    • Alternate Energy In Arkansas
      By: Elizabeth Nolen
    • Introduction
      Completed a research project on alternative energy in Arkansas.
      I chose this subject because:
      it is a current global issue
      it is part of the 7th and 8th grade science frameworks
    • Objectives
      To define different forms of alternative energy
      To find out what alternative energy was already in existence in Arkansas
      To find out what alternative energy forms are possible and valuable in Arkansas
    • Hypothesis
      Hydroelectric power is possible and valuable in Arkansas.
      Solar power is possible but not very valuable in Arkansas.
      Wind power is possible but not very valuable in Arkansas.
      Nuclear power is possible and valuable in Arkansas.
      Biomass is possible and very valuable in Arkansas.
      Geothermal power is possible and valuable in certain parts of Arkansas.
    • Methods and Materials
      Researched on Internet
      Interviews and Emails for information and pictures
      Took a few pictures myself
      Used the computer, digital camera, National Inventory of Dams database
    • Results and Discussion
      On the following slides I have information about each type of alternate energy.
      Definition
      Availability and Value in Arkansas
    • Hydroelectricity
      Hydroelectricity is formed by converting the kinetic energy from flowing or falling water into electricity.
      This is done by the use of hydroelectric dams.
      In order to take advantage of this energy source, you must have access to a body of water.
      Narrows Dam, Murfreesboro
    • Hydroelectricity in Arkansas
      There are over 1200 dams in Arkansas.
      Only 6 have hydroelectricity as their primary purpose.
      Out of 525 others, 14 have hydroelectricity as “other purpose”. The primary purpose for these is either flood control or recreation.
    • Hydroelectricity in Arkansas
      Hydroelectricity is possible and very valuable to Arkansas as long as you are near a body of water.
      Carpenter Dam, Hot Springs
    • Wind Power
      Wind power is formed by converting the kinetic energy of wind into a useful energy, such as electricity.
      This is done using wind turbines.
      Wind power produces about 1.5% of the worlds electricity use.
      St. Thomas Episcopal Church,
      Springdale
    • Wind Power In Arkansas
      Wind power in Arkansas is shown by “wind output” maps.
      Wind outputs comes in 7 classes, with 1 being the lowest and 7 being the highest.
      Arkansas’ wind output is pretty low in most of the state. The highest classes are in the Ozark and Ouachita Mountain areas.
    • Wind Power in Arkansas
      Wind power is possible and valuable in Arkansas, but only in certain areas.

      Ponca
    • Solar Power
      Solar energy converts the radiant energy from the sun into different forms.
      There are different ways to collect and convert the energy.
      Flat-Plate (solar panel)
      Solar Concentrator (tracks the sun)
      The most expensive part of solar energy is storing it.
      Clinton Presidential Library in
      Little Rock uses rooftop solar
      Panels to power the library archives
    • Solar Power in Arkansas
      Solar output data in Arkansas shows that like wind output, Arkansas is in the middle.
      Flat-Panel solar collectors are more likely to be valuable in Arkansas than the solar concentrators.
      Solar power is possible in Arkansas but only valuable when using flat-panel collectors.
      Trice Elementary School, Texarkana
      Fayetteville High School, Fayetteville
    • Solar Power in Arkansas
      Flat panel collectors
      4500-5500 Watt hours/sq meter
      Solar Concentrators
      3500-4000 Watt hours/sq meter
    • Biomass
      “Biomass refers to all of the Earth’s vegetation and all the products and co-products that come from it.” (from arkansasenergy.org)
      Any waste product of farming could be used to produce biomass energy, including livestock waste and burning wood.
      Biomass is already a natural part of the carbon cycle, so why not use it more readily?
    • Biomass in Arkansas
      Usually when biomass is mentioned, people think of biofuel.
      In Arkansas, 27 counties have biofuel suppliers.
      19 of these are located along the Mississippi river.
      Biomass is possible and VERY valuable in Arkansas if people would use it.
    • Nuclear Power
      Nuclear power refers to any nuclear technology used to produce usable energy from atomic nuclei using controlled nuclear reactions.
      Reactors heat up water, then the steam that is produced is converted to mechanical energy for the production of electricity or propulsion.
      Nuclear Powered Ships
    • Nuclear Power in Arkansas
      Nuclear power plants are possible anywhere, as long as there is enough land in the right spot.
      Of 31 states with nuclear energy, Arkansas ranks 18th with Arkansas Nuclear One power plant near Russelville.
      This plant consists of two units.
      These 2 units are 2/5 used by ENTERGY in the southeast.
    • Geothermal Power
      Geothermal power is energy that is from extracted heat from inside Earth. (geo=earth, thermal=heat)
      Geothermal energy has been used for centuries. People would use the heat from the earth to cook and heat their homes.
      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.
    • Geothermal Energy in Arkansas
      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
      The first known commercial use in the US was in bath houses in Hot Springs.
      Geothermal energy is possible and valuable in Arkansas, particularly around the Hot Springs area.
    • Conclusion
