The growth in capacity addition of renewable energy sources has stalled, says a report by the International Energy Agency (IEA). According to the report, the year 2018 was the first year since 2001 in which the growth in renewable power capacity could not increase on a year-over-year basis. New net capacity from solar PV, wind, hydro, bioenergy, and other renewable power sources increased by about 180 GW in 2018, the same as the previous year.
