As digital demand grows, so does the need for data centers. Behind this convenience, however, lies a major cost: energy. Data centers use massive quantities of electricity to operate servers and cooling systems, which can drive up local energy costs and strain infrastructure. Understanding how they affect your energy bills is crucial for businesses to make informed choices.
Data centers are specialized facilities that contain computer servers, networking equipment, and data storage systems. They support everything from streaming services to financial transactions by processing, storing, and transmitting massive volumes of digital data.
These operations require constant uptime, which means continuous power for servers and large-scale cooling systems to prevent overheating. High-performance hardware, redundancy systems, and climate control all contribute to their significant power demands.
With cloud computing, artificial intelligence, and data-driven industries expanding rapidly, data center operators expect their power usage to continue growing as current facilities increase capacity and new data centers emerge to meet the growing demand.
As a result, data centers are now a focal point in conversations about environmental impact and responsible electricity consumption.
Data centers often require tens or even hundreds of megawatts to operate, placing enormous electricity demands on local power grids. This demand can lead to electrical grid congestion, especially in areas already facing energy supply challenges. Additionally, data centers may use significant amounts of water for cooling, which can strain local water resources, particularly in drought-prone regions. The result is increased stress on public infrastructure, sometimes requiring costly upgrades or expansions to maintain reliability and avoid blackouts.
Greater energy demand from data centers can push up electricity prices for nearby residents and businesses because electricity supply is not growing at the same pace.. Utilities will also need to invest in grid upgrades or additional energy generation to meet new power requirements, often passing those costs along to consumers.
In some cases, the presence of a new data center can affect local power prices from energy suppliers and utilities, affecting peak-hour rates or baseline costs. This ripple effect makes energy costs more volatile and harder to predict.
A large-scale U.S. data center can use about 176 TWh (terawatt-hours) a year, with the U.S. Department of Energy (DOE) predicting that this number will climb to 325 TWh or even 580 TWh by the end of 2028.
Hyperscale/large data centers can consume 100 TWh or more annually, according to the DOE.
Data centers generate significant heat due to continuous server activity. Without adequate cooling, temperatures can exceed safe levels within minutes, risking equipment damage and data loss.
Global data center power consumption is roughly 1–2% of total global electricity use, or about 200–300 TWh annually, according to International Energy Agency (IEA). As digital services expand, this figure is expected to grow, driving concerns over sustainability.
Improvements that can boost the power usage effectiveness of new data facilities include:
- Energy-efficient hardware
- Liquid cooling systems
- Optimized facility airflow
- Renewable energy sources
- Advanced software to better distribute workloads
AI-powered efficiency tools, and low-power server technologies. Regulations and investor pressure are also driving the push for more sustainable operations.
Key strategies to reduce the amount of power these centers use include:
- Using more efficient cooling systems
- Consolidating workloads
- Use of AI to optimize server operations
- Retrofitting aging infrastructure
- Implementing real-time monitoring to manage energy usage dynamically
Main contributors to data center energy use include:
- 24/7 server uptime
- Constant cooling demands
- Inefficient legacy systems
- Power-hungry IT hardware
- Redundancy systems that double equipment load for reliability
Data centers use about 1–2% of the world’s electricity. While this number may seem modest, many experts expect it to rise significantly due to the impact of AI, cloud computing, and other changes across a wide range of industries.
