Alternate Energy In Arkansas Ppt

  1. 1. Alternate Energy In Arkansas<br />By: Elizabeth Nolen<br />
  2. 2. Introduction<br />Completed a research project on alternative energy in Arkansas.<br />I chose this subject because:<br />it is a current global issue<br />it is part of the 7th and 8th grade science frameworks<br />
  3. 3. Objectives<br />To define different forms of alternative energy<br />To find out what alternative energy was already in existence in Arkansas<br />To find out what alternative energy forms are possible and valuable in Arkansas<br />
  4. 4. Hypothesis<br />Hydroelectric power is possible and valuable in Arkansas.<br />Solar power is possible but not very valuable in Arkansas.<br />Wind power is possible but not very valuable in Arkansas.<br />Nuclear power is possible and valuable in Arkansas.<br />Biomass is possible and very valuable in Arkansas.<br />Geothermal power is possible and valuable in certain parts of Arkansas.<br />
  5. 5. Methods and Materials<br />Researched on Internet<br />Interviews and Emails for information and pictures<br />Took a few pictures myself<br />Used the computer, digital camera, National Inventory of Dams database<br />
  6. 6. Results and Discussion<br />On the following slides I have information about each type of alternate energy.<br />Definition<br />Availability and Value in Arkansas<br />
  7. 7. Hydroelectricity<br />Hydroelectricity is formed by converting the kinetic energy from flowing or falling water into electricity.<br />This is done by the use of hydroelectric dams.<br />In order to take advantage of this energy source, you must have access to a body of water.<br />Narrows Dam, Murfreesboro<br />
  8. 8. Hydroelectricity in Arkansas<br />There are over 1200 dams in Arkansas. <br />Only 6 have hydroelectricity as their primary purpose.<br />Out of 525 others, 14 have hydroelectricity as “other purpose”. The primary purpose for these is either flood control or recreation.<br />
  9. 9. Hydroelectricity in Arkansas<br />Hydroelectricity is possible and very valuable to Arkansas as long as you are near a body of water.<br />Carpenter Dam, Hot Springs<br />
  10. 10. Wind Power<br />Wind power is formed by converting the kinetic energy of wind into a useful energy, such as electricity. <br />This is done using wind turbines.<br />Wind power produces about 1.5% of the worlds electricity use.<br />St. Thomas Episcopal Church,<br />Springdale<br />
  11. 11. Wind Power In Arkansas<br />Wind power in Arkansas is shown by “wind output” maps. <br />Wind outputs comes in 7 classes, with 1 being the lowest and 7 being the highest.<br />Arkansas’ wind output is pretty low in most of the state. The highest classes are in the Ozark and Ouachita Mountain areas.<br />
  12. 12. Wind Power in Arkansas<br />Wind power is possible and valuable in Arkansas, but only in certain areas.<br />Arkansas wind installments<br />Carroll Electric Cooperative Windmill,<br />Ponca<br />
  13. 13. Solar Power<br />Solar energy converts the radiant energy from the sun into different forms.<br />There are different ways to collect and convert the energy.<br />Flat-Plate (solar panel)<br />Solar Concentrator (tracks the sun)<br />The most expensive part of solar energy is storing it.<br />Clinton Presidential Library in <br />Little Rock uses rooftop solar <br />Panels to power the library archives<br />
  14. 14. Solar Power in Arkansas<br />Solar output data in Arkansas shows that like wind output, Arkansas is in the middle. <br />Flat-Panel solar collectors are more likely to be valuable in Arkansas than the solar concentrators. <br />Solar power is possible in Arkansas but only valuable when using flat-panel collectors.<br />Trice Elementary School, Texarkana<br />Fayetteville High School, Fayetteville<br />
  15. 15. Solar Power in Arkansas<br />Flat panel collectors<br />4500-5500 Watt hours/sq meter<br />Solar Concentrators<br />3500-4000 Watt hours/sq meter<br />
  16. 16. Biomass<br />“Biomass refers to all of the Earth’s vegetation and all the products and co-products that come from it.” (from<br />Any waste product of farming could be used to produce biomass energy, including livestock waste and burning wood.<br />Biomass is already a natural part of the carbon cycle, so why not use it more readily?<br />
  17. 17. Biomass in Arkansas<br />Usually when biomass is mentioned, people think of biofuel. <br />In Arkansas, 27 counties have biofuel suppliers.<br />19 of these are located along the Mississippi river.<br />Biomass is possible and VERY valuable in Arkansas if people would use it.<br />
  18. 18. Nuclear Power<br />Nuclear power refers to any nuclear technology used to produce usable energy from atomic nuclei using controlled nuclear reactions. <br />Reactors heat up water, then the steam that is produced is converted to mechanical energy for the production of electricity or propulsion.<br />Nuclear Powered Ships<br />
  19. 19. Nuclear Power in Arkansas<br />Nuclear power plants are possible anywhere, as long as there is enough land in the right spot.<br />Of 31 states with nuclear energy, Arkansas ranks 18th with Arkansas Nuclear One power plant near Russelville. <br />This plant consists of two units. <br />These 2 units are 2/5 used by ENTERGY in the southeast.<br />
  20. 20. Geothermal Power<br />Geothermal power is energy that is from extracted heat from inside Earth. (geo=earth, thermal=heat)<br />Geothermal energy has been used for centuries. People would use the heat from the earth to cook and heat their homes. <br />Geothermal energy is always going to be there and there is no need to transport the fuel because geothermal plants are usually built on top of the source.<br />
  21. 21. Geothermal Energy in Arkansas<br />In the Mid-South, about 10 ft below Earth’s surface, temperature averages about 58° F. This makes the Mid-South ideal for geothermal heating<br />The first known commercial use in the US was in bath houses in Hot Springs. <br />Geothermal energy is possible and valuable in Arkansas, particularly around the Hot Springs area. <br />
  22. 22. Conclusion<br />
