Can Humanity Become A Type 1 Civilisation?
As humans, we take immense pride in our civilisation. We flaunt towering skyscrapers, great monuments classified as architectural marvels, developed cities, and so much more. We have split the atom, landed on the Moon, created technology that would seem magical just 70 years ago, and yet, on the Kardashev Scale, humanity has not reached the status of even a Type 1 civilisation. Why are we so far from this milestone? And could we ever reach it?
What is the Kardashev Scale?
In 1964, Soviet astronomer Nikolai Kardashev proposed a scale for classifying a civilisation based on its energy consumption. The logic was that the more energy a civilisation could harness, the more technologically advanced it would be. A Type I civilisation would harvest all available energy on its planet and make use of it efficiently. A Type II civilization would extend this capability to harness the energy of its home star and planetary system, potentially constructing theoretical megastructures such as Dyson Spheres. A Type III civilisation would be able to control its entire galaxy with resources immense enough to construct hypothetical structures such as the Matrioshka Brain or Shkadov Thrusters, all of which lie far beyond our current technological capabilities. They could potentially use multiple energy-harvesting systems across stars or harness energy from a black hole – a concept that is purely hypothetical today. A Type IV civilisation would be capable of harnessing the energy of an entire universe, granting abilities that transcend our current understanding of physics and technology. A Type V civilisation could control multiple universes, maybe even create them. Some physicists speculate the existence of Type VI or VII civilisations – so advanced they could control dark matter, spacetime, and the multiverse, their capabilities would feel godlike to us.
Originally, the Kardashev Scale consisted only of Types I, II, and III, making it difficult to determine humanity's precise position on the scale. So, a renowned astronomer, Carl Sagan, refined the scale by introducing decimal values based on the energy consumption of civilizations at each stage, making classification more precise. He calculated a Type I civilisation to use 1016 watts, with each civilisation increasing by ten orders of magnitude, placing Type II at 1026 watts (roughly the total energy output of the Sun), Type III at 1036 watts (roughly the total energy output of the entire Milky Way), and so on. To put this in perspective, humanity currently uses just 19 x 1012 watts, meaning we would need to increase our usable energy by hundreds of times before reaching Type I status. Hence, on this scale, humanity is currently ranked at about 0.7-0.75.
We have altered our planet, made significant changes to our environment and climate, and harvested immense energy from various sources. Yet we are still a few hundred years away from reaching the milestone of a Type I civilisation, estimated to be achieved around 2333 - 2404 at the current rate of advancements. That is, if we survive long enough.
What Does It Really Mean To Be A Type I Civilisation?
A Type I civilisation would be able to control its entire planet and would be looking to expand further in its solar system. While the Kardashev Scale is based solely on energy consumption, many futurists speculate that a civilisation with access to such vast energy reserves would have overcome all internal conflicts over land, end poverty and other social barriers, and be extremely efficient with its resources and energy systems. Such a civilisation would have heavily altered the planet with massive structures, mined entire mountains, and may even be able to rearrange the geographical features of their world, such as rivers and deserts. It would have the power to change the composition and temperature of its atmosphere and would be able to survive huge natural disasters using technology we currently dream of.
This type of civilisation would probably rely on futuristic energy systems such as fusion power or highly efficient solar panels, using clean power sources and minimizing waste or loss of energy. They would have made serious breakthroughs in technology, like AI, and would use it heavily to increase system efficiency and take care of mundane tasks. It would start looking to leave its home planet and colonise other planets in its solar system in a hunger for more resources. It would work towards constructing bases on the Moon or Mars, or build orbital settlements to mine asteroids. It may even start considering the construction of a Dyson Sphere to work towards becoming a Type II Civilisation.
Why Is Humanity Not A Type I Civilisation Yet?
Humanity still has a long way to go before becoming a Type I civilisation. For more than 90% of our existence, we have remained hunter-gatherers. Just 200 years ago, we stopped using human labour as the primary source of energy, and we have had the technology to communicate over large distances for barely a century. It took us 200,000 years to progress from living in caves to a complex civilisation. On the galactic scale, we are still embryos.
A Type I civilisation is expected to harness approximately 10^16 watts of energy, and while our energy consumption has grown 25 times between 1800 and 2026, we are still far from that threshold. We are still dependent on non-renewable resources for energy, such as fossil fuels, which also bring harm to our environment. Not to mention, our energy efficiency is very low; out of roughly 173,000 terawatts of solar energy from the sun being received every moment, humanity only utilises a tiny fraction. There are significant losses of energy during generation, transmission, and consumption due to technological limitations. To be able to power every home, vehicle, factory, data centre, spacecraft, and future colony using clean, sustainable energy while minimising waste, we would need revolutionary breakthroughs in energy storage, fusion power, global electrical infrastructure, and perhaps technologies we have not yet discovered.
