The pie charts compare the amounts of four different types of energy production in 1995 and 2005. Overall, it can be observed that the most substantial sources of energy in both years were gas and coal, which represented more than half of total energy production, whereas petrol and other types of energy sources produced the lowest amount of energy. Nevertheless, over a ten-year period, in all kinds of energy production, there was a marginal change. It is obvious that coal is one of the leading sources of energy production. If in 1995 the energy produced by coal was 29. 80%, then in 2005 this figure increased merely to 1% (30. 93%). As for gas, it is the second leading source of energy production. In 1995, its production generated 29. 63%, and 10 years later, this number slightly increased to 30. 31%. Regarding the remaining energy sources, production of nuclear power and other types of energy sources increased by 5%, which amounted to 10. 10% and 9. 10%, respectively. Moreover, petrol was the only source of energy, the production of which decreased from 29. 27% in 1995 to 9. 72% (19. 55%) in 2005.
