Alternative Fuel

The problem of environmental protection is one of the primary concerns of the contemporary society because the pollution of the environment threatens to the future generations of all people and the survival of the mankind at large.

The search of alternative sources of energy and alternative fuel is one of the priorities in thedevelopment of preventive measures targeting at the protection of the environment from the further pollution and ongoing deterioration of the environmental situation. At the same time, it is necessary to analyze positive effects of the wide implementation of alternative fuelsand assess the extent to which they may be effective.

First of all, it should be said that the introduction ofalternative fuels and thedevelopment of alternative sources of energy is vitally important for the survival of humans. In actuality, the modern world is highly dependent on fossil fuels, such as oil and gas. The modern industry and transport cannot function normally without the use of fossil fuels since there are no alternatives that can totally substitute them at the moment. At the same time, fossil fuels are the major source of the pollution of the environment because the use of fossil fuels leads to the emission of CO2 and other gases and dangerous elements that pollute air and environment at large. Consequently, the more people use fossil fuels the more they pollute their environment. Hence, the only logical solution of the problem of the protection of the environment is the minimization of the use of fossil fuels and the total ban of the use of these fuels. But this measure will need the use of alternative fuels and sources of energy.

However, there is another reason determining the necessity to develop new,alternative fuels and sources of energy. To put it more precisely, fossil fuels are scarce resources. Therefore, there is a limited quantity of fossil fuels on the planet and their substitution by alternative fuels is simply inevitable. In such a situation, the major problem is the search of effective alternative fuels that could be widely used in the world. Basically, the major alternative to the fossil fuels polluting the environment is considered to be electricity, which may be generated using alternative fuelsand sources of energy. In this respect, it is possible to name a variety of alternative sources of energy, but many of them have certain limitations in the practical implementation.

For instance, it is possible to name the solar energy as an alternative source of energy which could transform the solar power and generate electricity. However, the major problem is the lack of the sufficient amount of solar energy in some regions (Deudney and Flavin, 112). For instance, in Northern regions, the amount of solar energy is consistently lower compared to Equatorial regions. Consequently, the use ofsolar energy in Northern regions will be limited. Also, it is possible to use the wind power as a source of energy. Basically, the wind power may be used to generate electricity similarly to the solar power, but it also has its own limitations because it is dependent on the environmental situation, i.e. on the wind.

However, it is necessary to underline that both alternative sources of energy named above can generate the electricity that may be used in industry as well as intransport and satisfy practically all needs of people, naturally, on the condition that the sufficient amount of electricity is generated. In this respect, it is worth mentioning the fact that many car manufacturers have launched programs of the development and production of hybrid cars, which use alternatives, such as hydrogen, but the most widely spread source of energy for hybrid cars is electricity.

Potentially, the wide use of the alternative sources of energy and fuels will reduce the amount of emissions of dangerous gases and the pollution of the environment substantially. In addition, it is possible environmentally friendly technologies which can minimize the impact of humans on their environment. For instance, it is possible to use ground heat for heating buildings, instead of conventional heating systems. On the one hand, this will reduce the consumption of fossil fuels, while on the other hand, the ground heat does not require the use of any natural resources, but it exchanges the heat between a building and ground, minimizing interference of humans in nature.

Thus, it is possible to find various alternative sources of energy and alternative fuels which are environmentally friendly. However, they can hardly totally substitute fossil fuels in the modern world.
