How much electricity do data centers consume globally?

Data centers consume approximately 1.5% of global electricity as of 2026, roughly 300-350 TWh per year. This is projected to reach 3-4% by 2030 due to AI workload growth. However, data centers account for only 0.5% of global carbon emissions because many hyperscalers use 90-100% renewable energy.

Which hyperscaler has the best renewable energy record?

Google, Microsoft, and Meta have all achieved or committed to 100% renewable energy matching for their global operations. Google pioneered 24/7 carbon-free energy matching and targets 100% by 2030. AWS has reached approximately 90% renewable and is accelerating toward 100%. All major hyperscalers are also investing in next-generation clean energy including nuclear and geothermal.

How does cooling type affect water usage in data centers?

Air-cooled data centers use essentially 0 liters of water per kWh for cooling. Evaporative cooling systems consume approximately 1.8 L/kWh, making them the most water-intensive option. Hybrid systems that combine air and evaporative cooling achieve roughly 0.5 L/kWh. Direct liquid cooling can reduce water usage to near zero while handling much higher heat densities.
