The energy generation for a particular country in 1995 and 2005, discriminating the type of source is compared by the two pie charts shown above.
In general, it can be clearly seen from the data, that the most significant origins of the power in the nation are represented by gas and coal, and have kept their shares, while only a slight increase of participation by nuclear and other sources has taken place in 2005 at the expense of a reduction in the representation of petrol.
On the one hand, whithin the categories remaining roughly stable throughout the time are gas and coal, each of them accounting for about one third of the power of the country.
On the other hand, the statistics allow to conclude that only one decade after 1995 the sources contributing the least, namely nuclear and others, have rosen their contributions by nearly doubling their respective percentages at the end of the time period; this increase coming accompanied by a reduction in the energy created based on petrol.
