Alternate energy
Alternate energy ââ¬â the solution to our depleting natural resources. A viable way to counter the effects of global warming. But is it really so? Every argument has its own pros and cons and we need to study both the sides before reaching on a hasty conclusion. As with all other discussions, the discussion centering around alternate energy sources has its own handful of proponents and opponents. Alternate energy sources are hailed the most due to their inexpensive and less polluting nature. Alternate energy sources are those which can be substituted for fossil fuels and include biofuels.Biofuels include among them vegetable oils, ethanol and methanol. As against fossil fuels, non renewable energy sources do not have a limited supply and hence their usage is not feared to bring about a rapid exhaustion of the resources. Careful studies of nonrenewable sources have made scientists to predict about possible exhaustion of these resources in coming century. The Federal Institute for Geosciences and Natural Resources puts an the lifetime of conventional oil to be only 32 years more, while its estimates about natural gas show that it will last 65 years more.This is one of the reasons that renewable resources are so much sought after now since the continuance of our work processes depending on these resources, is not threatened by their diminishing supply. Scientific studies have already revealed how the use of non renewable sources has proved to be hazardous to not just the environment but also the health of the population. This paper will discuss multiple sides of the issues of using these alternate energy sources. These issues are economic, ethical, social and environmental. We will discuss how the use of alternate energy sources will lead to less of global warming.In the environmental context, fossil fuels have been proven to be hazardous to nature and health. The environment is at great stake if we continue to use these fossil fuels. The combustion of fossil fuels leads to a number of pollutions ranging from water and land pollution to air pollution. It is held today that the highest amount of environmental pollution can be attributed to none other than the combustion of these fuels. The smog caused by the combustion of these fuels can not only cause human sickness but can also be dangerous to the sustainability of crops.Similarly, the release of carbon dioxide in environment form the burning of these fuels is a major cause of global warming. Many climate changes are a result of this global warming. Continued use of these fossil fuels will only aggravate the situation. The conversion of fossil fuels is another environmental problem as it results in solid waste accumulation. Another threat posed by fossil fuels is that of spill offs in seas and oceans during their delivery. This proves to be a menace to the marine life and very difficult to clean up. Biofuels in contrast do not have any such hazards attached to them.Burning biofuels rele ases carbon monoxide and sulphur dioxide in lesser quantities. A model by Argonne National Laboratory (ANL) shows that neat biodiesel form soya beans cut down the global warming pollution by more than 50% in comparison to conventional petroleum based diesel. Some other sources for biofuels such as algae have the potential of providing up to 90% reductions in global warming pollution. Biodiesel is also made form recycled food oil and waste products. Use of advanced technologies in future will see that the waste streams are being converted to diesel fuels.This will result in production of low carbon diesel. Biodiesel has got an edge over petroleum diesel fuel when it comes to low pollution emission. Biodiesel emit less of hydrocarbons as compared to conventional diesels and thus are environmentally safer. In environmental context then, biofuels seem to be a more viable option, by being less harmful and detrimental to environment and health. The issue of energy sources is such that now it has even got mixed with politics. In evaluating the viability of alternate energy sources, we also have to consider the political context relevant to the situation.Governments are now more than ever concerned about the dwindling supplies of fuels and hence are pushing for alternate energy sources. Before using an alternate energy source then, the political issues that need to be considered are many. One of the many aspects considered by a government before venturing into the development of any alternate energy source is the jobs and the growth provided by the fuels industry. The renewable industry is a newly developing one and has potential for growth in future. This is what the Canadian government has in mind and is one of the reasons why it is pursuing a greater use of renewable energy sources.Governments like Canada seek alternate energy source such as biofuels because they offer immense reductions in greenhouse gases (Susanne, 2007). They also provide an economical energy so urce for governments in the face of increasing petroleum prices. The basic reason however governments may consider alternate energy fuels such as these is the wish to support farming and rural communities. Hence, political issues such as consideration of population and growth and job opportunities in the alternate energy industry are some of the political