Renewable Stocks Were Supposed to Be Long-Term Winners. Higher Rates Are Testing That Bet
Renewable energy may run on sunshine, but it was built on cheap capital. Higher borrowing costs are exposing just how dependent the industry became on it, dragging renewable stocks into the same rate-sensitive slump that has hit real estate and utilities. And the pain is showing up fastest in names investors thought were built to weather it.
Front-loaded and exposed: Renewable projects burn through cash long before they generate any, with developers paying for equipment, permits, and construction before a solar or wind farm starts producing power. That makes financing a huge part of the economics. Wood Mackenzie estimates that a 2 percentage point increase in the risk-free rate raises lifetime costs by 20%, compared with 11% for a natural gas plant.
- The 10-year Treasury yielded 5.2% Friday, up a full percentage point in seven months and keeping financing costs elevated across the sector.
- Solar stocks are feeling the squeeze, with SunPower down 76% over six months and residential solar lessor Sunrun off 38%.
Where The Funds Are Going Instead
Equipment makers are getting caught in the selloff too, with First Solar, SolarEdge, and Enphase all declining recently. Capital is moving elsewhere as well. Imports of China-made solar systems peaked above $5.8B a month in March 2023 but have averaged $2.7B in 2026. Utilities are spending more on grids, storage, and transmission instead, building out the infrastructure needed to get more from the renewable capacity already installed.
- Importers paid ~$75B for Chinese batteries and grid equipment in the first seven months of 2026.
- NextEra Energy says it added more than $46B of hedges built to absorb interest-rate swings.
The long replacement cycle: Aging fleets should eventually give the industry a lift that higher rates can’t erase. More than 3.5 TW of wind and solar capacity is already operating globally, while 2.5 TW of projects will reach the end of their lives by the 2040s. Replacing them will drive another wave of spending, with Wood Mackenzie expecting equipment sales volumes to be more than 60% higher in 2050 than in 2026. That gives the industry a long runway for demand, but does little to solve the financing squeeze investors are pricing in today.
