DBERR has recently published a Call For Evidence in which it massages figures from John Willoughby to claim that it costs £22,000 to retro-fitt the average house with external insulation but only £3000 per house to provide "decarbonized electricity" from nuclear power stations....

BERR Heat Call for Evidence
WRITTEN BY SARAH MCLEAN

In short, this written response by ACE to the BERR Heat Call for Evidence finds that this Call is very seriously flawed, as it focuses solely on the supply of heat to be used in buildings and does not consider managing heat demand through energy efficiency measures. Even more worrying, the only consideration of energy efficiency is a seriously misleading statement which presents measures in housing as more expensive and the carbon savings from them more difficult to achieve than from increased provision of electricity from nuclear power stations. This attempt by Government to deliberately restrict the consultation to cast nuclear in a more favourable light must be challenged by all who want carbon savings in buildings to be achieved in the quickest possible timetable. ACE believes that the Government should withdraw this document and revise it substantially to take account of a systematic programme of energy efficiency measures.
