By 2026, [global data center electricity usage is projected to double](https://www.datacenterdynamics.com/en/news/global-data-center-electricity-use-to-double-by-2026-report/), potentially reaching more than 1,000TWh (for context, 1 TWh could power 100 million homes for an hour). This surge in power consumption calls for innovative solutions to improve efficiency and sustainability. [Cogeneration](https://catalystpower.com/our-solutions/cogeneration/) is a standout solution, with a process that can significantly reduce the cost per kilowatt hour in data centers.  **What is Cogeneration?**  Cogeneration, also known as [combined heat and power (CHP)](https://blog.catalystpower.com/more-power-to-you/what-is-cogeneration), is an efficient approach to on-site power generation. It’s great for cost reduction, and in a data center context, it uses the waste heat produced by power generators to provide cooling through the cogeneration system.  **Benefits of Cogeneration for Data Centers**  - **Improved Energy Efficiency**: Cogeneration systems can achieve higher energy efficiency than traditional grid-powered data centers. How? Since cogeneration uses “[waste heat recovery](https://www.energy.gov/eere/iedo/waste-heat-recovery-basics),” every watt of electrical power that comes through the data center [must be thermally removed](https://www.electronics-cooling.com/2023/08/on-site-cogeneration-for-reducing-data-center-primary-energy-use-2/). That heat can be reused for cooling. The Department of Energy states that “recovering waste heat losses generates cost savings, reduces environmental impact, and improves workflow and productivity.”   - **Lower Power Usage Effectiveness (PUE)**: PUE is a crucial metric for data center efficiency. According to the [National Renewable Energy Laboratory](https://www.nrel.gov/computational-science/measuring-efficiency-pue.html), the most efficient data centers achieve PUE values of 1.2 or less. [Cogeneration can help lower PUE](https://chpalliance.org/wp-content/uploads/2021/06/CHPA-Data-Center-Factsheet.pdf) by increasing overall energy efficiency and reducing energy costs which directly impacts the PUE ratio.  **Cogeneration in the Context of AI and Crypto Mining**  As AI and cryptocurrency mining continue to drive up data center power consumption, cogeneration becomes increasingly relevant:  - **AI's Growing Energy Appetite**: AI tools like ChatGPT can [require up to 10 times the electricity](https://www.utilitydive.com/news/federal-government-prepares-second-attempt-to-survey-bitcoin-miners-energy-se/721063/) of traditional internet searches. By 2030, AI is expected to contribute significantly to a 160% increase in data center power demand, as stated by [Goldman Sachs Research](https://www.goldmansachs.com/insights/articles/AI-poised-to-drive-160-increase-in-power-demand).  - **Cryptocurrency Mining**: While there aren’t exact numbers, the U.S. Energy Information Administration estimates that [cryptocurrency mining accounts for anywhere between 0.6% and 2.3% of total U.S. electricity consumption](https://www.eia.gov/todayinenergy/detail.php?id=61364). Cogeneration could help offset this energy-intensive process since their data centers generate excessive heat and increase greenhouse gas emissions due to all the electricity usage.  - **Balancing Compute Power and Sustainability**: Compute power and cooling rank high on energy-intensive processes, and [graphics processing units](https://www.intel.com/content/www/us/en/products/docs/discrete-gpus/data-center-gpu/what-is-data-center-gpu.html) (GPUs) are used in technologies like AI, making them widely used in data center environments for their computing horsepower (think: gaming). As data centers upgrade to GPUs for AI workloads, cogeneration can help mitigate the environmental impact by improving overall energy efficiency.  **Implementing Cogeneration in Data Centers**  Integrating cogeneration systems can lead to substantial savings on energy bills, making data centers more resilient. To implement cogeneration effectively, data center operators should consider the following:  - **Energy Service Agreements:** When you partner with a cogeneration provider like Catalyst Power®, we will own and operate the system for you on your property. Learn how you can [add cogeneration without paying for equipment](https://blog.catalystpower.com/more-power-to-you/how-to-add-an-onsite-chp-unit-without-paying-for-equipment).  - **Sizing and Integration**: Properly size the cogeneration system to match the data center's electrical and thermal loads.  - **Monitoring and Optimization**: Continuously monitor system performance and optimize operations to maintain high efficiency.  **Moving Forward**  As data centers grapple with the energy demands of AI, cryptocurrency mining, and other compute-intensive applications, cogeneration offers a promising solution for improving efficiency and cost reduction. By harnessing waste heat for cooling, data centers can reduce their primary energy use and lower their PUE.  If you’re a data center owner interested in maximizing your efficiency with cogeneration, the potential benefits make it a technology worth exploring.