aspects a government considers before opting for such a resource.The Canadian government has opted to go for biodiesels which shows that this form of energy is being sought after readily by governments and they think it as a feasible option to not only counteract the effects of global warming but also be beneficial in terms of providing job opportunities to the farmer population. If we consider the socio-economic aspect of this issue, we would see that alternate energy sources are being seen by governments as a lucrative option since governments have seen an increase in farm-products and thus that this could boost rural incomes (FA O, 2008).Hence, all the more reason to support the alternate energy source. Economically, the biofuels could prove to be fruitful for farmers in developed countries. The FAO report 2008 states that farmers of the developing countries could be supported and aided to reap the benefits of its production. If biofuels is produced in developing countries, not only will it be economically profitable for the local population but it will be a major cause for reduction in pollution. Todaro, in his book Economic development states that the most cumulative environmental degradation has been caused by the developed world.However, this trend is very much likely to reverse because of decreasing income patterns and high population growth rates in developing countries. Thus, providing the population of developing countries with a cheap substitute to fossil fuels will ensure lesser pollution created in the developing world. Keeping all these points in view, I opine that alternate energy sources are i ndeed the need of the day and promoting their use will reduce pollution and combat global warming. However, some contrasting views have also been found related to the use of biofuels.These present some problems in deciding whether to promote the use of biofuels or not. Producing biofuels requires more fossil fuel energy than is gained by the consumption of the fuel (Pimentel, 2001). Hence, it contributes to global warming and pollution too. On the political forefront, biofuels, particularly ethanol is being opposed against by the environmentalists on the grounds that promoting the use of biofuels might encourage farmers to abandon food crops and plant cash crops instead, which could then be used in producing fuel.Europe is one such region which has pursued in the past for policies favoring biofuels. However, the policy decision made in 2008, has met with strict criticism from lobbyists, citizens and environmentalists. Ethanol, one of the biofuels, then does not appear to have a stro ng foothold when it comes to political grounds. Policies to promote biofuels in regions such as Europe and U. S have met with censure and disapproval as it does not seem to be such a feasible source. Political and environmental arguments however are not the only ones to be considered.The social aspects have to be considered too. One may argue that producing biofuels will be good for society. More cash crops will be grown, with better return to society and less production of pollution. However, a study shows how the production of biofuels is actually a social tragedy for humans. To sum up, the report declares that producing biofuels is not a feasible option as it will only be disastrous for farmers, the environment, and citizens, particularly, the poor ones (Altieri & Bravo, 2007). The report gives example of U.S that how even the utilization of all soya bean and corn crops will not be enough to meet more than 12% of its gasolineââ¬â¢s needs and 6% of diesel needs. One-fifth of co rn harvest in U. S has already been dedicated to biofuels but this too could meet only 3% of its domestic energy demands. Is it then ethical to pursue this option when it seems to have a plethora of arguments opposing it? Apparently, there is a trade-off between the economic and environmental benefits to be reaped from the production of biofuels, against the social costs of getting the food crops being replaced by cash crops.Cheap fuel to source the industries of a country or food for feeding the population? These are the two precarious questions waiting to be answered. Through the course of the discussion of paper, we have seen how alternate energy source may prove one of the ways to combat pollution and be beneficial for the environment. However, to do so at the social cost of hungry population would be a crucial mistake. The key to this problem is maintaining a balance between the two. In the face of food crisis and rising food prices, priority should be set on solving the proble ms of food security.Developing countries, hence must not seek out so actively to promote the use of alternate energy source. Rather, their focus should be on getting the food crisis resolved. One of the FAOââ¬â¢s recommendations with regard to this aspect says that ââ¬Å"policies should be developed with appropriate international coordination to ensure that the international system supports environmental sustainability goals as well as social goals for agricultural development and poverty and hunger reductionâ⬠.Hence, to achieve the goals environmental sustainability, alternate energy source i. e. biodiesels must be sought keenly but only if the social costs of doing so are not greater than the economic profitability.

