What the Trillion-Dollar AI Expansion Really Means for Our Communities

Understanding data centers, infrastructure growth, and why early awareness matters

A Quiet Shift Happening in Plain Sight

Why this matters now

While underserved communities like Compton continue to deal with housing pressures, unemployment, public safety concerns, and long-standing social and political challenges, a very different kind of transformation is taking place—largely out of public view.

A trillion-dollar expansion of artificial intelligence infrastructure is being built across the country through land-use decisions, utility upgrades, and industrial permitting that rarely receive the same attention as more visible local issues.

This article is presented for educational and informational purposes only. Its aim is not to oppose, slow, or challenge the pace of technological advancement, but to help communities better understand how AI infrastructure is physically and rapidly built, how it tends to grow once introduced, and how early planning decisions can shape long-term outcomes.

This new economy does not arrive with storefronts, job fairs, or ribbon cuttings. It arrives through data centers, electrical substations, transmission corridors, and long-term infrastructure investments designed to serve regional or global markets rather than local neighborhoods. In many cases, once approvals are in place, entire data-center buildings can be designed, permitted, and constructed in six months or less—often faster than most housing developments or retail projects.

Most modern data centers employ very few people relative to their size—typically 5 to 15 staff at smaller sites and 30 to 60 at large facilities, with only the largest multi-building campuses reaching a few hundred total workers. These are mostly specialized technical roles, often filled from outside the local community. As a result, data centers do not significantly impact local job markets and are considered capital-intensive infrastructure rather than job-creating employers.

Because these projects are framed as technical or logistical necessities, they often move forward with limited public awareness, even as they shape the physical landscape for decades. Understanding what this AI expansion looks like on the ground—and how quickly it can take shape—gives communities more room to think ahead rather than react later.

The Trillion-Dollar AI Expansion

Why digital technology needs physical space

AI does not run on software alone. It depends on massive computing power, constant data storage, and electricity that never goes out. To support this, companies are investing enormous sums in facilities designed to operate continuously, at large scale, for decades.

While AI tools feel instant and invisible to users, the infrastructure behind them is permanent. It takes the form of buildings, power connections, cooling systems, and land-use decisions that are often made quietly and are difficult to undo once established.

AI Infrastructure Explained

What the “cloud” really is—and what it is not

The “cloud” is not in the sky. Data does not float overhead.

The cloud is simply a way of describing access to data centers—large industrial buildings filled with computers called servers. These servers store photos, emails, videos, financial records, and increasingly, run AI systems.

Every streamed movie, backed-up phone, or AI interaction depends on physical machines sitting inside one of these buildings. The cloud feels invisible only because most people never see where the work is actually happening.

What AI Data Centers Look Like in Real Life

From idea to concrete and steel

Modern data centers are warehouse-scale buildings. Many are:

• Around 80 feet tall, similar to an eight-story building

• 800 to 1,500 feet long, about two to four football fields end to end

• Operating 24 hours a day, every day

Modern data centers employ very few people relative to their size—typically 5 to 15 staff at smaller sites and 30 to 60 at large facilities, with only the largest multi-building campuses reaching a few hundred total workers.

They rely on:

• Continuous cooling systems to manage heat

• Large ventilation fans that run day and night

• Backup generators kept ready to start within seconds if power fluctuates

Data centers function as 24-hour industrial facilities, not intermittent or daytime-only uses.

Cooling and ventilation systems operate continuously to control server heat, and backup power systems remain energized to allow instant response to grid disturbances. As a result, data centers function as 24-hour industrial facilities, not intermittent or daytime-only uses.

Why Data Centers Often Multiply

How one approval opens the door to many

Data centers rarely arrive one at a time.

Once a data center is approved in a particular area, that decision does more than allow a single project. It signals that the location is considered suitable for this type of infrastructure. Power capacity is confirmed, zoning boundaries are tested, and utility upgrades are justified—making additional projects easier to approve later.

Over time, what begins as one approval can lead to multiple facilities sharing the same electrical corridors, substations, and land-use assumptions. Because each project is usually reviewed on its own, the combined effects—on noise, energy demand, and land use—can accumulate gradually without a clear moment when the full picture is considered.

What AI Infrastructure Uses

Electricity and water—and how they compete with everyday needs

Every large AI data center depends on significant amounts of electricity and water. What varies by location is how directly this water use is experienced. In some regions, cooling water is drawn from the same municipal systems that supply homes, schools, and businesses.

Electricity powers the servers themselves, while water is used to manage the heat those servers produce—either directly at the data center through water-based cooling systems, or indirectly at the power plants that generate the electricity, where cooling is required during power production.

The rapid build-out of AI data centers require continuous, high power rather than occasional spikes.

The issue is not whether water is required, but how much of a community’s water and power capacity is allocated to machines versus everyday human needs. Because data centers operate continuously, their demand for both resources is continuous as well. At scale, this shifts electricity and water from background utilities into long-term planning questions, particularly in communities already managing limited infrastructure capacity.

Where AI Infrastructure Gets Built

Why companies choose certain neighborhoods

AI facilities are designed to last for decades. Companies place them in areas where they expect stability—predictable land-use rules, reliable utility service, and consistent development patterns.

That’s why population and development trends matter, even though AI projects are not about housing. Areas with established infrastructure and predictable zoning tend to attract long-term investment.

This does not mean AI development causes people to move, or that housing trends control technology decisions. It simply means both tend to respond to the same underlying conditions.

California’s Growing Power Demands

A typical U.S. household uses about 1–1.5 kilowatts of electricity on average. A single large data center often draws 50–100 megawatts continuously, equal to the power use of roughly 30,000 to 70,000 homes running 24/7. Unlike households though, data centers consume steady, nonstop power, giving them an outsized impact on the electric grid.

What this means locally

In California, planners are preparing for increased electricity demand associated with large computing facilities. Meeting that demand involves decisions about where to strengthen the grid and where new infrastructure can be placed.

Because AI infrastructure can be approved and built more quickly than many other forms of development, these decisions can move forward before broader community conversations fully take shape.

What This Means for Compton

Why early decisions matter

For Compton, the issue is not any single project. It is the direction set by early approvals.

The city already hosts major regional infrastructure alongside residential neighborhoods. When new high-intensity electrical uses are introduced, they can establish precedents that make similar projects easier to approve in the future.

Over time, these incremental decisions shape land use, noise levels, and environmental conditions. Once established, those patterns are difficult to change.

One Big Picture

Across the United States, there is growing discussion that the nation’s power supply may need to double or more in the coming decades to keep the system reliable. This concern is driven by several major sources of electricity demand rising at the same time: the rapid build-out of AI data centers that require continuous, high power rather than occasional spikes; the electrification of buildings; the shift toward electric vehicles; and the growth of energy-intensive manufacturing such as chip and battery plants. At the same time, older power plants are retiring and grid expansion is slow, leading planners to conclude that existing generation and transmission capacity will not be sufficient without a substantial increase in overall power supply.

Why awareness matters now

The expansion of AI, the growth of its supporting infrastructure, and local development patterns are not separate stories. They unfold through routine decisions that add up—often faster than housing or retail development, and with longer-lasting effects.

For communities like Compton, the key question is not whether AI will continue to advance—it will—but how and where the physical systems behind it are integrated into everyday neighborhoods.

Understanding what the trillion-dollar AI expansion actually looks like on the ground allows communities to engage earlier, ask better questions, and think long-term—without opposing innovation, and without being caught off guard by its physical footprint.
