U.S. data centers consumed 183 terawatt-hours of electricity in 2024, a figure driven significantly by the surge in AI. This massive power consumption problem is forcing companies like Okta to expand renewable energy purchases.
AI adoption is skyrocketing due to its perceived benefits, but its underlying energy consumption rapidly escalates. This poses a significant environmental challenge.
As AI integration deepens across industries, companies will increasingly face pressure to offset their energy usage. Sustainable AI practices become a critical component of corporate responsibility and operational strategy.
The Escalating Energy Demands of Data Centers
- Electricity consumption from data centres is estimated to amount to around 415 terawatt hours (TWh), according to the IEA.
- Data centres account for approximately 1.5% of global electricity consumption, according to the IEA (data from before 2025).
These figures aren't just statistics; they reveal data centers, the very backbone of our AI future, are already guzzling a significant chunk of global power. Ignoring their sustainability is no longer an option.
Okta's Proactive Stance on AI Sustainability
Okta adopted a sustainable strategy in April to manage the artificial intelligence software used by its employees, according to Trellis Group. The company expanded its purchases of renewable energy certificates.
These certificates cover the additional energy needed to run the top two third-party AI tools used by the company. Okta's move isn't just good PR; it's a blueprint. By directly offsetting the energy demands of their AI tools, they're showing other companies how to put their money where their mouth is. The question is, who's next?
A Rapidly Growing Footprint: US Data Center Consumption
The U.S. isn't just participating in the AI boom; it's leading the charge in energy consumption. At 183 TWh in 2024, according to Pew Research, we're gobbling over 44% of the global data center electricity. That's not just a statistic; it's a glaring red flag.
