Summary 📝

Computer science affects the environment in many ways, both positively and negatively. Making and using digital devices uses up natural resources and energy. Data centres need huge amounts of electricity to keep running and stay cool, which can increase carbon emissions. 

Old computers often end up as e-waste, which is harmful if not recycled properly. However, computer science can also help the environment – for example, by creating systems that reduce paper use or support renewable energy. It’s important that we think carefully about how technology is made, used, and disposed of, so that we protect the planet for the future. 

Understanding these environmental effects helps us make better choices in designing and using technology.

Key learning Points 📌

• Making computers uses raw materials and energy.

• Mining for metals like gold and lithium harms the environment.

• Using computers adds to electricity use and carbon emissions.

• Data centres need a lot of energy and cooling systems.

• Electronic waste (e-waste) is a big problem – it must be recycled properly.

• Some parts of old computers are toxic to people and nature.

• Computers can reduce environmental impact by saving paper and supporting remote working.

• Smart technologies (like smart meters) can help save energy.

• Cloud computing allows shared resources but still uses large amounts of power.

• Responsible design and disposal of technology is important.
