The world’s energy supply remains heavily dependent on fossil fuels, which produce 81 percent of global energy, according to an analysis published by Al Jazeera. The report examines how the Iran war is affecting that supply and the wider consequences for global energy markets.

Central to the analysis is the Middle East’s role in producing and supplying the world’s energy. The region has long been a key source of fossil fuels, and Al Jazeera’s charts set out the extent of that role in the context of the ongoing conflict.

The report also considers what happens when supplies are cut, a scenario with potential implications for energy availability and prices around the world. The visual analysis is intended to illustrate the scale of global reliance on the region.

With fossil fuels accounting for the overwhelming majority of global energy, disruptions to supply from a major producing region can reverberate across markets. Al Jazeera’s presentation of the data underscores how dependent the world remains on these sources.

The piece arrives as attention focuses on the Iran war and its effects beyond the immediate region, including on economies and consumers that rely on steady energy flows.
