As the world is stepping towards the future, people have begun to realize how fast they are exhausting their natural resources.

Every effort is being made to conserve all kinds of energy, and so is it for non-renewable energy sources. A technology is being developed which would help us reduce our great dependence on non-renewable energy resources, thereby cutting down on carbon emissions.

This smart device is the light-emitting diode or in short LED.

LED will help enable a wireless technology based on visible light, replacing the now used radio frequency. Boston University 's College of Engineering under a grant from the National Science Foundation is working on such a device. The purpose of this project is not only to conserve electricity and in turn cut down the usage of ecological resources, but also to produce a wireless facility which would help access data and create smooth communication with just a glow of natural light. As for electricity, the consumption would definitely go down, hence saving on the bills.

How apt or efficient this technology would be is yet for us to see, but even so we wait with abated breath for this smart lighting to be launched.
