2 The International Renewable ENERGY Agency (IRENA) is an intergovernmental organisation that supports countries in their transition to a sustainable ENERGY future, and serves as the principal platform for international co-operation, a centre of excellence, and a repository of policy, technology, resource and financial knowledge on renewable ENERGY . IRENA pro- motes the widespread adoption and sustainable use of all forms of renewable ENERGY , including bioenergy, geothermal, hydropower, ocean, solar and wind ENERGY in the pursuit of sustainable development, ENERGY access, ENERGY security and low-carbon economic growth and prosperity.

8 2. F O R E WO R D. Foreword In an era of accelerating change, the imperative to limit climate change and achieve sustainable growth is strengthening the momentum of the GLOBAL ENERGY TRANSFORMATION . The rapid decline in renewable ENERGY costs, improving ENERGY efficiency, widespread electrification, increasingly smart technologies, continual technological breakthroughs and well-informed policy making all drive this shift, bringing a sustainable ENERGY future within reach. While the TRANSFORMATION is gaining momentum, it must happen faster.

9 Around two-thirds of GLOBAL greenhouse gas emissions stem from ENERGY production and use, which are at the core of efforts to combat climate change. To meet climate goals, progress in the power sector needs to accelerate further, while the decarbonisation of transport and heating must pick up steam. As this report makes clear, current and planned policies offer a comparatively slow path, whereby the world would exhaust its ENERGY -related carbon budget in under 20 years, in terms of efforts to keep the GLOBAL temperate rise well below 2 C.

10 The budget for a C limit, meanwhile, would potentially run out in less than a decade. Adnan Z. Amin The ENERGY system, consequently, requires rapid, immediate and sustained change. The Director-General, IRENA. deployment of renewables must increase at least six-fold compared to the levels set out in current plans. The share of electricity in total ENERGY use must double, with substantial electrification of transport and heat. Renewables would then make up two-thirds of ENERGY consumption and 85% of power generation. Together with ENERGY efficiency, this could deliver over 90% of the climate mitigation needed to maintain a 2 C limit.
