Green Computing applications

  • Connected heating and lighting: The popularity of connected devices for heating and lighting (through IoT), such as smart thermostats and LED technologies, is increasing. This helps to lower energy consumption by allowing you to control them with a smartphone app.
  • Electric vehicles: Vehicles may now be powered by electricity rather than gasoline, allowing them to run on electrical power. And nowadays, with so many people seeking solutions to combat climate change, green computing is in great demand. This explains why various manufacturers like Toyota, Tesla, and others offer a variety of alternatives.
  • Data centers: Electricity usage is a significant strain on data centers, which are also expensive. The world’s top technology companies, such as Google, Amazon, and Apple, attempt to construct energy-efficient data centers with minimal environmental effect and cost.
  • Alternative energy: Large IT corporations are now using alternative energy sources such as wind power, solar energy, and others to power their data centers.
  • Recycling devices: Computers, mobile phones, and other electronics contain hazardous chemicals, precious metals, and other pollutants. Making them on a large scale is dangerous, so businesses are beginning to recycle these wastes.

Wireless networking, cloud computing, edge computing, parallel computing, and other applications are all examples of green commuting.

How can a company adopt Green Computing?

Green computing encompasses IT systems, with people, hardware, software, and networks involved. So if you wish to utilize green computing, you must consider each of these elements. You must also include end-user satisfaction, regulatory compliance, good management, and a positive return on investment in your solution.

These are some of the strategies that an IT firm and other businesses can use to embrace environmentally responsible computing:

Increasing product lifespan

Green computing demands that products be designed to have a longer lifespan, reducing e-waste and preventing the need to manufacture more. You may also promote modularity and upgradeability in your advertisements. Consequently, instead of constructing the system as a whole, small modules or components may be manufactured and replaced to improve it.

Server design

Data centers use a significant quantity of total energy worldwide, about 100-200 times more than typical offices. Data centers can utilize green computing to develop environmentally friendly data center facilities. It must consider all aspects of energy consumption, from IT devices and equipment for air conditioning, heating, cooling, and ventilation to building constriction and position.

Green IT must be a core tenet of corporate strategy. Businesses should pay attention to the best data center design practices in different places, including IT systems, electrical systems, cooling systems, climatic factors, air management, waste heat recovery, and electrical generation on site. Simultaneously

Optimizing software

The most significant methods to improve and deploy software are:

  • Virtualization: Virtualization refers to abstracting or dividing computer resources such as processors, storage, memory, and so on into virtual computers or virtual machines (VMs). Two or more virtual instances may run on a single robust physical system. It reduces cooling and power consumption by eliminating the need for original hardware while also reducing resource usage. Furthermore, it lowers the need to produce more hardware. Virtualization allows servers to operate efficiently and reduce energy consumption when not in use. They’re either on or asleep. Many service providers now offer software for virtual computing since this technology is energy efficient.
  • Creating efficient algorithms: The number of resources needed for a computing function is influenced by efficiency algorithms. For example, speeding up a search algorithm can substantially lower resource consumption. As a result, IT organizations must ensure that their developers write better and more efficient code.
  • Allocating resources strategically: IT teams can use machine learning algorithms to route data to a data center with cheaper energy. It lowers the cost. Using this method, they may also direct traffic away from a data center experiencing warmer weather.
  • Using terminal servers: A terminal server is a server or hardware device that provides terminals such as PCs, smartphones, tablets, printers, and other devices with a single connection to the terminal server. Terminal servers eliminate the need for terminals to have their network interface, modem, or card. You may save energy by using terminal servers while also saving money.

Power management

Power management is a significant step toward environmentally friendly computing. And, regardless of how big or little a business is, it can do so and preserve the environment.

However, an open industry standard called the Advanced Configuration & Power Interface (ACPI) allows systems to shut down their components, such as hard drives and displays, automatically without user interaction.

When most of the system’s components switch off, such as RAM and CPU, you may hibernate it. In addition, some applications allow you to manually change CPU voltages to save energy and produce less heat.

Furthermore, tiny hard disk drives use less energy than larger versions. Solid-state drives (SSDs) store data in DRAM or flash memory, which consume even less power. They have no moving parts and so consume even less electricity.

IT firms must also handle power in GPUs – one of the most power-consuming components in computers. Instead of using a shared terminal, desktop sharing client, etc., use energy-efficient tactics such as no graphics cards instead of a shared terminal or desktop sharing client. When idle, select a GPU that consumes less electricity.

Material recycling

Recycling electronic equipment is another excellent method to embrace green computing. It will prevent hazardous chemicals such as mercury, lead, and cadmium from landfills. You can also recycle equipment rather than manufacturing it again, saving energy and reducing emissions.

IT businesses may also re-purpose or give old computers to non-profit and charity organizations. Old computer parts are recycled, such as paper, batteries, and printer cartridges. However, when recycling old computers due to privacy concerns,

Cloud, edge, and parallel computing

Cloud computing aids information technology (IT) organizations adopt green computing by addressing resource consumption and energy use concerns. Virtualization, energy-efficient data centers, multi-tenancy, and other methods allow cloud computing to minimize energy consumption and carbon emissions. Cloud computing obsoletes the necessity for energy-consuming data centers.

Furthermore, edge computing allows you to distribute processing near the clients, lowering costs. It enables smaller data centers with less energy use and cost expense.

Parallel computing likewise aids lower energy usage by allowing numerous little-scale computations or procedures to be carried out simultaneously on multiple processors that interact via shared memory rather than on separate hardware, which consumes more power.


The popularity of remote work is increasing rapidly, especially following the Covid-19 breakthrough. Teleconferencing and working from any place have advantages, including lower travel emissions, employee convenience, and higher profit margins due to minimal office upkeep.


Today, several of the most pressing issues include global warming and climate change. Pollution levels are on the rise across all three domains. Green computing is a valuable method for mitigating these environmental concerns. It may help with greenhouse gas emissions, increasing waste production, fossil fuel combustion, natural resource exhaustion, etc.
