Solar energy has officially been declared the fastest-growing source of electricity generation in human history by the International Energy Agency (IEA). In their latest report, the agency confirmed that solar installations grew by a record 50% in 2025, driven by plummeting costs and surging demand across every continent.
The cost of solar panels has dropped an astonishing 90% over the past decade, making solar energy cheaper than coal in most markets worldwide. China led the charge, installing more solar capacity in a single year than the rest of the world combined, while countries across Africa and Southeast Asia are experiencing their own solar revolutions.

Experts predict that solar will become the single largest source of electricity globally by 2030, overtaking coal and natural gas. The rapid growth is also creating millions of green jobs worldwide, from manufacturing to installation and maintenance, offering economic opportunities alongside environmental benefits.
