Energy Efficiency
Efficient use of energy
 to obtain desired outputs
 that involves using
 alternative technologies
 operating at lower
 energy inputs for same
Energy Assessment
A procedure to assess the power consumption with
 respect to each source.
Basic steps:
  1. Determining the amount of energy being
 consumed for each process/activity.
  2. Determining the scope for energy savings and the
 cost it takes to implement the activities.
