What type of awareness is a company practicing if it requires that all lights be shut off after leaving a room?

This company is practicing energy awareness.

In general, energy awareness is about understanding;

- how much energy is used (directly and indirectly),

- what is it used for,

-where the energy comes from,

- the effects of using it (depletion of resources, environmental impact),

- what can be done to reduce energy consumption.

All lights out after leaving a room is a great example of a single measure of energy saving (no lights on = no energy wasted). It is an easy change that can become a habit and it can also show the company workers that they have the power to make an immediate difference to their office's energy consumption.
