Set Your Own Schedule: Tell Edison when you use your computer most and set energy preferences for those work and non-work times.

Save Little Or Lots: Use the Edison efficiency slider to choose the level of energy savings you want to achieve.

See Your Savings: Edison will calculate and display your estimated savings based on the setting you choose.
