• Annual changes in the relation between EROIsoc, GDP, EC, and QoL are investigated.
• The relation between EROIsoc, GDP, EC, and QoL differs between OECD and non-OECD.
• The importance of EROIsoc for OECD increases in times of increasing energy prices.
• The importance of GDP for non-OECD decreases in times of increasing energy prices.
Abstract (from article):
Since the efficiency of obtaining energy is decreasing, it is important to determine how the degradation
in energy quality will influence society. Despite the rising importance of net energy, few quantitative
studies have been conducted on the relationship between energy quality and quality of life (QoL).
Energy return on investment on a society scale at a national level (EROIsoc) is used as an indicator of
energy quality, energy consumption (EC) per capita is used to represent energy quantity, and gross
domestic product (GDP) per capita is used as an economic factor. Eight indices are used for QoL.
Simple linear regression analysis is used to discuss the correlation coefficients between the three
indicators (EROIsoc, GDP per capita, and EC per capita) and eight QoL indices for 29 OECD and 37
non-OECD countries, and their annual changes over the 25 years from 1990 to 2015. We demonstrate
that the relationship between the three indicators and eight QoL indices changes annually and differs
between OECD and non-OECD countries. We also demonstrate that although GDP per capita is the most
influential factor among the three indicators for the Human Development Index (HDI), which is one
of the best-known composite indices of well-being, the importance of GDP per capita for non-OECD
countries has declined, especially in times of increasing energy prices, while the importance of EROIsoc
for OECD countries has increased.
