Green Computing Infrastructure: A Crucial Need for India’s Technological Future

As India strides forward in the realms of semiconductors, artificial intelligence (AI), and quantum computing (QC), the sustainability of this technological progression is of paramount importance. The triad of semiconductors, AI, and QC promises to shape India’s tech destiny, but this progress must be underpinned by a robust and eco-friendly computing infrastructure. This article delves into the necessity for a green computing infrastructure (GCI) in India, emphasizing energy efficiency and sustainable water use.

The Environmental Impact of Computing

Carbon Emissions from Cloud Computing

Cloud computing, while revolutionizing data storage and processing, is responsible for 2.5-3.7% of global greenhouse gas emissions. Given India’s advancements in renewable energy, there is a significant opportunity for the high-tech sector to be driven by green energy. However, the environmental impact extends beyond carbon emissions to substantial water consumption.

Water Consumption in Semiconductor Manufacturing and Data Centers
Semiconductor fabrication units typically consume two million gallons of water daily, while data centers (DCs), essential for QC and AI, require 5-20 million liters of water per day primarily for cooling operations. India’s limited water resources necessitate innovative solutions to manage and reduce this consumption effectively.

India’s Water Resources and Challenges
In 2020, India’s average annual water availability was 1,123 billion cubic meters, a mere 13% of Brazil’s renewable water resources. High water consumption levels in tech hubs like Bengaluru and the National Capital Region highlight the urgent need for sustainable water management practices.

The Rise of Data Centers in India
Government Support and Growth Projections
India’s data center sector is burgeoning, spurred by the Union Budget 2022 which granted “infrastructure” status to data centers. This has attracted substantial long-term investments, with states like Tamil Nadu, Uttar Pradesh, Telangana, and Maharashtra providing assured power and round-the-clock water supplies. The sector is projected to grow at an 18% compound annual growth rate over the next six years, leading to increased demand for both power and water.

Innovations in Water Management
US-based hyperscale data centers by Google, Meta, and Microsoft are pioneering the use of recycled water and air cooling systems to minimize freshwater use. By 2030, these companies aim to be water-positive, contributing to the restoration of local wetlands and enhancing water sustainability. India can learn from these innovations to develop its own sustainable data centers.

Building a Green Computing Infrastructure in India
Sustainable Practices for Data Centers
To ensure sustainable growth, India’s green computing infrastructure must incorporate advanced water use technologies tailored to local conditions. This includes closed-loop and direct chip cooling systems adapted for high ambient temperatures. Additionally, data centers should contribute to the rehabilitation of degraded wetlands and lakes, enhancing local water resources.

Role of Artificial Intelligence
AI can play a critical role in optimizing data center operations, including cooling, energy use, and maintenance tasks. By leveraging AI for real-time monitoring and management, data centers can achieve greater efficiency and sustainability.

Global Climate Imperatives
The Freshwater Challenge
The Freshwater Challenge, launched at the COP28 in Dubai, underscores the global commitment to restoring degraded rivers and wetlands by 2030. As part of the international community, India must align its GCI initiatives with these global efforts to enhance freshwater sustainability.

India’s technological advancement in semiconductors, AI, and QC must be accompanied by a commitment to environmental sustainability. Developing a green computing infrastructure that prioritizes energy efficiency and water conservation is essential for sustainable growth. By adopting innovative technologies and practices, India can transform its high-tech cities into water-positive ecosystems, setting a global example for sustainable tech development.
