Renewables

Renewable energy is at the centre of the transition to a less carbon-intensive and more sustainable energy system. Renewables have grown rapidly in recent years, accompanied by large cost reductions for solar photovoltaics and wind power in particular. The IEA expects renewable electricity generation to increase by a further two-fifths by 2021. However, renewable heat and transport are lagging behind, despite good potential.

The IEA provides in-depth market analysis, policy advice and technology insights to facilitate a rapid scale-up in renewables deployment across the electricity, heat and transport sectors. The IEA works closely with governments, industry partners and the IEA’s Technology Collaboration Programmes. The system integration of variable renewable energy sources is a key focus of our work, with major contributions to global fora such as the Clean Energy Ministerial, the G7 and the G20.
