Global energy investment reaches a record three point four trillion dollars in 2026, according to the International Energy Agency. Clean energy technologies, including solar, wind, grids, and nuclear, attract two point two trillion dollars, while fossil fuels receive one point two trillion. The surge is driven by mounting energy security fears following the Strait of Hormuz closure and the Ukraine war's lasting impact. Solar energy alone draws three hundred and sixty-five billion dollars, confirming its dominance as the world's fastest-growing power source.
