GREEN DATA CENTERS: SUSTAINABLE CLOUD INFRASTRUCTURE

Authors/Creators

Description

As global digital infrastructure expands rapidly, data centers now account for approximately 1–2% of the
world's total electricity consumption, a figure projected to rise significantly by 2030. Traditional data center
architectures, built on fossil fuel-powered grids and inefficient cooling systems, are no longer tenable from an
environmental or economic standpoint. This paper presents the Green Data Center Framework (GDCF), a
holistic model integrating renewable energy sources, advanced thermal management strategies, and AI-driven
resource optimization. The proposed framework achieves a Power Usage Effectiveness (PUE) of 1.2 against
an industry average of 1.8, a 75% renewable energy coverage rate, and a 50% reduction in server-level
energy consumption. Three operational pilot sites validate these results across diverse climatic conditions,
with an average Return on Investment (ROI) realized within 3 years. The paper further identifies
implementation barriers including capital costs, energy intermittency, and infrastructure scalability, while
proposing policy and technical pathways to democratize green data center adoption globally.
