Across the Middle East, families have endured fear, uncertainty and violence. Communities have faced disruption, displacement and the destruction that war brings. Protecting lives must remain the immediate priority. Yet, whatever happens in the coming days and weeks, the broader lesson will remain. The conflict has exposed a structural vulnerability in the global economy: as long as countries depend on fossil fuels, instability anywhere can create economic pain everywhere. It has also highlighted something else: the transition to decentralised renewable energy is increasingly a matter of economic security and resilience. As executive director of Greenpeace International, I regularly speak with colleagues across our global network who have described to me how the impacts of the US-Israel war on Iran are felt worldwide. In East Asia and Southeast Asia, the closure of the Strait of Hormuz has driven up fuel costs, inflation and pressure on household budgets in economies heavily dependent on imported oil and gas. Across Africa and Latin America, rising fuel prices have placed an additional burden on already impoverished communities. In Europe, North America and Australia, higher energy expenditures have affected transport costs, electricity bills and ultimately the price of everyday goods. This is fossilflation: the inflationary pressure created by an economic system that remains heavily dependent on fossil fuels. The more fossil fuel-dependent an economy is, the more exposed it is to disruptions far beyond its borders. The opposite is also true. Every increase in locally generated renewable energy reduces that exposure by weakening the connection between international crises and household costs, making countries more resilient and energy independent. The Organisation for Economic Co-operation and Development has warned that the Middle East conflict is driving rising inflation and weaker growth, with higher energy prices flowing through to transport, energy bills and consumer prices. It has also reported that governments in at least 46 countries have already introduced emergency measures to shield households and businesses from rising fuel costs. The International Monetary Fund, the World Bank and the World Food Programme (WFP) have warned that higher oil, gas and fertiliser prices are increasing food insecurity. Separately, the WFP has estimated that 45 million people could be pushed into acute hunger. What is often presented as an unfortunate consequence of geopolitics is, in reality, a feature of the fossil fuel system. The industry has become highly effective at exploiting the dynamics of conflict and energy shocks. Time and again, instability and price volatility have generated extraordinary profits for fossil fuel corporations. Analysis based on Rystad Energy data found that the world’s 100 largest oil and gas companies earned more than $30m an hour in windfall profits during the first month of the war. When crises expose the fragility of the system, the industry response is remarkably predictable: calls for more drilling, more pipelines, faster approvals, greater public subsidies and fewer environmental protections. The same crises that reveal the costs of fossil fuel dependence are used to justify deepening it. This is the fossil fuel playbook: turn disruption into profit, then use the disruption to argue for more of the system that created the vulnerability in the first place. The result is a cycle that leaves societies exposed to repeated economic shocks. Even worse, communities are made to subsidise the forces destabilising them. Even if this particular conflict subsides, the Strait of Hormuz remains open, and energy markets stabilise, the underlying risk remains. The next disruption could emerge from another conflict, another geopolitical confrontation, another supply constraint, or an extreme weather event. As long as economies rely on fuels traded through vulnerable global markets, households will remain exposed to forces far beyond their control. That is why the conversation should not end with ceasefires, shipping lanes, or short-term price movements. It should continue and focus on resilience. Renewable energy is often discussed primarily as a climate solution when it is increasingly an economic security solution as well. Every rooftop solar system, battery, electric bus, and energy-efficient building weakens the connection between geopolitical instability and household costs. Locally generated renewable energy cannot be blockaded, sanctioned or caught in the crossfire of international conflict. It reduces exposure to volatile fuel markets and strengthens energy independence. Countries that accelerate the transition to decentralised renewable energy systems will be insulated from future fossil fuel shocks. Those that remain dependent will continue to face recurring cycles of fossilflation. The lesson from the US-Israel war on Iran is that the economic insecurity created by fossil fuel dependence persists long after the headlines fade. Building a more peaceful, secure and resilient future requires more than ending individual conflicts. It requires replacing the energy system that allows crises in one part of the world to impose costs on people everywhere.
