The color codes on the maps represent the number of studies found for each country or territory.

IRENA initiated a global collection of existing materials on renewable energy potentials. This led to more than 10, 000 references being collated from those available over the internet. The references broadly cover different types of information, from GIS-based systems, to grey literature providing some information on a country. The geographic scale of the different references also varies widely, from global analyses to continent, country or regions.

The definition of renewable energy potentials was considered in its broader sense. In reality, most of the studies provide an indication of a renewable energy resource - the incoming energy, and a very few studies indicate the potential – the energy usable for human applications. The choice of definition was deliberate allowing for the collection of available information even from those topics that are rarely studied, and where any indication of a potential resource has value in initiating further investigations.

The color codes attached to the individual countries represent the number of studies found. This value can, in some cases, provide an index of the level of interest for a certain technology in a given country.

The system developed by IRENA only provides links to the information. It is not intended to duplicate the vast amount of available knowledge on IRENA’s servers. This approach enables the project to maintain a relatively light infrastructure, to add missing information dynamically, and to avoid issues with intellectual property rights. Conversely, this means the database is sensitive to changes in internet links.
