A successfully implemented energy plan improves energy and financial performance while distinguishing your business as an environmental leader
Sample Energy Plan Example of an energy policy from ABC Inc. Energy Mandate
We recognize energy as a controllable operating expense wherein lower energy consumption results in decreased operating expense, environmental emissions, and maintenance costs. Energy management is the responsibility of all staff in our facility, guided and supported by the facility/energy manager. We will assess our energy performance and share energy use data with all employees. We will create and implement an energy plan to achieve our energy goals. Our use of equipment and controls for energy savings will be a show-piece in our industry.
– ABC Inc. has established three key energy goals:
Reduce kWh energy consumption per square foot by 20% in one year
Reduce kW peak demand per month by 10%
Obtain a minimum 20% IRR on efficiency investments
Established this ______ day of ___________, 2010.
President/CEO/Director of Ops/Facility/Energy Manager/Financial Manager

Most companies with energy plans identify and implement a mix of initiatives, based on their specific business types and requirements, to reach their goals Sample Mix of Initiatives
37
Involving employees in energy conservation can be one of the most effective ways to control your company’s energy costs
Why Should Your Employees Save Energy?
Employee Reaction Suggested Response
“This Employee Energy Awareness
program only benefits the company,
not me.”
• Energy efficiency contributes to greater productivity and
larger profits for our company, leading to job security and
higher wages.
• Energy efficiency results in a more comfortable working
environment.
• Energy savings will be allocated toward employee reward
programs that recognize individual efforts.
• You can “take home” the energy-saving techniques you
learn at work, saving energy and money at home.
“I don’t have enough time and am
already too busy with my regular job
duties.”
Becoming efficient is easy and doesn’t take any additional
time. It’s a matter of small behavioral changes, and once
they become habits, they don’t take any more time than
energy-wasting habits.
“How can my small contribution really
make a difference?”
Individuals play a key role in the success of an energy
efficiency program and should be proud of their
conservation efforts. Individual actions do make a
difference. For example, If every person did X, Y would be
saved, enabling Z.

40
Other companies, even those in different industries, can lend ideas that can help your energy plan thrive
Best Practices at Work California Portland Cement Company
A subset of the company’s energy team is made up of process engineers who visit a different plant every six weeks and do an energy audit. At one plant, the process engineers focused on the finish grinding system and identified $300,000 in opportunities for annual energy savings
Toyota
“As part of our environmental activities, energy savings is listed as one of our key performance indicators,” says Bruce Bremer of Toyota. “So it’s right up there on our radar screen. Over the years, we moved it up on the company’s priorities by keeping it visible.”
Eastman Kodak
Has preferred supplier agreements to buy all its motors from preferred vendors. “With an agreement comes engineering and technical support, so when we’re doing energy assessments, we can rely on them to help us decide whether the cost of putting in a high-efficiency motor is justified,” says Kodak worldwide energy program manager George Weed
