Solar panel prices have fallen 90 percent since 2010, making solar the cheapest form of energy on Earth. Early German subsidies and Chinese manufacturing scale-up set off a cost spiral that still drives 80 percent of the global solar supply chain today.
Energy security, not climate policy, is now the biggest driver of adoption, with even the Trump administration overseeing record US solar growth.
Solar power is far and away the world’s fastest-growing form of energy production, beating out every other form of energy on Earth in 2025.
China still dominates the solar manufacturing sector today, controlling a whopping 80 percent of global supply chains.
This rapid decline in costs has evolved thanks to early policy pushes from two vastly different economies and governments – China and Germany.
Solar power is no longer a matter of climate policy – it’s a matter of energy security and simple economics.
