The current technical and economic conditions for renewable energy production makes it not a marketable activity. In order to ensure sustainable development, the energy produced from fossil carrier should be reduced, and its place should be taken by renewable energy sources. The European Union regulation says that until 2020 the renewable energy sources should take 20 percent of the whole energy production. The EU countries have developed various support systems to support electricity production from renewable energy sources. These systems have been continuously improved over time, just as the feed-in system used in Hungary (FIT).
The thesis will be presented general models of support systems, discussing their advantages and disadvantages as well. With the history and development of the support system used in our country I present the Hungarian feed-in balance group in detail, covering the expected changes in the near future. Then I compare it with the support system used in Germany.
The known model will be examined in economic way using the data available for the years 2011 and 2012. I examine what kind of unit cost the renewable energy production has, and what kind of effects the renewable energy sold on the organized electricity market has.
