The bill would not force agencies to use liquid cooling. It would make federal experts study when liquid cooling works best for AI data centers, then send Congress guidance on costs, safety, energy use, and heat reuse.
Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.
Liquid Cooling for AI Act of 2025 is a House bill in committee. The latest recorded action: Referred to the Committee on Energy and Commerce, and in addition to the Committee on Science, Space, and Technology, for a period to be subsequently determined by the Speaker, in each case for consideration of such provisions as fall within the jurisdiction of the committee concerned.
Latest action on H.R. 5332: Referred to the Committee on Energy and Commerce, and in addition to the Committee on Science, Space, and Technology, for a period to be subsequently determined by the Speaker, in each case for consideration of such provisions as fall within the jurisdiction of the committee concerned.
Who this affects: This bill mainly affects federal agencies that build or upgrade large data centers for AI or high-performance computing. It could also matter for companies that design, run, or sell cooling systems for data centers. Researchers, national labs, and local governments may be asked for input. Private data center operators could watch the results, but the bill does not directly order them to change anything.
Why this matters: AI data centers need huge amounts of power, and cooling is a major part of that load. This bill could help Congress and federal agencies understand whether liquid cooling can lower energy use, improve reliability, and support denser computing systems. It could shape future federal data center plans and research funding. Its effect on private companies is less clear and would depend on later choices outside this bill.
You do not have to start with a blank letter. Modern Action turns the bill, your position, and the relevant congressional context into a message you can edit and send. The goal is to make contacting Congress clear, specific, and useful without forcing you to parse bill text or figure out the right office on your own.
