The United States leads geothermal capacity globally at 3.6 GW, while the Philippines (1.93 GW) and Indonesia (1.59 GW) are notable players. New Zealand, Italy, and Mexico follow, with capacities close to 1 GW. Turkey, Kenya, Iceland, and Japan round out the top ten. These data points, from 2023, demonstrate the established capacity rankings in geothermal energy. Over the past two years, the sector has experienced moderate to upwards growth with somewhat stable year-on-year variations. Over a five-year span, Compound Annual Growth Rates (CAGR) suggest consistent expansion in certain markets such as Indonesia and Turkey.
Future trends to watch include increased investments in geothermal technology and infrastructure, particularly in developing countries with untapped geothermal potential, such as countries in the Ring of Fire. Enhanced geothermal systems (EGS) and direct use applications could also surge, potentially reshaping the landscape of global energy capacity distribution.