Another major issue is the side effects of development threatening our planet, the most prominent being climate change. To become a Type I Civilisation, we must first overcome challenges like these before we end up destroying our own planet in our hunger for energy.
But the biggest challenge of them all is political and social issues such as war amongst countries, racism, sexism, poverty, discrimination, etc. Resources are not equally divided amongst countries, all genders and races still don’t get equal respect, and we still look down on others instead of pulling them up. We are still learning how to live in harmony, how to work together as a unified species and not as indifferent units. And despite having made immense progress compared to just a century ago, we still have a long road ahead of us.
How Could We Reach Type I?
Our world is still plagued by countries fighting over disagreements, with this unending race to be better than everyone else, with us working against each other instead of for each other. Every nation wants to be the first to land on the moon, the first to build a lunar base, the first to achieve something no one else has, but the truth is, to actually use our planet’s resources efficiently, to one day become a type I civilisation, we need to stop competing. Stop trying to one-up each other. Stop putting others down to feel superior. This milestone can only be achieved with collaboration amongst all of humanity, not just a few. But despite our conflicts, humanity has already shown that global cooperation is possible. Projects like the International Space Station, multinational fusion research, and worldwide climate agreements demonstrate that nations can work together when faced with challenges too large for any one country to solve.
And together to progress further, we must focus on finding ways to generate large amounts of energy while reducing waste and keeping our atmosphere clean and safe. Currently, nuclear fusion is considered one of the most promising candidates for providing the enormous amounts of clean energy required by a future Type I civilisation; scientists worldwide are working to create a viable, stable fusion power plant. We would also want to increase our efficiency in capturing solar power, possibly increasing the efficiency of solar panels or setting up space-based solar energy collection systems. Unlike ground-based solar panels, orbital solar arrays could collect sunlight almost continuously without interference from weather or the Earth's day-night cycle, potentially transmitting energy back to Earth using microwaves or lasers. We would have to find a way to use all this power efficiently with minimum loss, preferably through AI-based optimization systems and global energy networks, ensuring that energy is distributed efficiently and equitably across the globe.
It is estimated for us to reach the status of a Type I civilization by 2333-2404, but such estimates are based on the current rate of technological advancements. If commercially viable fusion power became widespread by the end of the 21st century, humanity could make a significant leap on the Kardashev Scale, potentially reaching around 0.77 depending on global adoption and energy demand. But if we regress and slow down due to internal conflict, this number may remain just a dream.
The Great Filter: Will Humanity Last Long Enough?
Ever since we have gained enough knowledge to know about the universe, philosophers and scientists alike have wondered, are we truly alone? Is there truly no life outside of Earth? Are we the first? Or one of many? This question led us to the very making of the Kardashev scale, to imagine what other civilisations would look like if they existed. But it also led us to another theory: The Great Filter.
The Great Filter refers to an impossible challenge that any civilisation has to overcome to grow and expand further. A sort of barrier that is extremely hard to overcome and leads to the death of most civilisations. There are two cases in this theory, the first is that the Great Filter is behind us – that life itself is extremely rare and our very existence is unique, that most lifeforms perish before becoming intelligent species with the ability to think. But the other case is that it is in front of us – an obstacle so dangerous it wiped out multiple civilizations before us. Scientists speculate it may be a natural disaster, an asteroid strike, or a nuclear war within us. A popular theory is that once a civilization is about to or has reached Type I status, it tends to self-destruct one way or the other, through war, disease, or any other disaster. If this case is true, then every silent star in the night sky may represent a civilisation that almost made it.
Conclusion
This brings us back to our original question – will we ever be able to become a Type I civilisation? And truth is, we don’t know. Currently, we have no way of being sure of what will happen in our future. Great obstacles lie ahead of us, challenges including the very unity of humanity, and to overcome them, the only thing we can do right now is push towards a peaceful future and focus on improving the quality of life, finding cleaner sources of energy, and conserving our planet to prevent it from burning out before we even get the chance to reach our potential.
We often measure humanity through the monuments we build, the cities we develop, or the technology we create, but perhaps the true measure of humanity would be whether we learn to work together, protect our planet, and survive long enough to become something greater. Perhaps every civilisation begins by believing it has reached its peak, only to realise it has taken its very first steps. The journey to becoming a Type I civilisation has already begun. Whether we finish it is entirely up to us.
