The 2024 Renewable Power Statistics revealed by IRENA spotlight the small development of geothermal electrical energy era and potential within the heating market.
The expansion of the worldwide geothermal energy sector continues to lag behind different renewable energies, however there’s nonetheless loads of untapped potential for geothermal to contribute to the industrial warmth market. That is a number of the many insights from the Renewable Power Statistics 2024 report revealed by the Worldwide Renewable Power Company.
The total report gives datasets on energy era capability for 2014-2023, precise energy era for 2014-2022, and renewable vitality steadiness for over 150 nations and areas for 2021-2022.
Photo voltaic and wind proceed to drive renewable electrical energy development
The full electrical energy era in 2022 is 29,031 TWh, representing 2.4% annual development since 2011. Renewable vitality sources accounted for 29.1% of worldwide electrical energy era in 2022, with the steadiness provided by fossil fuels, nuclear vitality, pumped storage, and different non-renewables. From 2021 to 2022, renewable electrical energy by 7.2%.
From 2010 to 2022, the expansion of renewable electrical energy was largely pushed by photo voltaic and wind vitality. The 2 sources, labeled as variable renewables, contributed 11.7% of the worldwide electrical energy combine in 2022 and develop by 18.2% from 2021. Wind and photo voltaic contributed 2098 TWh and 1294 TWh of electrical energy era in 2022, respectively.
In distinction, the electrical energy era from geothermal assets is at a comparatively low determine of 97 TWh. This represents 2.3% development from the earlier yr and a median annual enhance fee of two.5% since 2014. Asia (30227 GWh) continues to play a significant function in geothermal electrical energy era primarily by the contributions of Indonesia (16677 GWh) and the Philippines (10425 GWh). Different main contributors on the nation stage are the US (19142 GWh), Turkiye (11119 GWh), New Zealand (8544 GWh), Kenya (5325 GWh), Iceland (5916 GWh), Italy (5837 GWh), and Mexico (4536 GWh).
Warmth era
In comparison with electrical energy era, the marketplace for industrial warmth era usually lags when it comes to renewable vitality penetration. In 2022, solely 6.3% of the worldwide warmth era got here from renewable sources, at 936 PJ. The remaining 93.7% was generated from fossil fuels, with a small contribution from nuclear and different non-renewables.
Throughout the renewable warmth era sector, bioenergy remains to be the dominant vitality supply with 91.6% contribution in 2022. Europe contributes greater than 92% of the worldwide renewable warmth era. Asia generated an enormous quantity of warmth (6351 PJ) in 2022, however lower than 1% of this era got here from renewable sources.
Geothermal is described as an “different important supply” of renewable warmth era together with photo voltaic thermal vitality. Nevertheless, industrial warmth is taken into account a extremely viable marketplace for geothermal improvement as it could possibly exploit comparatively lower-temperature assets which might be usually extra accessible. Efforts are ongoing on this entrance, such the GeoHeat initiative in New Zealand and the varied geothermal heating schemes in Europe and North America.
In the direction of tripling the capability of renewables
The 473 GW of renewable capability added in 2023 is the most important annual development since 2000. Nevertheless, the 14% enhance remains to be thought-about inadequate to satisfy the purpose of tripling renewable capability by 2030. Sustaining this development would yield solely 9.7 TW of renewables by 2030, falling wanting the 11 TW purpose.
IRENA had beforehand declared a development fee of 16.1% per yr from 2022 to 2030 can be wanted to achieve the triple up targets. With 2023 having already fallen wanting the goal, renewable vitality capability should now develop past the minimal 16.1% per yr for the remaining 7 years.
