Energy usage may be defined as the process of consuming or utilizing any resource of energy over a period of time.
Replacing old street lights with solar-powered lights are not sufficient to reduce energy usage. While it is not possible to turn off traffic lights on weekends because a lot of people enjoy their holiday by roaming out.
It is also not possible to appoint traffic cops in place of traffic lights because they are human and not able to maintain enough conditions that provoke citizen's safety.
