Dear Geothermal Community,

we are happy to announce that the majority of our membership has voted positively on the extension of the current board term for six months. We would like to thank each one of you who casted the vote and found the time to participate in this important decision.

The new board will be elected in 2019 to take seat at WGC2020 so to align with the upcoming World Geothermal Congress. As usual, we are getting ready for the elections and looking forward to meet new, dynamic, proactive, diverse and inspiring people that will drive IGA with energy and zest.

So, get yourself nominated!

With best wishes,
Marit Brommer
Executive Director

The IGA invites its membership to cast their vote on extending the current Board Term by a period of 6 months to April 2020 so as to coincide with the World Geothermal Congress 2020 where the new Board will begin their term at the AGM held at that time. The following addendum will be appended to the Bylaws.

ADDENDUM – Notwithstanding Article 8.g, the Board may, by written resolution passed by a majority of the total number of Directors at that time, extend the term of the current Directors (for the avoidance of doubt, that is from 31 October 2016 to 31 October 2019) by a period of six months to April 2020 so as to coincide with the World Geothermal Congress 2020 where the new Board will begin their term at the AGM held at that time.

“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.”

President IGA

The IGA Photo Contest has come to an end and we have winners!

Breaking the tradition, this year we have decided to make beautiful IGA Magnets instead of the Calendar. We will share them with you very soon! #lovegeothermal

As for now, enjoy the #Sauron Eye by Fabio Sartori.

For three decades IGA has been serving the geothermal community, uniting the geothermal professionals and young scientists from around the world. We connect industry and research and promote geothermal on all possible levels.

We would like to take this opportunity and thank each and every geothermalist for their loyal support, dedicated work and their belief that we can transform the world into the renewable paradise with the power of geothermal.

For this wonderful event we have prepared a game for you: a crossword puzzle! Find out how good you know IGA and Geothermal. Have fun and good luck!

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.
