CFLEnergy Conservation and Energy Efficiency 
Two methods for reducing energy use in a facility include energy conservation and energy efficiency.  Energy conservation means using less energy by turning energy consuming products off or turning them down.  Energy efficiency means using less energy more productivity by methods such as installing more efficient heating, cooling, and lighting equipment. The Madison Lakes Park - Renewable Energy Demonstration Center will also showcase examples of energy conservation and efficiency.  This includes energy reduction strategies, such as using a ground-source heat pump for seasonal heating and cooling, replacing old halogen and incandescent light bulbs with higher efficiency and longer lasting compact florescent and LED bulbs, using programmable thermostats with "deep set-backs", and utilizing timers and photo sensors so that artificial light is only used when necessary.  Energy efficiency and conservation are just as important as investing in renewable energy resources, and usually costs less.  Becoming energy efficient will make it easier and more affordable for renewable energy strategies to be employed as less power would be needed.

Deep Set-backs 
One of the most effective strategies to reduce energy consumption is to implement "deep set-backs" on temperature when the building is unoccupied.  A set-back temperature is a temperature that differs greatly from the normal occupied temperature and is used when a building is either unoccupied, or when occupants are asleep (only for residential buildings).  Programmable thermostats, which are relatively inexpensive, can be set to automatically raise or lower the indoor air temperature according to the season to reduce energy use.  Most programmable thermostats are set so that the heating or cooling system returns the air to normal conditions one hour before the building's occupants arrive or awake.  This effectively keeps the building comfortable when it is in use and drastically reduces it's heating and cooling energy use when the building is unoccupied.
