IRENA 2018: Strong Growth in Renewables and Continued Decrease in Hydropower Additions

Hydropower increase in 2018 is less than 21 GW or 17% less than in 2017 and signifies steady decline in this sector for the fifth year in a row. We have no data which part of capacity was added through modernization of old facilities, but expect it to be a sizeable share. China leads in hydropower construction both domestically and overseas. And China Hydropower Association  claimed in January that its members participate in 70% of actively developed  projects around the world. However the hydro as such is less and less relevant to whichever development goals. Renewable capacity expansion continues to be driven mostly by new installations of solar and wind energy. These accounted for 84% of all new capacity installed in 2018, finally pushing the overall share of hydro to just under 50% of non-fossil electricity sources.

But destruction of environment and suppression of local communities caused by greenfield hydropower projects  was still on the rise throughout 2018 from construction of Ilisu Dam on Tigris River in Turkey to forest clearing at the site of BatangToru dam in Indonesia. Accidents happened on many newly completed dams claiming lives of several hundred people and forcing many thousand people to evacuate.

The International Agency on Renewable Energy (IRENA) released  annual Renewable Capacity Statistics 2019, the most comprehensive, up-to-date and accessible figures on renewable energy capacity indicates  growth in all regions of the world. The decade-long trend of strong growth in renewable energy capacity continued in 2018 with global additions of 171 gigawatts (GW), according to new data released by the International Renewable Energy Agency (IRENA) today. The annual increase of 7.9 per cent was bolstered by new additions from solar and wind energy, which accounted for 84 per cent of the growth. A third of global power capacity is now based on renewable energy. 

Hydropower: Growth in hydro continued to slow down in 2018 being below 21 GW, with only China adding a significant amount of new capacity in 2018 (+8.5 GW including 1 GW pumped storage). Also Brazil added 3 GW, Pakistan 2,5 GW, Turkey 1 GW.  Remaining 5 GW widely distributed in small   additions among various countries. Statistics is likely incomplete ( since previously reported 2017 figures were also slightly corrected due to new data submission by countries). All  in all hydropower capacity increase in 2018 is 17% less than in 2017 and signifies steady decline for the fifth year in a row).

  • Wind energy: Global wind energy capacity increased by 49 GW in 2018. China and the USA continued to account for the greatest share of wind energy expansion, with increases of 20 GW and 7 GW respectively. Other countries expanding by more than 1 GW were: Brazil; France; Germany; India; and the UK.
  • Bioenergy: Three countries accounted for over half of the relatively low level of bioenergy capacity expansion in 2018. China increased capacity by 2 GW and India by 700 MW. Capacity also increased in the UK by 900 MW.
  • Solar energy: Solar energy capacity increased by 94 GW last year (+ 24 per cent). Asia continued to dominate global growth with a 64 GW increase (about 70% of the global expansion in 2018). Maintaining the trend from last year, China, India, Japan and Republic of Korea accounted for most of this. Other major increases were in the USA (+8.4 GW), Australia (+3.8 GW) and Germany (+3.6 GW). Other countries with significant expansions in 2018 included: Brazil; Egypt; Pakistan; Mexico, Turkey and the Netherlands.
  • Geothermal energy: Geothermal energy increased by 539 MW in 2018, with most of the expansion taking place in Turkey (+219 MW) and Indonesia (+137 MW), followed by the USA, Mexico and New Zealand.

Globally, total renewable energy generation capacity reached 2,351 GW at the end of last year – around a third of total installed electricity capacity. Hydropower accounts for the largest share with an installed capacity of 1 172 GW – around half of the total. Wind and solar energy account for most of the remainder with capacities of 564 GW and 480 GW respectively. Other renewables included 121 GW of bioenergy, 13 GW of geothermal energy and 500 MW of marine energy (tide, wave and ocean energy).
