Ruhnu is a small island. The island plans to use only renewable energy by 2030. Currently, the island uses diesel generators. Diesel has to be transported to the island.
The head of the Estonian Islands Energy Agency, Sulev Alajõe, says that Ruhnu can become diesel-free. Using renewable energy is possible. Ruhnu and Saaremaa have participated for four years in the "Clean Energy for EU Islands" program. The goal of the program is to help islands use only renewable energy by 2030.
Alajõe says that Ruhnu can use more wind energy. Battery usage is also important. On sunny and windy days, electricity can be stored. It can then be used later when there is no wind or sun. The diesel generator would remain only as a backup.
Currently, Ruhnu cannot implement this solution. There is insufficient capacity. Alajõe mentions that discussions with the government about using renewable energy are ongoing. It is technologically feasible. The central government must approve it. It requires investments, but they will pay off.
If the plan works, Ruhnu will no longer need to transport diesel. The island can become independent of diesel. This would be good for the environment and the island's residents.
