Cloud Sustainability: Green Initiatives and Energy Efficiency.

“Sustainability is no longer a niche topic. It’s a business imperative. As technology leaders, we have a responsibility to help our clients and the world address climate change and other pressing environmental issue” 

Arvind Krishna (Chairman and CEO, IBM)

Nonprofit research firm Electric Power Research Institute conducted a very interesting study related to Cloud sustainability and energy consumption by AI tools, and the results are shocking.

Did you know that every ChatGPT query consumes 2.9 watt-hours of energy? This is 10 times more than a single search query executed on Google.

To put this into perspective, a typical household in the US consumes 29 kilowatt-hours (kWh) daily. With around 200 million queries, ChatGPT alone has a total daily energy consumption of approximately 10,000 US households.

And we are only talking about one AI tool here!

As per UNEP (United Nations Environment Program), the tech industry is responsible for almost 2% of global carbon emissions, which is exactly the same as that of the aviation industry.

And, we have barely scratched the surface here.

Data Centers alone consume around 3% of global electricity production, which is about to double by 2030, as more and more tools, applications, and cloud-based solutions emerge. 

Microsoft has already announced that their overall CO2 emissions have increased 30% since 2020, mainly due to data center expansion, and Google’s global greenhouse gas emissions in 2023 were double compared to 2019.

No doubt, digital transformation has changed how we work, operate, share information, and solve our life problems.

But it has come with an expensive price tag of sabotaging our environment and our world. 

And this is very tough to ignore.

With the increasing usage of data centers and electricity, which directly surges greenhouse emissions and other harmful elements, the topic of Cloud computing sustainability isn’t just a trendy buzzword but an immediate and urgent need of the hour. 

In this blog, we will explore how the technology that is causing this problem is being used to create solutions as well.

And the outcomes are really interesting. 

The Digital Dilemma: When Innovation Means Harming The Environment

Picture this: every time you stream a movie, send an email, or ask an AI assistant a question, you’re tapping into a vast network of data centers that collectively consume as much energy as entire nations. 

Global data centers now consume energy equivalent to Spain’s total annual consumption, a staggering, unmissable reality that puts the environmental impact of our digital lives into stark perspective.

When you engage with ChatGPT or other AI models, each conversation can consume several watt-hours of energy, as shared in the beginning. 

Industry analysts estimate that supporting Gen AI workloads and related Cloud tech usage could require tens of megawatts per year per major provider, with operations potentially consuming energy equivalent to tens of thousands of homes.

This isn’t just about big tech companies; It’s about every business that relies on cloud services. 

From the small startup storing customer data to the multinational corporation processing billions of transactions, the collective digital footprint of cloud computing has created an environmental challenge that demands cloud computing and sustainability initiatives.

Right now.

How Technology Can Become the Solution to Its Own Problem?

What’s remarkable about the current crisis of sustainability in Cloud Computing is how the industry has responded not with denial or delay, but with innovation and determination. 

The same technological prowess that created the problem is now being harnessed to solve it, creating what many experts call the revolution of Cloud and Green Computing.
