Iceland stands as a global leader in renewable energy, powering nearly 100% of its electricity and 85% of its total primary energy from hydro, geothermal power, and wind. This impressive achievement stems from Iceland’s bountiful renewable resources and a long-term commitment to self-sufficiency and innovation. Originally born out of necessity as farmers sought efficient ways to heat homes and access hot water in the early 1900s, Iceland’s transition to renewables has been buoyed by a culture of collaboration, experimentation, strategic investments, and a clustering approach. Today, the country’s renewable infrastructure encompasses electricity generation, heating, aluminum smelting, and novel projects like carbon dioxide (CO₂) capture and storage. Iceland’s national and municipal governments play a central role, owning major energy companies that balance economic and environmental priorities while fostering partnerships among stakeholders. Looking ahead, Iceland aims to achieve net zero by 2050. To attain net zero, the country will need to adapt to emerging technologies, shifting global energy dynamics, and stricter environmental standards while enabling debates on balancing economic growth with environmental protection through transparency, inclusivity, and strong governance. Iceland’s energy story offers valuable lessons to other countries striving to make the transition to renewable energy.
