The Hidden Climate Cost of AI

Despite bold climate pledges, much of AI’s growth is still tied to fossil fuels. One of the most important, and overlooked, projections comes from energy analysts who estimate that 60% of new data-center demand will be met with fossil fuel generated electricity. That single figure matters more than all the smaller stats: It means AI is directly tied to higher carbon emissions. It means clean energy investments aren’t keeping pace with AI expansion. And it means that unless policy changes, AI will accelerate climate change, not slow it. When we talk about AI being “energy-intensive,” this is what we mean. Not just big numbers, but a trajectory that locks the industry into fossil fuels at the exact moment we should be reducing them.
The most visceral number in this entire conversation may be this: a single data center can use millions of gallons of water a day for cooling. The exact figure varies by region, but the impact is the same. Water that communities need, water that local communities rely on for drinking, farming, and daily life is being diverted to keep servers from overheating. In regions already facing drought or water scarcity, this isn’t just an environmental concern; it’s a matter of environmental justice. And yet, this part of AI’s footprint rarely makes headlines, even though it directly affects ecosystems, agriculture, and people’s access to safe water.
The communities bearing AI’s environmental burden are not the ones reaping its economic benefits. One of the starkest examples is in Boxtown, Memphis, a historically Black neighborhood where Elon Musk’s xAI built a data center powered by 35 methane gas turbines with inadequate pollution controls. Residents report worsening asthma, headaches, and respiratory problems. This isn’t accidental, it’s part of a long pattern: hazardous infrastructure gets placed where political resistance is expected to be lowest.This single example illustrates a much bigger truth: AI’s environmental impact isn’t just about climate harm. It’s about who gets harmed.
Artificial intelligence feels weightless, a cloud-based tool that lives in our phones, browsers, and inboxes. Behind the sleek interfaces is a massive physical footprint that’s growing faster than policy, regulation, or even public understanding. AI isn’t just transforming industries; it’s transforming landscapes, energy grids, and entire communities. And right now, that transformation is taking a toll.
The most powerful AI models today run on “training clusters” that require seven to eight times more energy than traditional computing tasks. That single statistic matters because it captures what’s changed: AI isn’t another app, it’s a whole new category of industrial-scale energy demand.
Data centers powering generative AI are multiplying so quickly that global energy consumption for data infrastructure could reach over 1,000 terawatt-hours by 2026, roughly equivalent to the entire electricity use of countries like Germany or Brazil, putting AI on track to use more electricity than entire countries. But the number isn’t just big. That scale of energy usage is alarming, not just because the numbers are large, but because it translates to real-world impacts in communities already facing limited resources and environmental stress, such as water shortages, air pollution, and grid instability.
Tech companies love to talk about efficiency gains, such as better chips, smarter cooling systems, and improved data center designs, but the math tells a different story. Even as individual AI systems become more efficient, the overall demand for generative AI is growing exponentially. Every new model, every surge in users, every additional application adds energy and water needs faster than efficiency improvements can keep up. In other words, the problem isn’t that AI itself is becoming more powerful, it’s that we’re scaling AI use far faster than we’re building the sustainable infrastructure needed to support it. Without careful planning, energy grids, water supplies, and local ecosystems will continue to feel the strain.
Addressing AI’s environmental impact isn’t hopeless, but it requires a deliberate shift in how we build and regulate the technology. Cities and states need to implement stricter oversight on where data centers are placed so that marginalized communities aren’t used as environmental sacrifice zones. AI companies should be required to publicly report their carbon emissions, water usage, and energy sources instead of offering vague sustainability claims.
At the policy level, AI expansion should be tied directly to the availability of renewable energy, preventing companies from defaulting to fossil fuels whenever demand spikes. At the same time, federal and state governments must invest in upgraded grid infrastructure that can support technological growth without worsening climate change.
Finally, community voices, especially Black, Brown, rural, and low-income residents disproportionately impacted by data-center pollution, need to be centered in every stage of decision-making. Too often, tech companies prioritize profit over people, dumping environmental and health costs onto vulnerable communities. The solution isn’t simply “cleaner technology”; it’s reevaluating whether and how we build AI at all, and ensuring that its deployment never comes at the expense of people or the planet.
AI doesn’t have to be destructive, but we can’t keep pretending its infrastructure is invisible. Most people only see the sleek interface, the chatbot, the app, the recommendation engine, without realizing the environmental toll hiding behind the screen. Gigantic data centers burn through guzzle electricity and guzzle millions of gallons of water, fossil fuel plants are fired up to meet skyrocketing demand, and communities near these facilities face polluted air, drained water supplies, and land stripped for massive server farms. This is not some abstract cost. It’s real, and it hits the most vulnerable hardest. If AI continues to be built on this low-road, high-impact model, we’re choosing a high-tech world powered by environmental exploitation. That’s a price none of us should be willing to pay.
