About Us

Launched at COP21*, the Global Geothermal Alliance (GGA) serves as a platform for dialogue, cooperation and coordinated action between the geothermal industry, policy makers and stakeholders worldwide.

As stated in the Joint Communiqué on the Global Geothermal Alliance, the GGA is a coalition for action to increase the use of geothermal energy, both in power generation and direct use of heat. It calls on governments, business and other stakeholders to support the deployment of realizable geothermal potential. The Alliance has an aspirational goal to achieve a five-fold growth in the installed capacity for geothermal power generation and more than two-fold growth in geothermal heating by 2030.

What the GGA is designed to do?

  • foster an enabling environment to attract investments in geothermal energy;
  • provide customised support to regions and countries with geothermal market potential;
  • facilitate the exchange of insights and experience among key stakeholders in the geothermal energy value chain;
  • identify and promote models for sharing and mitigating risks, in order to attract private investment and integrate geothermal facilities into energy markets.
  • help to streamline outreach efforts to give geothermal energy greater visibility in the global energy and climate debates.

* The 21st Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC), held in Paris, France, in December 2015

How To Join?

The GGA is an inclusive and neutral multi-stakeholder platform that brings together public, private, intergovernmental and non-governmental actors that share a common vision of accelerating the deployment of geothermal energy for power generation and other applications.

Member countries include geothermal resource-rich countries with established or emerging geothermal markets, along with other countries that wish to support the activities of the Alliance.

Partner institutions include:

  • Development partners, international and bilateral development organisations, international financial institutions, institutional investors, international organisations, and other development partners involved with geothermal energy.
  • Geothermal industry represented by geothermal business associations at the global, regional and national levels.
  • R&D and academic organisations operate in the geothermal energy field at regional, national or subnational levels.

Requests by interested countries and institutions should be sent to the International Renewable Energy Agency (IRENA), the coordinator and facilitator of the GGA, by way of an official written request addressed to IRENA’s Director-General.

Member countries and partner institutions are not required to contribute any membership fee. The costs associated with GGA activities, including coordination meetings, shall be borne by participants.

GGA Action Plan

The GGA Action Plan was endorsed by Members and Partners in May 2016, based on the principles stipulated in the GGA Joint Communique. It is set to coordinate closely with existing structures, programmes and facilities that share the common objective of promoting geothermal energy deployment at the international, regional and national levels. The Alliance will operate based on activities linked to the priority action areas identified in the GGA Action Plan, and will be supported in implementation as well as funding by committed Members and Partners.

The Global Atlas for Renewable Energy is a free online resource-assessment tool inclusive of maps on geothermal energy as well as solar, wind, marine and bioenergy resources. It facilitates a first screening of areas of geothermal investment opportunity

The BBA Geothermal Transparency Guide is an online tool which provides an insight into the legal frameworks governing exploration and development of geothermal energy, as well as an overview of data on energy production and capacity. Currently, 16 countries endowed with geothermal resources are featured in the database, with further countries to be included.

Regional and International Training Centres

IGA database of global geothermal courses is an online platform that provides an overview of geothermal training courses and programmes by continent and country.

The information presented includes the location and name of the course or programme, the teaching language, the main research focus, the qualification awarded and contact details. 

The Geothermal Training Programme in Iceland (GRO GTP) is a postgraduate training programme to assist developing countries build capacity for geothermal exploration and development.

The programme consists of six-months’ training for practising professionals from developing and transitional countries with significant geothermal potential. Priority is given to countries where geothermal development is under way, to maximise technology transfer. The programme is offered annually and covers eight specialised themes:

  • geothermal geology
  • geophysical exploration
  • reservoir engineering and borehole geophysics
  • chemistry of thermal fluids
  • environmental science
  • geothermal utilisation
  • drilling technology
  • project management and finances

The Geothermal Training programme operated in Iceland between 1978 and 2019 as the United Nations Geothermal Training Programme (UNU-GTP) as a collaboration between the Government of Iceland and the United Nations University; and from 2020 it operates as GRO GTP under the auspices of UNESCO (United Nations Educational, Scientific and Cultural Organization). It is hosted at Orkustofnun (National Energy Authority of Iceland).

The hallmark of GRO GTP is to give university graduates engaged in geothermal work intensive training in their chosen fields of specialisation. The trainees work side by side with geothermal experts in Iceland drawn from Iceland GeoSurvey, University of Iceland, Reykjavik University and other agencies/companies. The aim is to help developing countries with significant geothermal potential build up groups of specialists that cover most aspects of geothermal exploration and development. This increases their capacity to develop and utilise their geothermal resources.

GRO GTP also offers successful candidates the possibility of extending their studies to MSc or PhD degrees in geothermal sciences or engineering in co‑operation with the University of Iceland and Reykjavik University. Short course series are offered annually in East Africa (held in Kenya) and Latin America and the Caribbean (held in El Salvador) in support of the UN Sustainable Development Goals.

High-Level Conference of the Global Geothermal Alliance: Working Together to Promote Geothermal Energy Towards a Sustainable Energy Future11-12 September 2017 in Florence, Italy

The first high-level conference of the Global Geothermal Alliance took place on 11 September 2017 in Florence, Italy. The meeting was attended by 230 high-level public, intergovernmental, non-governmental and senior private sector representatives. Under the terms of the ‘Florence Declaration’ – an outcome of the meeting – governments reaffirmed the commitment to work together to identify and implement measures that will significantly increase the speed of geothermal energy development around the world.

Agenda, presentations, and pictures of the conference are available here

    Powering Agri-food Value Chains with Geothermal Heat

    In the framework of the Global Geothermal Alliance, the International Renewable Energy Agency (IRENA) collaborated with the International Geothermal Association (IGA), the United Nations Food and Agricultural Organisation (FAO), and the United Nations Environment Programme (UNEP) to organise a series of webinars to share global experiences and best practices for accelerating the use of geothermal heat in the agri-food sector. The webinars build on IRENA’s guidebook for policymakers on Powering Agri-food Value Chains with Geothermal Heat and its flagship publication on Renewable Energy for Agri-food Systems.

    Global Webinar: 23 June 2022
    Presentations and recording available here.
