As bills to address the energy impact of data centers proliferate and President Donald Trump encourages lawmakers to act, analysts are pointing to a legal minefield.

Analysts say lawmakers — who are looking to mollify constituents worried about electricity prices — face an untested question: Whether the federal government can claim unlimited authority to regulate data centers. Getting the answer wrong could mean complicated legal battles.
