- Abstract
The purpose of this article is to analyse the progress after 3 decades of efforts to migrate to renewable energies, specifically non-conventional renewables. Data on final energy production and consumption were analyzed by regions, as defined by the International Energy Agency (IEA), and a timeframe between 1990 and 2018. Although the production of renewables in the last three decades almost doubled, the share of different types of energy sources did not change substantially: the percentage of energy produced with fossil fuels in 2018 accounted for 81% of the total, just as in 1990. Total energy consumption from renewables went from 15,4% in 1990 to 15,9% in 2018. Non conventional renewables went from 0,1% to 1,9% in the same period of time. In 2018, Iceland was the economy with the highest percentage of final energy consumption coming from non-conventional renewables, with roughy 42% from geothermal energy. Denmark ranked second, with 10% of the final demand supplied with non-conventional renewables. It was found that smaller-scale economies allow higher participation of non conventional renewable energies, while renewables generated with biomass and hydropower have a greater scope for larger-scale energy matrices. However, environmental impacts related to conventional and non-conventional renewables must be considered, if the environmental cost of development is intended to be reduced.
