Introduction – Why OpenAI Needs So Much Power
Artificial intelligence isn’t only about algorithms, neural networks or programmatic solutions that help you order an Uber from your 25th-floor apartment — it’s also about power. All AI models, whether it’s a simple recommendation engine or a more sophisticated tool such as GPT itself, need tremendous computational power. And power also brings one inescapable fact: demand for energy.
By early 2025, OpenAI was consuming an estimated 0.23 gigawatts (GW) of power. That’s a fraction compared with what even a diminutive country will consume. But Sam Altman, CEO of OpenAI, has announced some plans that would absolutely radicalize the size of the game. By the last quarter of 2025, OpenAI is expected to hit 2 GW, almost 9x growth in less than a year.
That’s not the end goal. The company’s long-term ambition? To reach 250GW of energy capacity by 2033—a bombshell year-over-year jump of 125x in just over ATDecade (8 years). If it’s achieved, it could surpass whole nations’ carbon footprints, including India’s current capacity of 223 GW.
This article goes deep on OpenAI’s energy roadmap, worldwide comparisons, growth challenges and what all that expansion means for the future of AI, energy and sustainability.
The 2025 Growth – From 0.23 GW to 2 GW
By the early months of 2025, OpenAI’s total energy use amounted to 230 megawatts (0.23 GW). There was already at least one conspicuous consumption level for a tech company. But with an explosion of ever more powerful A.I. models, each of which consumes tens of thousands of GPUs on their own, the curve is steep.
OpenAI plans to grow capacity to 2 GW by the end of 2025. That’s almost nine times higher than at the beginning of the year. To put this in perspective, 2 GW is sufficient to power a city of several million people.
The primary driver of this exponential growth is the increasing appetite for AI services. With AI being adopted by businesses of all sizes to consumers using AI assistants in their daily lives, the compute demand is increasing. Every AI request, every training cycle and live response consumes electricity; that amount of energy becomes astronomical when you multiply it by billions of daily interactions.
This 2025 bump is just the first step in OpenAI’s longer-term plan. The company is primed for exponential growth that will be sustained year over year.
OpenAI’s Long-Term Goal – 250 GW by 2033
For the years after 2025, OpenAI has an ambitious goal: to achieve 250 GW energy capacity by 2033. To put this in perspective, consider India, one of the world’s largest and fastest-growing economies, which currently has a total capacity of about 223 GW. OpenAI alone could surpass that level of consumption in as little as 8 years.
The growing projection reads as an average annual multiplier of 1.8x This isn’t linear — this is exponential scaling facilitated by the emergence of generative AI, robotics, and potentially Artificial General Intelligence (AGI).
At 250 GW, OpenAI would be one of the few single largest consumers of energy on the planet. For perspective:
United States: ~488 GW
India: ~223 GW
Germany: ~57 GW
United Kingdom: ~35 GW
Singapore: ~6.5 GW
With even OpenAI’s expansion, it would still be equivalent to the energy footprint of a major country. It would be the first tech company to challenge countries in electricity usage.
Why Does AI Need So Much Energy?
A question I often hear is: why does AI need so much electricity? And it all comes down to computational scale. Training large language models (LLMs) requires running trillions of computations on thousands of high-performance GPUs or even specialized chips.
For example:
One single large-scale AI model can consume electricity by the megawatt-hour.
The demand for AI when deployed in billions of users across the globe increases by an order of magnitude.
Every click on your AI assistant connects back to massive data centers that require 24/7 uptime.
And it’s not just training models: OpenAI is constantly refitting them, testing the safety of running them and scaling up infrastructure to deploy them. Tack onto that cooling systems, server maintenance, and redundancy and the energy needs go through the roof.
And as AI approaches Artificial General Intelligence (AGI), the computation—and hence, energy—requirements are only projected to go up. OpenAI’s 250 gigawatt target isn’t just ambition — it’s what is absolutely necessary to maintain the pace of this innovation.
Global Energy Comparisons – OpenAI vs Countries
Let’s put OpenAI’s 2033 goal in perspective by comparing it to countries:
United States (488 GW): Still comfortably out in front, though OpenAI’s 250 GW would be over half of the US’ total.
India (223 GW): OpenAI would exceed India’s total energy use right now.
Germany (57.7 GW): OpenAI’s request would be over 4x the capacity of Germany.
United Kingdom (35.3 GW): Approximately 7x larger than the UK’s entire capacity.
Singapore (6.55 GW): OpenAI would nearly 38x smaller than Singapore’s demand!
These comparisons also serve as a reminder that OpenAI’s energy footprint is not just a problem for one company; it’s an issue for the world. There are few, if any, private companies that require infrastructure at this scale. If OpenAI meets its goal, it would represent a stunning exception to the rule that most commercial technology companies have nowhere near the energy consumption of some countries.
The Challenges – Sustainability and Infrastructure
250 GW cannot be done through ambition alone, but through breaking down enormous challenges. The two biggest hurdles are:
Infrastructure
It is a Herculean endeavour to build enough data centres and secure power supply. Each new facility needs land, cutting-edge chips, cooling systems and secure flows of energy. For a private company to operate this at national scale is unprecedented.
Sustainability
The ecological aspect is also acute. A 250GW energy footprint could be very impactful if used irresponsibly, especially in terms of carbon. This is why OpenAI and other AI-focused companies are increasingly striking partnerships in renewable energy — solar, wind, hydro and nuclear included — to power their data centers.
Public scrutiny is also growing. Governments, regulators and environmental groups are asking whether such enormous energy consumption is morally justified — more than ever. OpenAI would need to make transparency and sustainability central to its effort, if it is to retain global backing.
What This Means for the Future of AI
If OpenAI realizes 250 GW of capacity by 2033, it would be a game changer for the technology. The implications include:
Acceleration of AI More Broadly: With virtually unlimited energy, OpenAI would be able to train and deploy systems in ways nobody could currently predict.
Tectonic Shift in Global Energy: As nations take strong stances on sustainability, countries might reconsider their own energy policies knowing tech giants consume as much as small nations.
Push for Renewables: There may be such huge demand that the coveted clean energy and nuclear power end up fast-tracked.
AGI Readiness: Increasing energy availability helps us work toward Artificial General Intelligence (when machines can think and reason like humans), moving humanity closer to AGI.
In short, OpenAI’s announcement to scale energy capacity 125x in just 8 years is more than a corporate milestone — it’s a global event. Demonstrating the confluence of technology, infrastructure and sustainability that shapes the future. Whether this odyssey bears fruit or not, the world will be watching.
