Switch to energy efficient compact fluorescent light bulbs (CFLs). Incandescent bulbs in the UK are responsible for 6.4 million tonnes of CO2 emissions. Replacing them all with CFL's would cut energy consumption by 80%, which equates to a CO2 saving of 5 million tonnes.

The average household can reduce its electricity bills by £50 by switching all incandescent light bulbs to CFLs. Source: Greenpeace, September 27 2007
