In 2025, the United States power demand needs are at their highest levels ever. This can be attributed to the fact that just about everything in modern life requires being plugged into an outlet at some point. Whether it’s charging your phone, using your laundry machines, or even using the air conditioner, power is always required. However, the wealth of technological innovation and plethora of devices that require an electrical connection are on the verge of outpacing our current power output. In fact, its power demand will be 50% in just 25 years from now.
So how exactly is energy being used across the nation? As of 2023, transportation like cars, aircrafts, and ships accounted for the largest share of electrical demand at 37%. Right behind that was the power used for industrial equipment in fields like manufacturing, agriculture, and construction, which totaled 35% of energy demand. The last 28% was split between the miscellaneous power uses for residential homes and commercial buildings. This not only includes the typical businesses, but also power for hospitals, schools, and even warehouses.
AI and Energy Demand
The newest trends in society are also posing a major threat for power systems. While beneficial for the environment, powering electrical vehicles is expected to add between 100 and 185 extra Terawatt Hours across the country. Similarly, AI searches are adding a heavy toll to the current power grid demand. It is estimated that each AI server request takes between 23 and 30 times more energy than a regular internet search. In fact, if google searches were replaced with AI server requests, the amount of power consumed by these requests would equal the amount consumed by the entirety of Ireland. This neglects the energy costs to cool AI servers, which is expected to be around 50% of the costs for the AI searches themselves.
If this demand begins to creep and overtake supply, the results would be catastrophic. Banking and payment systems would be immediately impacted, which would make it very difficult as many people do not carry much cash anymore. Next, you wouldn’t be able to pump gas, which stops personal cars and public transportation from running. Supply chains would also stall, as product cannot be processed nor delivered to its destination. You wouldn’t even be able to communicate with your phone, as the cell towers would be down entirely. So how can we prevent the scales from tipping in favor of demand?
Updates are Needed
The most intuitive solution is by reinforcing the current power systems that we have. While exploring alternative energy is helpful, the simple truth is that our current power systems are incredibly inefficient. Around 70% of all transmission lines are over 25 years old and approaching their end of service. Similarly, around 55% of residential transformers are over 40 years old and also approaching their end of service date. In fact, it is estimated that transformer capacity would have to increase between 160% and 260% by 2050 to keep up with forecasted energy demand. Because of this outdated technology, around 5% of electricity transmitted was lost. By utilizing 2025 metrics, this would equate to around 202.45 Terawatt Hours, or enough electricity to full power over 14 million homes.
So, what is holding the US back from updating its power systems? Currently, the US electrical grid spans over 470,000 miles to compensate for the sheer electrical demand. To replace it entirely, it would cost just under $5 trillion dollars. Updating the infrastructure itself also takes time, and can take up to 2 years for generators and power transformers. Moreover, the price of updating infrastructure has increased drastically since the equipment was purchased several decades ago. In 2018 alone, transformers have almost doubled in price.
However, replacing the most outdated segments would yield great results. Newer transformers inherently have many more advantages compared to their counterparts from 40 years ago. Medium voltage dry type transformers, for example, are 99.4% efficient compared to older models and come with a 5-year warranty in the case of any problems. They are also much more resilient, as they have not been beat down by time or the elements.
Conclusion
With the improvements to the power grid, there would be far fewer power outages, more resilience to natural weather events, and much more stable energy costs. Most importantly, the power supply would be able to keep up with energy demand and be able to support more clean energy in the future. To help the US power grid keep up with the energy demand of tomorrow, it’s essential to start improving the infrastructure today.
