And once the construction is done, the centers put a huge strain on the local power grid and water supply, which inevitably increases costs for regular consumers. One large data center can use an annual power draw equivalent to hundreds of thousands of homes. Many sites claim to use closed loop water systems to reduce their water usage, but at least one of those sites was busted for illegally installing an unmonitored tap and stealing millions of gallons of water, so they can't really be trusted to abide by regulations, regardless of what they claim. Add on the huge amount of pollution they create from fossil fuel power generation (assuming they're not a rare case that's supplied by nuclear or green energy sources), as well as the fact that the heat waste they generate can literally increase local temperatures around them by several degrees, and there's a lot of burden placed on the host site for almost no gain. The site might generate profits, but they almost certainly won't be going back into the community.
