The primary obstacle to Africa's energy transition is not the declining cost of clean technology, but the elevated cost of capital. While solar plants in regions like the Sahel and southern Spain utilize similar, affordable equipment and Africa boasts superior solar potential, financing costs make African projects uneconomic compared to their European counterparts.

Renewable energy is heavily capital-intensive, with upfront construction costs recouped over decades, making electricity prices highly sensitive to financing terms. Expensive capital renders projects unviable, a situation exacerbated in Africa by a combination of sovereign and macroeconomic risks, currency fluctuations, concerns over the creditworthiness of utility off-takers, and liquidity risks due to shallow domestic markets.

Existing climate finance initiatives often fall short because they fail to address these risk structures. More capital alone is insufficient; innovative instruments like guarantees, blended finance structures, and predictable revenue frameworks are needed to lower debt costs. Redirecting domestic capital from government securities to infrastructure faces the same risk-pricing challenges. Ultimately, Africa's financial system must improve its ability to price and channel long-term risk affordably to unlock its vast solar potential.
