Energy Efficiency and Electricity Reliability
在吉尔吉斯斯坦通过随机实验发现，变压器内节能灯普及率越高，停电次数越少，这种技术外部性惠及所有家庭，且节能灯采用中的溢出效应进一步降低用电量、提升可靠性。
Abstract Overloaded electrical systems are a major source of unreliable power. Using a randomized saturation design, we estimate the impact of compact fluorescent lamps (CFLs) on electricity reliability and household electricity consumption in the Kyrgyz Republic. Greater saturation of CFLs within a transformer leads to fewer outages, a technological externality benefiting all households, regardless of individual adoption. Spillovers in CFL adoption further reduce electricity consumption, contributing to increased reliability within a transformer. CFLs' impacts on household electricity consumption vary according to the effects on reliability. Receiving CFLs significantly reduces electricity consumption, but increased reliability permits greater consumption of electricity services.
