The Impact of AI on Sustainability: A Double-Edged Sword
Share
Artificial Intelligence (AI) is one of the most transformative technologies of the century and is has emerged as a powerful tool in the fight for sustainability.
Offering innovative technological approaches, AI has helped address countless challenges in the sustainability domain.
However, like many technological advancements, AI's impact on sustainability is not without controversy. Let's explore how this cutting-edge technology is both helping and potentially hindering our efforts to create a sustainable future.
What Is AI in the First Place?
AI is an umbrella term that describes computer systems and algorithms that are capable of performing tasks that historically could only be performed by humans.
Those tasks include learning, reasoning, problem-solving, perception, language understanding, and even creative tasks.
There are various technologies below the AI umbrella, which include machine learning, deep neural networks, natural language processing (NLP).
The area of AI research is not new. In fact, AI research started in the 1950s, when the US Department of Defense trained computers to mimic human reasoning.
Since then, AI has seen many breakthroughs that pushed technological advancements – the latest being the revolutionary generative AI models around ChatGPT and others.
AI's Environmental Footprint
Energy Consumption
AI's potential to drive sustainability is massive, but it comes at an environmental cost. The massive data centers and powerful computers required to train and run AI models consume enormous amounts of electricity.
The evolution of AI is largely dependent on the evolution of computer processing power. Since 2012, the computing power needed to train the newest AI models has been doubling every 3.4 months and there is no end in sight.
In fact, training a single AI model can emit as much carbon as five cars over their lifetimes. This massive energy consumption significantly contributes to climate change.
Resource extraction
As with all electronic products, the computers used for AI processing use extensive raw materials.
That includes rare earth elements like palladium, which are often mined under environmentally and socially controversial conditions in developing countries.
To give you an idea of the extensive resource consumption through AI, just imagine that a single four pound computer needs around 1600 pounds of raw materials to be produced.
This resource consumption can lead to environmental habitat destruction and the exploitation of workers.
Electronic Waste
Due to the rapid technological progress, AI technologies lead to a lot of e-waste. Computer hardware often contains toxic metals lead or mercury and chemicals that can harm the environment if they are not properly disposed of.
The World Economic Forum estimates that e-waste will exceed 120 million metric tonnes by 2050
Water Consumption
In a similar vein, AI data centers uses large quantities of fresh water to cool down their equipment. It is estimated that AI cooling uses around 9 liters (2.3 gallons) of water per kWh of energy.
To set that into perspective, a single CHatGPT query can use 500ml (16 ounces) of water. Given there are around 10 million queries every day, that's 5 million liters (1.3 million gallons) every day for cooling.
If you keep in mind how scarce water already is in many regions, AI can exacerbate this critical issue.
Unfortunately, these environmental issues have a tendency to concentrate in poor regions of the world, where waste management, working conditions, and standard of living are already problematic.
Bias and Errors
Finally, there is a potential threat that AI models simply make mistakes.
The consequences can be insignificant, say if you get a wrong answer from a language model.
But the more decision power AI gets, the more dramatic consequences of errors or bias could become.
Disastrous examples already exist, for example the killing of civilians by AI weapons or self driving cars going rogue.
Similar consequences will likely arise in the use of AI for environmental use cases. Imagine for example the automated use of fertilizer or pesticides in agriculture, which could easily get out of hand.
Despite many concerns, AI's ability to optimize processes, analyze vast amounts of data, and provide innovative solutions to complex problems makes it a valuable asset in the pursuit of sustainability. The key lies in harnessing AI's power while minimizing its environmental footprint and potential for errors.
Let's explore some of positive ways AI is being used to promote sustainability across various sectors.
AI's Role in Driving Sustainability
Energy Efficiency and Renewable Energy
AI is playing a crucial role in optimizing energy consumption for existing infrastructure and accelerating the adoption of renewable energy sources.
Smart Home: There is a good chance that you're already using AI to save energy. Many off the shelf thermostats and other home appliances use AI to optimize their energy usage.
Estimates show that the average household saves around 10% energy by deploying smart home appliances.
Smart Grid Management: Similarly, AI algorithms can predict energy demand, optimize distribution, and integrate renewable sources more efficiently in the whole grid. For example, Google's DeepMind AI has reduced energy consumption in its data centers by 40% by optimizing cooling systems.
Renewable Energy Forecasting: AI models can analyze weather patterns and historical data to predict renewable energy output, allowing for better grid integration and reducing reliance on fossil fuels.
Sustainable Agriculture
The potential for AI applications in agriculture is incredible. AI is revolutionizing farming practices, helping to feed a growing population while reducing environmental impact.
Precision Agriculture: AI-powered systems can analyze soil conditions, weather patterns, and crop health to optimize irrigation, fertilizer use, and pest control. This precision approach can significantly reduce water usage and chemical runoff
Just check out this laser weeding robot straight out of a sci-fi movie that automatically kills weeds without using a single ounce of pesticides.
Crop Yield Prediction: Machine learning models can predict crop yields with increasing accuracy, helping farmers make informed decisions about planting and harvesting.
For instance, the AI startup Taranis uses high-resolution aerial imagery and AI to provide farmers with early detection of crop issues, potentially increasing yields by up to 7.5%.
Waste Management and Recycling
AI is improving smart waste management systems and boosting recycling efforts worldwide through creative application of image recognition and machine learning.
Smart Waste Sorting: One of the biggest challenges for effective recycling is sorting the waste properly. With only around 9% recycling rate for plastic across North America, AI has a lot of potential to improve the overall efficacy of recycling.
AI-powered robots can sort recyclables more efficiently than humans, increasing recycling rates and reducing contamination. For example, AMP Robotics has developed AI-driven robots that can sort recyclables twice as fast as human workers.
Predictive Maintenance:Predictive maintenance combines sensors in machinery with AI to predict when a machine is due for maintenance, before it breaks. That way, AI can predict when waste management equipment needs maintenance, reducing downtime and improving overall efficiency.
Conservation and Biodiversity
AI is becoming an invaluable tool in protecting ecosystems and endangered species.
Wildlife Monitoring: AI-powered cameras and drones can track and monitor wildlife populations more effectively than traditional methods. The organization RESOLVE uses AI-enabled cameras to detect poachers in real-time, helping to protect endangered species.
Habitat Analysis: Similar use cases have been developed to prevent deforestation and habitat loss in critical areas. Machine learning algorithms can analyze satellite imagery to track deforestation, monitor coral reef health, and identify areas in need of conservation efforts.
Sustainable Transportation
Wherever you have processes that need optimization, there's a good chance AI can help. Against that backdrop, AI is driving innovations in transportation that could significantly reduce carbon emissions and promote the adoption of EVs.
Traffic Optimization: AI can analyze traffic patterns and optimize signal timing to reduce congestion and emissions. For instance, Siemens' AI-powered traffic management system has reduced travel times by up to 25% in some cities, reducing emissions at the same time.
Electric Vehicle Optimization: AI algorithms can optimize EV charging schedules, predict battery life, and improve overall energy efficiency in electric vehicles. Optimizing charging schedules within the EV and optimizing charging itself can extend batter life yand sustainably transform the whole market.
Conclusion: Balancing Progress and Responsibility
As with every new technology, it is important that we do not view the impact of AI in a silo. Especially considering the high energy consumption of AI solutions, the sustainability of AI itself is closely connected to advances in the green energy transition. The more renewable and sustainable energy we produce, the more sustainable will AI solutions get.
Nonetheless, as we harness the power of AI to drive sustainability, it's crucial to address the technology's own environmental impact. Efforts are underway to develop more energy-efficient AI systems and optimize AI data centers.
