Affordable & clean energy

SDG Intro

Goal 7: Affordable & clean energy

Ensure access to affordable, reliable, sustainable and modern energy for all

Ensuring access to affordable, reliable and modern energy for all has come one step closer due to recent progress in electrification, particularly in LDCs, and improvements in industrial energy efficiency. However, national priorities and policy ambitions still need to be strengthened to put the world on track to meet the energy targets for 2030
