%X Energy efficiency is correlated with many factors of influence: Gross National Income per capita, energy imports (% of energy use), renewable combustible and waste (% of total), energy use per capita, services as % of GDP and others. In this paper we are testing a model of piecewise linear regression with breakpoint in order to measure the influence of these factors on the variation of GDP per unit of energy use in Europe in the year 2003.
