After a glorious four-year honeymoon, the world is beginning to see the real-life impacts that stem from the now-inescapable artificial intelligence boom.
Silicon Valley CEOs have long promised a glossy future where machines will do all the boring legwork for us, ultimately leading to a more advanced society with fewer problems to solve.
Politicians across the globe have been quick to lap up the narrative about the importance of “winning the AI race” and have now strongarmed in an economy of increasingly expensive data centres to fuel a phenomenon that has almost single-handedly carried the post-Covid US economy.
The numbers are absolutely astonishing.
Amazon, Microsoft, Alphabet and Meta alone are projected to spend roughly US$630 billion (A$879 billion) on data centres and AI chips in 2026 alone.
Consulting firm McKinsey estimates global spending on data centres could hit US$7 trillion (A$9.77 trillion) by 2030, with the US accounting for a massive share.
For most average observers, it’s all just some distant digital contest unfolding behind computer screens.
But the extensive infrastructure needed to power that suddenly all-encompassing future, helmed by a tiny group of billionaires, is very real.
Even in some of the most picturesque, natural parts of the world, communities are beginning to feel the pressure of the reality that’s been placed at their feet.
Enter Lake Tahoe.
One of the most intriguing examples is now unfolding at the popular US tourist destination, where tens of thousands of residents are uncertain over where their electricity will come from after 2027.
Yep.
Utility provider NV Energy recently told the region’s supplier it would stop providing most of its power as demand surges elsewhere in Nevada from hyperscale data centres tied to the AI boom.
To locals, the situation feels totally surreal. The outdoorsy hotspot famous for ski resorts, alpine scenery and summer tourism has suddenly been caught in the middle of a global battle for computing power.
Several hours east of Tahoe, giant technology companies including Google, Microsoft and Apple have expanded aggressively around Reno as northern Nevada transforms into one of America’s fastest-growing data-centre corridors. Forecasts cited by Fortune suggest proposed projects there could add nearly 5900 megawatts of electricity demand by 2033 — enough to rival the output of several major power stations.
NV Energy says the transition away from Tahoe had been planned for years and was not caused solely by data-centre growth.
“It is important to note that the NV Energy’s wholesale agreement with Liberty Utilities was always intended to be temporary and transitional, with a clear timeline and multiple extensions over the years to support Liberty’s long-term planning efforts to secure its own access to energy supply,” the company said in a statement.
“To ensure reliable ongoing service to Lake Tahoe customers, NV Energy agreed in 2025 to continue providing energy service to Liberty’s customers until their transmission access is available and/or until Greenlink is online.”
“NV Energy has provided reliable service to Liberty’s customers in the Lake Tahoe Basin for years and fully intends to continue that commitment while Liberty secures its own transmission access and energy to supply those customers.
“NV Energy has taken proactive steps to ensure there is no service disruption to Liberty customers, now or in the future.”
For locals, the uncertainty has become deeply personal.
“It’s like we don’t exist,” Danielle Hughes, a North Lake Tahoe resident and CEO of nonprofit Tahoe Spark, told Fortune.
Hughes warned smaller communities risk being swallowed by the scale of the AI infrastructure race.
“We’re 49,000 customers. We have no leverage,” she said. “We have no representation. It’s resource extraction.”
As governments and technology firms race to dominate artificial intelligence, it is clear entire regions are quietly being reshaped around the infrastructure required to power it, sometimes with very little say in the specifics.
The transformation is becoming increasingly visible across parts of Europe. In Ireland, data centres now consume more than one-fifth of the country’s electricity supply. Parts of the Netherlands have pushed back against new developments amid fears local grids were becoming overloaded.
In Northern Virginia — the largest data-centre market on earth — residents have increasingly complained about industrial expansion, giant transmission lines and rising pressure on energy systems.
Australia joining the AI party
Sydney and Melbourne are rapidly emerging as major AI and cloud-computing hubs for the Asia-Pacific region. Amazon recently announced plans to invest roughly $20 billion into Australian AI infrastructure over five years, while Microsoft, Google and local operators such as NextDC continue expanding their data-centre footprint.
Most Australians will never see these facilities directly. Many sit hidden inside industrial estates or anonymous outer-suburban buildings. But the scale behind them is still enormous.
The centres operate around the clock, consuming vast amounts of electricity while relying on massive cooling systems to stop servers overheating. Some forecasts suggest Australia’s data-centre capacity could more than double by 2030 as governments and corporations pour money into AI infrastructure.
Energy regulators have acknowledged the strain that growth may place on existing grids in a global market that has already been heavily disrupted this year.
The Australian Energy Market Commission has already warned rapid expansion of large-scale data facilities could create risks to grid stability if demand spikes become too concentrated.
Overseas, researchers estimate global AI systems could consume more water annually than entire countries by next year.
While the extreme power and water requirements has fuelled scepticism and worry, governments see enormous economic potential in becoming regional AI leaders.
Technology companies argue the industry will drive productivity, jobs and investment for decades to come. Several operators are also investing heavily in renewable energy to offset the immense power demands attached to the sector.
But the situation down at Lake Tahoe has still offered an uneasy glimpse into the trade-offs that may emerge as the technology expands further into the physical world.
