Key components of green computing:

  • Energy efficiency. Designing, manufacturing, and using IT systems to consume less electrical power. Examples include Energy Star-rated devices, energy-efficient power supplies, and power-saving software mechanisms.
  • Resource reduction. Minimizing the use of hazardous materials, recycling, and non-renewable resources.
  • Virtualization. This allows multiple operating systems to run on a single physical server. It reduces the number of servers and the energy consumption of data centers.
  • Cloud computing. Shared resources in central data centers is more energy efficient than using individual servers or data centers.
  • Data center design. Efficient cooling systems, better server arrangements, and power distribution reduces power consumption.
  • E-waste management. Proper disposal and recycling of electronic waste. This ensures that hazardous components like heavy metals do not contaminate the environment.
  • Sustainable IT procurement. Purchasing systems based on environmental impact. For example, buying energy-efficient devices or those with minimal hazardous components.
  • Telecommuting and virtual collaboration. Reducing the need for physical travel and carbon footprint.
  • Software efficiency. Creating software solutions that use resources in the most effective manner.
  • Promotion of renewable energy sources. Using renewable energy for powering IT infrastructure.
