Potential gains of long-distance trade in electricity
研究通过模型和实证分析，发现跨半球和全球电力贸易能利用季节和昼夜互补性，大幅降低能源成本，对政策制定和监管有重要启示。
Electrification of all economic sectors and solar photovoltaics (PV) becoming the lowest-cost electricity generation technology in ever more regions give rise to new potential gains of trade. We develop a stylized analytical model to minimize unit energy cost in autarky, open it to different trade configurations, and evaluate it empirically. We identify large potential gains from interhemispheric and global electricity trade by combining complementary seasonal and diurnal cycles. The corresponding high willingness to pay for large-scale transmission suggests far-reaching political economy and regulatory implications.
