Several Western Balkan states face the consequences of the Yugoslavian war, which left hometowns with dilapidated electricity grid connections, a high average age of power plant capacities and low integration of renewable energy sources, grid bottlenecks and a lack of competition. In order to supply all households with electricity, UNDP Croatia did a research on decentralized supply systems based on renewable energy sources. Decentralized supply systems offer cheaper electricity connections and provide faster support to rural development. This paper proposes a developed methodology to financially compare isolated grid solutions that primarily use renewable energies to an extension of the public electricity network to small regions in Croatia. Isolated grid supply proves to be very often a preferable option. Furthermore, it points out the lack of a reliable evaluation of non-monetizable aspects and promotes a new interdisciplinary approach.

This paper intends to give an overview on some results of our studies carried out on the public opinion of the above aspects (settlements’comfort level and the use of renewable energy sources) directly or indirectly linked to the topic of climate change and possible adaptations.These studies were carried out by applying questionnaire survey in the (altogether 25) settlements of the Gyöngyös Micro-region.Knowledge on general human perceptions related to climate change and its impacts is considered to be important as it should advance theelaboration of adaptation and applied scientific works. They are highly required as rural areas, due to their closer relationship (dependence)to the physical environment, are more susceptible to changes resultant from the climate change with their possibilities to adaptation alsobeing impeded.The beauty of environment plays an important role in the settlements studied within the micro-region with more than two third of polleesopting the environment as a factor they most proud of, especially among those residing in the villages for more than 10 years. It can bepresumed that any change in this environment would greatly impact their everyday life and emotional relationship to their home villages. Theoverall picture after analysing the public opinion on the use of renewable energy source (as possible way of adaptation to the impacts ofclimate change) is rather controversial. Even basic knowledge and information are limited regarding the relevant technologies callingattention to the importance of raising environmental awareness and providing full information seems to be essential and should beimplemented, through the media and education.

An overview of research activity in the area of powering base station sites by means of renewable energy sources is given. It is shown that mobile network operators express significant interest for powering remote base stations using renewable energy sources. This is because a significant percentage of remote base station sites on the global level are still diesel powered due to lack of connections to the electricity grid. Besides huge expenses that mobile operators pay for diesel fuel and its transport to base station sites, it is pointed out that such base station sites represent major pollutants due to enormous green-house gas emissions. Since base stations are major consumers of cellular networks energy with significant contribution to operational expenditures, powering base stations sites using the energy of wind, sun, fuel cells or a combination gain mobile operators’ attention. It is shown that powering base station sites with such renewable energy sources can significantly reduce energy costs and improve the energy efficiency of the base station sites in rural areas. In addition, technical descriptions of the different power supply systems based on renewable sources with corresponding energy controllers for scheduling the flow of energy to power base station sites are discussed. According to the presented, hybrid systems which combine different renewable energy sources outperform those with only one energy source, and depend on the configuration of base stations installed on a particular site, such systems can offer autonomous functionality throughout the year.

Micro Grid

To make micro grid with renewable energy and to over come the technical challenges and economy base and policy and regulatory challenges . From the natural wastage we can generate the Electricity. Thus, the Electrical Power or Electricity is available with a low cost and pollution free to anyplace in the world at all times. This process divulge a unequaled step in electricity generation and this type of generation is maintain the ecological balance. We can have an uninterrupted power supply irrespective of the natural condition without any kind of environmental pollution. More influence this process relent the less production cost for electricity generation. Micro grids have long been used in remote areas to power off-grid villages, military operations or industrial projects. But increasingly they are being used in cities or towns, in urban centers. Here we try a proto type of micro grid with renewable energy sources.
