Internet and its usages

• Made up of wires traversing oceans, satellites and cell-phone towers

• About 3.6 billion people have access to the internet

• Used for information, entertainment, business and more..

Energy consumed by the internet :

• 30 billion devices connected to the internet

• 200 to 400 Terawatt-hours per year

• charging, manufacturing devices and electronic components consume energy

laptop: ordinateur portable

manufacturing: fabrication

Data centers :

fossil fuels: combustibles fossiles

higher density: densité plus élevée

• Groups of computers that make up a system’s back end

• 1 or 2% of the world’s total electricity from burning fossil fuels

• Number of data centers depending on region and companies

Environmental consequences :

rely heavily: dépendent fortement

• one billion tons of greenhouse gases annually

• companies rely heavily on the internet for their operations

Solutions :

• energy-efficient manufacturing processes and recycling materials for building computers.
