Domestic energy consumption is the amount of energy that is spent on the different appliances used within housing.[clarification needed] In an average household in a temperate climate,[clarification needed] The average energy in a household a year consists of 20000kW-h (WHERE?)[clarification needed]. These figures are surely dependent on size of housing electricity, location and local weather. Other figures are similarly dependent on unspecified factors. --> the yearly use of household energy can be composed as follows:
Note that for households in the developing world these overview data are incorrect (area heating almost reduced to zero, and less and different consumption of energy).[clarification needed]
Daily domestic energy consumption
Below, fairly accurate[clarification needed] estimates are noted for a general[clarification needed] private home in the temperate climate. In addition, rough non equations are noted about the energy requirements for homes in the (sub)tropical climates. The latter however may not be as accurate as the starting numbers have been derived from a table for the temperate climates.[clarification needed] They however give a rough idea. Finally, it should be noted that the latter equations do not differentiate between subtropical climates and tropical climates; again some differences may be present here as well, translating in an even greater margin of error. However, the numbers are only designed to give a general indication and in this they will likely succeed.[clarification needed]
In temperate climates
As can be seen from the table above, a private home in a temperate climate generally needs around 20,000 kilowatt-hours per year (20000 kW·h/year) to fulfill its energy needs.[clarification needed] people use 10 to the 11 watts of power in the US
In (sub)tropical climates
As can be seen from the table, a private home in a subtropical climate generally needs around 8000 kW·h/a (1 kW) to fulfill in its energy needs.
Domestic electricity consumption
Other than the domestic energy consumption, the domestic electricity consumption is the amount of electricity is used within the home. Space heating apparatus that work on other energy sources (eg gas, wood from gas stoves, gas heaters, wood burners, ...) are thus not included. The electricity consumption needs to be known to be able to calculate the electricity one needs to generate to create an off-the-grid system.
Amount and size of powerplants required
As stated, for practical (off-the-grid microgeneration) use, rather than the domestic energy requirements, the domestic electricity requirements need to be taken.
Amount of solar panels required
