These multi-source systems could become the norm in countries with limited land availability, ensuring a stable and diversified renewable supply.
Geothermal and Bioenergy: Turning Waste into Power
In geothermal, Iceland’s Hellisheiði plant captures CO₂ and stores it as rock—a process called CarbFix.
This dual approach generates power while actively reducing atmospheric carbon.
Kenya’s Olkaria Geothermal Field, the largest in Africa, now supplies 30% of the country’s electricity, with plans to expand to 1,600 MW by 2030.
Enhanced geothermal systems (EGS), like those being tested in Utah’s FORGE lab, could unlock geothermal potential even in regions without natural hotspots.
Bioenergy takes a futuristic turn with Germany’s ALG-AD project, converting agricultural waste into biogas via algae.
It’s a closed-loop system, turning pollution into power without farmland competition. Sweden’s GoBiGas plant has successfully produced biomethane from forestry residues, feeding it directly into the national gas grid.
Meanwhile, California’s LanzaJet facility produces sustainable aviation fuel (SAF) from ethanol derived from agricultural byproducts, reducing airline emissions by up to 70%.

The circular economy is driving bioenergy’s evolution. Companies like Finland’s Fortum are using waste-to-energy plants to power district heating, achieving near-zero landfill rates.
These projects prove that bioenergy isn’t just about replacing fossil fuels—it’s about reimagining waste as a resource.
Ocean and Space-Based Energy: The Next Frontier
Wave energy gains traction with Australia’s CETO 6, harnessing ocean currents to produce electricity and desalinated water.
Its submerged buoys avoid visual pollution, making it coastal-friendly. Portugal’s Aguçadoura Wave Farm, the world’s first commercial wave energy project, has demonstrated reliability even in rough seas.
The U.S. Department of Energy’s PacWave South facility, set to launch in 2025, will test next-gen wave converters at a 20 MW scale.
Tidal energy is also surging. Scotland’s MeyGen project, the largest tidal stream array, has delivered 50 GWh since 2016.
France’s upcoming Normandie Hydro project will deploy underwater turbines capable of powering 250,000 homes.
Unlike wind and solar, tidal energy is perfectly predictable, offering baseload potential for grids struggling with intermittency.
Space-based solar, championed by ESA’s SOLARIS, explores beaming energy from orbit.
Though experimental, it could provide uninterrupted power, unaffected by weather or nighttime.
Japan’s JAXA has already tested microwave-based power transmission, while the U.S. Air Force’s SSPIDR project aims to deploy a working prototype by 2027.
The biggest hurdle remains cost—but with SpaceX reducing launch expenses, orbital solar farms may soon be economically viable.
Solar Innovation and Green Hydrogen: Beyond Traditional Limits
Solar windows, like those from Ubiquitous Energy, transform buildings into power generators.
