Using an unordered list, summarize the following article with between 4 and 8 key points. The rise of artificial intelligence (AI) use is drawing attention to a global energy supply bottleneck, which is affecting all kinds of industries.New approaches to energy supply aim to harness continuous solar energy from space, which could meet demand with existing infrastructure.Scaling promising ideas for impact is a key focus of the World Economic Forum’s Annual Meeting of the New Champions, also known as ‘Summer Davos’, in China from 23–25 June 2026.AI is forcing an urgent question onto the global agenda: Where will all the power come from?Tech executives are blunt about the current energy supply bottleneck. “Power is my problem today,” Microsoft CEO Satya Nadella said on a recent podcast. The scramble for power is already reshaping infrastructure decisions. Market intel firm Cleanview has identified 84 GW of proposed data centre projects that plan to deploy onsite gas-fired generation as developers rush to develop power sources. When companies are willing to deploy gas turbines just to get access to electricity faster, it becomes clear how valuable new sources of power could be.But data centres’ need for massive amounts of reliable, always-on power is colliding with slow grid expansion, transmission bottlenecks and the realities of building new infrastructure. Those same pressures will also come for the rest of the global economy in the years ahead.The scale of innovation has always depended on the scale of energy. Space now presents a critical new domain for energy access. Energy infrastructure in spaceFor decades, space infrastructure has quietly supported life on Earth through communications, navigation, weather forecasting, remote sensing and national security.Now space is expanding from being an information layer to become an energy layer as well. With mounting pressure on terrestrial infrastructure, new technologies can take advantage of continuous solar energy, one of space’s most abundant resources.Solar panels have become indispensable in space, powering satellites long before they became commonplace on Earth. Now, advances in launch, optics and manufacturing could make it practical for space to power EarthThe emerging orbital energy economyFor most of the commercial space era, the industry’s defining challenge was access to orbit. SpaceX has dramatically lowered the cost of reaching orbit, and now companies are shifting to creating meaningful value for Earth once they’re there. AI and energy demand are an urgent driver.Companies like Starcloud and SpaceX are exploring whether AI workloads should be co-located with the abundant energy in orbit. The appeal is obvious. Moving compute closer to a virtually continuous energy source could reduce dependence on increasingly constrained power infrastructure and siting environments.The tradeoff is that energy is only one part of the equation. Latency, thermal management, maintenance and hardware replacement are central problems to solve in the architecture. Cooling is a good example. Modern AI systems generate enormous amounts of heat and operating those systems in orbit introduces a different set of challenges than operating them on Earth.Bringing space solar energy back to EarthRather than relocating demand, space solar energy expands the supply of available energy on Earth by delivering power from space directly into terrestrial electricity systems.That creates opportunities to build on infrastructure that already exists. For example, Overview Energy is designing the technology to use utility-scale solar projects as receiving infrastructure. It collects energy in orbit and transmits it using safe, invisible, near-infrared light optimized for photovoltaic panels, allowing solar assets to generate electricity at any hour.Energy from orbit then flows into infrastructure that is already connected to the grid rather than requiring entirely new sites. That matters in a world increasingly obsessed with speed to power.The remaining questions are primarily industrial: how quickly these systems can be manufactured, deployed and scaled at the right price point.Data centres: The canary in the coal mineData centres are receiving most of the attention right now, but economies will continue to need more reliable electricity for other uses. Advanced manufacturing, industrial electrification, desalination, hydrogen production and future digital infrastructure will all require abundant electricity. And access to power shapes what gets built and where.The industry has spent the last decade building a huge amount of renewable infrastructure. The largest hyperscalers alone have contracted roughly 30 GW of solar capacity. Today, those assets generate electricity only when sunlight is available.That’s one of the most compelling parts of delivering energy from space straight to solar projects. Instead of building an entirely new class of energy asset, you increase the utilization of one that already exists. A solar project that generates power for more hours of the day produces more energy, creates more value for the grid and improves the economics of infrastructure that has already been built.Innovating at scaleEvery major wave of innovation eventually encounters physical constraints. Energy is the constraint of our era. Meeting that challenge will require expanding access to reliable power in ways that were difficult to imagine even a decade ago.For decades, space infrastructure has helped move information around the world. In the future it will move energy.The Forum is spotlighting how innovation moves from breakthrough to scale to impact ahead of ‘Summer Davos’ in China, 23–25 June 2026. Follow the latest.
