Renewable Energy in Canada Essay Example | Topics and Well Written Essays - 1000 words
Renewable Energy in Canada - Essay Example The second largest renewable source is wind that generates 1.6 percent of Canadian electricity. The third largest source is biomass with 1.4 percent share. Moreover, wind and photovoltaic energies are rapidly growing renewable sources in Canada. This paper briefly explores renewable energy and its contributions in Canada (NRCAN). Renewable energy is a kind of energy obtained from natural resources which can be renewed and regained within human lifespan, for instance, moving wind and sunshine. Numerous technologies and equipment are developed in order to exploit the potential natural resources. These equipments produce energy in the form of electricity, thermal energy, industrial heat, and transportation fuels (NRCAN). Canada's leading energy (renewable and other) resource is hydroelectric power. Most of this power is generated in water-rich and less populated Northern Canada in order to provide for urbanized South, for instance, Quebec's export to the U.S. Rapidly growing form of ren ewable energies are wind , solar, geothermal, and biomass. In 2009, Canada's generating capacity was 125,485 MW with 60 percent generated from renewable resources. Hydro power generation meets 90 percent of electricity demand in British Columbia and Quebec. However, British Columbia is a net importer while Quebec is a net exporter. Oil and natural gas resources are plentiful in Alberta and Saskatchewan, and Manitoba and Northern Ontario is rich in coal. On a national level, 20 percent generation is from nuclear source, 15 percent coal, and 5 percent is from natural gas source. Wind and solar energy are also gaining popularity through feed-in tariff (FIT). Enacted in 2009, FIT forced Ontario to trailing in North American market activity.FIT is supported by investor due to the money that flows upfront into the project (Wagman, 2011). It is estimated that Canada's generating capacity of 19,000 MW will retire by 2050.In addition, 45,000 MW generating capacity is required to meet the exi sting growth projects. Federal government's goal is to generate 90 percent of Canada's energy through non-emitting resources by the year 2020(Wagman, 2011). Ontario Power Authority (OPA) has signed 40 large-scale renewable energy projects under the province FIT program. These new projects include, solar, water, and wind projects which are expected to attract $3.04 billion in private sector investment. It will generate over 872MW renewable power, of which, 357MW is from 35 solar projects, 500KM from water project, and 615MW from four wind projects. It is claimed that these projects will produce 240 wind turbines and one million solar panels in Ontario. Canada's wind capacity is 3,549MW in 2011, and Ontario is the leading provider with1, 248MW or one third of the total wind energy production. Moreover, another one third is generated by Quebec (663MW) and Alberta (656 MW). Seven other provinces generate the final one-third of total energy. According to CanWEA, there is tenfold increase in wind energy production over the last six years (Wagman, 2011). Another comparatively untapped renewable technology is geothermal energy. Canada shares the same continental shelf and geology as Latin America, Mexico, and United States, and has other undeveloped 200 hot springs. However, federal government and provinces have failed to implement policies and regulations for further development of geothermal energy (Wagman, 2011). According to

America Today Essay Example | Topics and Well Written Essays - 750 words
America Today - Essay Example Just as before the first round of financial depression, America had just elected a charismatic leader to the White House who promised to fix the problems left by his predecessor. However, he failed to do so and the American people were left to pay the price . I find it quite disturbing that America seems to have a pattern of allowing history to repeat itself. As one will recall from our lessons in this class, America was enjoying one of its longest and largest economic growth spurts before the depression came along. This is a typical scenario that was again played out before the 21st century era of American depression, only this time, both the stock market and banking system collapsed. With more than 15 million Americans out of work, the government chose to pull the country out of the depression era by introducing European style social and economic reforms The New Deal allowed the government to have a more direct hand in the social and economic business of the American people. By adopting a policy of moderate currency inflation the federal government managed to jumpstart the economy and offer relief to some debtors by creating credit facilities that dealt with industry and agriculture. Banks were severely monitored and controlled so that they would not make the mistake of increasing their already existing bad loans. While The New Deal ushered in a new era of social, political, and economic stability for the government, the events happening overseas in Europe and Asia were slowly beginning to rear its ugly head in relation to the existence of America as a pacifist country. The American economy was at its peak when it became directly involved in the European and Asi an wars of World War II. Although the United States of America managed to survive the economic effects of the war through the act of selling bonds, rationing, and other cost saving measures at home, the country was slowly emerging as the de-facto leader in terms of international relations. The defeat of Hitler during the European War by the Allied Forces allowed their scientists to come and work for the Americans who were still dealing with the war in the Asia Pacific at the time. Since the nuclear bombs were actually a Nazi brain child, these scientists who worked on the project simply handed over their research, results, and expertise to their new masters, who in this case, turned out to be the Americans. We helped them fine tune the weapon of mass destruction without really having a real reason to use it in the Asia Pacific war. 3 There is a historical belief that Japan was actually close to surrendering and had already lost the war by the time the U.S. forces had decided to drop the bomb on Hiroshima and Nagasaki. A decision that the government made, according to historical documents, on the fact that by being the first to use a nuclear weapon, the United States will have the upper hand in the nuclear arms race and shall therefore be

Restatement problem definition technique
