AI technologies rely on data centers, which are large buildings filled with servers that provide the computer power AI needs. These data centers use a lot of electricity and water. They also produce greenhouse gases. As more people use AI, especially in healthcare, the environmental impact is growing.
By 2030, the amount of electricity used by data centers worldwide is expected to more than double. It could go from about 415 terawatt-hours in 2024 to around 945 terawatt-hours. This increase is mostly because AI work is growing by about 15% each year. In the U.S., AI servers might use between 200 and 300 billion gallons of water every year by 2030, mainly to keep the servers cool. This large water use is a problem in places where water is already scarce, and many hospitals are in these areas.
AI infrastructure also causes carbon emissions. Estimates say AI servers in the U.S. may emit 24 to 44 million metric tons of CO₂ each year by 2030. This depends a lot on how the electricity is made. Since data centers already use about 1% of the world’s electricity, and some U.S. states are seeing big increases, it is important to address this environmental problem.
Making AI hardware adds to this impact. For example, building a 2-kilogram computer often needs about 800 kilograms of raw materials. Some materials, like rare earth elements, are mined in ways that hurt the environment. This causes resource loss and pollution.
One good way to lower AI’s environmental impact is to make hardware more efficient. More efficient servers use less electricity and create less heat. This means less energy is needed to cool them.
Cooling systems use a big part of the energy and water in data centers. Old air conditioning uses a lot of electricity and water. New methods like liquid cooling and immersion cooling can cut energy use by 40 to 50% and water use by 20 to 90%.
For example, Meta’s StatePoint liquid cooling system uses water-based cooling to reduce energy and water use. Microsoft’s Project Natick puts data centers underwater to use the ocean’s cooler temperatures. This lowers the energy needed for cooling and makes the system more reliable.
Hospitals using AI services like Simbo AI should ask their vendors about how efficient their hardware is. Choosing AI systems with advanced cooling can save energy and reduce carbon emissions. This is important as healthcare tries to be more environmentally friendly.
Besides cooling, improving AI software can help too. Making AI code require less computing means servers use less electricity. This reduces the environmental impact directly.
Using renewable energy instead of fossil fuels is another way to reduce AI’s environmental impact. Data centers powered by coal or natural gas create a lot of greenhouse gases. People are interested in using solar panels, wind turbines, and energy storage systems to provide clean energy.
Microgrids that combine solar, wind, and batteries give data centers more control over their power and keep systems running during outages. These microgrids can cut emissions by 50 to 80%.
Hospitals and medical centers with high AI use could work with providers who use renewable energy or who have data centers in regions with cleaner electricity. This cooperation helps cut emissions from healthcare operations.
Location makes a difference. Studies show placing data centers in areas with low-carbon electricity and enough water can reduce carbon emissions by almost 49% and water use by around 52%. Healthcare organizations choosing AI vendors should consider where the servers are based. Vendors using renewable energy and good sites help lower environmental harm.
Technology alone cannot fix AI’s environmental issues. Strong rules and policies are needed to guide how AI systems are built and used in the U.S.
More than 190 countries, including the U.S., have some ethical AI guidelines that include environmental concerns. But many plans do not have rules that must be followed. Policymakers are working on standards to measure AI’s environmental impact, require transparent reporting, and encourage energy and water saving technologies.
Federal and state officials should guide AI development to align with climate goals and energy safety. Policies that consider local renewable energy options, grid use, and costs are important. These help reduce dependence on fossil fuels and support energy-efficient hardware.
Hospitals benefit from clear policies because they set industry standards. These rules help AI providers focus on sustainability. Following these rules is becoming expected for legal reasons and social responsibility.
AI tools like Simbo AI, which automate medical office tasks, can improve efficiency and reduce environmental impacts compared to traditional methods.
For example, AI answering services reduce the need for paper, fewer office visits for scheduling, and shorter phone wait times. This lowers energy use in healthcare facilities. Automating tasks helps save time and resources, which supports sustainability.
However, running AI automation also uses energy. Tasks like natural language processing and call routing require constant server work. Designing systems for efficiency helps reduce electricity use for each call or interaction. This connects technology progress with caring for the environment.
Medical IT managers should look for AI solutions that work well and are environmentally responsible. They should pick providers investing in greener hardware and efficient software.
Healthcare in the U.S. faces pressure to reduce environmental harm while providing quality care. AI systems like Simbo AI’s front-office automation help with communication and lowering labor costs, but their environmental effects need attention.
Administrators and IT managers can help by:
Thinking about these points along with medical needs will help healthcare adopt AI without hurting the environment.
The growth of AI in healthcare and other fields will continue. By focusing on hardware efficiency, using renewable energy, and following good policies, the U.S. healthcare system can support AI with less environmental harm. Careful use of AI will help build smarter and more efficient healthcare while cutting energy, water use, and emissions in the years ahead.
AI’s environmental problem includes high energy consumption, electronic waste generation, heavy water usage, and reliance on rare minerals often mined unsustainably, leading to significant greenhouse gas emissions and resource depletion.
AI can detect data patterns, anomalies, and predict outcomes, enhancing environmental monitoring accuracy. It helps track harmful emissions such as methane and assists governments and businesses in making sustainable decisions and improving resource efficiencies.
Data centres consume massive electricity, mostly from fossil fuels, generate electronic waste with hazardous substances, require large water quantities for cooling, and depend on rare earth minerals mined destructively, cumulatively impacting the environment negatively.
Higher-order effects include unintended consequences such as increased greenhouse gas emissions from AI-enabled technologies like self-driving cars and the potential spread of misinformation about environmental issues, undermining public awareness and climate action efforts.
UNEP recommends measuring AI’s impact with standardized methods, enforcing transparency in environmental disclosures, improving algorithm and hardware efficiency, greening data centres with renewables, and integrating AI policies into broader environmental regulations.
AI-related infrastructure may consume up to six times more water than Denmark, a country of 6 million, posing serious concerns given global water scarcity and the lack of access to clean water by many.
A single request to an AI virtual assistant like ChatGPT uses ten times more electricity than a Google Search, illustrating AI’s high energy demands relative to conventional digital activities.
The number of data centres surged from 500,000 in 2012 to 8 million currently, driven largely by AI’s explosion, thereby greatly intensifying energy and resource consumption associated with computing infrastructure.
While data centre impacts are better understood, AI’s broader environmental effects are uncertain due to unpredictable application usage, second-order consequences, and potential behavioral changes driven by AI technologies.
Over 190 countries have non-binding ethical AI recommendations including environment, with some legislation in the EU and USA; however, environmental considerations are often absent in national AI strategies, highlighting a policy gap in sustainable AI governance.
