ABSTRACT
Lighting accounts for about 17 percent of total electricity use in Brazil, or 45 terawatt-hours (TWh) per year as of 1996. A wide variety of efficient lighting technologies have been introduced in Brazil in the past decade. Adoption and use of these technologies is rising due to their cost effectiveness, savings potential, rising electricity tariffs, and economic stabilization.
This paper reviews the status, market evolution, and energy savings resulting from adoption of six energy-efficient lighting products:
(1) high-pressure sodium lamps
(2) compact fluorescent lamps
(3) circular fluorescent lamps
(4) T8 fluorescent lamps
(5) electronic ballasts
(6) specular reflectors.
We estimate that these six products are reducing total lighting electricity use in Brazil by about 2.8 TWh (6 percent) as of 1996. The total electricity savings more than doubled since 1992 and is currently rising about 20 percent per year.