Restatement problem definition technique Task 1 The purpose of the task is to choose one of the scenarios and to apply the Present state/Desired state, Duncker Diagram and Statement/Restatement problem definition technique. The scenario 1 is about the problem associated with the recycling of post-consumer waste. It has been observed that even in the most cooperative and environment conscious communities, bins of recyclable waste contains 10% of wrong recyclable or non-recyclable material. For disposing non-recyclable material present in recyclable bins, recycling company has to spend lot of money. The problem needs investigation from the recycling company CEOs point of view. Summary of additional information gathered Generation of waste is strongly associated to population and urbanization [1]. Improvement of existing waste management technique is a prime concern for developing countries. In past, the most inexpensive practice for disposing waste was to place it in landfills. Despite the fact that the landfills were used to manage the waste, the need for restitution of the landfills, release of toxic gases, limited accessibility of the land for the landfills etc., still remains a great challenges for metropolitan cities. The ever increasing post-consumer waste has many adverse effects on the health of people, such as pollution of underground water and soil, bad smell from landfills and release of green house gases like CO2 and CH4 [1]. The concept of 3Rs which says reduce, reuse and recycle has become a key notion for waste management. The finest way to manage waste is not to create it. Generation of waste should be minimized at household level by avoiding excess use of non-environmental friendly goods. Recycling is the also one of the best option for waste management as it offers several advantages like utilization of waste which would otherwise be dumped in landfills and also decrease in use of new resources [2]. Novel methods of sorting non-recyclable waste from recyclable should be brought in use. The production capacity of paper in Malaysia has reached up to 1,300,000 T/year [3] but it is still low as compared to the consumption of paper there. Paper mills in Malaysia are now relying on machines which can sort different grades of paper. After sorting, high quality paper can be recycled. Malaysian paper mills are saving lot of money, energy, reducing the amount of landfills, reducing incineration and above all conserving their natural resources [3]. Shutting down of Freshkills Landfills in Staten Island in 2001 has strained the city of New York to find other methods of waste management. To dispose huge amount of waste, New York City is exporting parts of its waste to Virginia and its neighboring state. Remarkable increase in disposal tipping fees in recent years has forced New York City to find other methods for waste management. Recycling provides a striking alternative as it helps in decreasing pollution, providing employments and preserving energy. Municipal Corporation in New York City is now relying on materials recovery facility (MRF). MRF collects waste, segregates wrong or non recyclable waste from recyclable waste, recycle the waste and stores it as raw material for manufacturing industry. By doing this, City of New York is saving nearly $46 million per year from the total amount it spends today for waste disposal [4]. Present state/Desired State Technique Discussion: The present state talks about the presence of wrong or non-recyclable material whereas desired state talks about maximizing companys profit by proper separation and disposal of non-recyclable waste. There is no match between the present state and the desired state. Further reworking of statements is required. Discussion: These states are matched, but there is no clear difference between the present and the desired state. Desired state somewhat solves the issue in present state i.e. company has to spend money for disposing non-recyclable waste. Actual problem is not resolved yet therefore further reworking of solution is required. Discussion There is perfect one to one mapping between present and desired state. The problem addressed in present state is completely resolved in desired state. The desired state focuses on attaining zero percent contamination in recyclable bins. Therefore, if there is no non-recyclable or wrong recyclable material in recyclable bin there is no point in disposing it and there is no cost for disposing it. These statements can therefore be considered as the best statements for actual problem. Duncker Diagram Statement-Restatement Technique Original problem statement: Bins of recyclable material contain 10% of wrong or non-recyclable material and recycling company has to spend money for its disposal. Trigger 1: Emphasizing on different words and phrases Bins of recyclable material contain 10% of wrong or non-recyclable material and recycling company has to spend money for its disposal. Is there any other way to collect waste? Bins of recyclable material contain 10% of wrong or non-recyclable material and recycling company has to spend money for its disposal. How can we reduce percentage of wrong or non-recyclable material? Bins of recyclable material contain 10% of wrong or non-recyclable material and recycling company has to spend money for its disposal. Can we make use of these wrong or non-recyclable materials? -Some materials like used polythene bags can be reused as trash bags in houses for trash cans. In this way consumer can reduce the use of non-recyclable material. Bins of recyclable material contain 10% of wrong or non-recyclable material and recycling company has to spend money for its disposal. How can we reduce cost for disposing non-recyclable waste? Trigger 2: Substituting the explicit definition Containers of reusable materials are contaminated with non-reusable materials that are in fact, expensive to dump. Trigger 3: Making opposite sentence How to make bins of recyclable material contamination free, thus company has to spend no money for its disposal? Trigger 4: Use relaxing constraints Bins of recyclable material are never contaminated and there is no cost for its disposal. This technique helps us to think in different way. It motivates to develop a method so that recycle bins never get any contamination. Trigger 5: Replacing persuasive words The problem statement implies that we obviously want zero contamination of recyclable waste so that company has to spend no money for its disposal. Thus, if we could avoid contamination at source by marking the bins and classifying non-recyclable and recyclable waste for consumers. Trigger 6: Expressing words in the form of equation This statement can be expressed in equation form: Contamination in recyclable bin is directly proportional to presence of non-recyclable material. Therefore, By replacing, proportionality sign (with proportionality constant (k). This trigger helps us in thinking in alternative way. What factors affect the value of k? How can we minimize the presence of non-recyclable material? Proper tagging of bins, classification of non-recyclable materials and recyclable materials for consumers, reducing use of non-recyclable material etc. can help in reducing contamination of recycle bins.

