Abstract
The potential for conserving electricity using energy efficient lighting is investigated for the domestic, service and industrial sectors in the UK. A variety of technologies are considered, of which replacement of incandescent lighting and improved ballasting and control of fluorescent installations are the most important. Lighting currently uses approximately 40 TWh/year (8% of UK electricity). It is found that at least half of this could be conserved using technologies which are already cost effective. A variety of market barriers result in these savings not being achieved. If policy measures were adopted to overcome these barriers, emissions would be reduced by 3.3 MteC/year of carbon dioxide (2% of the UK total) and 100 kteS/year of sulphur dioxide (5% of the UK total).
