In recent times, biofuels are becoming one of the main focuses of chemistry as a science. These fuels are getting more and more mentioned as one of the perfect renewable energy sources, which reduces emissions of harmful gases and substances in the environment. But things are not so ideal. Production of biofuel leads to some moral questions.
Biofuels are considered to be renewable sources of energy, which are obtained by processing biomass. In recent years consumption and production are stronger and are slowly beginning to replace fossil fuels. There are different varieties of biofuels, which are divided into two main generations, depending on the raw materials that are used for production, price, production costs and emission levels of carbon dioxide. The first generation is mostly based on the production of sugar, starch, vegetable oils and animal fats, while the second generation is based on agricultural and forest waste. Biofuels in the modern world came as a fuel to reduce emission of carbon dioxide.
But this is not really completely true. Studies that have been done recently, show that biofuels contribute more to global warming than fossil fuels. The reason is simple. Modern biofuels are mostly produced from plants, which during the entire life cycle absorb carbon dioxide, and when this fuel is burned, it relieves carbon dioxide. Also, in the distribution and production of biofuels, additional amounts of carbon dioxide are produced.
There are many more interesting properties related to biofuels, but in order to understand most of the topics related to biofuels, one should also have basic knowledge of sciences like chemistry. Some basic principles can easily be learned from useful sites that contain chemistry tutorials.
