Abstract

The purpose of this paper is to analyse the correlation between humankind’s energy input measured in terms of primary energy supply and wealth generation measured in terms of gross domestic product (GDP). In contrast to conventional energy statistics we consider energy from biomass, which we estimate by taking a new approach based on society shares, to obtain a comprehensive picture of societal energy supply. Against the background of declining fossil energy resources and restricted natural biomass production, we want to create a more profound view about the known fact that much of humankind’s wealth is actually based on the availability of energy. In this regard we undertake a long-term analysis of energy supply and GDP development, disclosing an increasing impact of biomass on GDP. Our results suggest that humanity has embarked upon a non-sustainable path in terms of wealth creation not only based on fossil carriers, but also on the non-sustainable production of biomass. Keywords: primary energy supply, biomass, economic growth, sustainability.
