Energy use

Negative impact

As of 2017, it is estimated that two billion computer systems are in use in the world. These systems require energy. While one individual system may not need much energy to operate, two billion systems require vast amounts of electricity.

Positive impact

Although computer systems use energy, they can be used to create intelligent systems that control and limit the energy use of other devices. Intelligent systems include:

  • Heating systems
  • Traffic control
  • Car management systems
