The main objective of the daylight savings is to favor the rational use of solar light during the months of greater incidence of sun rays; since by having one more hour of natural light, in the hours of greater demand of electricity (from 7 to 10 by night, peak hours), in the domestic sector, consumption of electric energy for illumination is reduced.

Application of the daylight savings program, for the electric sector represents a displacement of peak hours or maximum demand of electricity, together with its reduction which allows deferment of investments that year after year are made in the country to fulfill electric energy requirements.

Daylight savings is a measure that has shown its efficiency in practically all countries that have adopted it, Mexico has joined this measure since 1996.

Consumption

12,264 GWh saved during eleven years, are equivalent to the yearly domestic consumption of the states of Jalisco, Mexico, Nuevo Leon, Puebla. Veracruz and the Federal District.

1,131 GWh on 2006, are equivalent to the total domestic consumption of the states of South Baja California, Durango and Tabasco.

Reduction in electric energy consumption that has accumulated during the first eleven years of application of daylight (1996  2006) is equivalent to the electricity consumed by the 25.5 million homes in the country for over fourteen weeks; they are also equivalent to the electricity that would be consumed by 23.4 million 60 Watt bulbs permanently lit during a year.

If these bulbs were put one after the other, they would form a line 1,408 kilometers long.

This program is coordinated by the Energy Secretariat, and FIDE supports its carrying out with studies, evaluation and spreading.
