May 8 (Renewables Now) - Global renewable net capacity additions reached a plateau in 2018 after failing to register a year-on-year increase for this first time since the beginning of the millennium, the International Energy Agency (IEA) said this week.
Both in 2017 and 2018, new capacity additions amounted to 177 GW. According to the IEA’s Sustainable Development Scenario (SDS), the world should be installing over 300 GW annually on average in the 2018-2030 period, if it intends to reach the goals of the Paris Agreement.
The organisation pointed the finger at governmental policies for this “unexpected flattening of growth trends”, since, due to declining costs, renewables are now competitive on their own without needing to resort to subsidies.
“These 2018 data are deeply worrying, but smart and determined policies can get renewable capacity additions back on an upward trend,” the IEA’s executive director Dr Fatih Birol said.
Data on the renewable net capacity additions (in GW) by country and region in 2015-2018 are presented below:
The IEA also warned that the carbon dioxide (CO2) emissions produced by the energy sector increased by 1.7% to 33 gigatonnes, despite a 7% growth in the electricity production from renewables.
