As we move towards the future we are beginning to realize that many of the processes that we use in our everyday lives are becoming outdated and harmful not only to us, but also to the environment that we live in. We are looking to make changes in our lives to help not only ourselves but our future generation, thus I believe that we must now start taking these steps. We must start to use other types of energy to ensure that this planet has a future. We need to move away from the current methods of energy that we are using, and towards methods that do not have the horrible effects on the environment that our current methods have. Maybe we can not totally abandon our currents methods within 30 years but we must start to cut back on the current devastation that we are inflicting on our environment. I.
Introduction A. In this section I will discuss more of what I was talking about in the previous section, including more in depth the other possible methods that we should start investigating for future use. II. Modified Introduction This section will contain information about the type of energy that the world currently uses. A.
Our current source of energy either comes from the burning of fossil fuels +can be a very cheap energy source – within a few hundred years all of the fossil fuels will be depleted – Greenhouse effect B. Or the splitting of atoms. +effective source of energy +able to produce a great amount of energy fairly easily -environmental impact III. This section will contain information on the negative aspects and positive aspects of the current types of energy sources that we are now currently using. A. the cost effects B.
The Essay on Mixed Methods Start
Mixed methods research (MMR), although in has been defined in several different ways (see Johnson at al); most explanations are consistent in that it is essentially characterised by the employment of both qualitative and quantitative elements in a single study. (Johnson, et al., 2007, pp. 118-121; Niglas, 2000, pp. 9-10; Creswell & Plano Clark, 2010, p. 2; The concept of mixed methods ...
environmental effects C. cultural D. social E. political IV.
Alternative Sources of energy IV A. Negatives of all these types 1. They are episodic (not always there) 2. They take up a lot of land Positives of all of these 1.
Obvious benefits to the environment A. Solar + Low costs +no harmful effects on the environment + The amount of potential energy that we receive from the sun is about 20, 000 times more than we could ever use in a year – The sun is not always out (still need a way to store this energy) B. Wind Power +Wind blows at around 10 mi / hr . the total power that can be created is around 50 watts. C. Geothermal + can create enough energy to run a turbine + uses just the natural heat (energy that is created by the earth’s core) + three mile down can reach temperatures of 100 degrees Celsius can run a steam powered electric power plant +Hot spots that are on the earth’s surface can be used currently however – Current technology – Expensive form of alternative energy -high upkeep cost on maintaining hot-spot locations D.
Tides + has been used before to produce as much as 300 MV’s of power + can be a very cheap and viable source of energy -major negative is like most of the other alternatives, it cannot always be counted on E. Hydroelectric +low maintenance costs +cheap source of power +180, 000 MV are potential in the US only a third of that is being used as of now -very high upfront costs V. Comparison of the current energy source and the sources that I believe that we should move towards. VI. How will we be able to change our practices and the possible benefits that will take place.
A. social B. economical C. political D.
environmental E. cultural VI. The conclusion A. Why we must change! B. For the present and the future C. How must we do this D.
Reinforcement of what I have talked about E. End thoughts.
