Biofuels, like fossil fuels, come in a number of forms and meet a number of different energy needs. The class of biofuels is subdivided into two generations, each of which contains a number of different fuels that will be explored in this article. First Generation Biofuels First generation biofuels are made from sugar, starch, or
In ecology, biomass refers to the entire mass of all living things in a given area or ecosystem at any one time. In other words, if you were to account for the mass of every living thing in a given area at a given time you would be calculating biomass for that area. According to
What are Biofuels? Biofuels are designed to replace gasoline, diesel fuel and coal, which are called “fossil fuels” because they are made from animals and plants that died millions of years ago. Biofuels are made mostly from plants that have just been harvested. There are three main types of biofuel. Ethanol, biodiesel, and biojet fuel.
A biofuel in any type of fuel in which the energy derived from the process of biological carbon fixation. Biological carbon fixation occurs in living organisms. The biggest difference between a biofuel and a fossil fuel is the time period over which the fixation occurs. In a biofuel, fixation occurs in months or years. In
