Sometimes to become Green, the technology has to be Smart.
For instance, a business could leave a bathroom light on all day for customer convenience, or there could be some kind of sensor that detects when a customer enters or leaves. The mini-computer would then adjust the light accordingly.
Assuming it takes less energy to run the sensor all time that it takes to run the light at all times (given that's what will probably happen if impolite customers control the light switch), then it's possible that energy could be saved in the long run, eventually recouping the cost of the sensor system itself in the energy savings.
Just like smart CPU fans too. When temperature levels are low due to low CPU usage, then mechanical fan slows down. When usage rises, temperature rises, and sensors tell the fan to speed back up, thus saving the user some amount of energy and wear&tear on the moving parts.
