To ask the Secretary of State for Energy what steps he has taken to encourage Government Departments and other public authorities to install low-energy light bulbs in their buildings.

As part of the Government's initiative to improve energy efficiency on the Government estate my energy efficiency office gives advice, and encourages Departments to take all cost-effective energy efficiency measures available. In my Department's Palace street building low-energy light bulbs have been fitted, and other Departments have taken similar measures.
