The evidence from 2018 clearly indicates that renewable power is here to stay. Solar photovoltaics (PV) and wind are now mainstream options in the power sector, with an increasing number of countries generating more than 20% of their electricity with solar PV and wind. This is good news. But current trends show that bolder policy decisions are needed across all sectors of energy end-use to make our energy systems sustainable.
Geothermal energy is harnessed for the generation of electricity and for various thermal applications, including space heating and industrial heat input. Total geothermal energy output in 2018 was estimated at 630 PJi, with around half of this in the form of electricity (89.3 TWh). Estimates of thermal energy consumption (also known as “direct use”) are more uncertain than those for electricity, due to data collection challenges. Some geothermal plants produce both electricity and heat for various thermal applications.
An estimated 0.5 GW of new geothermal power generating capacity came online in 2018, bringing the global total to around 13.3 GW. Turkey and Indonesia remained the leaders for new installations and accounted for about two-thirds of the new capacity installed.3 Other countries that added capacity in 2018 (ordered by scale) were the United States, Iceland, New Zealand, Croatia, the Philippines and Kenya.
