A globally interconnected solar-wind power system can meet future electricity demand while lowering costs, enhancing resilience, and supporting a stable, sustainable
Accelerating energy transition towards renewables is central to net-zero emissions. However, building a global power system dominated by solar and wind energy presents immense challenges. Here, we demonstrate the potential of a globally interconnected solar-wind system to meet future electricity demands.
Our estimates suggest that the total electricity generation from global interconnectable solar-wind potential could reach a staggering level of [237.33 ± 1.95] × 10³ TWh/year (mean ± standard deviation; the standard deviation is due to climatic fluctuations).
Compressed air energy storage (CAES) effectively reduces wind and solar power curtailment due to randomness. However, inaccurate daily data and improper storage capacity configuration impact CAES development.
When solar-wind generation within a grid exceeds its net power demand (i.e., total demand minus baseload), surplus power is first transferred to interconnected grids experiencing shortages, with the remaining surplus stored until capacity is reached. Any surplus beyond storage capacity is curtailed.
