ABSTRACT
Geothermal renewable energy has grown globally especially in various emerging economies in East Africa, Central America, the Caribbean and the South Pacific. Over 80 countries, adjacent to the Pacific Ring of Fire or East African Rift, have been developing various new geothermal renewable resources which could potentially double the global geothermal power generation capacity. Looking ahead to 2020–2025, experts have estimated that the total geothermal renewable investments could reach some USD9 billion globally. There are considerable challenges for new technology advancements so geothermal renewables could become more cost competitive against fossil energy options. Details of the geothermal renewable developments in various emerging economies globally will be discussed more in this chapter with international examples.
