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 electricity demand (from 7 to 10 by night, peak hours), in the domestic sector, electric energy consumption 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

Daylight Savings is a measure that besides favoring an important energy saving, helps to defer investments that would be necessary to build electric generation plants, and avoids the emission 1.2 million tons of CO2 into the atmosphere, principal gas of the greenhouse effect, which contributes to mitigate global warming.

Results obtained on 2008 allow confirming also that Daylight Savings contributed to diminish the electrical energy consumption in 1,100 millions of kilowatts per hour, equivalent to the total consumption of the States of Campeche or Nayarit; or also the residential consumption of the States of Aguascalientes, Colima and Tlaxcala, al together. On the other hand, 9,350 millions on investments were differed.

It is important to mention that this measure has demonstrated its efficiency on practically all the countries that have adopted it. Mexico joins this effort since 1996. Its coordination is in charge of the Energy Secretariat, while FIDE contributes to its realization with studies, evaluation y broadcasting.
