Interesting Fact
For every reduction in Kwh….
2 pounds of Carbon Dioxide reduction
Interesting Fact
• It’s A Paradox.
• LES Is Not Driven By Increasing
Sales.
• LES Is Driven For Increasing
Efficiency In System Operations.
Is it Conservation…
• Conservation, By Webster
a careful preservation and protection of
something ; especially : planned
management of a natural resource to
prevent exploitation, destruction, or
neglect 2: the preservation of a
physical quantity during
transformations or reactions
…or Efficiency…
• Efficiency, by Webster's
effective operation as measured by a
comparison of production with cost
(as in energy, time, and money) (2):
the ratio of the useful energy
delivered by a dynamic system to the
energy supplied to it
…or Sustainability?
• Sustainability, by Webster's
of, relating to, or being a method of
harvesting or using a resource so
that the resource is not depleted or
permanently damaged <sustainable
techniques> <sustainable
agriculture> b: of or relating to a
lifestyle involving the use of
sustainable methods
Actually, It’s Easy to be all of
these things…

Whether it is residential, commercial or
industrial, Success is in 5 areas…
– Space Conditioning
– Lighting

– Process
LES’
Sustainable Energy Program
Goals
1. Financial savings to the consumer;
2. Mitigation of year-to-year system load
growth; and
3. Concerted effort to reduce peak load
impact.
Year 1- Potential reduction of 6.4 MW in
demand and 13,246 MWh in energy.

Renewable Energy Status
• LES Board direction to acquire up to 15 Mw.
• LES is in the process of acquiring 9 Mw of wind
energy from NPPD.
• Limited transmission access has slowed the
finalization of contract.
• A total of 6.5% total energy from Renewable
Resources
Final Comments
• Energy Conservation, Efficiency,
Sustainability is support by Electric
Utilities.
• It makes cents.
• It is easy.
