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'sof, 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…
