Home energy consumption
Over the past few years there has been an increase in the demand for improvement of comfort conditions in homes, both in terms of thermal comfort (through the installation of air conditioning equipment) and in terms of the purchase of equipment that facilitates daily tasks.
These behaviors result in an increase in energy consumption that, inevitably, is reflected in the bill of consumers.
Energy consumption in the domestic sector
According to the Survey on Energy Consumption in the Domestic Sector 2010 (ICESD 2010), the residential sector had, in 2010, about 3.9 million homes, verifying that this universe was responsible for 17.7% of the annual final energy consumption (value greater than 99 GWh in electricity and natural gas).
In recent years, energy consumption in the domestic sector has been changing, with electricity rising to the first place in the ranking of the most sought-after energy source in the housing sector (99.9% of homes) and natural gas to the 4th position, with a progressive increase since 2006 (21.1% of households).
Considering the universe of existing homes, it is verified that the estimated consumption of electricity is 14 442 GWh and natural gas 3 064 GWh, corresponding to a global expenditure of more than 2,193 billion euros (about 2,000 billion in electricity and 193 million euros in natural gas) for Portuguese families.

Energy consumption in homes
In a home, the consumption of electricity and natural gas is higher in the winter months, due to the use of space heating equipment, although this equipment does not, as a general rule, exceed the usage period of 5 months per year (it is estimated 3 months during winter and 2 months during summer).
Household equipment is thus typified, taking into account its specific purpose: air conditioning, hot water (DHW), kitchen, equipment (computers, television, computers, among others) and lighting.

Average consumption in a habituation
Regardless of having air conditioning in your home, the majority of electricity consumption is related to kitchen equipment, whereas natural gas varies between the kitchen and the production of hot water. Keep these values in mind when considering replacing your equipment. Remember that replacing an old lamp with an LED lamp can represent significant savings, however it will always be the kitchen equipment that will represent the largest share of your energy bill, so if you want significant reductions in your energy bill, you will have to act on this equipment and opt for more efficient models.
