Wastricity is the use of electricity in a way that provides no personal or public benefit.
There is no public benefit to the money spent lighting streets and the exterior of buildings during the daytime. Who should you talk to when you see municipal money being spent on electricity or other utilities for zero constructive use? How will they respond when you point out that they are burning their budget? Are they planning on going in front of the voters asking for some emergency reprieve in the budget meltdown of the year?
In our personal lives, we use wastricity whenever we leave our phone chargers plugged in to the wall when the phone is not attached. We also use wastricity by leaving gaming systems running while we are out of the house. Leaving lights on in the room when nobody is in the room is classic wastricity.
