The use of renewable resources has been on the rise in recent years. The use of renewable resources is also related to state support, either in the form of a fixed price for the purchase of energy or in the form of direct investment aid. The present article analyzed the use of RES in the Czech Republic and the number of installations depending on state support, which represents a significant factor affecting the end user. The article presented the development of the legislative framework that formed the basis of RES support during the years since independence and the country’s entry into the EU. The breaking points of support, when support was increased, and the impact of this support on the number of new installations were indicated. The development of energy production from RES was analyzed on the basis of historical data. A numerical model using a neural network was developed to illustrate the impact of government measures. The time interval for training the network was chosen on the basis of legislative changes, while the possible course was monitored if the change did not occur, or if the support remained the same. The results of the numerical simulation point to the fact that without adequate legislation and state support, there would probably not be an expansion of the use of RES. On the other hand, if the initial high support were to remain, there would probably be a significant distortion of the energy market. Finally, a prediction for the near future was presented, while a stabilization of the situation was assumed.
