Powering the world: can solar energy tackle climate change?

Renewable energy is a strong component in the race to mitigate climate change, and solar power is a particularly cheap and viable green energy option. Considering current technologies, cost, markets and infrastructure, Professor Henry Snaith, Co-Director of the Programme on Solar Energy: Organic Photovoltaics, and Professor Malcolm McCulloch, Head of the University of Oxford’s Electrical Power Group and Co-Director of The Oxford Martin Programme on Integrating Renewable Energy, will debate whether solar is indeed the answer to the urgent question of irreversible climate change.
