Wait for the Wind

Most agentic workloads don't need to run right now.

A nightly report. A background document analysis. A batch embedding run kicked off while the user's browser was still open. These tasks have deadlines measured in hours or days, not milliseconds. And yet by default they run immediately, consuming electricity at whatever carbon intensity the grid happens to carry that minute, with no thought given to whether cleaner power will be available in two hours.

This is a solvable problem. It has been solved, at hyperscale, for years.

Google began deferring non-urgent batch workloads to lower-carbon grid periods in 2020, starting with video transcoding and image processing at YouTube scale. Microsoft made Windows Update carbon-aware in 2022. Xbox followed in 2023, holding overnight updates for lower-carbon windows. An open-source toolkit, the Carbon Aware SDK, now codified as ISO/IEC 21031:2024, lets any scheduler query real-time carbon intensity from WattTime or ElectricityMaps and hold a job until the grid cleans up. The technology exists. The standards exist. What doesn't exist is any requirement to use them.

The numbers

Here is where the caveats start, because the numbers in this space are genuinely messy. Global data centre electricity consumption hit around 415 TWh in 2024. The IEA projects 945 TWh by 2030, more than double, with AI's share of that demand expected to grow from roughly 5–15% today to 35–50% by 2030. Carbon emissions from AI systems could reach 80 million tonnes of CO2-equivalent in 2025, with water consumption from AI infrastructure potentially exceeding 6 billion cubic metres by 2027, more than Denmark uses in a year.

The methodology behind any single figure is contestable and the range of estimates is wide. What isn't contested is the direction. The compute footprint of agentic AI is expanding fast, and every additional GW of demand that comes online without corresponding clean generation creates pressure that grids absorb somehow, usually by running the plants already on standby.

The grid argument

The strongest case for carbon scheduling isn't the direct carbon reduction argument. It's the grid stability argument, and it's more durable because it doesn't depend on resolving contested accounting questions.

Carbon intensity on any given grid fluctuates throughout the day — it's lower when solar and wind are generating, higher when demand peaks and gas plants ramp up. That gap between the daily low and the daily high is the window carbon scheduling exploits.

Peaker plants, the gas turbines that sit idle most of the year and spin up only during demand spikes, are among the most carbon-intensive assets on any grid. Utilities build them for margins. Every demand spike that can be smoothed reduces the call on peakers.

Research from Duke University found that if AI and cloud data centre operators accepted curtailments of just 0.25 to 1 percent of annual hours, somewhere between 22 and 88 hours a year, grid operators could reliably absorb 76 to 126 GW of new AI demand without building corresponding generation capacity. That's not a rounding error. 126 GW is a lot of plant you don't have to build.

This isn't theoretical. During summer 2024, demand response events in New England provided over 154,000 kWh of reductions and avoided over 44,000 kg of CO2 by preventing peaker dispatch. FERC, NERC, and the DOE all moved in 2025 to address AI's grid impact more directly. Demand response markets that pay large consumers to curtail during stress events are mature and well-established. Industrial loads have participated in them for decades. AI compute mostly doesn't.

What we're calling for

The UAW has one foundational principle on compute: sufficiency. Enough resources to do the work. No more than the work requires. Carbon scheduling is that principle applied to energy.

Deferrable agentic workloads should be carbon-aware by default. Where a task has deadline flexibility exceeding one hour, operators should demonstrate carbon-aware scheduling or document why they haven't. Any team using the Carbon Aware SDK can implement this in an afternoon. The technical barrier is zero.

Deferability should also be a declared attribute at the point of deployment. Agentic frameworks should require operators to classify each workflow as latency-critical or deferrable. That classification makes scheduling auditable, and it forces a design question too few operators are asking: does this actually need to run now, or does it just happen to?

Operators at meaningful scale should participate in grid demand response programmes. Carbon scheduling for environmental reasons and demand response for grid stability are the same action with different paperwork. Large data centres should be registered participants in their regional markets. Industrial loads have done this for decades.

What this doesn't fix

Worth being direct about the limits here, because the counterarguments are real.

Carbon scheduling moves a workload from a coal-heavy period to a wind-heavy one. It doesn't remove carbon from the atmosphere. If coal plants baseload regardless of when you run your jobs, the marginal impact of your scheduling choices depends heavily on your region. A 2024 EuroSys study found that achievable savings from temporal and spatial workload shifting are significantly smaller than theoretical upper bounds — many regions with low average carbon intensity have low variance, meaning there's no dirty peak to avoid.

There's also an accounting mismatch that nobody has cleanly solved. GHG Protocol Scope 2 rules require average emission factors, not marginal ones. A company can invest seriously in carbon-aware scheduling, genuinely shifting compute to cleaner periods, and see no improvement in its officially reported figures. This is a design flaw in the standard, not a reason to stop scheduling, but it does mean that the companies doing this work get no credit for it under current disclosure rules. The UAW is calling for reporting frameworks to catch up.

None of this makes the effort pointless. Imperfect beats nothing, and the grid stability benefits are verifiable on their own terms regardless of how Scope 2 accounting resolves.

The ask

Most agentic workloads can wait a few hours for clean power. Most do not. That gap isn't technical. It's a default that nobody has bothered to change.

The Carbon Aware SDK is open-source and production-ready. WattTime and ElectricityMaps publish real-time carbon intensity data with 24-hour forecasts. ISO/IEC 21031:2024 gives you a standardised way to measure what your scheduling choices actually achieve. None of this requires a regulator.

The UAW will track which operators implement carbon-aware scheduling for agentic workloads, which participate in demand response programmes, and which do neither while publishing net-zero commitments.

An agent that can wait will wait. An operator who says it can't is making a choice, not reporting a constraint.
