LED : new weapon in our fight against global warming

When it comes to bright ideas, LED lights (or light-emitting diodes) are incredibly energy efficient and long lasting. Unlike traditional incandescent or even CFL bulbs, they illuminate when the movement of electrons across semiconductor creates light. Historically, they've been too expensive to be practical for most residential use, but companies are working to make it more affordable for consumers to have at home. In the following posts we will learn more about potential advantages of LED lights and how they work but for now here's a simple diagram to  give you a glimpse of what could be a potential boon for mankind and a very useful method in our fight against global warming and a boon for our future generations.
