Cloud Computing Sustainability: How Green Is the Cloud?
Is the cloud the answer to environmentally sustainable IT? The answer is mostly "yes". Read this article to learn five facts on why cloud computing is more eco-friendly than conventional data centers — and why the difference will become even more pronounced in the future.
How does cloud computing compare to traditional data centers in terms of energy use?
Data centers account for approximately 1-2% of total global energy use. Despite the increase in the number of data centers and workloads, this percentage has remained stable since at least 2010, indicating that data centers have become more efficient over time. Moving workloads to larger, centralized cloud data centers can help reduce overall energy consumption.
What role do carbon emissions play in cloud service selection?
By 2025, carbon emissions will likely be one of the top three criteria businesses consider when selecting a cloud provider. This trend reflects a growing emphasis on reducing carbon footprints, particularly since the COVID-19 pandemic, suggesting that cloud computing is becoming increasingly sustainable.
Are major cloud providers committed to renewable energy?
Both Amazon and Microsoft have pledged to power their operations with 100% renewable energy by 2025. Google Cloud aims for 24/7 carbon-free energy by 2030. While the specifics of how they will achieve this are not fully detailed, their intentions to invest in renewable energy infrastructure are seen as positive steps toward sustainability in cloud computing.
