Energy Consumption Per Person

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 b: of or relating to a lifestyle involving the use of sustainable methods

Actually, It’s Easy to be all of these things…

Existing Facilities Whether it is residential, commercial or industrial, Success is in 5 areas… –Space Conditioning –Lighting –Envelope –Ancillary Appliances –Process

Summary of All Programs

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.
