Energy efficiency is key to sustainability. It is also key to lowering operating costs. For both reasons, it has become a top priority for data center operators and their clients. With that in mind, here is a straightforward guide to energy efficiency and sustainability in Denver data centers.

Energy efficiency in data centers

There are five main factors that determine energy efficiency in data centers. Here is an overview of them.

Building design

Modern data centers are designed to promote energy efficiency. They are also built using as much energy-efficient material as possible. Where possible, they incorporate facilities to create renewable energy (e.g. solar panels). Although this does not make the data center more energy efficient in itself, it does reduce both the use of mains electricity and the production of carbon.

Power usage effectiveness (PUE)

PUE is a key metric that measures total facility energy divided by IT equipment energy. A lower PUE (close to 1.0) indicates more efficient energy use, meaning less power is wasted on cooling, lighting, and other non-IT functions.

Cooling systems

Cooling is one of the largest energy consumers in data centers. Efficient techniques like liquid cooling, hot/cold aisle containment, and free-air cooling (using outside air in cooler climates) reduce the need for traditional air conditioning, significantly lowering energy use.

Energy-efficient UPS systems

Traditional UPS systems waste power through conversion inefficiencies. Modern UPS solutions with high-efficiency ratings reduce losses and improve backup power management.

Advanced power management

Smart power distribution units (PDUs), dynamic voltage scaling, and automated power controls adjust energy use based on real-time demand, preventing unnecessary consumption.

Benefits of green data centers for businesses

These are just five of the most important benefits of green data centers for businesses.

Lower operating costs

Green data centers incorporate innovative energy-efficient designs, smart cooling systems, and AI-powered monitoring to optimize energy use. These result in lower operating costs. Furthermore, many green data centers can produce their own renewable energy (e.g. through solar panels), further reducing costs.

Operational resilience and risk reduction

The less energy a data center uses, the less vulnerable it is to issues with the energy supply. These include pricing fluctuations as well as supply disruptions.

Regulatory adherence

Stakeholders such as regulators and governments are becoming more active in enforcing sustainability standards on businesses. In many areas, they are focusing particularly on resource-intensive business sectors such as data center operations. Green data centers help to keep businesses ahead of these regulations.

Competitive edge

Similarly, many potential data center clients are now pursuing their own sustainability goals. Achieving these goals often requires them to work with vendors with similar aims. Even if this is not explicitly stated during the procurement process, it is increasingly likely to be a consideration.

Future-proofing

Making a data center as energy efficient as possible can make it a lot easier for it to adapt to developments in technology. For example, quantum computing requires massive amounts of cooling to maintain a correct operating temperature. Unless a data center is highly energy efficient, it is unlikely to cope with this.

How Denver data centers contribute to sustainability

Here is an overview of the five main ways that Denver data centers contribute to sustainability.

Renewable energy integration

Many Denver data centers utilize renewable energy sources such as wind and solar power to decrease dependence on fossil fuels. Colorado’s investment in clean energy makes it easier for data centers to integrate green power into their operations.

Local utility providers offer incentives, such as discounted rates and tax credits, to encourage businesses to transition to sustainable energy sources. By making use of renewable energy, these facilities not only reduce their carbon footprint but also lower long-term electricity costs.

Energy-efficient infrastructure

Upgrading to energy-efficient hardware plays a critical role in reducing power consumption. Many Denver data centers implement high-performance, low-power servers and storage solutions designed to optimize computing efficiency.

Advanced power distribution units (PDUs) help manage electricity use effectively, while server virtualization reduces the number of physical machines required. Additionally, modern lighting systems, such as LEDs, further contribute to overall energy savings.

Climate-based cooling solutions

Denver’s high altitude and cool climate offer a natural advantage for data center cooling. Many facilities use free-air cooling, which draws in outside air to help regulate server temperatures. Since Denver experiences cold temperatures for much of the year, this method significantly reduces reliance on traditional, energy-intensive air conditioning.

Advanced cooling technologies

In addition to climate-based cooling, data centers adopt energy-saving technologies like liquid cooling, which transfers heat more efficiently than air-based systems. Hot/cold aisle containment improves airflow, while AI-powered cooling systems adjust dynamically to optimize efficiency and reduce energy waste.

Participation in energy efficiency programs

Data centers in Denver often work with local energy providers to adopt best practices in efficiency. These programs offer financial incentives for upgrading equipment, implementing efficient cooling methods, and optimizing power usage, helping businesses reduce both costs and environmental impact.
