EGEE 102, Lesson 1 Review

Review Sheet - Energy and Society

  • Forms of Energy
    • Mechanical energy
      • Potential Energy
      • Kinetic Energy
    • Chemical Energy
    • Thermal or Heat Energy
    • Electrical Energy
    • Nuclear Energy
      • Fission
      • Fusion
    • Radiation
  • Electromagnetic Spectrum
    • The lower the energy, the longer the wavelength and lower the frequency, and vice versa
  • Energy can be converted from one form to another
  • Units of Energy
    • BTU, Calorie, calorie, Joules, kWh, Therm
    • Food Calorie (usually written with 'C')
    • calorie (usually written with 'c')
    • 1 Food Calorie = 1000 calories
  • Units of Power
    • Watts
    • kW (kilo-watts)
    • J/s
    • HP
    • cal/s
  • Sources of Energy
    • Renewable
      • Can be replenished over and over again; they are never depleted
      • Hydropower, Solar, Wind, Tidal, Geothermal energy from inside the earth, Biomass from plants, Nuclear Fusion
    • Non-renewable
      • Cannot be replenished over and over again; they get depleted
      • Fossil fuels, Tar Sands, Nuclear Fission
    • Fossil Fuel Distribution
      • US has a lot of Coal reserves
      • Middle East has a lot of petroleum reserves
  • Definitions
    • Power is the rate at which we do work
    • Energy is the capacity to do work
    • Work is the amount done
  • Power = Energy / Time
  • Energy = Power x Duration of Usage (time)
  • Energy consumption/day = Power consumption x hrs used/day
