Global Renewable Energy Islands Network (GREIN)
Description/achievement of initiative

The International Renewable Energy Agency (IRENA) formed the Global Renewable Energy Islands Network (GREIN), a platform for islands to pool knowledge and share best practices. As a resource for knowledge dedicated to islands, GREIN unites IRENA and its partners in a single space dedicated to the exchange of practical discussion topics related to renewable energy such as roadmaps for deployment, power grid integration, resource assessment, tourism applications, desalination and waste-to-energy systems.

By showcasing the business case for renewable energy technologies in a wide range of island settings, GREIN aims to spur more and more islands to invest in these technologies and accelerate their deployment.

Implementation methodologies

GREIN will connect all partners through a single streamlined exchange platform. Interested parties, including IRENA Members, are invited to indicate interest in joining the GREIN network by contacting the IRENA Secretariat at grein@irena.org. They are also encouraged to assign focal points and identify areas of interest.

Currently, GREIN's interest clusters include Roadmaps for Deployment, Desalination, Power Grid Integration, Waste-to-Energy Systems, Resource Assessment and Tourism. New clusters will be developed subject to expressions of interest from the GREIN membership.

Arrangements for Capacity-Building and Technology Transfer

The principal vehicle for capacity building and technology transfer will be the GREIN web platform through which knowledge on renewable technology options is freely shared. Information shared will also be applied to efforts by IRENA and partners to build the capacities of islands for proper installation of renewable technologies on island buildings and power grids, for design of policies to promote deployment of renewable technologies on islands, for incubation of entrepreneurs to invest in renewable energy, and for audits of cost-effective energy efficiency and renewable energy options in homes and tourist venues.

Coordination mechanisms/governance structure

IRENA hosts the GREIN web platform and manages the information ensuring timely updates and wide dissemination. Regular reviews of developments will be made in the context of the IRENA's Council and Assembly sessions. GREIN members contribute information to the platform in areas of interest.

GREIN activities are implemented within the knowledge context of the SIDS Lighthouses initiative.
