Future possible uses of renewable energy in the V4 countries

Nowadays the number of the population of the World is over 7.3 billion, which was less than 4 billion at the beginning of the 1970s. That was one of the reasons why in the last 40 years the utilisation of fossil minerals increased rapidly. The stocks of these resources are limited, so we need to find another way which helps us to substitute them in the future and also to increase our efficiency and sustain our natural environment. The use of the limited resources has also increased in Europe and it holds true in the V4 countries, too. That is the reason why this question is also important in the V4 countries, but the natural possibilities are different. The goal of the countries is to find those alternative or renewable energy sources which could be suitable for solving this problem, and boost the economy instead of destroying their natural environment. In this paper I compare the energy utilisation of V4 countries in the past, the structure of the fossil and renewable energy usage nowadays and examine those possibilities (wind energy, solar energy, geothermal energy, biomass), which can help them reduce their energy dependency from other countries. These countries need to increase the ratio of the utilisation of renewableand alternative resources in the future if they want to satisfy their population demand.
