Understanding Environmental Issues for Computer Systems

Energy Consumption of Computer Systems

Computer systems use energy and thus contribute to overall energy consumption.
Energy use is largely linked to the performance of the system: higher performance often means more energy consumption.
Computers use energy while they’re running, but also when they’re left on standby.
Servers in data centres, which run 24/7, use a significant amount of energy.
Due to the massive consumption of energy globally, designing energy-efficient computer systems has become a major concern.

Electronic waste or E-waste consists of discarded electronic or electrical devices, including computer systems.
Computer components, such as monitors, CPUs, keyboards, and mice, are all part of e-waste when they reach the end of their life.
E-waste can contain toxic substances such as mercury and lead, which can cause harm to the environment and health risks to humans if not disposed of properly.
Often, e-waste is exported to developing countries where it can be improperly disposed of, leading to environmental and health issues.
Recycling e-waste is an important part of managing it, parts can often be recovered and reused.

The manufacturing process of computer components consumes resources such as metals and plastic.
Rare earth metals used in creating components are depleting at a fast pace due to high demand.
Mining of these metals causes water and soil pollution and deforestation.
Production also involves chemical processes that can release harmful compounds into the environment.

Green IT refers to environmentally friendly computing or IT practices.
It can involve strategies such as recycling computer components, optimising systems for energy efficiency, using renewable energy sources, and reducing the use of harmful substances in manufacturing.
Energy Star certification signifies that a computer or computer component is designed to be energy-efficient.
Adopting Green IT strategies is not only beneficial to the environment, but can also reduce costs over time.