Wind and Solar Energy Essay Example | Topics and Well Written Essays - 250 words
Wind and Solar Energy - Essay Example Hence, they both need a storage mechanism to store the excess power obtained when the wind and the sun are available. Usually, the storage mechanism is a battery system, like the lithium-ion batteries. Nevertheless, differences exist between these two energy sources. Availability of the two power sources brings about a difference between them. The difference is that, solar power is only available during the day. On the other hand, wind power can be available throughout the day for as long as he wind is blowing. The methods of obtaining the two also differs in that; wind power is obtained mechanically with the aid of turbines while solar power is obtained through solar panels that convert sunlight to electricity. The differences and similarities given show that, renewable energy is feasible and it can be used to build green economies worldwide. It provides man with diverse means to obtain energy. The two renewable energy sources complement each other and can be used to provide energy in diverse weather

During this day, all Jains congregate in temples for devotions. a) New Year Festive- in nations like Sri Lanka and Thailand, the New Year is usually celebrated for about three days from the first full moon in the month of April. In other Mahayana countries, this celebration is held the first full moon of January. b) Vesak- Vesak is held to commemorate the birth and death of Buddha, the enlightened one. It is, thus, the most important event for the Buddhists. The celebrations usually happen during the first full moon of May. Other Buddhism festivals that remember the life of Buddha are the Magha Puja and Asalha Puja Day. a) Oshogatsu- this is the celebration of the closure of the old year and opening of the New Year. During the closure of the year, the people party as they symbolically wash away the misfortunes of the past. They also express their wishful expectations of the New Year. These festivals usually give the members of these religions the opportunity to come together as one family and share their spiritual experiences. Most worshipers usually get spiritual nourishment from these festivals. In Hinduism for instance, the festivals help them divert their attention from the worldly things and concentrate on the spiritual matters. In Shinto, the visiting of the graves helps them make peace with their ancestors and gods. It is during such times that the members of these religions decide to give to the poor in the society and preach peace. As they give back to the community by helping the poor, they create a harmony between the community and religion. During these celebrations, the people usually feast with food and drinks and the outsiders are always invited to take part. Diwali is a good example. Therefore, such celebrations bring the people together and help create peace in a social set

Understanding positive environment for student learning and Research Paper
Understanding positive environment for student learning and professional collaboration - Research Paper Example lsââ¬â¢ management towards creation of a positive environment but also helped in understanding the relationship between good instruction, assessment, and collaboration. The interviews with administrators, teachers, and parents helped in understanding the vision and concerns of these stakeholders regarding positive environments. At the end of the project, a walkthrough was also conducted the purpose of which was to get an insight into the importance of positive environment and collaboration for students and teachers respectively. In educational sector, the most important thing that matters for all stakeholders is a positive learning environment. The reason is that positive environment promotes enhanced learning and collaboration for students and teachers respectively. A positive learning environment is not restricted to any particular stakeholder, rather includes all stakeholders who have a specific role to play in improving instruction, collaboration, and assessment areas. Students need a positive environment to show improved performances not only in classrooms but also in the play grounds. Similarly, teachers need a positive environment where they can provide education to learners in interactive way using latest educational technologies and equipment. Along with students and teachers, the role of parents cannot be ignored by any means because parents are highly concerned about the environment in which they send their children to learn. Parents are one of the main stakeholders of any educational institute b ecause they are directly concerned with the schools performances of their children. Therefore, the role of teachers, students, and parents is equally important in moving towards the cause of creating a positive learning and collaboration environment at schools. A positive learning environment has some key characteristics that make it an essential element in the success of an educational institute. For example, a positive learning environment is one that reflects

Culture and Identity Literature review Example | Topics and Well Written Essays - 2750 words
