Why Your Car Insurance Bill Is Making Renewables More Expensive

The Fed on Wednesday issued a report showing substantial increases in the price of eggs, used cars, and auto insurance — data that could spell bad news for the renewables economy.

Though some of those factors had already been widely reported on, the overall rise in prices exceeded analysts’ expectations. With overall inflation still elevated — reaching an annual rate of 3%, while “core” inflation, stripping out food and energy, rose to 3.3%, after an unexpectedly sharp 0.4% jump in January alone — any prospect of substantial interest rate cuts from the Federal Reserve has dwindled even further.

Renewable energy development is especially sensitive to higher interest rates. That’s because renewables projects, like wind turbines and solar panels, have to incur the overwhelming majority of their lifetime costs before they start operating and generating revenue. Developers then often fund much of the project through borrowed money that’s secured against an agreement to buy the resulting power. When the cost of borrowing money goes up, projects become less viable, with lower prospective returns sometimes causing investors not to go forward .

High interest rates have plagued the renewables economy for years. “As interest rates rise, all of a sudden, solar assets that are effectively bonds become less valuable,” Quinn Pasloske, a managing director at Greenbacker, a renewable investor and operating company, told me on Tuesday, describing how the stream of payments from a solar project becomes less valuable as rates rise because investors can get more from risk-free government bonds.

The new inflation data is “consistent with our call of an extended Fed pause, with only one rate cut in 2025, happening in June,” Morgan Stanley economists wrote in a note to clients. Bond traders are also projecting just a single cut for the rest of the year — but not until December.

Federal Reserve Chair Jerome Powell told the Senate Banking committee Tuesday, “We think our policy rate is in a good place, and we don’t see any reason to be in a hurry to reduce it further.”

The yield for the 10-year Treasury bond, often used as a benchmark for the cost of credit, is up 0.09% today, to 4.63%. While this is below where yields peaked in mid-January, it’s a level still well above where yields have been for almost all of the last year. When Treasury yields rise, the cost of credit throughout the economy goes up.

Clean energy stocks were down this morning — but so is the overall market. Because while high interest rates are especially bad for renewables, they’re not exactly great for anyone else.
