There are several main ethical concerns regarding generative AI to keep in mind before using any software.
Training generative AI requires a significant amount of power. According to Business Insider, AI servers use anywhere from four to six times as much electricity as cloud servers. The projected demand for AI has led to the growth and construction of new data centers, mainly in rural areas of the United States. In light of environmental concerns about AI and data centers, members of Congress introduced a bill in February 2024 called the Artificial Intelligence Environmental Impacts Act of 2024 to determine and measure the impact the development of AI will have on the environment.
To address the power needs of such data centers, some tech companies are turning to nuclear energy as a climate-friendly solution. In September 2024, Constellation Energy announced it would reopen its nuclear plant at Three Mile Island in 2028 and sell all of the power generated to Microsoft for the following twenty years. Amazon Web Services bought a data center next to the Susquehanna nuclear power plant back in March 2024 with an agreement to purchase power from the plant for the next ten years. Nuclear energy is reliable and carbon-neutral, but expensive and haunted by past disasters, such as those at Three Mile Island in 1979 and Chernobyl in 1986.
Tech companies have also invested in renewable (and non-renewable) energy sources in addition to nuclear energy, but there are still concerns that the amount of power used by these data centers could strain the electric grid and even threaten residential supply in the future.

Another major environmental concern with data centers is the amount of water they require to cool their servers. Because training AI requires so much electricity, it also generates a lot of heat. The temperature of the environment external to data centers also contributes to this issue. Most data centers use air-cooling systems, which are themselves energy-intensive, but when temperatures rise above 85 degrees, a liquid-cooling system is needed. This becomes a particular problem in states like Arizona, where Meta, Microsoft, and Google have all built or are planning to build data centers, and where summer temperatures can reach 115 degrees. As perhaps an omen of future water woes, in June 2023, the Governor of Arizona had to halt new constructions in Phoenix that relied on groundwater because proposed projects would outstrip the projected groundwater supply.
