• Its about conservation STUPID!
• first law of thermodynamics which states that
  although energy can be converted from one form to
  another, the total amount of energy does not
  change (also referred to as conservation of
  energy).
• In other words, energy cannot be created or
  destroyed.

• To Conserve is to Understand
• Energy power X time
• Energy is the measure of power used
• Kilowatts per hour (kWh)
• Monthly totals of kWh is called Demand
