In Austria majority of people disagree with using nuclear energy. There are two main reasons. The first one is the issue of unsolved nuclear waste disposal and the second one is a risk radioactive leakage. These concerns are well founded, however in the Czech Republic if we want to be energetically self-sufficient and environmentally friendly we have no other option than to use nuclear energy. We cannot burn coal, solar and wind power would not be sufficient to meet the energy needs of our country and in contrary to Austria, we have almost no opportunity to use hydro energy.

The possibility to use energy from renewable resources is highly influenced by geography. The hydro potential in Austria is huge, more than 60 % of electric energy is made out of hydroelectric power plants. On the other hand, in the Czech Republic only 3 % of electricity is made in hydroelectric power plants. The potential of Czech rivers in almost fulfilled. Further expansion is very limited due to unfavourable conditions. If the Czech Republic started to build new hydroelectric power plants, it would be feasible only with huge investments and even then the amount of electricity generated by those power plants would be very small.

As for other renewable resources, solar and photovoltaic panels can be used for electricity production only during period of sufficient sun light, which is mainly from October to March. Those energy resources can be used as side resources for households or small networks of consumers, not for big cities, industry or even whole country. As we could hear during our excursion in solar factory, the energy also cannot be used for the whole year without a storage system. Disadvantages of the chargers are that they are very expensive and have quite short lifespan. On the other hand, very positive from the sustainability point of view is that 100 % of parts of certain types of PV panels are recyclable. Moreover, average lifespan of panels is 25 years, but they could work even longer with reduced efficiency. On top of that, the development is moving forward rapidly and solar energy is becoming more profitable and cheaper.
