Today the Situation is such that man adds to the environment irreparable harm. This is largely due to inappropriate use of natural resources. One of the most important tasks of ecology is that the conservation and enhancement of natural resources.
Ecology and saving energy are two terms that are inseparably connected to each other. Every day we use electricity for the organization of one's own life. Thermal power plants are energy, the external contamination environment of production. It is obvious that, if we want to save our planet safe and sound, we use should, this energy-efficient, and useful. So, we can reduce the damage to the wearing power of nature.
Energy and the environment
The level of development of the society depends on the number of energy consumed for a Person. Today, the most important energy sources are oil, coal, and Gas. The work of the thermal and energetic boilers and cogeneration in different ways influence on the environment:
- in the atmosphere of our planet, a large number of hazardous waste comes,
- in the waters of the harmful substances and the heated water relieve
- large amounts of consumed oxygen,
- great land, landfills and burial will be submerged under the waste.
Pollution of soil, water and air leads to the so-called greenhouse effect. Reducing the temperature increases on our planet and other irreversible effects will be triggered. It should also be noted that such sources of energy such as oil, Gas and coal, are very difficult to be replenished, and this means that in the short time due to their inefficient use, dry can.
Alternative Energy Sources
Modern doctrine search for Alternative energy sources.
The term "energy source" refers to natural substances or phenomena that enable people to get energy.
Alternative sources of energy traditional sources disagree. To the traditional, as we mentioned above, oil, Gas and coal. Alternative sources are needed to reduce the negative impact of conventional energy sources, the damage to the environment. There are sources in the Alternative energy:
- the energy of the sun
- Wind energy
- the energy of the water
- the energy of the earth
- Biofuels
The sun energy is from the solar radiation. Solar energy as a renewable source of energy. The term "renewable source" means the inexhaustible source of energy. Advantage of this form of energy, their environmental friendliness, i.e., the process of energy extraction from arising to pollute no Emission of harmful waste and the environment. The sun's energy with help of solar systems. This type of energy has both advantages and disadvantages. The advantage of availability and, as mentioned above, the full safety for the environment.
On the page, depending on the weather and the time of day, zones, because of what this type of energy can regularly only in certain climate. The disadvantages is the high cost of such power plants, because they are used in their production expensive items. Also the operation of Solar power stations requires the use of large areas.
The energy of the wind is by converting the kinetic energy of the wind into the atmosphere in any other Form of energy. To do this, use a variety of devices, e.g., wind generators, wind mills, sails. The energy from the wind, also belong to the renewable energies. In addition, wind energy is available and safe for the environment. The advantages of the use of windy energy, so can be and what power system to maintain windy easily, do not need any lengthy Installation-and cost-intensive.
But certainly there are also some disadvantages, for example, such a performance of the power plant does not depend on the people, but depends on the nature, that is, from the force of the wind. The disadvantages are negligible, some of the opponents of this technology are related to the risk for the birds, the deterioration of the reception of television and Radio signals, the changes in the landscape.
The essence of the water-power is to convert the kinetic energy of the water mass into electric energy. The energy is through the use of water power. The force of the flow of water, it has to produce an impact on turbines, the power. The undoubted advantage of the use of these systems is that this energy source is inexhaustible. In addition, hydropower plants are environmentally friendly. The energy in a similar way, pretty cheap. In addition to the advantages there are also disadvantages, e.g. the dependence on the weather, the climatic and natural conditions. Build stations can only in certain locations. A further disadvantage is that the energy, keep on this way, hard to for the realization to a later date.
In the scientific community's electricity, with the help of heat energy to the bowels of the earth, is called geothermal energy. Is reduced by the use of geothermal power plants. Upon cooling, our Planet an enormous amount of energy, which marked thousands of times greater than fossil fuels has. The energy of the earth is a renewable source of energy. The advantages of this method of extraction of electrical energy can be attributed, and the fact that he is not depending on the ambient conditions. Disadvantages are high costs for construction and maintenance of such systems. Also not true, that such a Station can be considered completely safe for the environment, since the operation of the Station, the release of vapor occurs, it can contain the harmful substances.
The term refers to biofuels in the fuel, obtained from animal or vegetable raw materials. Biofuel can be in one of three ways:
- Fixed
- liquid
- gaseous
Solid biofuels firewood, wood chips, straw is. Today, the man is breeding special energy forests, the rocks consist of fast-growing trees.
Fuel oil presents mainly Bioethanol and Biodiesel. Bioethanol mainly from sugar cane and corn. Biodiesel from fats of plant and animal origin.
Gaseous biofuels written by Biogas, Bio-hydrogen, methane. Biogas from the Fermentation of organic waste. Bio-hydrogen is the hydrogen from biomass Thermo-chemical or biochemical methods.
Conclusion
Today, scientists are struggling with the fact, to reduce consumption of resources mankind spent for the production of energy. With every day energy, you always need more, and the resources are always scarce. In the current Phase, it is important to learn to save and to consume rationally, and the energy from the traditional sources. Even more important is the development of new, inexhaustible, environmentally friendly energy is, it helps for years to save our environment alive and healthy.
