A first-of-its-kind study into rooftop solar energy identifies 'hot-spots' where investment could have the greatest benefits for climate change. The first detailed global assessment of the electricity generation potential of rooftop solar panels has revealed that the total global potential for electricity produced in this way exceeds all the energy used worldwide in 2018.
Scientists from University College Cork (UCC) in Ireland, Columbia University in the Unites States, Ahmedabad University in India and Imperial College London in the United Kingdom have published their findings in the journal Nature Communications.
The new data has also identified 'hot-spots' in India and China where investment in rooftop solar panels could have the greatest impact on climate change and the environment.
Dr Shivika Mittal, Research Associate in Energy and Integrated Assessment Model at the Grantham Institute - Climate Change and the Environment at Imperial College London, and a co-author of the study, said: "The cost of generating electricity from solar rooftop panels has declined significantly in the last decade. This new data set will help governments or organisations, business owners to identify solar power 'hot-spots' where they can mobilise investment for new solar panels, and this would help in accelerating the adoption of solar power," she continued.
