Amazon says it now runs on 100% clean power. Employees say it's more like 22%

68% of Amazon's Renewable Energy Credits (RECs) are unbundled, not funding new renewables but crediting existing projects, as per employee research.

Amazon's data centers may contribute to fossil fuel grid expansions as they grow, with a representative highlighting Dominion Energy's non-renewable expansion in Virginia.

Amazon's REC purchases being location-independent and not time-specific don't necessarily support the grids powering their data centers, unlike Google's more targeted approach.
