Is Artificial Intelligence Bad for the Environment? 

Artificial intelligence has become a powerful force in our world, but we are starting to see its environmental drawbacks. AI systems consume massive energy and resources, raising concerns about their carbon footprint.

A study by MIT shows that training a single large AI model can emit as much carbon dioxide as five cars over their lifetimes. The environmental impact of AI is a growing issue that needs to be addressed.

As AI becomes more popular, we must consider how it affects our planet. By examining these issues, we can work towards more sustainable AI practices that balance innovation with environmental preservation.

AI uses a lot of energy. Training large AI models can produce as much carbon dioxide as five cars do in their lifetime. By 2027, AI could use up to 134 terawatt-hours of electricity annually- about 0.5% of global energy use.

To truly grasp the environmental impact of GPT-4, OpenAI's cutting-edge large language model released in 2023, we must consider its carbon footprint in context. Estimates suggest that the training process for GPT-4 may have resulted in emissions between 12,456 and 14,994 metric tons of CO2 equivalent. 

This is significantly higher than its predecessor, GPT-3, which was estimated to emit about 552 tons of CO2 equivalent during training.

The same study also indicates that training GPT-4 consumed between 51,772,500 and 62,318,750 kWh of electricity. This is equivalent to the annual electricity consumption of thousands of households across regions.

Consequently, the wide range in estimates is due to uncertainties about the exact training process and the carbon intensity of the electricity used.

Moreover, AI needs water, too. Data centres use water to cool their servers. Some estimates say AI could use up to 6.6 billion cubic meters of water by 2027. An average ChatGPT session with 10-50 responses can use up to half a litre of fresh water.

AI's environmental footprint extends from development to deployment and maintenance. E-waste from rapidly outdated AI hardware adds to environmental issues. The ICT industry, including AI, could account for 14% of global emissions by 2040.

While training emissions are substantial, the per-query emissions for using GPT-4 are much smaller:

Therefore, we can estimate that each AI Overview query will emit approximately 0.8-1g of CO2, much higher than the current emission. This represents a 300-400% increase in emissions per query.

In addition, we see a shift in user search behaviour to conduct fewer searches to find the information they're looking for, as AI Overviews could provide more comprehensive results in a single query. Users might also spend more time analysing the AI-generated overview on the search results page instead of quickly clicking through to other websites.

It's, therefore, crucial to consider this impact in the broader context of technological advancement and its potential benefits. Google claims AI could help predict floods and make traffic more efficient.

With the rapid growth of AI, a hidden cost is also beyond financial implications, extending to substantial global impacts. However, in terms of economic cost, the financial costs are equally eye-opening. Running ChatGPT costs an estimated £80,000 daily, potentially rising to £32 million monthly with increased usage. 

These figures underscore the substantial resources required to maintain and operate advanced AI systems.

These costs extend beyond training. Ongoing operations and frequent model updates add to AI's environmental toll. For instance, generating 1,000 images with Stable Diffusion XL emits as much CO2 as driving an average car for 6.6 km.

Moreover, we have seen that training large AI models can emit over 284,000 kg (626,000 pounds) of CO2. This staggering amount highlights AI's significant carbon footprint.

This requires immense computational power, such as graphics processing units (GPUs) and tensor processing units (TPUs), which are essential for handling the high level of parallel processing. 

The scale of these models is staggering. For instance, GPT-1 was considered 'large-scale' with 117 million parameters and 600 billion tokens. In contrast, GPT-4, released in 2023, boasts roughly 1.7 trillion parameters and 13 trillion tokens. 

This figure doubled when considering the emissions from manufacturing computer equipment, broader computing infrastructure, and running the model post-training. A study from Hugging Face estimated that training their large language model, BLOOM, led to 25 metric tons of carbon dioxide emissions.

We must be mindful of these environmental costs as we continue developing and deploying AI technologies.

The computational power needed to sustain AI's growth doubles roughly every 100 days. This rapid expansion is causing AI's energy use to accelerate annually between 26% and 36%. 

Big tech companies like Microsoft and Google have seen their carbon emissions rise due to the expansion of AI-related data centres.

