Climate change is a threat to sustainable development. After years of extensive research, the scientific community agrees that man-made greenhouse gas (GHG) emissions are the dominant cause of the Earth’s average temperature increases over the past 250 years (IPCC, 2014).
One of the priorities of the Energy Union strategy is to increase energy efficiency in an attempt to reduce energy consumption by 32.5 % by 2030. Energy intensity is a measure of an economy’s energy efficiency and shows how much energy is needed in order to produce a unit of gross domestic product (GDP).
The share of renewable energy in energy consumption iincreased continuously between 2004 and 2018, from 9.6 % to 18.9 %. The Europe 2020 target is 20 % by 2020 and the Europe 2030 target is 32 % by 2030.
