Those gains were spoiled by a resurgence in coal-fired power plants, use of which BNEF said was up by a record 8.5 percent between 2020 and 2021. BNEF cites rapidly rebounding energy demand (which rose 5.6 percent year-on-year in 2021), reduced hydro generation due to droughts, and high natural gas prices in Europe as primary drivers of the coal surge.
