“Will new Data Centers be seen as a problem going forward or will mankind understand how to make existing ones more efficient ?"
The Rise of Data Centers: A Necessity Amid Controversy
Data centers, the essential backbone of our digital world and the booming artificial intelligence (AI) industry, are proliferating rapidly. However, their exponential growth is raising significant concerns regarding their energy consumption, environmental impact, and the strain they place on local communities.
Why It Matters
In the United States, there are more than 5,000 data centers, which consume massive amounts of energy and occupy vast areas of land. In Europe, while fewer in number, data centers are also multiplying rapidly, particularly in France, Germany, the Netherlands, and the Nordic countries. These installations are critical for running the internet, AI, and cloud services, and are often backed by generous tax and energy incentives. However, their energy footprint is becoming a major source of contention.
The U.S. Case
The United States, as the global epicenter of data centers, continues to see rapid expansion of these facilities. According to CBRE (a leading real estate services company), investments in data centers exceeded $35 billion in 2022, with growth projected to continue at a double-digit rate. Northern Virginia remains the world's largest data center hub, hosting over 160 operational centers.
A key issue in the U.S. is energy demand. According to a 2023 Grid Strategies report, U.S. data centers will require nearly 40 additional gigawatts of electricity by 2028, nearly double previous estimates. This alarming figure reflects the growing pressure on the U.S. power grid, particularly in states like Texas, where electricity consumption is rising rapidly. In Northern Virginia, data centers now account for 20% of the state's electricity consumption, a percentage that continues to grow.
Controversial Projects
Virginia serves as a prime example. In 2022, a massive data center project in Prince William County sparked fierce opposition from residents. A 27-hour marathon meeting was required to approve the project, which is now being contested in court by locals who argue it will lower property values and create significant noise pollution. In Columbus, Ohio, Microsoft secured a full tax exemption on a $420 million data center investment, but the long-term economic impact for the community is minimal, with only 30 jobs created.
The European Case
In Europe, data centers are also expanding rapidly but face a different set of pressures due to stringent climate goals. The European Union has set ambitious targets for reducing carbon emissions through the Green Deal, which imposes stricter standards on data centers in terms of energy consumption and the use of renewable energy.
Key European Statistics
In 2022, Europe had around 4,500 data centers, concentrated in countries like Germany, France, the Netherlands, and the Nordic countries. Germany hosts around 10% of Europe's data centers, while the Netherlands accounts for 8%. The Nordic countries (Sweden, Norway, Finland) are increasingly prominent due to their ability to leverage renewable energy sources to power data centers.
In France, the electricity consumption of data centers in 2020 was around 10 TWh per year, representing about 2% of the country's total electricity use. This figure could triple by 2030, according to Ademe.
European Initiatives to Reduce Energy Impact
Countries like Sweden and Norway have taken a proactive approach by using green energy to attract data centers. For example, data centers in Norway run largely on hydropower, which supplies around 98% of the country’s electricity. This allows tech giants like Microsoft and Google to establish operations there while adhering to strict sustainability requirements.
In Sweden, Stockholm Data Parks has developed an innovative project where residual heat from data centers is used to heat residential buildings, creating a circular economy model that reduces overall energy consumption. Data centers in these parks feed energy back into the district heating network, allowing the city to reduce its carbon footprint while providing essential digital services.

Local Impact and Opposition
Like in the U.S., European data centers face growing opposition due to their impact on the power grid and local communities.
France: Growing Tensions
In France, regions like ?le-de-France and Bouches-du-Rh?ne, where many data centers are concentrated, are facing increasing pressure on land availability and power grids. For example, the Aix-Marseille metro area, which has become a significant digital hub thanks to its undersea cable connections, is attracting more data centers, but this presents challenges for urban planning and energy management.
The RE2020 law in France now mandates that data centers limit their carbon footprint. These facilities must use at least 30% renewable energy and meet stricter energy efficiency (PUE) requirements to comply with the country’s goal of carbon neutrality by 2050. However, these requirements raise costs and spark debates about balancing economic performance with sustainability.
Germany: Frankfurt Under Pressure
Frankfurt, Europe’s data center capital, is home to over 60 facilities and consumes more than 20% of the region’s electricity. The city is facing significant criticism, particularly regarding the impact of these centers on land prices and their heavy use of water for cooling. In 2023, residents launched several petitions to stop the construction of new centers in residential areas, calling for more sustainable solutions and better distribution of infrastructure across the country.
Tax Incentives and Controversies
In both the U.S. and Europe, data centers continue to receive substantial support through tax incentives. In the U.S., 30 states have passed legislation offering property tax abatements and other financial incentives to companies building data centers, often in the form of sales tax credits or equipment tax breaks.
In Europe, countries like Ireland are known for their highly favorable tax policies. Irish data centers, which account for about 25% of the country’s electricity consumption, benefit from attractive fiscal incentives despite growing concerns about national energy resources.
Conclusion?
If we want to avoid these ongoing data center crises, we need to think differently and consider whether it's time to make existing data centers more efficient by rethinking their renewal now.
They're filled with servers powered by processors that were efficient 20 or 25 years ago. Today, much more efficient servers exist, and Altwy not only enables the full utilization of these new resources while allowing for a smooth transition from the current infrastructure to the future of the Cloud, but also supports you and your company to reach your #ESG goals!
