Electricity costs have skyrocketed as more data centers join grids without suitable additions in energy sources.</p><p>In an attempt to combat this, President Donald Trump has rolled back regulations on fossil-fuel burning power stations, with multiple data centers being built with on-site natural gas turbine electricity generation. This has caused a string of issues with <a href="https://www.techradar.com/pro/dizziness-nausea-vertigo-and-sleep-disruption-the-undetectable-hum-of-ai-data-centers-is-making-local-residents-sick" target="_blank">local residents complaining of sickness caused by infra-sound</a>, and deafening noise levels similar to that of an international airport.</p><p>Funding and incentives for renewable wind and solar sources have also been scrapped by Trump, which ironically are some of the cheapest energy sources in the US. This has compounded consumer electricity price rises, acting as a catalyst for data center opposition in the US. <a href="https://www.techradar.com/pro/if-ai-is-to-help-build-a-better-future-it-must-be-honest-about-what-it-costs-us-now-un-urges-ai-giants-to-reveal-full-extent-of-environmental-damage" target="_blank">AI companies have been urged by the UN to disclose the full environmental damage of the technology</a>.</p><p>Additionally, a study by <a href="https://asia.nikkei.com/business/technology/five-us-tech-giants-hidden-debts-soar-to-1.65tn-on-opaque-ai-funding" target="_blank" rel="nofollow"><em>Nikkei</em></a> has found that numerous big tech firms looking to expand data center capacity have almost $1.65 trillion in ‘hidden’ debt, where contracts are signed between subsidiary companies and data center operators.
