Information Technology has played an important part in making the world a better place, however, it also has its fair share of impacting the health of the environment. Therefore, the concept of green computing is becoming more popular.
Green computing means reducing the carbon footprint of tech gadgets. It is similar to green chemistry aimed at reducing the use of hazardous materials in manufacturing a product, maximizing energy efficiency, and increasing the biodegradability of disused products so that it does not add to the environmental waste.
History of Green Computing
The concept of sustainable computing was powered in 1992, by the Environmental Protection Agency. EPA started a voluntary labeling program called Energy Star designed to recognize electronic devices that met the energy efficiency standards.
This program laid the foundation of Sleeping Mood and other initiatives to accelerate green computing.
EPA also founded the expansion of this program with the Global Electronics Council to start the Electronic Product Environment Assessment Tool. EPEAT is a product registry that assesses the computing tools on 51 criteria and measures a product’s efficiency and sustainability attributes.
TCO certification also dates back to 1992. TCO was created by the Swedish Confederation of Professional Employees which ensured that the computer equipment purchased by employees is eco-friendly.
This program initially promoted low magnetic and electric emissions from CRT-based computing displays but was later expanded to energy consumption, use of hazardous materials in the production, and ergonomics of computer devices.
The initiatives that were taken decades ago largely contributed to the idea of sustainability in computing. According to a report in 2017, around 100 industries and governments across 22 countries are now promoting green ICTs.
Why Green Computing Is Important?
You might be thinking about how a small device like a smartphone can affect the environment. Well, here is the truth, the manufacturing of a smartphone can leave around 85% carbon footprint, making it potentially hazardous for the environment. Moreover, the production, extraction of metal, and transportation of smartphones have worsened deforestation and water pollution.
We often overlook the fact that the production of these devices uses silicon, plastic, iron, aluminum, and copper. The processes of extracting metals also induce solid and liquid waste. The production facilities in various locations around the world have also contributed to climate change.
Similarly, the manufacturing of computers, laptops, or any device that uses fossil fuel for functioning is causing a significant greenhouse effect. According to statistics, the IT sector is responsible for 5-9% of the electricity use and causes 2% of all emissions.
Furthermore, stats show that smartphones, desktops, and data centers are responsible for 11%, 7%, and 45% of the total carbon footprint of the Information and Communication Technology sector.
Therefore, the ICT sector needs to switch to green computing so that people can use these devices without harming the climate.
Benefits of Green Computing
The tech industry is known for its massive use of electricity which makes it not so eco-friendly. So, switching to green computing is greatly benefiting the sustainability of the tech industry and the environment alike. Here are some of the benefits of sustainable IT.
Reduced Carbon Emission: as mentioned previously, the greenhouse effect is a most substantial drawback of tech, therefore, the most immediate benefit of green computing is reducing carbon emissions. The tech industry can reduce climate change by manufacturing products using more eco-friendly materials and making chipsets that are more energy efficient.
Similarly, reducing the use of non-renewable energy to power these devices can also reduce carbon emissions. Moreover, facilitating the employees to work from home, if you are a business owner can also reduce the carbon footprint by eliminating the need for daily transport and office space.
Low Energy Consumption: As green computing devices are designed for energy efficiency, they can help you lower electricity consumption and electronic waste. For example, cloud computing is more eco-friendly and energy-efficient than the physical servers and hardware of traditional computing.
Reduced Electronic Waste: Sustainable computing is the foundation of the extended lifespan of computing equipment. When the devices are made durable, there is a lesser need for frequent hardware replacement which significantly reduces the e-waste. Also, a more sustainable device means, there is less need to produce new equipment.
Refurbishing of electronic devices also helps in reducing electronic waste. As e-waste exacerbates the solid waste which further increases the release of toxic materials in the landfill, there is a huge risk to health and the ecosystem. So, encouraging proper disposal and recycling of electronic equipment comes in handy. Moreover, using biodegradable materials for manufacturing a device allows the regain of minerals.
Optimization of Resources: on-premises hardware are extensive and require more power supply so green computing encourages the use of cloud computing. This not only reduces the hardware requirement but also reduces the energy consumption enabling a a better allocation of resources.
Technologies like Turbonomic Application Resource Management can help you analyze the resources required to run an application. This ensures the application only uses what it needs which helps in reducing the cost and carbon footprint.
Cloud computing is more efficient and improves the system performance. Therefore, green computing inspires organizations to use cloud computing.
Sustainability: lastly, when you adapt to green computing you are not only innovatively using technology but also helping the plant. As IT professionals, Business owners, and citizens, it is our responsibility to enhance the health of our ecosystem. With green IT, you are not only focused on making smaller and faster devices but more centered on making sustainable devices that reduce emissions. This can be done by using recycled plastic, recycled earth elements, and eco-friendly packaging.
