What does it mean?

The concept

 

The EnergizAIR indicators have one thing in common: they are all about the covering of energy needs. For the last seven days, the indicators give you an idea on how much you have been able to cover thanks to renewable energies. The production is translated into two sorts of indicators: a familial one for the solar technologies, a collective one for the wind energy.

 

Solar technologies

 

For both solar thermal and photovoltaic technologies, the indicator is a percentage. Where does it come from ? We compare the energy that has been produced by a standard installation (whose characteristics are different for each country) with the average needs of a standard family (according to the national statistics). The figure gives you the percentage of the needs (either in hot water or in electricity) that an equipped family has been able to cover thanks of the weather of the last seven days.

 

Wind technology

 

For the wind, the indicator gives the amount of households that could have been powered by the production of the wind turbines of the country.

 

How do we get the figures ?

 

The indicators are generated by correlating statistical consumption and population data with the production data of the three technologies.

 

Acquisition of statistical data

 

In each country, the partners of the project have gathered statistical data regarding the average household and the average energy consumption in terms of electricity and hot water, according to the following sources:
