This study provides an overview of the emerging market electricity leapfrog. It demonstrates that emerging markets will not follow the same path to renewables as the developed markets. The study discusses how the developing countries are about to leapfrog fossil fuels in this decade to generate all the growth in their electricity supply from renewables. It focuses on types of leapfrog, the different groups of emerging markets, how advanced the leapfrog is, the forces driving the leapfrog as well as the various barriers to change.
