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

Opportunities to Reduce Energy Consumption Improper selection of optimal systems Inadequate maintenance of energy using systems Lack of understanding of energy costs

EIO-LCA EIO-LCA is an internet based tool that estimates the materials and energy resources required for, and the environmental emissions resulting from all activities associated with a product or process. It evaluates the environmental impacts of a product or process over its entire life cycle. It also analyzes the total emissions during a life cycle based on the information from industrial transactions.

EIO-LCA While performing a LCA, the user needs to choose an appropriate model, industry and sector, monetary amount for the chosen sector, and category of results to obtain as an output from the tool.

EIO-LCA Example

MotorMaster The U.S DOE MotorMaster helps to analyze motor and motor system efficiency for all the motors in a plant and suggest replacements for less energy efficient units. The program generates a payback period for the motors to replace existing motors with more efficient motors.

Observations There is a reduction of 67,628 kWh of electricity usage at facility XY compared to 579,883 kWh at facility BC. It was observed that there is an annual savings of nearly $6,500 for the facility XY when compared to over $55,000 of facility BC. The EIOLCA results indicate that the reduction in GHG at facility XY is 60.1 metric tons of CO 2 e while it is 530 metric tons of CO 2 e at facility BC. Even though the quantities are higher for each criteria at facility BC when compared to facility XY, the percentage reduction at facility BC for all the criteria is nearly 30% while it is approximately 75% at facility XY.
