Energy is the universal currency of physics. Every computation requires energy. Every material transformation requires energy. Every form of work, biological or mechanical, requires energy. Civilization is fundamentally an energy-processing system.
The history of human progress is largely the history of energy capture: fire, agriculture, fossil fuels, nuclear fission. Each energy transition unlocked new capabilities and supported larger populations at higher standards of living.
We are approaching another transition, potentially the most significant in history: the transition to energy abundance.
The Current Constraint
Modern civilization runs on fossil fuels. Despite decades of renewable energy development, oil, coal, and natural gas still provide roughly 80% of global primary energy. This dependency constrains everything.
Fossil fuels are finite. They are geographically concentrated, creating geopolitical tensions. Their extraction and combustion cause environmental damage. Their energy density is fixed by chemistry.
More fundamentally, fossil fuel energy is scarce. Not scarce in the sense of immediate shortage, but scarce in the sense that energy costs money, that more energy requires more extraction, that energy use must be rationed and economized.
Every economic activity incorporates energy costs. Every technology that requires significant energy is limited by that requirement. Desalination could provide unlimited fresh water, but it requires energy. Carbon capture could reverse climate change, but it requires energy. Vertical farming could feed unlimited populations, but it requires energy.
The constraint is energy, not technology.
The Path to Abundance
Several technologies could provide energy abundance. Each has challenges, but none faces fundamental physical barriers.
Fusion. The sun is a fusion reactor. Replicating controlled fusion on Earth would provide effectively unlimited clean energy from hydrogen, the most abundant element in the universe. After decades of development, fusion is finally approaching commercial viability. Projects like ITER, along with private ventures like Commonwealth Fusion Systems and TAE Technologies, are making rapid progress.
Fusion has always been "thirty years away," but the situation has genuinely changed. Advances in superconducting magnets, plasma physics, and AI-assisted design are accelerating development. The first commercial fusion plants could operate within two decades.
Advanced solar. Solar energy is already the cheapest form of new electricity generation in most locations. The sun delivers more energy to Earth's surface in an hour than humanity uses in a year. The challenge is intermittency and storage.
But costs continue to fall, efficiency continues to improve, and storage technology advances. Space-based solar, which avoids weather and nighttime, could provide baseload power transmitted to Earth via microwave. Advanced solar alone could provide energy abundance, even without fusion.
Fission. Advanced nuclear fission, particularly small modular reactors and molten salt designs, could provide abundant energy without the problems that plagued earlier generations. Modern reactor designs are inherently safe, produce minimal waste, and can be deployed at scale.
Nuclear fission is not as unlimited as fusion, but uranium and thorium reserves are sufficient for centuries, and advanced fuel cycles can extend this further. Fission could bridge to fusion abundance.
Geothermal. The Earth's core is essentially unlimited thermal energy. Advanced geothermal techniques, including enhanced geothermal systems that work anywhere rather than just at natural hot spots, could tap this reservoir.
None of these technologies requires new physics. Each faces engineering challenges, economic challenges, regulatory challenges. But the path to energy abundance is visible.
What Abundance Enables
Energy abundance is not merely an environmental or economic goal. It is the prerequisite for civilizational transformation.
Desalination. With unlimited energy, fresh water becomes unlimited. Oceans cover 70% of Earth's surface. Desalination is energy-intensive but technically straightforward. Water scarcity becomes a solved problem.
Vertical farming. Agriculture currently uses 70% of fresh water and half of habitable land. Vertical farming in controlled environments could produce more food with less land and water, but requires significant energy for lighting and climate control. With abundance, food production becomes unconstrained.
Carbon capture. Atmospheric carbon dioxide can be captured and sequestered or converted to useful products. The technology exists; the limitation is energy cost. With abundance, we could not only stop emissions but reverse them, actively cooling the climate.
Materials synthesis. Any material can be synthesized given sufficient energy. Diamonds from carbon, rare earth elements from common elements, any molecular structure from basic atoms. Material scarcity becomes a matter of information (knowing what to build) rather than energy.
Computation. AI and computational infrastructure have enormous energy footprints. With abundance, computation becomes essentially free, enabling AI capabilities currently limited by power constraints.
Space access. The fundamental challenge of space travel is energy: lifting mass against gravity, accelerating to orbital velocity. With abundant energy, space becomes accessible. Manufacturing in orbit, lunar mining, Mars settlement become economically viable.
Energy abundance does not automatically solve every problem. It provides the foundation on which solutions can be built.
Economic Transformation
When energy becomes essentially free, the economy transforms fundamentally.
Most current economic activity involves transforming raw materials into useful products and transporting them to where they are needed. Energy is a major cost in both production and transportation. When energy cost approaches zero, the cost of physical goods plummets.
Labor costs are ultimately constrained by subsistence: workers must earn enough to pay for food, shelter, and energy. When these costs drop, the entire wage structure shifts. More abundance becomes accessible to more people.
The transition will be disruptive. Industries built on energy scarcity will become obsolete. Fossil fuel extraction, much of the transportation sector, energy-intensive industries will transform or disappear.
But the endpoint is a world of material abundance. Not infinite abundance; physical resources remain finite even with unlimited energy. But abundance sufficient that basic material needs are trivially met for everyone.
The Transhumanist Connection
Energy abundance connects directly to transhumanist goals.
Life extension requires energy: running hospitals, producing medications, powering research. Medical nanobots will require energy for their operations. Cryonic preservation and eventual revival require sustained energy over long periods.
Mind uploading requires computational infrastructure of enormous scale. Running uploaded minds, maintaining their continuity, providing them with rich simulated environments: all require energy. Without abundance, only a few could upload; with abundance, everyone could.
Space colonization requires energy at every stage: launch, habitat maintenance, life support, manufacturing. A solar system civilization requires capturing and utilizing energy at scales far beyond current use.
Intelligence enhancement through brain-computer interfaces and AI integration requires ongoing power. The cognitive revolution depends on the energy revolution.
Energy is not the goal. Transcendence is the goal. Energy is what makes transcendence possible.
The Political Dimension
Energy abundance is not merely a technical challenge. Powerful interests benefit from energy scarcity.
Fossil fuel companies profit from extraction. Petrostates derive geopolitical power from energy exports. Utilities profit from controlling energy distribution. Even renewable energy companies profit from selling energy rather than giving it away.
The transition to abundance threatens these interests. Resistance should be expected: lobbying, regulation capture, disinformation campaigns, artificial scarcity.
The right response is to accelerate development. The faster abundance technologies mature, the harder they become to suppress. Once fusion or advanced solar reaches cost parity and deployment scale, the transition becomes unstoppable.
I do not advocate government control of energy development. Markets, properly structured, will drive the transition. But we should be clear-eyed about the interests that oppose abundance and prepare to overcome their resistance.
Personal Conviction
I believe energy abundance will be achieved soon. Not as a distant hope but as an engineering trajectory already underway.
Fusion will work. Solar costs will continue dropping. Storage problems will be solved. The physics permits it; the engineering is progressing; the economics increasingly favor it.
When abundance arrives, it will transform everything. Not immediately, not uniformly, but comprehensively. The world I will inhabit in fifty years will be fundamentally different from the one I grew up in, not because of social change or political shifts, but because energy will no longer be a constraint.
This is worth working toward, worth investing in, worth accelerating by every available means. Energy abundance is the foundation for everything else we want to build.
The fusion reactors of 2040 will make possible the uploaded minds of 2060, the space settlements of 2080, the transcendent civilizations of the next century. It all starts with energy.
I am optimistic. The sun has always offered us abundance; we are finally learning to accept it.
