Recently, World Energy faced a serious problem. Energy consumption is growing steadily, and supplies of fossil fuels, which are the basis of the traditional power, are limited. For example, the supplies of oil will be over in 50-70 years, gas in 50-60 years, and coal in 600 years . Many scientists see the way out of this situation in development of alternative energy and promoting renewable energy sources.
Today, the international community pays much attention to the development of renewable energy making it an important area of public policy. Well-funded state programs to develop alternative energy began to appear all over the world. Regulatory and legislative acts, which increase the use of renewable energy, have been accepted .
The main advantages over other traditional energy sources are their renewability, safety, prevalence, and availability.
The main disadvantage of the alternative energy technologies is the high cost of electricity.
Another disadvantages of alternative energy include low efficiency , variability of work , expensive repairs, and maintenance.
Biofuel is a type of alternative fuel, produced from biomass - raw materials of plant or animal origin. The most common are bioethanol and biodiesel.
Bioethanol is produced mostly from corn or sugarcane. Bioethanol is the most common in Brazil, the USA, and Sweden. It is not used in pure form, and mixed with fuel in different proportions. The main difference is that the raw material for their production is the biomass, i.e., all kinds of wastes such as the residual non-food parts of plants, wood chips, manure, etc. One of the representatives of biofuel is biogas, which is also called "sewer" gas. Biogas consists of methane and carbon dioxide. For its use in motor vehicles, it previously purified from carbon dioxide and yield biomethane. It is an analogue of the natural methane; the only difference is in origin. Biomass can also receive ethanol and diesel. Bioethanol and biodiesel provide exhaust in an environmentally responsible manner. However, their energy efficiency is lower than that of pure gasoline or diesel fuel. Also the engine output reduces and fuel consumption increases.
One of the major factors hindering the development of this sector is relatively high cost of biomass energy.
Another factor in the use of biomass energy is the proximity to the source of raw materials . This allows to get a sufficient number of relatively inexpensive energy.
In 2002, the U.S. electricity generated 9733 MW of biomass. 5,886 MW was produced from Agriculture and Forestry wastes, 3308 MW from municipal solid waste, and 539 MW from other sources .
Biomass has a lot of advantages. It contains a carbon neutral level. If biomass boilers are in good condition and work well, they produce very little smoke. Also biomass is a good way to use wood waste from Agriculture and Forestry. Biomass fuels generally have lower fuel consumption than conventional fossil fuels. Biomass fuels are enough energy efficient.
Also biomass has some disadvantages. Boilers need a lot of space because they are typically larger than gas or oil ones. They also require a lot of space for storing fuels . Biomass production is sometimes dependent on seasonal crops such as corn for ethanol production. This makes it impossible to produce this biofuel all year round .
In conclusion, we can see that renewable energy is a very progressive thing and it is future. It is making a visible progress presently and is worth attention because it can save the world which is searching for cheaper and safer energy resources. So, it is very important to develop biofuel sector because it has many advantages over traditional fossil fuels and is a perspective source of energy.
