Trends and contexts of development of the energy sector

The world is nowadays dependent on energies, which become scarcer and scarcer. Petroleum reserves are shrinking and it is necessary to find new suitable substitutes. Energy consumption is increasing and energy crises are threatening the whole world. This caused price increased of all energies. Prices and consumption can decrease because of economic crisis, however when recession is over prices of energies are likely to grow again. Economic crisis can cause energy sources are predominantly located in politically unstable countries and other countries are dependent on them. National strategies on energy sector are therefore crucial. The Czech Republic with other countries consumes more energy than actually needed. Savings on energies are becoming more important. The production and consumption of energies have harmful by-products polluting the environment which is not desirable. Renewable resources are much less harmful to the environment but their consumption is still limited. Big potential could be also in nuclear energy and coal power plants with new technologies. The goal of this paper is to analyse individual indicators of energy sector of the Czech Republic and compare it internationally, set the strengths and weaknesses of this sector
