How data centres affect electricity, prices, water consumption and jobs
Growing cloud and AI adoption is driving data centre expansion, yet evidence shows limited impact on power prices, improving water efficiency and significant economic benefits for local communities.
Data centres have become critical infrastructure for modern economies, supporting services ranging from digital communications and online commerce to emergency response systems and financial transactions.
As AI expands, demand for cloud computing continues to accelerate, increasing the need for additional data centre capacity worldwide.
Concerns about environmental impact often focus on electricity and water use, yet recent data indicate that data centres are not primary drivers of higher power prices and consume far less water than many traditional industries.
Studies show that rising electricity costs are largely linked to grid upgrades, climate-related damage and fuel prices instead of large-scale computing facilities, while water use by data centres remains a small fraction of overall consumption.
Technological improvements have further reduced resource intensity. Operators have significantly improved water efficiency per unit of computing power, adopting closed-loop liquid cooling and advanced energy management systems.
In many regions, water is required only intermittently, with consumption levels lower than those in sectors such as clothing manufacturing, agriculture and automotive services.
Beyond digital services, data centres deliver tangible economic benefits to local communities. Large-scale investments generate construction activity, long-term technical employment and stable tax revenues, while infrastructure upgrades and skills programmes support regional development.
As cloud computing and AI continue to shape everyday life, data centres are increasingly positioned as both economic and technological anchors.
