2. Problem Statement
The population of citizen had been increases and concentrate in city
causing the insufficient of energy usage problem even the high usage
cost expenses.
Benefits or Impacts If Problem is
solved
Since the energy usage cost had reduce, so the Malaysian enjoy the
low living cost and sufficient in resource.

5. Engineering Contradiction
If the efficiency of electrical appliance is increase then
the lesser loss of energy produce, but it necessary to
design a new product that may have high complexity
