Globally interconnected solar-wind system addresses future
Here, we outline an optimized, phased pathway for integrating solar and wind energy into a globally interconnected and fully coordinated power system.
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.
The joint operation of wind, solar, water, and thermal power based on pumped storage power stations is not only a supplement and improvement to traditional energy systems but also a crucial step towards a cleaner, more efficient, and more sustainable energy future.
Its strong regulation capability, combined with the random fluctuations of wind and solar power, forms a complementary system that outputs relatively smooth and stable high-quality power, effectively solving the challenges of wind and solar energy development (Bello et al., 2023).
Theoretically, the potential of solar and wind resources on Earth vastly surpasses human demand 33, 34. In our pursuit of a globally interconnected solar-wind system, we have focused solely on the potentials that are exploitable, accessible, and interconnectable (see “Methods”).
