The energy sector plays a significant role in sustaining and developing of every economy and it is not a different case with an economic and political union like the European Union. In the last few decades there has been an ongoing energy transition in the world and in the European Union for the primary reason of stopping the climate change through the use of new technologies and energy sources. Such a trend can have a significant impact on different parameters of the energy sector which includes employment and skills that employees have to know in order to work in the new jobs that the energy transition is creating. Those new jobs are called green jobs and their share in the total jobs in the European Union has significantly increased in the last few decades. Their primary purpose is to protect the environment through a more efficient use of resources and to use energy from sources which have less of an impact on the environment. Green jobs require a more highly educated work force which can adapt to the rapid developments in technology. Employment in the energy sector of the European Union has seen some changes the last decade. There has been a decrease in the number of people employed in the parts of the energy sector which extracts crude fossil fuels but on the other hand has seen an increase in parts that use those crude oils to make other products. The age-sex structure of the European Union's energy sector primarily consists of male and older workers whose share is showing a gradual decrease. Salaries are mostly increasing but not at the same rate in the different parts of the energy sector.
