This paper discusses the results of a time-dynamic analysis of the possible effects of government and utility-sponsored energy efficiency programs on lighting energy use in Sweden. Efficient technologies include improved lamps, ballasts, luminaires, controls and system designs. We develop dynamic scenarios of electricity demand and efficiency improvement, based on various types of energy performance standards and utility demand-side management (DSM) investment. The scenarios account for the dynamics of equipment turnover, existing trends in technology, and the distribution of energy efficiency among equipment models on the market. We examine the achievable rate of efficiency improvements, which increases over time as new energy-saving opportunities appear in new and renovated buildings but is limited by the rate of turnover of existing buildings and equipment. Efficiency measures and further constrainted by administrative costs, market penetration limits and the technical and institutional feasibility of the efficiency measures. Many of the technologies are cost-effective and likely to be implemented in time, specially if electricity prices increase. However, neither existing trends in technology nor higher energy prices are sufficient to prevent substantial lighting energy growth in all sectors. Residential lighting energy can be reduced by the use of compact fluorescent lamps (CFLs), but their adoption requires both improved economics and increased consumer awareness. For non-residential lighting, the scenarios show that demand-side management (DSM) programs, based on a utility-sponsored shared-savings approach, could keep energy use constant until 2010 despite 45 percent growthin energy services...Ver documento.
