‌The IEA enables innovation through a wide range of international Energy Technology Initiatives, or ETIs1. Through the ETIs, more than 6,000 experts from over 50 countries work together to accelerate advances in energy technologies. Currently, the IEA supports activity of ten Implementing Agreements dealing with renewable energy technologies.

Energy technology initiatives


The vision of the Implementing Agreement for a Programme of Research, Development and Demonstration on Bioenergy (Bioenergy IA) is to make a substantial contribution to future global energy demand by accelerating the production and use of environmentally sound, socially acceptable and cost-competitive bioenergy. Activities include exchanging information on recent developments through studies and workshops; working with industry to develop handbooks and models; providing information for policy-makers and decision-makers; and compiling guidelines and standards on the use of bioenergy.  There are currently 23 Contracting Parties, including Brazil, Croatia and South Africa.

Ocean Energy Systems:

The aims of the Implementing Agreement for a Co-operative Programme on Ocean Energy Systems (OES IA) are to accelerate the viability, uptake and acceptance of ocean energy systems in an environmentally acceptable way. This includes unbiased, quality analysis of technologies to generate electricity from ocean movements (waves, swells, tides, currents), temperature differences or salt concentrations; as well as technologies related to desalination. There are currently 21 Contracting Parties, including China, Mexico, Nigeria, South Africa and Monaco.

Renewable Energy Technology Deployment:

The goals of the Implementing Agreement for Renewable Energy Technology Deployment (RETD IA) are to identify the main barriers to deployment and provide advice and best practice guidance to policy makers and the private sector. This includes identifying barriers to deployment and providing best-practice solutions to remove them; offering guidance to the private sector and policy makers on innovative business strategies and projects, for example by fostering public-private partnerships; and facilitating ongoing international dialogue and public awareness of renewable energy deployment through concrete examples of deployment solutions. There are currently nine Contracting Parties.
