Dear sir,
i have noticed that in our country we firmly uses lights and no one care to switch off lights when is not needed.i mark one thing that in indian railways that in majority case we found tube-lights are on in all the daytime when there is no need of lights.so if govt can arrange light sensors in every coach so we can save about 100megawatts of power every day which can lighten about 16400 homes per day.and sensor cost is not more than about a one week uses of power by trains.
