摘要: Summary Construction of carbon-intensive energy infrastructure is well underway under the Belt & Road Initiative (BRI), challenging global climate target. Regionally abundant solar power could provide an alternative for electricity generation. An integrative spatial model was developed to evaluate technical potential photovoltaic power. The influence impacting factors quantified systematically on hourly basis. Results suggest that BRI region reaches 448.9 PWh annually, 41.3 times regional demand in 2016. Tapping 3.7% through deploying 7.8 TW capacity satisfy projected 2030, requiring investment approximately 11.2 trillion 2017 USD and a commitment land area 88,426 km2, 0.9% China’s total. Countries endowed with 70.7% overall consume only 30.1% electricity. imbalance underscores advantage cooperation investments interconnected grids.
