The pie chart compares the shares of 5 different resources used for producing energy in an unspecified in the years 1995 and 2005.

Overall, the country mostly relied on coal and gas in order to produce energy in those years with the former remaining the main source. Additionally, more nuclear and other resources in 2005 were used compared to the ones in 1995, whereas the opposite was true for petrol.

In 1995, coal, gas, and petrol were primary resources in electricity generation with coal sharing a slightly higher proportion. In more detail, the percentage of coal used to generate energy was 29.80% while the figures for gas and petrol were 29.63% and 29.27%. By contrast, nuclear and other resources had smaller shares in the manufacture of electricity (6.40% and 4.90%).

In the second year, the percentage of petrol in energy supply dropped surprisingly by around 10%, while the rates for gas and coal rose to approximately 30.31% and 30.93%, respectively, with the latter remaining the dominant resource. In a similar manner, nuclear and other sources saw an increase in their shares, accounting for about 10.10% and 9.10% of total energy generation in 2005.
