Alister Hamilton, an expert on global oil depletion, warns about running out of oil by the 2030s due to increasing energy input for extraction. He discusses the Energy Return On Investment (EROI) and how accessing lower-grade oil will lead to oil reserves being inaccessible worldwide. The urgency of transitioning to renewable energy is emphasized to prevent a global crash.
Oil reserves globally will be inaccessible by the 2030s due to declining Energy Return On Investment (EROI).
Decentralizing energy systems is crucial to counter the impending energy crisis and promote sustainability.

The Thermodynamic Model of Oil Production
Alistair Hamilton, a researcher at the School of Engineering at the University of Edinburgh, discusses a thermodynamic model he and his team created to understand energy input and output. By analyzing data from regions like the North Sea, Norway, and Alaska, they found that extracting fossil fuels consumes more energy than what is gained. Deeper extraction requires more energy, and inefficiencies in fuel usage amplify the problem.
Energy Return on Investment Across the Globe
Examining regions like the UK, Norway, and the USA, Alistair's team predicted that by 2031, extracting oil and gas will not be energy positive. This analysis indicates that energy subsidies are required to sustain current production levels. The study highlights the need for policymakers to consider the declining net energy returns in the oil and gas industry.
Transition to Decentralized Energy Systems
Alistair advocates for decentralizing energy systems to counter the impending energy crisis. By leveraging technologies like Stirling engines and heat converters, it is possible to shift towards more efficient and sustainable energy production. Decentralization offers a solution to the escalating energy costs and promotes local energy independence.
Policy Implications and Urgency for Transition
Despite niche recognition, Alistair emphasizes the urgent need for policymakers to address the impending energy crisis. Collaborative efforts with experts like Louis R., who advocates for energy system redesign based on natural principles, can pave the way for a more resilient energy infrastructure. Transitioning to decentralized, efficient energy systems is crucial for mitigating the consequences of declining fossil fuel reserves.
2050? 2100? Never? That’s understandable given the IPCC models access to oil until 2100; politicians like Rishi are betting big on North Sea deposits. Petroleum is the life blood of our global economy, and it’s difficult to imagine it drying up. More often, when we talk about transitioning away from fossil fuels, it’s because of the necessity to limit global warming—not because we run out.
But a team in Scotland are warning exactly that—we’re running out. Fast. Alister Hamilton is a researcher at the University of Edinburgh and the founder of Zero Emission Scotland. He and his colleagues self-funded research into oil depletion around the world and the results are shocking: We will lose access to oil around the world in the 2030s.
They calculated this by establishing the Energy Return On Investment (EROI) and found that whilst there will still be oil deposits around the world, we would use more energy accessing the oil supply than we would ever get from burning it. This is because we’re having to mine further into the earth’s crust to access lower-grade oil. According to their calculations, the oil in the North Sea will be inaccessible—in a dead state—by 2031, and the oil in Norway by 2032. Around the world, oil reserves see the same trend through the 2030s.
Petroleum is the life blood, and we haven’t yet built out a different circulatory system to support renewable energy—in less than a decade, the world as know it could crash.
