We estimate renewable energy (RE) potential in Bangladesh considering land-use conflicts. • We find 53 GW of low-cost utility-scale PV potential, far more than previously estimated. • Though more expensive, rooftop solar PV could provide 17% of current peak demand (2 GW). • Meeting Bangladeshi 2030 RE targets requires only 0.17% of total land area. • Even with a conservative land use program there is enough RE capacity to support growth.

Today resource adequacy is most often maintained by installing natural gas plants to meet the peak load. In California, the current risk of inadequate electricity supply is highest around sunset in late summer. In a zero-carbon grid, resource adequacy will increasingly require adequate stored energy throughout the entire year. Here we seek to develop an intuition about the times of the year when resource adequacy may be most challenged for a solar-dominant system. We use a simplified approach and show that the month of the biggest challenge occurs in winter and can shift by more than two months depending on the amount of solar and storage that are built.

Korean Power System Challenges and OpportunitiesPriorities for Swift and Successful Clean Energy Deployment at Scale With South Korea's electricity demand expected to grow 30% by 2035, transitioning to clean energy resources will be critical in reducing the electric sector emissions and achieving national climate goals.Rapid technological improvements can help keep costs low and maintain grid reliability, if Korea's government takes a coordinated approach to the clean energy transition. This policy brief identifies key barriers to Korea's shift toward clean energy, based on the authors' companion report (A Clean Energy Korea by 2035: Transitioning to 80% Carbon-Free Electricity Generation ), interviews with experts, and the most recent data and literature. It then explores policy solutions for overcoming these technological, economic, and institutional barriers, and suggests market transformation strategies to speed the adoption of clean energy technologies. Amid ongoing cost and technological improvements in wind, solar, and energy storage, advancing this report's recommended policy actions with maximum coordination among government officials can meaningfully accelerate Korea's clean energy transition.

The current global energy crisis has massive implications for the people and economy of South Korea (Korea), where at least 90% of energy use depends on foreign fossil fuels. Clean electricity accounts for only 39% of total generation, with electricity demand expected to increase 30% by 2035. This study shows that Korea can achieve 80% clean electricity by 2035 by capitalizing on rapid technological improvements and decreasing costs of solar, wind, and battery technology. Doing so would slightly lower electricity supply costs, significantly reduce dependence on imported natural gas and coal, and dramatically cut power sector emissions. Further, this study finds that Korea' s power grid under a clean energy scenario will maintain reliability without coal generation or new natural gas plants. To realize these significant economic, environmental, and energy security benefits, policies such as an 80% clean electricity standard by 2035 and corresponding renewable energy deployment goals are required.
