Vejroe, an idyllic island without fixed connections to the mainland via cables or regular transport, has long required a more sustainable energy solution. Previously, the island depended on diesel generators, which meant large quantities of diesel had to be transported to Vejroe—an impractical and costly solution. This created a strong drive to transition to self-sufficient and sustainable solutions for energy and heating. 

To meet the goal of becoming energy self-sufficient, Vejroe has implemented an innovative plan. Two household wind turbines , solar panels, and large batteries have been installed to efficiently harness and store renewable energy. These technologies form the cornerstone of Vejroe’s transition to greener energy sources. 

Vejroe is now clearly on the path to 100% renewable energy. The island’s energy needs are met by an off-grid system powered by two wind turbines from Viking Wind and solar panels with a combined capacity of 90 kW. Additionally, the energy is stored in a large battery with a capacity of 207 kWh. The goal is to entirely eliminate the need for diesel generators, marking a milestone in the island’s sustainability efforts. 

Next Steps 

The transition to renewable energy also involves improvements in Vejroe’s heating supply. Already, some of the heating is generated through solar collectors and geothermal heating. The plan is to store hot water during periods of abundant sunshine and wind, so it can be utilized optimally. Future projects will focus on optimizing the use of water resources to ensure that high-quality drinking water is not wasted in toilets.
