What is Green it ?
“The study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems — efficiently and effectively with minimal or no impact on the environment."

In 1992, the U.S. Environmental Protection Agency launched Energy Star, a voluntary labeling program that is designed to promote and recognize energy-efficiency in monitors, climate control equipment and other technologies

Government regulation, however well-intentioned, is only part of an overall green computing philosophy. The work habits of computer users and businesses can be modified to minimize adverse impact on the global environment.

Steps need to be taken

Power-down the CPU and all peripherals during extended periods of inactivity.

Power-up and power-down energy-intensive peripherals such as laser printers according to need.

Use liquid-crystal-display (LCD) monitors rather than cathode-ray-tube (CRT) monitors.

Use notebook computers rather than desktop computers whenever possible.

Minimize the use of paper and
properly recycle waste paper.

Dispose of e-waste according to federal, state and local
regulations.

Employ alternative energy sources for
computing workstations,
servers, networks and data centers.

Data centre best practices used by Google

Measure Power Usage Effectiveness

Manage Airflow
Good air flow management is fundamental to efficient data center operation. Start with minimizing hot and cold air mixing by using well-designed containment.
Eliminate hot spots and be sure to use blanking plates for any unpopulated slots in your rack. We've found a
little analysis can pay big dividends.

Adjust the thermostat
Raising the cold aisle temperature will reduce facility energy use. Don't try to run your cold aisle at 70F; set
the temperature at 80F or higher -- virtually all equipment manufacturers allow this. For facilities using
economizers (we strongly recommend it), running elevated cold aisle temperatures is critical as it enables more days of "free cooling" and more energy savings.

Use free cooling
"Free cooling" is removing heat from your facility without using the chiller. This is done by using low temperature ambient air,
evaporating water, or using a large thermal reservoir. Chillers are the dominant energy using component of the cooling
infrastructure; minimizing their use is typically the largest opportunity for savings. There is no one 'right' way to free cool -
but water or air-side economizers are proven and readily available.

Optimize Power
Distribution
Minimize power distributi on losses by eliminati ng as many
power conversion steps as possible. For the conversion steps you must have, be sure to specify effi cient equipment transformers
and power distributi on units (PDUs). One of the largest losses in data center power distributi on is from the uninterrupti ble power supply (UPS); be sure to specify a high effi ciency model. Also keep as high a voltage as close to the load as feasible to reduce line
losses.
