The era of ever-cheaper clean power is over, giving a fresh jolt of uncertainty to global energy markets battered by one supply crisis after another.

Relentless price declines over the past decade made renewables the cheapest sources of electricity in much of the world. In the past year, though, prices for solar panels have surged more than 50%. Wind turbines are up 13%, and battery prices are rising for the first time ever.

As pandemic-induced supply delays ensnare everything from cars to salads, green energy’s price hikes may not come as a surprise. But shipping backlogs and commodities shortages are coming at a particularly vulnerable moment for wind and solar. After years of rapid-fire advances in technology and manufacturing, there are fewer opportunities left to cut costs without sacrificing profits. Instead of perpetually falling, prices will now ebb and flow based on the cost of raw materials and other market forces.
