Renewable energy applications were examined in animal farms. The investment support system for animal farms – which has renewable elements – has been summarized through analyzing the legislation and future prospects. The most important in this topic is the Animal Farm Modernization Support, which had several application periods during the 2007–2013 CAP budgets. For analyzing practical application of renewable energies interviews and farm visits have done in Hajdú-Bihar County. The questions covered the general attributes of the farms and the details of the (existing or planned) renewable energy application. In terms of economic analysis saving, the investment return time and the employment effect were examined. The results show wide variety of applied renewable energy application. The investment supports plays great role in renewable energy projects by lowering the return time; and through additional points in application assessing, which is an incentive for farmers to include renewable energy element in their modernization projects.

The Earth receives solar energy by way of radiated energy. Refers to quantum theory, light is made up of packets of energy, called photons, whose energy depends only upon the frequency or color of the light. In this research, evaluation of 3 PV modules technologies performed based on energetic points of view in 2011. The efficiency of the mono crystalline module field was calculated, the efficiency of the poly crystalline module field and the amorphous module field were calculated.

The technical set-up of the dairy farms has been examined in Hajdú-Bihar County between 2002 and 2012. The data were gathered by methodical observation and oral interviews. During the last ten years, modernisation at the companies had different types. The technical improvements caused that the  operations  can  be  done  with  less  time  expenditure  and  more  efficiency.  The  technical  solutions devices  of  dairy  farms  for  main  operations  have  been  classified.  It  has  been  established  that  the improved  technical  solutions  affect  the  labour  productivity.  Nowadays  this  mentioned  effect  is especially  important  because  good  practise  can  be  followed  by  other  companies/firms  thus  their efficiency and competitiveness could be improved.

The dairy farming sector needs constant modernization of its buildings, machines and technology in order to maintain its competitiveness and productivity. For the greater scale investments, these companies try to apply for state funds in addition to their own financial sources. Therefore, the investment support system plays a great role by improving the competitiveness and modernity of these farms. In the last 10 years, 7 funding programs were available for dairy farms. In this research, 25 dairy farms were interviewed in Hajdú-Bihar County. The examined farms cover more than 50% of the milk production in Hajdú-Bihar County. The survey questions focused on the investment funding program use of farms between 2007 and 2017 and renewable energy investments including all programs. The results show how many tenders were submitted, how many were successfully evaluated and completed. All farms had at least two successfully evaluated projects. A correlation was found between completed projects by farm size and completed projects. The connection of the modernity index of dairy farms and the completed projects was also shown.