Causes Of World War I 3 :: essays research papers
There were many immediate and underlying or fundamental causes of World War I. The difference between an underlying and immediate cause is that an underlying cause develops over a long period of time and indirectly leads to a specific event, and an immediate cause is a specific short-term event that directly leads to another event or series of events. While the immediate cause of World War I was the assassination of Francis Ferdinand, the archduke of Austria, by a Serbian member of the Black Hand secret society, there were various basic causes of the war. Three of them were nationalism, alliances between European powers, and militarism. Nationalism is a devotion and loyalty to one’s own nation, with primary emphasis on furthering its interests as opposed to those of other countries. This feeling widely spread throughout Europe during the 19th and 10th centuries and caused many problems. The Slavic people of Bosnia and Herzegovina wanted to break away from Austria-Hungary and unify with other Slavic nations. Russia as a Slavic nation backed up the two countries in this matter, therefore causing tensions between Austria-Hungary and itself. Nationalism was also a source of anger between France and Germany as France resented its defeat in the Franco-Prussian War (1870-1871). Alliances between European nations can also be considered an underlying cause of World War I. As a result of the Triple Alliance consisting of Germany, Austria-Hungary, and Italy, the Triple Entente (understanding) was formed between France, Britain, and Russia. Although France and Britain were natural enemies, their fear of Germany united them together with Russia. These alliances set the final stage for the beginning of World War I. Each country in each alliance would help each other during warfare. For example, if Germany attacked France, Britain and Russia would help France, and Italy and Austria would help Germany, dragging Europe into a state of chaos and violence. Militarism was also an underlying cause of World War I. As the alliance system divided Europe into opposing groups, each nation began to increase spending on its military. This set a belligerent mood in Europe as each nation was prepared to fight a war. A German officer once said "in time of peace, prepare for war," and that is exactly what European nations did, eventually leading to the Great War. Without a doubt, the one underlying cause of the three described above that was most responsible for World War I was the system of alliances.

Mobile Database Systems
Due to the increasing utilization of mobile networks and devices, mobile database systems have become a prominent method of data access. Data maintenance becomes a necessity for users who require mobility. Therefore, the usage of mobile database systems provides a convenient way of data creation, collection and management through mobile networks. Wikipedia defines a mobile database system as â€Å"a database that can be connected to by a mobile computing device over a mobile network. The client and server have wireless connections. A cache is maintained to hold frequent data and transactions so that they are not lost due to connection failure. A database is a structured way to organize information. This could be a list of contacts, price information or distance travelled†[ (Wikipedia: mobile databases) ]. Information access and organization becomes the central theme behind mobile database systems. The appeal belongs to the fact that the users are able to access data on-the-go. There are several key components to mobile database systems. They include servers, software and devices.Database Management System and Data Various software manufacturers offer mobile database systems software for use on mobile devices. The software is a vital part of operating and maintaining mobile database systems. Such software is needed to achieve the desired effect of creation, collection and management of data during a time where quality, productivity and efficiency of work or personal data is needed to maintain so form of normalcy. The standard laptop and/or mobile devices are usually able to connect to servers for information request by the users and then have the information processed for ata retrieval or collection. Mobile database functionality has a two part existence; one, connectivity and two, a mobile device. In order to have a true mobile database system, one component cannot exist without the other. Such factors make the mobile database systems operational for end-users. Wikipedia depicts the functionality of mobile database systems as follows: â€Å"Sybase is still a major force in the enterprise mark et after 25 years of success and improvements to its Adaptive Server Enterprise product. Although its market share dwindled for a few years, it's returning with powerful positioning in the next-generation transaction processing space. Sybase has also thrown a considerable amount of weight behind the mobile enterprise by delivering partnered solutions to the mobile device market†(Hess, 2010). Server quality is important to mobile database systems and their users due to the retrieval of information anywhere at any given time and that processing units and their users are immobile at the time of data processing. Sybase has supported the mobile device market in the development of server 3 products. Mobile networks and devices are also necessary components, much like the servers. Connectivity is usually is done through user commands sent to the server for data accessing. Connectivity is significant for the exchange of data from the server to the device; users at this point can do whatever they desire with the data upon connecting to the server. Mobile database systems have made major strides in the last five years in order to achieve an information management mobile platform; much in part to the new and latest technology in mobile devices and server development. The speeds and rate at which a mobile device connects has increased over time to reflect the progress the mobile technology industry has seen in database system management. With the advent of smartphones and 3G networks, mobile database system management has made its mark into a data driven society.
