  1. 1. By Jeremy Harvey<br />Alternative Energy<br />
  2. 2. What Is Energy?<br />Energy is a quantity that is understood as the ability to do work. This quantity can be assigned to any particle object, or system of objects as a consequence of its physical state.<br />
  3. 3. Alternative way of Producing Energy!<br />Wind Power <br />Solar Power <br />Battery Power<br />
  4. 4. WIND POWER<br />Wind power this type of energy harnesses the power of the wind to propel the blades of wind turbines.These turbines cause the rotation of magnets, which creates electricity.<br />
  5. 5. WINDTURBINES<br />This a picture of the wind turbines used to produce energy. The blades on the turbine causes the rotations of magnets which creates energy.<br />
  6. 6. Pros and Cons of Wind Power <br />Causes no pollution<br />Beneficial to people living in remote areas that can not reach main power plants.<br />Farming and grazing can still take place in land occupied by turbines.<br />Sitting cost are low because of the ability to coexist with agricultural fields. <br />
  7. 7. Cons of Wind Power<br />Winds vary from day to day little wind causes less energy consumption.<br />May effect bird migration <br />Consider to be eyesores or obstruction because of vast size<br />Also effect radar and Doppler weather radar these radar sometimes pick them up.<br />
  8. 8. Solar power involves using solar cell to convert sunlight into electricity, using sunlight hitting solar thermal panels to convert sunlight to heat water or air, using sunlight hitting a parabolic mirror to heat water (producing steam), or using sunlight entering windows for passive solar heating of a building.wouldbe advantageous to place solar panels in the regions of highest solar radiation<br />Solar Power<br />
  9. 9. Picture of solar panels<br />
  10. 10. Pro of Solar Power<br />Imposes no fuel cost<br />Renewable resources as long as the sun exists<br />Causes no air pollution<br />Very effective for heating such as heating water, home heaters and solar ovens<br />Also very effective in remote areas where power companies can not be reached<br />
  11. 11. Cons of Solar Power<br />Much more expensive that typically ways of producing energy<br />Solar heat and electricity is not available at night and may be unavailable because of weather conditions therefore storage is needed.<br />Solar cells produce DC which must be convert to AC (using a grid tie inverter) which incurs a 4-12% energy loss<br />Chemical used to produce these cells are extremely hazardous<br />
  12. 12. Battery Power<br />Batteries are used to store energy in a chemical form<br />
  13. 13. Batteries<br />
  14. 14. Pro of battery use<br />Operation of a battery electric vehicle is approximately 2 to 4 cents per mile, about a sixth the price of operating a gasoline vehicle<br />The use of battery electric vehicles may reduce the dependency on fossil fuels, depending on the source of the electricity.<br />Battery electric vehicles have fewer moving parts than internal combustion engines, thus improving the reliability of the vehicle<br />
  15. 15. Cons of battery use<br />Current battery technology is expensive<br />Some of the principal materials required in battery production, such as Lithium, are becoming increasingly scarce <br />Some batteries (like the Gel battery and the Lead-acid battery) are highly toxic<br />Spent vehicle batteries present a potential environmental hazard<br />Some batteries perform less efficiently in cold weather, and a battery electric vehicle lacks a convenient source of waste engine heat to warm the passenger compartment<br />
