Green Computing, also known as Green IT, in the context of cloud computing, refers to the conscious use of cloud-based resources in a manner that reduces their environmental impact.

This can include optimizing applications for energy efficiency, using renewable energy to power data centers, and recycling or properly disposing of old hardware. Green computing is a critical aspect of sustainable IT operations, and it's increasingly becoming a priority for businesses of all sizes due to its potential to reduce costs and carbon footprints.

• Green computing can significantly reduce energy consumption, leading to cost savings.
• It helps companies reduce their carbon footprint and promote sustainability.

‍

Green Computing works by implementing practices that reduce energy consumption and environmental impact. These practices can include:

• Energy-efficient programming: Designing software and applications to use less CPU power.
• Virtualization: Using virtual machines can reduce the number of physical servers required, thereby saving energy.
• Proper disposal: Recycling or properly disposing of old hardware to reduce waste.

A company, EcoTech, decides to reduce its environmental impact by adopting green computing practices. They optimize their applications to be more energy-efficient, use virtual machines to reduce their physical server count, and switch to a cloud provider that uses renewable energy to power their data centers. This not only reduces EcoTech's carbon footprint but also leads to significant cost savings in energy consumption.

• By adopting green computing practices, EcoTech is able to reduce its operational costs and contribute to environmental sustainability.
• The use of renewable energy sources for their data centers further enhances their sustainability efforts and sets a positive example for other businesses in their industry.
