Energy policy is usually gender-blind. This makes it harder to achieve SDG targets relating to gender equality and sustainable energy access for all. The Gender and Energy Research Programme is helping to build the knowledge that countries need in order to develop and reform their energy sectors in a more gender-sensitive way. Energy interventions affect men and women differently. Both can benefit substantially, but only if their differential needs and differing ability to access energy services are properly understood. Gendered approaches can help empower women and reduce poverty. They can help deliver energy interventions that are effective, efficient and sustainable.
