"Serious doubts" have been raised over the Energy Bill according to a new parliamentary report. Concerns were also voiced last month by the Energy and Climate Change Select Committee of MPs about uncertainties surrounding key parts of the bill. The Lords' report criticises the lack of information on how the proposed contract for difference (CfD) feed-in tariffs will work for low carbon generators. It is worried that the process for awarding subsidies through CfD will be largely up to ministers.
