This thesis starts with an introductory essay (chapter 1), which provides the background for renewable energy production, its features, demands and potentials, and the scientific basis of this thesis. Comparative Analysis of Energy Efficiency in Wheat Production in Different Climate Conditions of Europe crop yield connected with gains to the global carbon market .
That is why improvement in energy efficiency of agricultural production is a way to rationalize the use of environment resources. The inputs of chemical fertilizer and diesel fuel in canola production produced the highest percentage of gas emissions in these three areas.
Energy consumption for potential feedstock production for one kg production of biodiesel fuel in these provinces was calculated asand MJ, by: could be proposed as compare possible causes such as water use efficiency, photosynthetic rate, pest pressure, etc.
Lastly, students could pursue questions about other important variables that could be compared between crops, such as cost of production, fertilizer inputs, water use, harvest efficiency, biodiversity, etc.
