Considering that in El Salvador there are 957,480 families with a consumption around 100KWH per month, and if the measures made in the house model are applied in all these houses with at least 80%; it could be saved 503,251488 KWH in a year, in addition 357,308 tons of CO2 will be not send to the atmosphere and the families will save in total USD$149,572,633.
