Energy Conservation Essay Example for Free

Energy Conservation Essay Energy conservation is the reduction of quantity of energy used. Energy conservation supports the eco friendly lifestyle by providing energy, which saves your money and at the same time saves the earth. When you decrease the amount of energy you use you automatically make efforts to reduce increasing global warming. Source of Energy Conservation: Solar Energy: Solar power uses the suns energy and light to provide heat, light, and electricity for homes. It is the primary source of all energy forms on the earth. It is one such energy which helps in maintaining the ecological balance through the process of photosynthesis and green house effect. We have been using sun to dry clothes and boil food for generations. But now number of techno powers which have been developed to make full use of solar energy such as: Photovoltaic systems : By these systems the electricity could be produced directly from the sunlight. Solar Process Space heating and cooling : It is the commercial and industrial use of suns heat. Solar Hot Water : The process to heat water with the solar energy. Solar Power plants : Producing electricity bu using the suns heat. Passive Solar heating and daylighting : Use solar energy to heat buildings. Wind energy : Wind energy is often used to generate the mechanical power or the electricity. In the country like India, wind energy holds the great importance because of large hilly, coastal and desert areas. In the rural areas it is used to pump water and grind grain. The benefit of wind energy is that it is fully pollution free and is eco friendly too. It costs low and the generation of power is continuous. It is the most effective way to conserve the energy and prevent the environment. Geothermal Energy : Geothermal energy is used in the form of thermal energy, electrical energy, nuclear energy, mechanical energy, chemical energy and light energy. It uses heat energy from beneath the surface of the earth. It was first used to produce electricity in the Itlay in 1903. Geothermal energy has the major environment benefit as it prevents air pollution. It is particularly important in the inland nations such as Indian Oceans and the pacific regions. Energy generation from geothermal sources is only possible in few places under unique geographic conditions. Wave energy : Ocean waves contain large amount of energy, which can be extracted through Ocean winds, Ocean currents, Ocean Geothermal etc. if the barrage is built across the river, electricity can be obtained by by the flow of water through turbines as the tide rise and falls. Hydroelectric energy : Another renewable source of energy is the hydroelectric energy, which is produced from fast flowing water. The process is pollution free. The movement of water spins the turbines which in turn generate electricity. Biomass energy : Biomass is the plant and animal waste which is used as the energy. Biomass energy like manure from livestock, plant waste etc can be used to generate electricity, fuel, light, and heat. We get biomass energy directly from plants and indirectly from the animal waste.

Andrew Johnson - A Short Analysis :: essays research papers

President Andrew Johnson lifted himself out of extreme poverty to become President of the United States. He was a man with little education who climbed the political ladder and held many different high offices. As a strict constitutionalist, Johnson believed in limiting the powers of the federal government. President Johnson was one of the most bellicose Presidents who â€Å"fought† Congress, critics, and many others. President Andrew Johnson faced numerous problems post-Civil War Era including reconstructing the Southern states to combine peacefully with the Union, his battles with Congress, and his career ending impeachment. Following Lincoln’s tragic assassination, President Andrew Johnson took on the accountability of making Reconstruction a reality. Andrew Johnson wanted to use Lincoln’s ideas of reconstruction but in a modified form. Since Congress would be in recess for eight more months Johnson decided to go ahead with his plan. Johnson's goal in reconstruction was to grant amnesty to all former Confederates (except high officials), the ordinances of secession were to be revoked, Confederate debts would repudiate, and the states had to ratify the Thirteenth Amendment. Once the states swore to a loyalty oath to abide by the conditions they would be allowed to return to the Union. After swearing to the oath Confederate States would be allowed to govern themselves. With this power the states implemented the creation of a system of black codes that restricted the actions of freed slaves in much the same way, if not exactly the same way, that slaves were restricted under the old law. The e nd result of his plan was a hopeless conflict with the Radical Republicans who dominated Congress, passed measures over Johnson's vetoes, and attempted to limit the power of the executive concerning appointments and removals. As soon as Johnson was made president he began to disagree with Congress, particularly those Congressional members of his opposing party. Later, he even broke ties with his own party citing the fact that he wouldn’t endorse a new amendment to the Constitution granting blacks the rights of citizenship. Congress did not approve of President Johnson’s plans for Reconstruction. The Wade Davis Plan returned power to the same people who had tried to break the Union by granting them amnesty. The Congress mainly opposed this plan because it contained no provision to protect the free slaves. The Freedman’s Bureau Act was intended to help former slaves to shift from slavery to emancipation and assured them equality before law.

Purchasing can be traced as far back as 2800 BC in cuneiform clay tablets purchasing orders. Curiously only during the past two countries has purchasing been addressed in trade books and text books.

Kirkman. The first college textbook on purchasing was authorized by Howard T. Lewis of Harvard University in 1933. Although interest of purchasing and supply function has been a phenomenon in the 20th, it was recognized as independent and importing function well before 1900. Growth of interest and attention to purchasing was rather uneven in the early 1900’s but by 1915, several books on purchase had appeared and several articles had been published in trade press primarily in the engineering journals. Yet prior to World War I (1914-1918) most firms regarded the purchase function primarily as a clerical activity.

This emphasis by the management on the purchasing department has been borne out to of the realization of the profit potential of purchasing as a function. Every shilling saved in purchasing is equivalent to a new shilling in profit. The profit margin of a firm is usually given as.

Kill A Mockingbird, By Harper Lee - 1327 Words

To Kill A Mockingbird Argumentative Essay, Atticus Takes a Stand It makes sense for Atticus to defend Tom Robinson, even if others thinks it s stupid just because of Tom’s color. Harper Lee was the Author of the number one book in America, To Kill A Mockingbird. The book starts off with Scout talking about her family, Jem and Atticus. Then Scout talks about someone named Dill, who comes only during summer. When Dill did come over, Jem, Scout, and Dill would try to get Boo Radley to come out of his house. The kids were afraid of Boo; and when Scout told Atticus that they were trying to get Boo out of his house, Atticus told them to stop because they didn t know how he feels and that â€Å"you never really understand a person until you consider things from his point of view - until you climb into his skin and walk around in it† (Lee 30). This made Scout understand how Boo Radley felt and became less scared of him and wanted to become his friend more than anything else. But what Atticus said also ties in with his case with Tom Robinson , who is a black man being accused of rape. But, people in the book think it doesn t make sense for Atticus to defend Tom Robinson; because of Tom’s color.
