P3: sustainable energy
  1. ELECTRICAL ENERGY
    1. power
      1. is the rate of energy transferred
        1. power is measured in:watts, W, killowatts,KW
          1. energy transferred = power X time
          2. kilowatts
            1. energy is meausred in in joules
              1. kwh
                1. energy transferred = power X time
                2. the formular for electricalpower is: power(in W) = voltage(in V) Xcurrent (in A)
                3. SAVING ENERGY
                  1. at home
