A new study from the UK highlights that coal pollution significantly hampers solar power generation. Aerosols from coal burning are responsible for over 75 terawatt-hours of lost solar output annually, equating to the energy produced by 84 coal plants. This underscores the broader environmental and energy production challenges posed by coal usage.
- 01Coal is the most polluting fuel, producing high levels of carbon emissions and toxic metals.
- 02In 2023, over 25% of potential solar power production was lost, primarily due to clouds and aerosols.
- 03Aerosols contributed to a loss of 6% in solar power output, translating to over 500 terawatt-hours annually.
- 04The study utilized AI-analyzed satellite imagery to assess solar facility sizes and potential output.
- 05Despite increased solar capacity, 75 terawatt-hours of potential output were lost to aerosols in the past five years.

A recent study conducted by researchers in the UK reveals that coal pollution severely impacts solar power production, primarily through the release of aerosols. These aerosols, along with natural cloud cover, resulted in a loss of over 500 terawatt-hours of solar energy in 2023, which is equivalent to the output of 84 coal plants operating at 1 GW capacity. The research utilized a comprehensive global inventory of solar facilities, enhanced by AI-analyzed satellite imagery and crowdsourced data, to estimate potential solar output. Findings indicate that over 25% of the potential solar energy was lost, with 20% attributed to cloud cover and 6% to aerosols. Notably, while solar capacity has increased, the study highlights that 75 terawatt-hours of potential solar output were lost to aerosols in the five years leading up to 2023. This underscores the critical need to address coal-derived pollution not only for health benefits but also to enhance the efficiency of renewable energy sources like solar power.
