Today, the situation is like that of the man in question to the environment is irreparable damage. This is largely related to inappropriate use of natural resources. One of the most important tasks of ecology is to maintain, and the expansion of the use of natural resources.
The environment and energy conservation are the two concepts which are inextricably linked. Every day we use the electric energy to the organization of their daily lives. The thermal power plants that provide the energy for the more polluting the production environment. Of course, if we want to keep our planet alive and healthy, we need to use that energy efficiently and is appropriate. Therefore, we are able to reduce the amount of damage that the plant is a cause in nature.
Energy and the environment
The level of development of the society, in particular, the amount of energy that is consumed by a single person. Today, the main sources of energy are oil, coal, and gas. The work of heat and power in boilers and TPP are several way to have an impact upon the environment.
- the atmosphere of our planet has been a great deal of waste, which is harmful
- in the bodies of water to alleviate any harmful substances, and water
- it is used in a large amount of oxygen,
- large tracts of land that are used at the waste site and burial.
The pollution of soil, water and air, leads to the so-called greenhouse effect. Leaving the temperature of our planet increases, and, thus, are executed in the other which is irreversible. Thus, it should be noted that these sources of energy, such as crude oil, natural gas, and coal, it is very hard to is met, which means that in the near future due to its improper use, they can dry up.
Alternative sources of energy
The modern doctrine, is struggling to find alternative sources of energy.
The term "source power" refers to substances which occur in nature or in the phenomena that make it possible for individuals to get to energy.
Alternative sources of energy opposed to the more traditional sources. The traditional one, as has been pointed out above, which include oil, natural gas, and coal. Alternative sources are needed in order to reduce the negative impact that the traditional energy sources that are harmful to the environment. There are resources that are capable of providing alternative energy
- the power of the sun
- wind power
- the power of the water
- the energy of the earth
- biofuels
The solar energy obtained from solar radiation. Solar energy is considered a renewable source of energy. The term "renewable" implies an inexhaustible source of energy. An advantage of this type of energy is its compatibility with the environment, that is, the process of obtaining energy does not involve the emission of harmful residues and do not pollute the environment. The solar energy by receiving it through the power of the sun. This type of energy has its advantages and disadvantages. The advantages include the availability of, and, as has been said above, to be totally safe for the environment.
On the other hand, refers to the dependence on weather conditions and the time of day, due to the fact that this is the kind of power that you can use regularly, only in certain climate zones. The disadvantages are also applicable, and the cost of such power plants, as well as in their production, they are used for expensive items. Also, the exploitation of solar power stations requires the use of a large area.
The use of wind energy is produced through the transformation of the kinetic energy of the wind into the atmosphere in any other form of energy. To do this, they use a variety of devices, such as, for example, wind turbines, windmills, and sailing. The energy obtained from the wind, and also relates to forms of renewable energy. In addition, the use of wind energy is available and safe for the environment. The advantages of the use of wind energy, it can also refer to, and the windy mill is easy to maintain, does not require the installation and increase costs.
But, surely, there are some drawbacks as well, such as, for example, that the power of such a power plant does not depend on the man and depends on the nature, that is to say, from the force of the wind. The negligible cons of some of the opponents of this technology are related to the danger to the birds, to the deterioration of the reception of tv and radio signals, the changes in the landscape.
The essence of the water-power industry, is to convert the kinetic energy of the mass of the water into electrical energy. The energy that is received by using the hydroelectric power. The force of the water flow from the impact of the turbines, which produce electricity. There is no doubt about the advantage of using such systems is that this is the source of energy is inexhaustible. In addition to this, the dam is safe for the environment. The energy absorbed in this way, it is easy on the wallet. Along with those there are also disadvantages, such as, for example, the dependence on the weather, the climate, and the natural environment. Building stations is only possible in certain locations. Another disadvantage resides in the fact that the energy obtained in this way, it is difficult to maintain the implementation at a later date.
In the scientific community that the energy, obtained from thermal energy inside of the Earth is called geothermal energy. Digged it, by the use of power from geothermal energy. In the introduction to the our planet emit an enormous amount of energy, which is thousands of times greater than that of the stresses from the use of fossil fuels. The energy of the Earth is a renewable source of energy. The advantage of this method is the extraction of electricity can be, and that it does not depend on the condition of the environment. The disadvantages include the high cost of construction and maintenance of such plants. Also, it is assumed that this type of plant can not be called completely safe for the environment, as well as the results of the station work, the steam, which may contain substances harmful to our bodies.
Under the concept of biofuels is seen to fuel that is produced from an animal, or plant life or health. Biofuel can be of three types:
- the firm
- the net
- the gas
The firm, biofuels, is the wood chips, and straw. Now, a man grown energy, particularly the forest, which are made up of rocks, of trees, of rapid growth.
Oil is represented mainly in the bioethanol and the biodiesel. Bio-ethanol is mainly produced from sugar cane and corn. Bio-diesel is produced from fats of plant and animal origin.
Gaseous biofuels to be introduced for biogas, bio-hydrogen and methane. The biogas that is produced on the basis of the products of the fermentation of organic waste. Bio-hydrogen is the hydrogen that is received from the biomass, thermo-chemical or bio-chemical manner.
Conclusion
Today, scientists are striving to reduce the consumption of natural resources, which mankind spends on energy. Each and every day for energy, it requires more and more resources continue to be less and less likely. At this stage, it is important to learn how to save and rationally to the energy obtained from traditional sources. Even more important is the development of a new, endless, promises, to sources of energy that will help you for many years to save our environment lively and healthy.
