Data centers power the cloud, streaming, and everyday digital services, but electricity demand is rising as capacity expands. Efficiency gains help, yet total power use depends on growth rates, electricity mixes, and local policy. This page walks you through global consumption trends and where hyperscale growth is concentrated, then connects those patterns to carbon outcomes and accounting boundaries (Scope 1–3).
