How much electricity does Google use?

Google reported 32.2 million MWh of company-wide electricity consumption in 2024, about 96% of it in data centers, per its 2025 Environmental Report.

How much electricity does Microsoft use?

Microsoft reported 37.0 million MWh of electricity in fiscal year 2025 (ending June 30, 2025), per its 2026 Environmental Data Fact Sheet.

How Much Electricity Does Big Tech Use?

Company-reported figures · data as of 2025-10-31 · last verified 2026-08-15 · page updated August 15, 2026

In their own sustainability reports, Google reported 32.2 million MWh of company-wide electricity consumption for 2024 (96% of it in data centers), Microsoft 37.0 million MWh for its fiscal year ending June 2025, and Meta 18.4 million MWh for 2024. Each roughly doubled or more in five years. Apple reports 3.8 million MWh for its corporate facilities, a different and much smaller boundary. Amazon discloses no absolute electricity total at all. These are company-reported, unaudited figures with different reporting boundaries, so this page presents each company against its own history rather than ranking them against each other.

Google and Meta, calendar years

Google and Meta report the same boundary (company-wide operational electricity, data centers plus offices, calendar year), so they can share a chart:

Google Meta company-wide electricity, GWh

Sources: Google Environmental Report 2025 (appendix, PDF p. 107); Meta 2025 Environmental Data Index (PDF p. 6). Both companies' figures include their data centers, which account for 96% (Google) and 98% (Meta) of the totals.

Microsoft, fiscal years

Microsoft electricity consumption by fiscal year (ends June 30), GWh

How to read these numbers

They are company-reported and unaudited. Some carry third-party limited assurance; none are regulatory filings. Restatements between report editions happen; each table above comes from the single most recent edition so the history within it is internally consistent.
Boundaries differ, so rankings mislead. Apple's figure covers corporate facilities only and excludes its contract manufacturing, which dominates its actual energy footprint. Amazon's absence is a disclosure choice, not zero consumption.
Fiscal years differ. Microsoft's year ends June 30 and Apple's in late September; Google and Meta report calendar years.
Scale check: the four disclosed totals for 2024-ish periods sum to roughly 91 million MWh, against LBNL's estimate of 192 million MWh for all US data centers in 2024. The figures are not directly comparable (company totals are global and include offices), but they show these four companies alone operate at the scale of a large fraction of the US data-center fleet.
