Reduce IT energy consumption
Organizations can greatly increase their energy efficiency and reduce their carbon footprint through public cloud computing, on-prem energy-efficient technologies and using renewable power, such as geothermal, solar power and water cooling.
Computing power requires massive amounts of energy. Computers, data centers and networks consume about 10 percent of the world’s electricity, demanding about 190 terawatt-hours (190 trillion watts) of energy per year, which is more electricity than the entire state of New York1 uses over the same period.
The number of terawatt hours consumed by computing has stayed relatively consistent since about 2015, despite the increase in the number of data storage centers. That is because public cloud resources consume less energy than private clouds, and private clouds consume less energy than traditional data centers. Some cloud providers, such as Microsoft Azure Cloud, can track direct and indirect greenhouse gas emissions and data efficiency when moving from on-premises storage to cloud storage.
Reducing energy demand also saves energy costs, which contributes to the CFO’s agenda and helps the CIO build a coalition around ESG. To promote green IT practices, organizations can retool data centers to consume power in the following eco-friendly ways:
- Improve energy storage efficiency by using flash technology
- Use ARM processors, which have fewer transistors and require no cooling, for significant power budget savings
- Switch from copper ethernet networks to fiber cables
- Leverage artificial intelligence and machine learning to adjust a data center’s cooling requirement
- Engage IoT sensors to maximize the use of data center space, improve facility airflow and reduce cooling power
Review supplier governance
To achieve Scope 2 emissions reductions, CIOs and IT departments must also address waste and emissions by their vendors, which includes their electricity consumption.
