Can a solar-wind system meet future energy demands?

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.

How has China shaped the global supply and demand of solar PV?

Government policies in China have shaped the global supply, demand and price of solar PV over the last decade. Chinese industrial policies focusing on solar PV as a strategic sector and on growing domestic demand have enabled economies of scale and supported continuous innovation throughout the supply chain.

Who is the world's largest generator of wind and solar?

NextEra Energy (USA) is often cited as the world’s largest generator of wind and solar, through its subsidiary NextEra Energy Resources, with over 30 GW of installed capacity and a huge pipeline.

How many countries does China's wind & photovoltaic products reach?

China's wind and photovoltaic products have reached over 200 countries and regions worldwide -- not only enriching global supply but also making outstanding contributions to green energy transition and the stability of the global energy market, Zhang added.

Are solar and wind resources interconnected?

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”).

What are the top wind turbine OEMs in the world?

Top wind turbine OEMs globally include Vestas (Denmark), Siemens Gamesa Renewable Energy (Europe) – now part of Siemens Energy, GE Renewable Energy (USA), and leading Chinese manufacturers like Goldwind and Envision.
