Abstract
For half a century the United States has run a federal program to make machines use less energy. It has never once run a program to make the country use less energy. The Energy Policy and Conservation Act regulates efficiency, which is a ratio, and the statute contains no authority to set a ceiling on aggregate consumption. That distinction was tolerable while the ratio and the total moved together. Artificial intelligence has pulled them apart. Google reports that the energy required to answer a median Gemini text prompt fell by a factor of 33 in twelve months, and reports in the same year that its electricity demand rose 37 percent, the largest annual increase in the company’s history. This Article argues that the gap is structural, and that it appears three times. First, coverage. The gate through which a new product enters the consumer program at 42 U.S.C. § 6292(b)(1)(B) is a fraction with households in the denominator, and the standard-setting gate at § 6295(l)(1) is metered the same way, down to an aggregate figure that is expressly an aggregate of household use. When the Department of Energy proposed in 2013 to cover computer servers, it satisfied the statutory test by computing the energy used by servers in houses. Industry objected that the agency lacked authority over the commercial units, the agency withdrew the determination, and no coverage determination for servers exists today. The same agency, reading a 1978 definition, built the regulatory category of computer room air conditioner out of statutory text that never named it, and now sets mandatory efficiency floors on the machine that cools the data center while setting nothing on the machines inside it. Second, disclosure. Google publishes watt-hours per prompt and withholds the prompt count it used as the divisor, and its chief scientist has said on the record that the company is not comfortable revealing that number. OpenAI has released no model-specific energy data since 2020. The aggregate is therefore not merely unregulated; it is uncomputable by anyone outside the firms. Third, allocation. Compute is financed by risk capital that shareholders bear, and the grid that serves it is financed by a rate base that households cannot leave. The Article makes three contributions. It identifies the household denominator as the mechanism of EPCA’s blindness rather than treating the absence of AI standards as agency inattention. It shows that the withheld denominator in corporate environmental disclosure reproduces the statute’s own epistemic structure, so that the regime and the firm converge on publishing the quotient and suppressing the total. And it locates the resulting cost-allocation question in existing doctrine, where the term of art means what the Seventh Circuit says it means and not what the industry hears.