Training large AI models is especially energy-intensive. For example:

To put this in perspective, 1,300 MWh could power 130 UK homes annually. Moreover, experts estimate that by 2028, AI could use more power than some countries.

The scale of this consumption is staggering. Goldman Sachs Research estimates that data centre power demand will grow 160% by 2030. Data centres worldwide consume 1-2% of overall power, but this could rise to 3-4% by decade's end. 

When we looked at a single ChatGPT query that requires 2.9 watt-hours of electricity, it was nearly ten times more than a Google search, which requires 0.3 watt-hours. The International Energy Agency predicts a dramatic increase in data centre power usage. By 2026, these centres are expected to consume 1,000 terawatts of electricity, doubling their 2022 consumption and matching Japan's current total energy use.

This surge in demand should push tech companies to invest in renewable energy, such as solar power, heat pumps and wind power, to explore emerging generation capabilities. 

AI's water footprint is substantial and concerning. Even a simple conversation with ChatGPT, consisting of 10 to 50 questions, can use up to 500 millilitres of fresh water. 

Experts foresee that global AI demand may require 4.2 – 6.6 billion cubic meters of water withdrawal by 2027, more than Denmark's total annual water withdrawal. This strain on water resources could lead to social turbulence and worsen existing water waste and scarcity issues.

AI’s thirst stems from data centres, which require massive amounts of water for cooling. Google, Microsoft, and Meta's data centres worldwide extracted an estimated 2.2 billion cubic metres of water in 2022. As AI workloads grow, so does water usage. Google's data centre water consumption jumped 20% from 2021 to 2022, while Microsoft's increased 34%.

This growing water demand has sparked concerns in communities hosting AI facilities. Residents of West Des Moines, Iowa, home to a data centre running GPT-4, filed a lawsuit after learning the facility used 6% of the district's water in July 2022. 

To address this, big tech companies have replenished watersheds to offset their cooling water consumption. However, more transparency and innovation are needed to build sustainable AI practices and mitigate emerging environmental inequity. 

We are facing a growing e-waste crisis as AI technology advances. Global e-waste production reached 65 million metric tons as of 2022. This surge is partly due to AI's demand for constant hardware upgrades.

Experts predict this figure could double by 2030 if current trends continue.

Companies are rapidly upgrading to support AI, creating graveyards of outdated tech. The AI revenue is projected to reach £37.3 billion by 2027, potentially escalating the e-waste problem. 

Current e-waste recycling methods need to be improved. Only 22% of e-waste is recycled responsibly. Manual disassembly is inefficient and hazardous for workers. 

However, the lack of transparency from for-profit AI companies hinders accurate assessment of AI's carbon footprint. 

Although governments are starting to act, the EU's Right to Repair law, effective in 2024, aims to make electronic devices last longer. Similar legislation is being considered in other countries. To address this crisis, we need collaborative efforts towards sustainable AI hardware recycling practices.

Artificial Intelligence (AI) presents both opportunities and challenges for our planet. On the positive side, it can enhance energy efficiency in buildings and industries by predicting usage patterns and minimising waste. A recent study found AI models can improve business energy efficiency by 10-40%. 

For example, Google's DeepMind has optimised cooling systems in data centres, reducing energy consumption and carbon emissions. In renewable energy, GE Renewable Energy uses AI in wind turbines to improve performance and maintenance.

In transportation, ride-hailing apps using AI to optimise routes have resulted in 69% more climate pollution by displacing more sustainable public transit. The convenience and lower costs might spur increased demand for goods or services, leading to a "rebound effect."

To harness AI's environmental potential while minimising negative impacts, some factors need to be considered, such as:

AI's role in environmental sustainability remains complex. By addressing challenges and maximising benefits, we can work towards a future where AI becomes a powerful tool for planetary health.

We're witnessing an unprecedented surge in AI's growth and impact. The AI market is projected to reach £628.06 billion by 2030, with an annual growth rate of 28.5% from 2024 to 2030. This rapid expansion comes with significant environmental implications.

However, here are key statistics, facts, and figures that highlight AI's growing influence:

These statistics reveal AI's transformative impact across industries while underscoring the imperative for responsible development and implementation. As AI integration accelerates, balancing innovation with ethical considerations becomes crucial for maximising its benefits and minimising potential risks.

