The presence of incentive measures to encourage the deployment of clean energy is not sufficient in itself to ensure that investment reaches the desired levels. Governments also need to address disincentives, including reforming inefficient fossil-fuel subsidies and pricing carbon dioxide emissions. In addition, governments must address market and regulatory rigidities that favour fossil-fuel incumbency in the electricity sector and can adversely impact the investment attractiveness of clean energy sectors. For instance, they can try to create a level playing field between independent power producers of clean energy vis-a-vis fossil-fuel based power utilities.