Culture and Identity - Literature review Example To understand the significance of the representations of media and the culture is also the need to examine how culture and identity is defined and how this may be affected by media perceptions or conflicts. The question of how the media changed or portrayed culture through 7/7 events can then be understood by building a sense of how culture and identity fit into a given society. Defining Culture and Identity The concept of culture and identity is one that is based on perception and the way in which one interacts within society. Identity begins with an individual and how the one person understands their own realities, experiences and expressions. The personalities, behaviours and the association which one has with others become the main attributes of identity. The concept of creating labels at an individual level becomes the main component that is associated with personality and identity and changes the way that most associate with others. This begins with the psychological relationsh ip one has to the labels and the desire to be a specific identity. This mental decision then creates an attraction to specific groups and segments in society. It is the similarities that are a part of the individual and that create a relationship to others that creates the sense of culture, or belonging to a group that has the same identity (Postmes, Jetten, 12: 2006). As the concept of identity begins to form in groups, the culture is formed with specific behaviours and ideals. Physical, mental and behavioural similarities often relate to the group that has formed and which creates a culture. However, the similarity is that each individual believes there is a similarity within themselves that is reflected in the group, either physical or through behaviour. Acculturation and adaptation combine with this at a different psychological level to create a set of relationships that can work toward the same identity. For instance, religious changes, adapting to physical presence that is exp ressed by the group and associating with mannerisms are able to add into the reflection of the culture. The conceptualization of a culture from different perspectives creates the main changes that are a part of the group (Berry et al, 303: 2006). The process of building culture becomes associated with the basis of psychological relationships which are created and the defining of behaviours and interactions which are comfortable to various individuals. The reflection that is seen then becomes a part of a minority or majority group. If the comfort is from ethnicity or race, then defined behaviours are also known to associate with this. The relationship between the individual and a segment of society becomes important in defining the way in which the individual perceives their own identity and how this integrates into the building of various groups. When looking at the definition of culture, it can be seen that individual identities that find similarities integrate to create groups and segments within a given society. Communication and Culture The concept of culture and the way in which this is expressed becomes based on various levels of communication used among groups and to show identity. The communication is not only based on the language and basic affiliation with a culture. There are also purposes that are used behind the cultural connotations and

Kingdom of Life Essay Example for Free
Kingdom of Life Essay The Kingdom of Monera is the smallest in size in the biological world but are the most in terms of numbers. They can be found almost everywhere on earth. Monerans are the only kingdom of the prokaryotic type, organisms that lack a nucleus. The most common of this kind is the bacteria, which most people know are harmful for it causes illnesses and some degrees of food poisoning. The division of a single bacterium into two similar daughter cells constitutes the bacterial growth. This process is called binary fission which in turn promotes its population to grow exponentially. Bacteria are said to be the first inhabitants of Earth. Protozoa, fungus-like protists and the algae are the major categories under the kingdom of Protista. Members are categorized as colonial, unicellular or multi-cellular. Organisms under this kingdom are all eukaryotic, meaning they all have a true nucleus. Most undergo mitosis for their growth while some by meiosis and fertilization for their reproduction process. All organisms live in a water-based environment. Network forming which is called mycelia is the common process in which members of the kingdom of fungi grow. Fungi cause diseases in plant like smuts and rusts, while severe damage are from stem root and leaf rots. Most common in humans are athleteââ¬â¢s foot and ringworm among others. Animal diseases are very hard to treat because of its genetic and chemical similarity to fungi. Harmful as they may seem, some fungi members play significant roles in the ecological system. Some plants canââ¬â¢t grow without fungi. Breakthroughs in medicine are synthesized from fungi while others are used for food. The environment can not take form without plants. Humans canââ¬â¢t live without them. That is how important the kingdom of plantae is to our planet and to our lives. Said to lived 360 million years ago, plants vary in sizes, from very small kind to tall huge trees. Plants reproduce asexually and grow with the help of external factors. They are the only living organisms that are able to produce their own food through photosynthesis. Members of the kingdom Animalia are all heterotrophs. Animals, for their sustenance and survival, depends on other organisms around them. All organisms of the kingdom are eukaryotic and multicellular. Animals reproduce sexually through their special cells which when united form the zygotes that later grow into a new individual. The first recorded phyla of this kingdom was a marine specie some 542 million years ago. References: Windows Team, (1998, December 17).
