominated his son Yazid (680-683A.D) as his successor he gave birth to the second Fitna (683-685A.D) in Isl amic empire. Imam Hussain, the grandson of Hazrat Muhammad (P.B.U.H) also laid claim on the ruler ship of the Islamic empire. His revolt failed to succeed and the clan of banu Ummayah ruled for another seventy years.During their reign Muslim world extended to North Africa and Central Asia as well as to many other places. There economic position improved greatly. There religion got recognition all over the world as Muslims spread themselves in far and wide of the globe. This new empire was tolerant towards the religious freedom of its non-Muslim subjects though a tax called ‘jizyah’ was imposed on them. With the introduction of non-Arab Muslims into the Islamic empire the tension grew within the state.

The Low Sense Of Self Esteem - 1548 Words

Starting as children, people are inclined to strive to be socially accepted. With social standards being very difficult to fit into, many people feel as though they do not belong to a set group of people; therefore, they tend to have a lower self esteem which causes them to act out. Being isolated causes one to feel a lack of confidence within themselves because him or her can feel as though they are not wanted and do not belong. This low sense of self esteem affects a person’s motivation and mental health. Social norms can cause people to feel alone and as though they have no one there for them. On the other hand, belonging to a community or a specific group can allow people to feel as though they have a support system, making them feel more confident in themselves and becoming better in their overall life. Feeling accepted and supported by people can increase intellectual activity and boost a person’s self esteem tremendously. Belonging and acceptance increase and dec rease self esteem thus dictating a person’s behavior. Being a part of a community is nearly essential in the process of becoming an adult because during the teenage years people are constantly shaped into who they will be for the rest of their lives. Throughout my kid and teenage years, I have always been a part of a dance team mixed with people my age, and younger or older.
