1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Relative to fossil fuels, the cost of renewables is more sensitive to the cost of capital (CoC). Here, we analyze the impact of changing financing costs on the competitiveness of renewable power. Following a decade of low rates, interest rate rises occurred in developed and developing economies from 2022. In the U.S., this added 9% to the levelized cost of electricity (LCOE) of combined cycle gas turbines, compared to 18% for solar photovoltaics (12% with tax credits). At present, reductions in CoC would have limited impact on competitiveness in Europe, given high fuel and carbon prices, but in the U.S., China, and India, reductions can facilitate convergence in LCOE between certain renewable technologies and lower-cost fossil fuel power. Consequently, policies reducing renewable CoC can accelerate cost parity with fossil fuels. However, policies that increase fossil fuel CoC are less effective, given the lower sensitivity to financing costs.
