Research done so far mostly relates to the impact of climate change on electricity production from renewable sources by exploring the impact of meteorological parameters on production potential and analysing possible scenarios for future periods. For example, in 2013, two studies were carried out, one related to wind power plants (the impact of climate change on wind power generation, in particular the impact of wind speed change on production), the other to hydroelectric power plants (research that most meteorological parameters have on electricity generation from the meteorological parameters to assess the need for electricity generation from hydro power plants with the aim of planning the production and management of the system, as well as determining the potential output) [51] [52]. The paper exploring the possible impact of climate change on the energy generation from renewable energy sources in the Republic of Croatia, such as photovoltaic and wind power plants, as well as hydropower, was carried out in 2012 [53]. The climatic data used in the research are retrieved from the global climate model ECHAMS-MPIOM, and the data are dynamically adjusted to the RegCM regional climate model in DHMZ. The results based on the IPCC A2 scenario for the two future periods, 2011-2040 and 20412070, were analysed. It was concluded that climate change could have the greatest impact on renewable energy sources in the coastal part of the country, and an increase in production is expected due to the increase in wind speed, but also reduction of production from hydro power plants. Significant changes in photovoltaic power generation are not expected.
