Last month we have asked you to send us your abstracts about your #lovegeothermal for our essay competition. And now we are happy to announce the winner!

The best story was from Indonesia, written by Yose Ardhani Farasi! Our sincere congratulations!

We would also like to thank other participants for their time and commitment to geothermal.

Greetings from the IGA Team.

#lovegeothermal from Indonesia
Yose Ardhani Farasi

Geothermal is an energy with almost free carbon dioxide and other emissions. Approximately 1000 MW geothermal power plant could save 20 million tonnes of CO2 each year. Indonesia is one of the largest geothermal energy producer. In 2018, Indonesia has overtaken the Philippines as the second largest geothermal power producer in the world with an installed capacity of 1,800 MW. Approximately 40% of the world’s geothermal energy reserves are located beneath the earth surface of Indonesia. This energy has a high potential to be a source of renewable energy. But apparently, geothermal energy utilization in Indonesia is still limited.

In order to assist my country in geothermal journey, I am very active in geothermal sphere. I got the first appreciation award for writing competition hosted by International Indonesia Geothermal Convention & Exhibition 2013. I have work experience in geothermal power production since my undergraduate final assignment at Star Energy Geothermal (Wayang Windu) Limited in 2016. My undergraduate thesis was about, “Thermodynamics Analysis of Kalina Cycle System (KCS) 11 for Jailolo Geothermal Field – Halmahera”.

To be one of the Indonesian geothermal experts, I hope that my interest, passion, & ability may contribute to the energy development in Indonesia.

The international geothermal community mourns the loss of Ruggero Bertani, who recently lost his life after a battle with cancer.

Mr. Ruggero Bertani held a Degree in Physics from Pisa University. From 1979 to 1982 he worked for different Nuclear Physics Laboratories in Italy (INFN, Roma and Pisa) and abroad (CERN, Geneva and Fermilab, Chicago). In 1982 Mr Ruggero Bertani started working for ENEL and was Project Director in the Innovation Department at Enel Green Power and Manager on Geothermal Business Development at Enel’s International division in Italy since 1982.

At ENEL Mr. Ruggero Bertani was responsible for development projects in Berlin and Ahuachapán (El Salvador) and for reservoir assessment in Italy and geothermal fields acquisitions in USA.

During his career Mr. Ruggero Bertani actively participated in a range of different international activities. For example as member of the Consulting Panel of Expert for Geothermal Energy in the 6th Framework Programme, Executive Director and Board member of IGA (International Geothermal Asssociation), President and Board member of the EGEC (European Geothermal Energy Council), Coordinator for the DESCRAMBLE H2020 project, and Chairman of the European Technological and Innovation Platform (ETIP) on Deep Geothermal.

He was the main author of the geothermal chapter of the IPPC report 2009 and leading author of the geothermal chapter in the Special Report on the Renewable Energy Sources (SRREN) of IPCC working group, and published an important book in 2017 on “Perspectives for Geothermal Energy in Europe”. He also was the author of the Global Updates for the Geothermal Power Sector for the World Geothermal Congress of the International Geothermal Association (IGA) since 1995.

Mr. Ruggero Bertani participated in the International Panel of the IEA for the elaboration of the geothermal roadmap. Furthermore Mr. Ruggero Bertani was author or co-author of more than 60 papers, published in International Journals as well as in official publications of International Bodies.

“With Ruggero Bertani, the international geothermal energy community has lost one of its most influential individuals. His dedication to geothermal energy and its promotion through his work at IGA, first as Executive Director, then Board Member and Vice President, and as of late as President of EGEC, has been remarkable and incredibly important for us as an industry. We are eternally grateful for his contribution and extend our condolences to his family and colleagues at Enel in Italy.”, Alexander Richter, President of the International Geothermal Association.

In the words of Miklos Antics, EGEC vice-President: “He was a unique asset to the geothermal community and we will cherish his memory forever.” And of Javier Urchueguia, EGEC vice-president:  “He always was a warm and excellent person.”

To continue the tradition, we encourage you to send us your geothermal pictures for the IGA Photo Contest 2018 to

As usual, the winners will get nice gifts. Good luck!

Preparing for the future – The International Geothermal Association is implementing far reaching changes

Upon concluding a tremendous amount of work on a strategic alignment program, the International Geothermal Association is implementing a series of changes. These improvements will help prepare the geothermal sector for the future and emphasize the IGA’s role in the representation of the Global Geothermal Energy Sector.

To focus and strengthen its role, the International Geothermal Association (IGA) is proud to announce a series of reforms following the recent decisions made during the IGA Board of Directors meeting in Reykjavik, Iceland.

IGA has made strides toward a more sustainable, independent structure that reflects the international nature of the representing body of the global geothermal sector through the association. This effort will transition IGA to an independent structure and position itself for growth by changing its funding model and modus operandi.

IGA understands the need to sharpen its value proposition for members and has taken steps to redefine elements of its membership model. Henceforth, IGA will increase its emphasis on the industry with different corporate membership levels and engagement. At the same time, the association will sharpen its profile towards value proposition for our affiliated members, national associations, and institutions.

“With these changes, we are strengthening our position and engagement with international partners in our work highlighting what geothermal energy has to offer in the global energy transition. With the adaptation of our operational model we strengthen the role we play for our members and the wider global geothermal energy community.” – Alexander Richter, President of IGA & Principal, ThinkGeoEnergy

Alongside many ongoing and planned initiatives, the IGA is striving to create value for the geothermal sector and expand its collective voice on behalf of global geothermal development. These initiatives are already well underway with the deployment of UNFC Specifications for Geothermal Energy Resources, and engagement on the Geothermal Sustainability Assessment Protocol. IGA is planning to establish an Advisory Council to support IGA and its initiatives.

“Working on initiatives like the UNFC Specifications for Geothermal Resources and efforts on a Global Geothermal Sustainability Assessment Protocol, are aimed at supporting an accelerated deployment of geothermal energy, strengthening the global geothermal energy industry for further growth and utilizing all that geothermal energy has to offer.” – Bruno Della Vedova, Secretary, IGA & Associate Professor, Fondazione Internazionale Trieste

IGA is actively taking steps for a deeper engagement with industry on activities and alignment that supports and strengthens our scientific and academic roots.

Furthermore, IGA has decided to change the frequency of the World Geothermal Congress from every five to three years. Following the World Geothermal Congress 2020, which will be held from April 27 to May 1, 2020 in Reykjavik, Iceland, the next congress will take place in 2023. The aim of this decision is to engage more frequently with our global members and emphasize the importance of promoting geothermal energy and its benefits for other industries.

“In the recent years the world-wide boom of renewable energy for power production has also seized geothermal. Especially in South-East Asia, Africa and Turkey the growth rates are impressive. Geothermal for heating has developed exponentially in China and some areas in Europe. Therefore, it is time to increase also the frequency of WGC, the most important platform of the geothermal sector for exchange of ideas, information and technology among practitioners, academics, industry and policy makers from the whole globe.” – Peter Meier, Chair of Information Committee, IGA & CEO, Geo-Energie Suisse AG

IGA is preparing a new communications strategy with the goal of increasing engagement with its membership, affiliated organizations, partners and the wider international geothermal community. Today, IGA is also proud to present and launch their new website: and
