Researchers estimate a cost for universal access to energy

Universal access to modern energy could be achieved with an estimated investment of $65-86 billion per year up until 2030. The proposed investments equate to just 3-4% of current global energy system investments. Improved access to clean-cooking fuels and stoves could avert between 0.6 and 1.8 million premature deaths in 2030.
