The AI power demand accounting problem: what's missing from the renewable commitment announcements

Every major hyperscaler is making 100% renewable energy commitments alongside AI infrastructure announcements. I want to be specific about what those commitments do and don't actually cover. What they typically mean: matching electricity consumption with renewable energy certificates or direct procurement contracts on an annual basis. This drives real new renewable development. What they don't address: time-matching. If an AI facility draws power at 2am when solar isn't generating and wind is calm, the marginal electricity is from whatever is on the grid at that moment — often natural gas. Annual matching doesn't change this. The dispatchability problem is where the AI power conversation gets hard. These facilities need firm power, continuously. Renewables plus storage can eventually provide that, but the storage deployment pace is currently far behind the demand growth curve. Microsoft's Three Mile Island contract is the most honest response I've seen: buying firm, carbon-free power rather than REC matching. It's more expensive and harder to scale, but it's the actual solution to the time-matching problem. How are others thinking about the gap between annual renewable matching and the actual grid carbon intensity of 24/7 AI compute?
