For example we can conserve energy from our street lights by automating it. We should use the lights only when there is any movement of humans. It may save more energy.

Remember last time visited malls ? 

Elevators have the sensor which detect us and start resuming. 

There are AC vents, cctvs  work in same way.

We do have lights with motion sensors which light up when movement is detected.

Still some energy would be required to keep the sensors awake!
