The list of reasons for datacenter moratoriums below was generated through an online search – note the enumerated hyperlinked sources in brackets.
Several considerations are conspicuously omitted in this summary, suggesting that these issues should be added to actions calling for moratoriums.
- Thermal pollution – substantially raising air and ground temperatures that impose higher energy costs for air conditioning as well as harms to public health and the environment.
- Threats to property value for homeowners and small businesses located in areas surrounding datacenters.
- Worsening already harmful climate change through added emission of heat-trapping gases when dirty energy is used to generate the massive power needed for datacenters.

Primary reasons communities and lawmakers issue data center moratoriums:
1. Grid Capacity and Surging Energy Costs
- Strain on local utilities: Hyperscale data centers require immense amounts of electricity, often threatening the stability of local power grids. [1, 2]
- Rising consumer utility bills: To accommodate the sudden spike in energy demand, utility companies must build new transmission lines and generation facilities. The cost of this infrastructure expansion is frequently passed along to everyday residential ratepayers. [1, 2]
- Undermining clean energy goals: The rapid timeline of data center buildouts has forced some utilities to delay the retirement of fossil-fuel plants or permitted data centers to utilize "behind-the-meter" fossil-fuel generators to guarantee constant power. [1, 2]
2. Water Scarcity and Cooling Demands
- Enormous consumption rates: Traditional data centers require millions of gallons of water daily for evaporative cooling systems.
- Aquifer depletion: In drought-prone areas, local governments use moratoriums to evaluate whether data center consumption will deplete municipal drinking water supplies or harm local agricultural infrastructure. [1, 2, 3]
3. Noise Pollution and Quality of Life
- Continuous low-frequency drone: The massive cooling towers and industrial backup generators required for these facilities operate 24/7.
- Health impacts: Nearby residents have increasingly reported sleep disruption, chronic headaches, and anxiety caused by industrial noise that can reach up to 70–105 decibels, prompting local city councils to pause approvals until strict acoustic setbacks can be codified. [1]
4. Poor Economic Return-on-Investment
- Low job creation: While data centers generate significant short-term construction employment, a completed facility typically only requires 20 to 50 permanent staff members to operate. [1]
- Disproportionate tax breaks: Many jurisdictions are reconsidering the steep, long-term public tax incentives historically used to attract tech giants, realizing the local tax revenue generated does not offset the strain placed on public infrastructure. [1]
5. Institutional Capacity Gaps
- Outdated zoning codes: Many local planning departments are structured to handle light industrial or standard commercial zoning. They lack the specialized engineering and environmental staff to properly evaluate 50+ megawatt compute hubs. Moratoriums allow cities time to rewrite modern industrial-policy rules. [1, 2]
