GREEN COMPUTINGthe next wave in computing

WHAT IS GREEN COMPUTING?It is the study of using

computing resources efficiently.

The main goal of green computing is to reduce

hazardous materials , promote biodegradability and eco-friendlyComputing.

Why should we usegreen computing?

Contaminated waterways andenvironment.

Harmful to our healthBecause toxic chemicalsgenerated by computers areabsorbed our lungs.

APPROACHES OF GREEN COMPUTING

Cheap client hardware-it uses very low power and does not even require cooling fans.

Slow animated graphics-3d games or drawings are unusable on thin client.

Future of green computing New electronic products are introduced towardsenergy saving.

Combine ecology with technology using Solar technology in Keyboards.

Green materials are Developed every year.

THINK ABOUT ITAsk yourself if you really need to print that document?

Tips for Green computing Look for energy efficient devices.

Switch off screens and other devicesat night.

Use server and web basedapplications. apply the famous concept of 3R’s
