What is Green Computing and Their Types

Green Computing

Green computing is the time period that is used to indicate the profitable use of assets in computing. It is also called Green IT. Green Computing means eco-friendly use of computers and their resources with the help of the environment. It is also known as the study and practice of designing, manufacturing, and the usage of eliminating computers, and servers subsystems.

In 1992 US (United States) Environmental Protection Agency launches a system name Energy Star, it is an independent labeling program that helps to promote and observe the energy capability in monitors, climate control equipment, and other technologies.

Example of Green Computing

A renewable energy source is the best example of green computing. Renewable energy sources are those energy sources that are gathered from sustainable assets which might be evidently refreshed on a human timescale like sunlight, wind, rain, waves, and geothermal heat. They are available freely, are environmental quality and generate much less pollution.

Types of Green Computing

  • Solar Power System
  • Wind Turbine Program
  • Geothermal Power

Solar Power System

The solar power system is a program in which we utilize the sunlight and produce the solar power of personal and commercial usage. California, Spain, and Canada have the first position to bring about this technology. When we talk about green computing then solar panels are the most amazing example because it easily converts electrical power into electrical energy.

Wind Turbine Program

The next and the great type of green computing is Wind Turbine System and with the help of this type, anyone can generate electrical power. After implanting the wind turbine program there is no bad effect that has been seen in the environment. It helps to decrease the outflow of carbon dioxide. Wind Turbine Program is very costly to set up, so it is not possible for everyone.

Wind Program

Geothermal Power

This is likewise an exclusive sort of green technology. With the assist of this Geothermal plants may generate electricity, and those can utilize this electricity in daily usages such as heating and cooling house.


Goals of Green Computing

The purpose of green computing is to attain economic viability and improve the way of computing gadgets. Some goals to attained in green computing are given below:

  • To decrease the implementation of unsafe products.
  • More manufacturing of energy efficiency.
  • To use the recyclability of wasted products and manufacturing unit wasted products.
  • To design the right algorithms for enhancing the computer’s efficiency.

Why We Need Green Computing?

Nowadays a computer is the basic need of every human. A computer made our life simpler and saves time and human efforts. However, the use of computer also increase strength intake and additionally generate an extra amount of heat. Greater electricity consumption and heat technology mean greater emission of greenhouse gases like Carbon Dioxide(CO2) that has various harmful effects on our environment and herbal resources. This is due to the fact we are not aware of the damaging impacts of the use of pc on the surroundings.

Instead of this, there are also other reasons why we need green computing? And the reason is that it helps to save money, save the environment, helps to decrease the risk in life, more consumption of energy, helpful to recycle waste products, it helps to inspire the workers, etc.

Approaches to Green Computing

  • Virtualization
  • Terminal Servers
  • Power Management
  • Power Supply
  • Product Recycling


It is one of the hardware reducing, cost-saving and energy-saving technology that is rapidly reworking the IT landscape and converting the manner that humans compute. On a server or a desktop system, it allows numerous operating systems and numerous applications to run on a single computer.

Terminal Servers

Terminal servers have always been used in inexperienced computing. When the usage of the gadget, customers in a terminal hyperlink to an imperative server; all of the real computing is carried out on the server. However, the end-user reports the operating gadget on the terminal.

Power Management

The ACPI (Advanced Configuration and Power Interface) is an open industry standard that allows an operating system to control the power saving of its hardware. In vintage technology, the computer consumes more electricity in which no have proper control to serve power to all a part of the computer.

Power Supply

In our old technology, our Desktop computer power supply in  PSUs (Public Sector Undertaking) is 70 to 75% and other remaining power wasted as heat power. But now the technology is change and now a computer uses an eighty percent power supply and this is possible only with the help of green computing.

Product Recycling

Recycling is one of the best and fastest growing waste streams in the world. Recycling is the process to keep changing the waste products in useful products. Growing countries like China, America, etc adopt this type of recycling very fastly.  It helps us to make our environment clean.

Advantages of Green Computing

  • Maintenance of resources means less energy required for the production, use, and disposal of products.
  • Green Computing helps to save energy and resources as well as money.
  • Green computing further includes converting government policy to enhance recycling and lowering strength use by people and businesses.
  • Reduce the hazard existing within the laptops which include a chemical known to cause cancer, nerve damage and immune reactions in humans.

Disadvantages of Green Computing

  • Green computing is very costly as it desires the latest generation to deal with the disposal process.
  • If you prefer to buy some excessive-powered green computers like the MacBook etc it will fee you at a top-class price.


Green Computing is not only a new trend; it is a generation of itself. Green Computing also helps to improve our environment and also helps to reduce pollution. It can lead to a number of energy-saving, reduction in emission of CO2 which leads to environmental protection.
