The global share of renewable energy can reach as high as 36% by 2030 with technologies that are already available today as well as with improved energy efficiency and energy access. Going further than this will require thinking “outside the box”, with early retirement of conventional energy facilities, technology breakthroughs and consumer-driven societal change. The report summarised here, prepared by the International Renewable Energy Agency (IRENA) through broad consultations and engagement around the world, provides a global roadmap for doubling the share of renewables in the energy mix.
