The Abatement of Gaseous Emissions by Energy Efficient Lighting

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).
