The renewable energy sources could be used in energy production, while no or only very slightly emit harmful substances to the environment. The solar, wind, hydropower, biomass and heat rational utilization of land contributes to greenhouse gas emissions.
Renewable energy sources also reduces the dependence on fossil fuels, thus contributing
The energy independence very important for the European Union, while simultaneously sparing the natural environment in order to increase the use of renewable energy sources . A further development is the key issue of how renewable energy sources available can be better utilized to improve the efficiency of economic competitiveness. EU renewable... energy policy is determined by five principles : The first is the environment, including the carbon dioxide and other pollutants to reduce emissions . The second increase energy security and at the same time reducing dependence on imports. The third aspect of local and regional development. With this realignment of economic and social development levels of different areas they want to achieve. This point is closely related to rural development and create new jobs . The transformation of the agricultural structure is an important aspect , which is that they can reduce the overproduction of food by providing alternative land use options , such as the cultivation of energy crops.

Nowadays the technology which can process ligno cellulose and break down into fermentable sugars is being researched. One possible field of use of biomass is the liquid fuel production such as ethanol production. Based on the literary life cycle analysis, I compared the starch-based (first generation) to cellulose-based (second generation) bioethanol production in my study considering into account various environmental factors (land use, raw material production, energy balance). After my examination I came to the conclusion that the use of bioethanol, independent of its production technology, is favorable from environmental point of view but the application of second generation bioethanol has greater environmentally benefits.
Under the „Molecular farming” research program (product vaccines and substances for medical use with gene manipulated plant) in 2007 in UD Centre for Agricultural Sciences and Engineering Faculty of Agricultural Science Institute of Horticulture Department of Plant Biotechnology experiments were launched to transform tobacco plant by PAF an...tifungal protein. Our aim was to learn the transformation technics. We chose the
Nicotiana tabacum and PAF as model systems.
Our work was to express several different paf constructions in plants with nuclear and plastid transformation too. After that we confirmed the presence of paf gene in the level of DNA and RNA.
Under the GENOMNANOTECH Debrecen Regionális Egyetemi Tudásközpont (GND RET) research program in summer 2007 in UD Centre for Agricultural Sciences and Engineering Faculty of Agricultural Science Institute of Horticulture experiments were launched to transform tobacco plant by plastid transformation technics.
Our aim was to adopt first in
