Green Cloud Computing Guide: Cutting Data Center Energy Use and Carbon Emissions

Green cloud computing aims to reduce the massive electricity consumption of data centers, which the IEA estimates used 415 terawatt-hours in 2024, about 1.5 percent of global power. The article explains how virtualization, energy-efficient processors, renewable energy sourcing, and smart cooling systems lower carbon emissions without sacrificing performance. The rapid growth of AI is driving data center electricity use toward 945 TWh by 2030, according to IEA projections. Major cloud providers like Microsoft, Amazon, and Google have reported 119 million metric tonnes of CO2 emissions, an 18 percent increase from previous reporting. The article highlights carbon-aware computing as a key future strategy, allowing flexible workloads to run when cleaner electricity is available.
