Clean energy adoption rises amid Iran war conflict

The conflict involving Iran has prompted more than 30 governments to implement policies aimed at improving energy efficiency or transitioning away from fossil fuels. While the spike in oil and gas prices following the start of the war in February has encouraged renewable energy adoption, experts suggest these efforts are currently insufficient to combat climate change.

Global greenhouse gas emissions have seen a slight increase, and investments in clean energy declined in the first half of 2026 compared to the previous year. According to the Rhodium Group’s Clean Investment Monitor, China accounted for much of this global decline. However, regional trends vary; solar investment grew in the United States, Europe, and India, while wind investment remained stable or grew in those areas.

In the United Kingdom, solar installations have surged despite government considerations for expanding natural gas production. In Indonesia, solar power is replacing some diesel plants, though the country continues to rely on coal for heavy industries. Experts note a contradiction in global policy, as governments attempt to acknowledge the importance of clean power while simultaneously supporting fossil fuel expansion.
