In 2015, global investment in renewables grew about 5 percent relative to the previous year and reached an all-time high of US$ 286 billion (bn). And there are more interesting trends: Investment in renewables’ based electricity generation capacity in 2015 has been more than double the investment in the major fossil fuels (renewables: US$ 266 bn versus US$ 130 bn for coal and gas stations). This also leads to added capacity in terms of Gigawatts in 2015 in renewables (134 GW) outstripping all other technologies combined (conventional coal, gas, and nuclear).

Renewable power has significant potential to reduce the cost of electricity in rural and island settings across the developing world. In areas distant from main power grids, regional isolated grids – often referred to as mini-grids – are often the main source of electricity to industry and households. Power generation usually relies on diesel fuel, often imported over long distances. Yet genera­ting costs can be reduced by hybridising these mini-grids with solar photo­vol­taic (PV) or other renewable power sources.

POWERING AFRICA THROUGH FEED-IN TARIFFS, ADVANCING RENEWABLE ENERGY TO MEET THE CONTINENT'S ELECTRICITY NEEDS

This publication examines the sectors, technologies and policy measures that will be central in the transition to a low-carbon energy system. It addresses the following questions: (1) What are the roles of coal and gas in meeting the stringent decarbonisation requirements for the power sector consistent with IEA modelling of global climate goals? (2) What are moderate carbon prices accomplishing in the electricity sector, and how can they be helpful as part of a package of other policies?

This report provides the results of a review of the evidence that investments in electricity-generating capacity have benefits for poor people, and what factors influence that relationship. The review begins by elucidating a theory to break down the causal chain between additional renewable electricity generation capacity and poverty impacts in four stages or links, which can be formulated as four research questions: (1) What is the link between increased renewable electricity capacity and higher availability and reliability of supply?
