The decade-long trend of strong growth in the global renewable energy sector continued in 2018, according to the International Renewable Energy Agency (IRENA).
IRENA’s latest data shows that 171 GW of new renewable energy capacity was added globally in 2018, an increase of 7.9 per cent over additions in 2017.
Solar and wind energy accounted for 84 per cent of the growth, and one-third of global power capacity is now based on renewable energy, IRENA says.
While Asia accounted for 61 per cent of total new renewable energy installations and grew installed renewables capacity by 11.4 per cent, growth was fastest in Oceania that witnessed a 17.7 per cent rise in 2018. Africa’s 8.4 per cent growth put it in third place just behind Asia. Nearly two-thirds of all new power generation capacity added in 2018 was from renewables, led by emerging and developing economies.
“Through its compelling business case, renewable energy has established itself as the technology of choice for new power generation capacity,” said IRENA Director-General Adnan Z. Amin. “The strong growth in 2018 continues the remarkable trend of the last five years, which reflects an ongoing shift towards renewable power as the driver of global energy transformation.
“Renewable energy deployment needs to grow even faster, however, to ensure that we can achieve the global climate objectives and Sustainable Development Goals,” continued Mr. Amin. “Countries taking full advantage of their renewables potential will benefit from a host of socioeconomic benefits in addition to decarbonising their economies.”
IRENA’s analysis also compared the growth in generation capacity of renewables versus non-renewable energy, mainly fossil-fuels and nuclear. While non-renewable generation capacity has decreased in Europe, North America and Oceania by about 85 GW since 2010, it has increased in both Asia and the Middle East over the same period. Since 2000, non-renewable generation capacity has expanded by about 115 GW per year (on average), with no discernible trend upwards or downwards.
Globally, total renewable energy generation capacity reached 2351 GW at the end of last year. Hydropower accounts for the largest share with an installed capacity of 1172 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).
