2 Energy Efficiency  Efficient use of energy to obtain desired outputs that involves using alternative technologies operating at lower energy inputs for same purpose.

3 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.

4 Energy Equation Energy Gap = Supply – Demand Total energy production and consumption, (quadrillion BTU) Source: EIA’s Annual Energy Outlook, 2007

5 Opportunities to Reduce Energy Consumption  Proper selection of optimal systems.  Adequate maintenance of energy using systems.  Understanding energy costs.

6 Energy Efficiency Act 2007: Enhance Energy Efficiency  Optimize energy efficiency.  Improve environmental performance through advanced technologies.  Train engineering and research students to conduct energy assessments.
