The International Renewable Energy Agency (IRENA) has released a report to the G20 Energy Transitions Working Group (ETWG) on solutions to integrate high shares of variable renewable energy. The report suggests that the integration of variable renewable energy sources, such as wind and solar, into the power grid requires significant investment in energy storage and flexible generation capacity. The report also highlights the importance of policy support, including the establishment of supportive regulatory frameworks and the development of incentives for renewable energy deployment. The report concludes that the integration of variable renewable energy sources is achievable with the right policies and investments, and can contribute to a sustainable energy future.
