Scaling Renewable Power for Growing Demand
As electricity demand rises worldwide, Amazon has positioned itself as a leading corporate investor in carbon-free energy. Since 2020, the company has been recognized by BloombergNEF as the world’s largest corporate purchaser of renewable energy, including wind and solar. In 2025, it was again cited among the top global buyers while maintaining the largest carbon-free energy portfolio of any corporation.
Amazon says its investments add new sources of clean power directly to shared grids that serve homes, hospitals, and schools. Beyond supplying its own operations, the company argues these projects contribute to broader grid modernization and help stabilize electricity costs for communities.
To date, Amazon has invested billions of dollars in more than 40 gigawatts of carbon-free energy capacity—an amount equivalent to powering over 12.1 million U.S. homes. Its portfolio spans more than 700 projects across 28 countries, including utility-scale solar and wind farms, onsite installations, offshore wind projects in Europe, battery storage facilities, and nuclear agreements.
Regional Investments and Grid Reliability
In Mississippi, Amazon collaborated with Entergy to enable 650 megawatts of new renewable energy tied to its data center expansion. Once operational, the capacity is expected to serve the equivalent of more than 150,000 homes. Entergy is also using investments from large customers, including Amazon, to support a $300 million grid reliability initiative aimed at reducing outage frequency and duration without additional costs to residential customers.
Industry groups note that long-term power purchase agreements from corporations can provide financial certainty for renewable developers. Such commitments, they argue, help scale new generation capacity while improving affordability and reliability.
Advancing Nuclear and Small Modular Reactors
Nuclear energy plays a growing role in Amazon’s strategy. The company is investing in next-generation small modular reactors, or SMRs, designed to provide steady carbon-free power around the clock.
In Washington state, Amazon’s agreement with Energy Northwest supports the development of four advanced SMRs with an initial 320 megawatts of capacity, expandable to 960 megawatts—enough to power roughly 770,000 homes. The project is expected to come online in the early 2030s. Amazon has also committed $500 million to X-Energy to help advance more than 5 gigawatts of nuclear capacity in the United States by 2039.
These projects are projected to generate construction employment and long-term operational roles in local communities.
Battery Storage and Grid Stabilization
Because solar and wind generation depends on weather conditions, Amazon has invested in 11 utility-scale battery storage projects to enhance reliability. At its Baldy Mesa project in California, AI-driven software analyzes billions of data points annually to optimize when energy is stored and released, particularly during peak demand or extreme weather events.
Battery systems aim to extend the availability of carbon-free power and support grid stability during high-usage periods.
Improving Resource Efficiency
Amazon tracks data center water consumption through a Water Usage Effectiveness metric and has set a goal of becoming water positive by 2030. Since 2021, the company reports a 40% improvement in water-use efficiency at its data centers. In 2024, its global WUE averaged 0.15 liters per kilowatt-hour, a 17% improvement from the prior year.
Energy efficiency is also measured through Power Usage Effectiveness. Amazon reports a global PUE of 1.15 in 2024, indicating reduced energy waste compared with typical industry averages.
Broader Operational Efficiency
Beyond energy generation, Amazon has focused on efficiency across fulfillment centers and transportation networks. Its electric delivery fleet includes thousands of vehicles, and facilities increasingly use robotics and AI to minimize wasted energy.
The company frames its carbon-free investments as part of a broader commitment to reach net-zero carbon by 2040 under its Climate Pledge. By expanding renewable, nuclear, and storage capacity while improving operational efficiency, Amazon says it aims to align business growth with long-term community energy needs.
