To solve the climate crisis, the world must make a wholesale shift to renewable energy technologies. With surging growth in emerging markets, this transformation takes on even greater urgency. The challenges - and opportunities - are immense. Selling Solar considers how such a shift might happen. Focusing on the case of solar photovoltaics, it shows how, at the start of the twenty-first century, this promising technology began to diffuse rapidly in select emerging markets, after years of struggling to take off. This book offers important lessons for the diffusion of a range of renewable energy technologies in emerging markets, and for the advancement of the sector as a whole. Selling Solar is essential reading for anyone who believes in a renewable energy future and wants it sooner rather than later.
