A book, called “Geothermal Energy and Society” has been published in August by Springer. The editors are:

  • Adele Manzella (Italian National Research Council (CNR), Institute of Geosciences and Earth Resources (CNR-IGG), Pisa, Italy)
  • Agnes Allansdottir (Fondazione Toscana Life Sciences, Siena, Italy)
  • Anna Pellizzone (Italian National Research Council, Institute of Geosciences and Earth Resources (CNR-IGG), Pisa, Italy)

This book explores the diverse aspects of the relationship between the technological harnessing of geothermal resources and the societies and local communities in which these developments take place.

The responsible use of geothermal energy can help with mitigating the effects of climate change and contribute to the development of renewable and sustainable energy mix in the transition toward a low carbon society.

As with all other developments in the energy sector, a sustained societal dialogue is  essential as society plays an active role in either accelerating or preventing the development of new energy technologies.

This volume introduces a theoretical framework for a social scientific approach to the field and represents the first tentative collection of empirical case studies on geothermal energy and society from across the globe. It is organized into two sections. The first section is introductory to the issue of geothermal energy and the related policy and societal aspects, and is followed by a selection of eleven case studies constituting the second section. A conclusive chapter brings together the various contributions and sets out the lessons learned for this sector.

On January 1, 2018 de Colombian Geothermal Asocciation AGEOCOL (Asociación Geotérmica Colombiana) was formalised under the Bogota Chamber of Commerce and started working officially. Several initiatives to gather people interested in geothermal energy in Colombia started in the last 5 years. While the efforts of isolated people were not that effective, a group of like-minded people, passionate for geothermal, gave it a kick start in 2017.

AGEOCOL’s main purpose is to facilitate the interaction among communities, government, industry and academia, for the promotion of research, development and use of geothermal resources in Colombia with social and environmental responsibility, under the values of leadership, unity and solidarity. AGEOCOL is supporting already existing groups and activities related to geothermal energy in Colombia and will look for opportunities for them to thrive and be known in the region and internationally. This includes the annual geothermal gathering RENAG (Reunión Anual de Geotermia), the GRC student chapters, and regional technical meetings.

The Association has a membership base of over a hundred people including profesionales, students and  people interested in developing and undertaking geothermal projects. It became a member of the IGA in 2017. AGEOCOL BoD is composed of Pablo Aguilera as the President, Valeria García as Vice-President, Angela Prieto as the Secretary and Carolina Coronado as the Treasurer.

“It is with great sadness that IGA informs the geothermal community on the passing of Noel D. Salonga, a member of IGA’s Board of Directors.

The International Geothermal Association and in particular the board members who have worked with him remember his kindness and passion for geothermal energy. With a keen interest in mentoring and coaching young geothermalists, he has played an important role for the younger generation of geothermalists in his home country the Philippines.

Mr. Salonga has had a 30+ years professional career in the geothermal sector in the Philippines with the Department of Energy (DOE), Philippine National Oil Company-Energy Development Corporation (PNOC-EDC), and  Energy Development Corp. (EDC), last as Assistant Vice President with a focus on research, development and innovation.

He has been member of the Board of Directors of the National Geothermal Association of the Philippines (NGAP) for many years and its immediate past President.

We extend our condolences to his family, loved ones, friends, colleagues at EDC, the National Geothermal Association of the Philippines and his peers in the Philippines geothermal sector.”

Dear geothermal lovers,

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 photos@lovegeothermal.org.

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