Artificial intelligence promises immense opportunities for innovation and efficiency. However, the rapidly escalating energy consumption of AI systems poses financial and reputational risks that business leaders cannot afford to ignore. Constructing an ethically conscious and energy-efficient AI strategy is imperative for companies seeking to maximise profits, accelerate growth, and lead responsibly.
Recent research by the University of Massachusetts shows that training a single AI model can emit over 626,000 pounds of carbon dioxide - nearly 5 times the lifetime emissions of a car. Amidst the AI energy concerns, the concept of “Green AI” aims to reduce carbon emissions by developing sustainable AI solutions such as optimising algorithms to consume less energy during training, employing more energy-efficient hardware and adopting renewable energy sources to power AI usage.
The exponential rise of AI overwhelms power grids unable to handle the energy appetite of AI systems. The powerful graphics processing units (GPUs) that drive AI training consume electricity on an entirely different scale than traditional central processing units (CPUs). A single AI training session can consume as much energy as 10 homes over the years. Grids were never designed to handle the enormous power densities that next-generation GPUs and power-hungry high-performing storage systems demand.
Experts warn of grid failures as surging data centre demand clashes with inadequate supply. Yet companies deploying AI act blind to these AI energy concerns. This shift toward sustainable energy solutions is not just about the environment, it’s about ensuring the data centres of tomorrow are equipped to handle the increasing demands of AI and high-performance computing workloads.
To effectively address the implementation of sustainable AI solutions, we must first understand the business implications of AI's energy consumption and their impact on operational costs and market positioning.
As the computational demands of AI are energy-intensive, they consume massive amounts of electricity and contribute substantially to greenhouse gas emissions. For example, training GPT-3, which has 175 billion parameters, used up 1287 MWh of electricity causing carbon emissions of about 502 metric tons, equal to driving 112 gasoline-powered cars for a year.
Also, since 2012, computing power for deep learning research has doubled every 3.4 months, surpassing Moore’s Law, which predicts a doubling in overall computer processing every two years. This remarkable growth represents an estimated increase of 300,000 times from 2012 to 2018, according to OpenAI researchers Dario Amodei and Danny Hernandez.
The financial implications of high energy consumption in AI are substantial. For instance, the operational costs for maintaining and training large AI models can be prohibitively high, not just in terms of direct electricity costs but also in the necessary cooling and infrastructure maintenance. These expenses can significantly impact the bottom line of businesses relying on large-scale AI operations. The market is increasingly valuing sustainability, with consumers and investors showing a preference for environmentally responsible companies. A report by McKinsey & Company highlights that sustainability is becoming a critical consideration for investors, with a growing emphasis on environmental, social, and corporate governance (ESG) factors. Businesses that ignore their carbon footprint risk not only higher operational costs but also potential reputational damage and reduced market appeal.
The discarded AI hardware contributes highly to electronic waste (e-waste). Improper disposal or inadequate recycling of this e-waste poses environmental risks. Electronic devices contain hazardous materials such as lead, mercury, and other toxic substances that, if not properly managed, can contaminate soil, water, and air, posing health risks to humans and ecosystems.
In 2019, the world generated 53.6 million metric tons (Mt), and only 17.4% of this was officially documented as properly collected and recycled. It has grown by 1.8 Mt since 2014, but the total e-waste generation increased by 9.2 Mt. This indicates that recycling activities are not keeping pace with the global growth of e-waste, according to the Global E-waste Monitor 2020 report.
Data centres consume substantial amounts of resources, primarily electricity, to process and store vast amounts of data. These data centres, equipped with powerful servers, storage units, and cooling systems, require vast amounts of electricity for their operations. The operational costs associated with these data centres are substantial. Beyond electricity, these costs include water usage for cooling systems and the extensive land areas required for facilities. The financial implications are significant for businesses, especially as energy prices fluctuate and environmental regulations become stricter.
In 2020, data centres consumed an estimated 196 to 400 terawatt-hours (TWh), equivalent to 1% to 2% of the world’s annual data centre energy consumption. In Denmark, data centre energy use is projected to rise six times by 2030 to account for almost 15% of the country's electricity use. At the same time, the US data centre demand is expected to grow by some 10% a year until 2030.
If the rapid growth of AI technology continues without adequate measures to mitigate its environmental impact, business may face the following consequences:
In response to these alarming AI energy concerns, the concept of "Green AI" comes up as a key solution. Green AI focuses on developing sustainable practices and technologies to reduce the energy consumption of artificial intelligence.
Traditional AI algorithms often require vast amounts of data and computational power to train, which means they need significant energy consumption. Green AI is tackling this head-on by developing efficient algorithms that learn with less data and fewer resources. These algorithms employ techniques like pruning, which removes redundant connections in neural networks, reducing the precision of calculations without sacrificing accuracy. That’s what we call “Working smarter, not harder”.
Neuromorphic computing mimics the brain's neural structure, enabling energy-efficient processing. These specialised chips are designed to perform complex AI tasks while consuming significantly less power than traditional processors. They excel in parallel processing, allowing for efficient execution of AI algorithms with reduced energy consumption.
The sheer computational power of AI generates immense heat, requiring powerful cooling systems to maintain optimal performance. Green AI is exploring innovative cooling solutions like liquid immersion, where servers are submerged in a special liquid that conducts heat more efficiently than air. AI-powered cooling systems are being developed that use machine learning to optimise cooling strategies, reducing energy consumption while ensuring optimal temperature control.
