Although the Czech Republic is a relatively small country it is faced with the problem of balancing energy production against the available resources of energy-producing raw materials. The Czech Republic is atypical of the EU countries because it is one of a few countries that presently exports electric energy and, at the same time, is still producing uranium ores. Resources of all the essential energy-producing raw materials exist in the Czech Republic, though, temporarily, only brown coal and bituminous coal reserves cover the immediate needs of energy production, while uranium ores are sufficient to satisfy the demands for a long period in the future. This paper provides data on the deposits of raw materials useful for energy production in the Czech Republic and their lifetimes, as well as the proportions of different energy sources.
