Our latest modelling sets out the important role of renewable energy in the future energy system. Over the longer term, we expect a huge scale up of renewables to decarbonise the power sector and improve energy access. Renewables are also likely to grow in other sectors to provide low-carbon heat and transport solutions.

Access our latest long-term analysis to gain insight into potential future scenarios for renewable energy globally.

World Energy Outlook

Since 1993, IEA's World Energy Outlook (WEO) has provided medium- to long-term energy projections using the World Energy Model (WEM). The model is a large-scale simulation model designed to replicate how energy markets function and is the principal tool used to generate detailed sector-by-sector and region-by region projections for the WEO scenarios. Updated each year, the WEO highlights recent trends in energy and energy policies.

Energy Technology Perspectives Model

The IEA Energy Technology Perspectives (ETP) analysis offers a comprehensive, long-term view of energy system trends and technologies essential to meet goals for affordable, secure and low-carbon energy.
