Watch: The BBC's Shaimaa Khalil is in Arizona to hear from residents about the expansion of data centres.
A year ago, a longtime US senator was not thinking much about data centres. ââ
Now, according to one of his advisers, he is having regular meetings with staff to track their impact and working on new legislation aimed at curbing their rapid expansion across the country.
"This happens sometimes, something starts slow and then it goes fast", the senior policy adviser to the Democratic senator told the BBC. The person spoke on condition of anonymity as they are not permitted to speak to the press.
The 180-degree turn in this senator's attention was driven almost entirely by a growing wave of public backlash that has seen politicians across the country scramble to keep up. Public sentiment has turned against the expansion of data centres, the large warehouses that store processing power needed for internet activity.