We're seeing a global race in AI adoption, with several nations leading the charge. The Global AI Index, which analyses 62 countries based on investment, innovation, and implementation, provides insights into this trend. 

Here's an overview of the top AI-using countries in 2024: 

These countries lead in AI adoption, research, and innovation. However, the AI landscape evolves rapidly, and rankings may shift as more nations prioritise AI development. 

Please note that due to the rapidly changing nature of the AI field and differences in reporting methodologies, these figures should be considered approximate and may vary depending on the source and time frame used.

Sustainable AI practices are crucial for balancing technological advancement with environmental responsibility.  Consequently, it could be part of the solution. This means using more energy-efficient hardware and renewable energy sources to power AI systems. 

These algorithms could reduce the energy needed to train and run AI models. For example, AI systems in smart grids help minimise energy waste by adjusting power distribution in real time. This has saved millions of pounds and cut carbon emissions.

These efforts, if successful, will significantly reduce the footprint of AI technologies. Hardware innovations like quantum computing and advanced chip designs are also being developed to minimise AI’s energy demands.

Organisations adopting AI can make their systems more sustainable by:

Sustainable AI isn't just environmentally responsible—it's economically smart. Industries can balance innovation with environmental responsibility by prioritising sustainability in AI development.

Ironically, AI itself plays a crucial role in managing its waste. Advanced sorting systems using machine learning algorithms can identify and categorise AI components with 95% accuracy.

This precision enables more efficient recycling of valuable materials. It would allow the system to extract precious metals and rare earth elements containing valuable materials. 

Recycling these components reduces the need for new mining and prevents hazardous waste from contaminating soil and water. These solutions not only cut costs but also significantly reduce carbon emissions. 

We have seen so far that the environmental imapct of AI is enormous, but how can it compare to everyday activities?  

On average, a car emits about 4.6 metric tons of CO2 annually. A recent AI language model, similar to those commonly used today, produced between 12,456 and 14,994 metric tons of carbon dioxide emissions during its training process.

For comparison:

These small things add up, but an AI model's impact is much higher, especially during training stages.

AI's water usage is another concern. Training large language models can use up to 700,000 litres of water, equivalent to manufacturing 320 electric vehicles. 

In comparison:

AI development requires vast amounts of electricity. Running a typical AI model (GPT-3) can use the same electricity for approximately 130 homes in the US annually (depending on the AI model). For comparison:

While AI brings breakthroughs, the energy use behind it needs awareness.

However, AI isn't all bad news for the environment. It helps optimise energy grids, reduce waste, and improve sustainable practices. For example, AI-powered precision agriculture reduces fertiliser use, benefiting farmers and ecosystems. 

While AI's environmental footprint is significant, especially as it becomes more integrated into daily life, its potential to address complex environmental challenges remains substantial. However, to ensure AI's development aligns with sustainability goals, we must critically evaluate its energy consumption and carbon emissions relative to traditional activities.

By doing so, we can identify areas for optimisation and promote the development of more environmentally friendly AI technologies.

As artificial intelligence (AI) becomes more prevalent, many seek alternatives without complex algorithms or massive data centres. Here are some key options.

Companies can reduce their carbon footprint by choosing alternatives while achieving automation and efficiency goals. 

We are at a crossroads with AI's future. Its potential benefits are immense, but so are its environmental risks. We need to strike a balance between innovation and sustainability.

Recent data shows AI adoption is accelerating rapidly. A 2023 McKinsey survey found that 55% of companies now use AI in at least one business function, up from 50% in 2022. In addition, a PwC study suggests AI could add £12.8 trillion to the global economy by 2030. That's a staggering figure, more than the current combined output of China and India.

As AI becomes more advanced, critical areas need careful consideration. It is essential to balance the risks and benefits of AI.

According to GreenMatch environmental expert Inemesit Ukpanah, 

As we move forward, we need a nuanced approach to AI development. We should harness its power to solve global challenges while minimising its environmental footprint.

Policymakers, tech companies, and researchers must work together to create responsible AI practices. This includes setting energy efficiency standards for AI systems and investing in green computing technologies.

By taking a balanced approach, we can reap AI's benefits while safeguarding our planet's future.
