The ongoing conflict in Iran is reshaping the global energy landscape, accelerating the shift from fossil fuels to clean energy alternatives. As tensions rise, countries are experiencing soaring oil prices, prompting emergency measures. The International Energy Agency has noted that nearly 40 countries are responding to this crisis, with some implementing drastic changes like shortening school weeks in Laos and adjusting cooking gas supplies in Nepal. In high-income nations like the UK, the economic impact is severe, while developing countries face catastrophic energy costs. This crisis is reminiscent of the 1970s oil shocks, which led to increased fuel efficiency and a push for nuclear energy. Today, alternatives to fossil fuels are more accessible and affordable, with electric vehicle demand rising sharply—51% higher in Europe compared to last year. Countries are now looking to build renewable energy capacity rapidly, as seen in South Korea's urgent call for a transition to clean energy. India is also making strides, with solar power accounting for 9% of its electricity generation, up from just 0.5% a decade ago. The shift towards renewables is expected to benefit countries like China, which leads in solar and battery manufacturing. Ultimately, the Iran conflict highlights the vulnerabilities of oil dependency and the urgent need for a sustainable energy future.
