Slide 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.
Slide 4
Energy Efficiency Efficient use of energy to obtain desired
outputs that involves using alternative technologies operating at
lower energy inputs for same purpose.
Slide 5
Opportunities to Reduce Energy Consumption Improper selection
of optimal systems Inadequate maintenance of energy using systems

P2 Tools P2 GHG Calculator: The GHG Calculator is a tool to
calculate changes in GHG emissions from P2 projects. Converts the
activity values entered (e.g., kWh saved, gal. water reduced, etc.)
to CO2e Aggregates GHG reductions from individual projects and
categories Addresses: Electricity Conservation, Green Energy,
Greening Chemistry, Water Conservation P2 Cost Calculator
Calculates the financial dollar savings from implementing a P2
activity New capacity for end users to enter in OWN unit cost per
project, and different costs per project. Addresses: Hazardous
Inputs and Wastes, Air Emissions, Water Pollution, Water Use,
Energy, Electricity, Non-Hazardous Inputs and Solid Waste

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.
Slide 16
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.
Slide 17

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.
