Universal access to modern energy services is achievable by 2030. There are no fundamental technical barriers, and proven and innovative solutions exist. The capital investment required for universal energy access represents only around 3 per cent of the total global energy investment. Governments must make universal energy access a top political priority. Practical, effective and large-scale actions are needed to invest in capacity development, mobilize public-private partnerships and massively scale up successful and innovative solutions to overcome extreme energy poverty.
