3.8 Ethical, legal and environmental impacts

• Computers consume energy both during operation (when they are switched on) and standby mode (when they are not being used).
• Energy consumption by computers has increased significantly over time due to their widespread use.
• The impact on the environment is an important consideration when designing computer systems.
• The carbon footprint is the total amount of greenhouse gases emitted by an activity or product.
• Energy consumption can be reduced through power management techniques such as turning off unused devices, using sleep modes, and reducing screen brightness.
• Power-efficient electronic design incorporates low-power components into computer systems to reduce overall energy usage.
• The carbon footprint is the total amount of greenhouse gases emitted throughout the life cycle of a product or service.
