Energy Efficiency

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

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.

Energy Equation

Energy Gap = Supply – Demand

Opportunities to Reduce Energy Consumption

Proper selection of optimal systems.

Adequate maintenance of energy using systems.

Understanding energy costs.

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.
