Energy and water: the hidden cost of AI

When you type a question to an artificial intelligence assistant and receive an answer in seconds, it all seems ethereal, almost magical. But behind that magic is a very physical reality: enormous data centers running 24 hours a day. During 2024, the accelerated growth of AI put the spotlight on something often overlooked: those facilities consume significant amounts of electricity to operate and water to cool their equipment.

We’re not saying this to scare anyone or to ask you to stop using these tools. On the contrary: AI, well applied, can transform the operation of a Mexican small business. We say it because understanding where that hidden cost comes from helps you make better decisions, use technology wisely, and distinguish between what adds real value and what just consumes resources without giving anything back.

Why AI has a physical cost

Every AI model lives in a data center: thousands of servers working in parallel. Training a large model requires an enormous amount of energy, and although you don’t train anything when you use it, each query also spends electricity. On top of that comes water: many of these facilities are cooled with systems that evaporate water to dissipate heat.

For a small business, the lesson isn’t technical but strategic. AI isn’t free or infinite, even if the cost doesn’t always show up on your bill. Every process you automate has consumption behind it, and that invites you to use it with the same logic with which you manage any other resource in your business: with intention and by measuring results.

Using AI wisely, not as a fad

At Normandia Web we believe technology should solve concrete problems, not be added just to follow the trend. Applying AI to everything, without a clear objective, doesn’t just waste the planet’s resources: it also wastes your money and your time. The right question is never “can I use AI here?” but “does this give me a measurable improvement that justifies using it?”

Some signs that you’re using AI responsibly and profitably:

• You have a clear objective. You know which process you want to improve and how you’ll measure the result, whether in time saved or better decisions.
• You start narrow. You first automate a specific task, validate it, and then scale it, instead of trying to transform everything at once.
• You choose the right-sized tool. Not everything requires the biggest, most expensive model; many tasks are solved with lighter, more efficient solutions.
• You keep your data, processes, and history. AI integrates with your existing operation instead of forcing you to start from scratch.

The most sustainable AI is the one that solves a real problem; the one used as a fad only consumes resources without returning value.

Custom software: efficiency by design

When a solution is built to the measure of your business, it focuses on what you truly need. That not only makes it more useful, it also makes it more efficient: it processes only what’s necessary, relies on AI only where it adds value, and avoids the waste of running heavy models for tasks that don’t warrant it.

That efficiency by design has a double benefit. On one hand it reduces resource consumption, which is a concrete and honest form of sustainability. On the other, it translates into lower costs and a system that responds better to your day-to-day. Doing things responsibly and doing them profitably is, very often, the same decision.

How to take advantage of AI without waste

If you want to take advantage of AI without falling into waste, we recommend moving forward with order:

• Identify a concrete problem. Choose a repetitive task or a process that takes your time, and define what result you expect.
• Start small and measurable. Test in a narrow area, measure the real impact, and decide with data whether it’s worth scaling.
• Prioritize integration. Look for solutions that connect with your current systems and respect your information and history.
• Ask for honest advice. A good technology partner will tell you when AI truly adds value and when there’s a simpler, cheaper path.

The energy and water consumption of data centers isn’t a reason to stop, but an invitation to use technology thoughtfully. If you want to give AI that use in your business, at Normandia Web we can design it with you: custom solutions that leverage AI only where it truly matters, so your investment pays off to the fullest without spending extra resources. Let’s talk about that first process you’d like to improve.
