The Best Sight in Hveragerði, Reykjanes Peninsula and the South Coast (with the Golden Circle)

All of Iceland's electricity comes from renewable sources and 90% of Icelandic homes use geothermal water for heat. If you are interested in seeing how this sustainable energy system works, you should visit the Geothermal Energy Exhibition at the Hellisheiði Power Plant, the largest single-site geothermal unit in the world. People of all ages can learn about geothermal utilization via interactive installations and displays. Afterward, you can check out the gift shop and take in the moonlike landscape while enjoying some treats at the on-site café.
