Abstract:

Environmental goals include reducing carbon dioxide emissions, which is one of the most important motivations for the introduction of alternative fuels. A couple of years ago, biofuels were in high demand, not only because they represent an evolutionary change and can gradually replace traditional fossil fuels, but also because they seemed to be the surest eco-friendly solution. Of course, it is becoming clear that the aggressive introduction of biofuels at any cost can lead to many negative impacts on the environment. This article attempts to make some comparison between the environmental impacts of biofuels, traditional fossil fuels, as well as some other alternative fuels or driving modes (hydrogen and battery electric vehicles).

Keywords: alternative energy sources, fossil fuels, carbon dioxide, biofuels, bio-products, hydrogen and battery electric vehicles
