A recent analysis compares how Italy and Chile are pursuing carbon neutrality by 2050. Chile's shift is driven by cheap solar and wind in the Atacama, with market rules that dispatch the lowest-cost generation. Italy relies more on EU mandates and energy security concerns, but both countries face similar bottlenecks: transmission buildout, storage deployment, and permitting delays. The article highlights key differences in consumer outcomes. In Chile, renewable entry has lowered wholesale prices, while Italy still has Europe's most expensive retail electricity despite massive renewables. Carbon pricing plays a limited role in both power sectors, with technology costs and market structure mattering more. For anyone tracking grid decarbonization, the shared lessons are clear: generation is no longer the main constraint. Transmission, storage, and cost of capital are what will decide how fast these transitions actually move.
