World’s First Vertical Floating Solar Plant Begins Operating
The push for renewable energy requires innovative solutions, such as the world’s first vertical floating solar plant, which is now operating on an artificial lake, Lake Jais, in Bavaria, Germany.
Each segment requires only a narrow submerged base to secure the panels and allow controlled movement under wind and fluctuating water levels. The system is connected to the grid via a floating cable and a shore-based feed in point, minimising disruption to the lake’s ecosystem. The vertical orientation of the solar panels offers several advantages. The panels face east and west which increases morning and evening output, times when traditional solar systems produce less energy. The spacing between the panels also allows wind to pass through more easily, reducing wear and tear on the structure.
Like many other countries, Germany has thousands of artificial lakes from mining and quarrying activities, many of which sit idle after operations cease. Floating solar instillations on these artificial lakes provide opportunities for solar energy generation without occupying land. The Lake Jais vertical floating solar plant only covers 4.65% of the lake’s surface and environmental monitoring has shown no negative ecological impact since the installation. Findings suggest that vertical floating solar plants can coexist with aquatic ecosystems, with waterfowl observed creating nests on the floating sections and schools of fish observed gathering around the submerged sections. It also has the potential to be used to complement offshore wind farms, as wind and solar generation patterns often differ; combining both technologies could provide a more stable source of electricity.
Research still needs to be carried out across different climate and water conditions, with winter ice formation and extreme temperatures presenting potential challenges, but offshore floating solar could be an exciting new addition to the renewable technology field.
Wildlife Can Help Tackle and Mitigate Climate Change
Wildlife can help us tackle climate change. Studies examining the impact of wildlife’s natural behaviour has uncovered some fascinating results. For example, a study published in the science journal Nature found that just one forest elephant can increase the net carbon capture capacity of a forest by almost 250 acres. This is the equivalent of removing a year’s worth of emissions of 2,047 cars from the atmosphere.
Another study, by the World Federation for Animals, found that digging mammals help to trap leaf litter and increase soil nutrients as they dig their burrows, which helps to sequester more carbon. It also helps retain moisture in forests that are increasingly dry and vulnerable to more intense and frequent wildfires.
A study carried out by the University of Birmingham found that beavers are able to engineer riverbeds in ways which prevent carbon dioxide release into the atmosphere. By building dams, beavers flood stream margins, create wetlands and trap large amounts or organic and inorganic material, including carbon. In 2025, a family of beavers made headlines after building a dam exactly where authorities in the Czech Republic had been planning one, saving taxpayers around £1,000,000. As well as storing carbon, preventing it from entering the atmosphere, beaver dams also help mitigate the impacts of climate change. Beaver dams act as a firebreak, with beaver-dammed areas three times less affected by wildfires, and provide a natural flood defence, protecting surrounding areas.
Along with further research, to understand wildlife’s crucial role in shaping ecosystems and carbon capture, we also need more policies to safeguard and restore wild animal populations around the world.
Renewable Microgrids
Renewable microgrids are small-scale localised power networks that generate, store and distribute electricity from renewable sources such as wind, hydro and solar.
Popping up around the world, small communities design and build their own renewable microgrids. Although they initially require investment and funding, the microgrids provide reliable and cheaper energy for residents and shield them from price surges in response to global politics.
One example is Feldheim, a small village in Germany. Since 1990, local residents have come together to create a renewable energy microgrid, building a wind farm, biogas plant, solar plant and battery storage to generate and store green electricity in their village. Each household invested in the network, and they secured funding from state and EU grants.
Their microgrid now produces hundreds of millions of kWh of electricity every year, far more than the local population needs, with less than 1% being consumed by local residents. The remaining 99% is therefore able to be sold to the national grid, generating local revenue.
Similar renewable microgrids exist in other small communities around the world, such as Knoydart and the Isle of Eigg in Scotland and Kodiak Island in Alaska, demonstrating how this approach can work in different locations. But this approach relies on good communication and community trust and investment to work, so scaling this approach to larger communities would be more challenging.
