This is either completely misinformed or disingenuous. Texas just had to freeze all data center development pending audits because their energy supplier (ERCOT) reported that it had received data center load requests totaling 474 gigawatts.

That figure represents ~40% of extant grid capacity for the entire country in just a single state.

edit: I'd also add that historically, power generation has accounted for 4% of all water consumption in Texas. The highest recorded load demand on the ERCOT grid, to date, is ~87.5 GW. Scaling generation capacity by 500% is not possible to achieve within a short-term time frame, but even if it were, the water demand of the additional generation sites would completely drain many critical aquifers and result in skyrocketing water rates for citizens of a state already suffering terrible droughts regularly.
