The landscape of renewable energy finance has evolved rapidly. Since 2012, renewable power capacity installations have exceeded non-renewables by a rising margin, representing about 60% of all new power-generating capacity added worldwide in 2016 (IRENA, 2017a). Investment reached a comparable milestone in 2015, when renewable power technologies for the first time attracted more finance than non-renewable power technologies (Buchner et al., 2017), a trend that has continued subsequently.
