摘要
In October 2023,the International Energy Agency(IEA)released a report identifying inadequate grid infrastructure as a key threat to meeting the climate goals laid out by the Paris Agreement[1],the landmark 2015 international treaty in which 196 parties agreed to limit global warming to well below 2℃ above preindustrial levels[2].Importantly,funding for the treaty’s calledfor transition from fossil fuels to clean energy has accelerated[3],with recently legislated massive governmental subsidies and other incentives(e.g.,the Inflation Reduction Act[4])aimed specifically at promoting renewable energy.However,a commensurate surge in investment in electrical grids has not materialized;instead,it has stagnated for the past decade at around 300 billion USD per year worldwide[1].
