'''CRITIQUE'''

The first negative thing about alternative fuels such as biodiesel and biomass is the need of a large initial investment, which could be problém for expansion of thhe technology to poorer countries or regions.Therefore there is a big need of state subsidies, but as we know, they aren’t inexhaustible and infinite. There is also a big risk, that the resulting income will be much more lower than the expected income, due to the changing market prices in time. As our guide mentioned there is also a problem with sufficient capacity of the region needed to grow rape, therefore we don’t understand why are the photovoltaic cinstructions places mainly on the ground. We think that the company should for example try to use a free place on the roof to reduce a simply bulit-up area. Also resources needed for production of biodiesel are more and more limited, which leads to the growth of prices of the resources which naturally also leads to the growth of the price of the biodiesel. This process then disadvateges smaller manufacturers. Of course that we could find many other controversial aspects.
