"The global drive to provide universal access to sustainable and modern energy by 2030 is creating numerous opportunities for energy users and suppliers. However, men and women do not benefit equally from these opportunities. As users, they have different energy needs linked to their different gender roles. Gender blindness in the sector has led to women's needs often being ignored. As suppliers, the energy sector has traditionally been male dominated. Despite stark gender differences in the energy sector, there has been a lack of evidence to inform more equitable policymaking. This issue of the IDS Bulletin aims to fill some of these evidence gaps through five original papers, part of ENERGIA's Gender and Energy Research Programme. The issue pays particular attention to women's involvement in the supply chain as energy entrepreneurs, an emerging area of research in the gender and energy space."
