What is Energy ? … What is Power ??? Energy is what makes things happen! • Electricity is a very useful type of energy that we use every day to make things happen. Power is (basically) how fast energy is used. • We can use energy quickly, or we can use it more slowly.

Power is how much energy is transformed in 1 second. Measured in Joules per second, Watts or kilo-Watts. Electricity industry measures and charges for energy in kilowatt hours (kWh).
Example Toaster: Power rating = 2 kW Time on = ¼ hour Energy used = 2 x ¼ = 0.5 kWh Light bulb: Power rating = 100 W = 0.100 kW Time on = 5 hour Energy used = 0.1 x 5 = 0.5 kWh
