*"* ... *geothermal development has a very unique characteristic, since it includes the upstream phase, similar to that of oil and gas sector".* (PS)

He further underlined the transferability of management know-how from the fossil fuel economy to the geothermal business. In essence, the pitfalls of Indonesia's oil and gas industry retrospectively provide lessons learnt for the management of geothermal. Although these two sectors quite different in terms of the nature of the commodities involved, PS believes that the technical management know-how from the oil and gas industry should be transferred and refined.

There is a difference between the outcome of the renewable energy selection provided by several authors in their previous works and the renewable energy selection as a result of the discussion between the stakeholders. For example, Tasri and Susilawati (2014) [10] evaluated that hydropower is more suitable than geothermal energy. On the other hand, earlier research on renewable energy, Rumbayan and Nagasaka (2012) [9], evaluated that geothermal, solar, and wind energy are the most suitable renewable energy. In this research, having considered many factors from the stakeholders' point of views, such as its availability; technology; and operational, financial, and market situation, geothermal energy is the most suitable renewable energy in Indonesia. Therefore, future research focusing on the geothermal energy development would certainly enhance the renewable energy development Indonesia. However, since the stakeholders contended that the lagging development of geothermal energy sources is mainly caused by the hefty initial cost, government intervention is needed, e.g., in the form of financing schemes.

**Finding 3:** Geothermal stood out during the FGD as the most promising renewable energy source that Indonesia should develop.

**Finding 4:** Exploration of geothermal utilisation needs an intervention from the government in the form of financing schemes, so as to alleviate the burden of upfront investment.
