Today, the situation is of such a nature that man is the cause of the environment, these can cause irreparable damage. This is in large part the result of the irrational use of natural resources. One of the most important tasks of ecology is to preserve and enhance natural resources.
The environment and energy efficiency are two concepts that are inextricably linked to each other. Every day, we use electrical energy to organize my life. Thermal power plants, which supply us with the energy of the most polluting industries. It is obvious that if we want to keep our planet alive and healthy, we need to use this energy economically, and appropriately. Thus, we are able to reduce the damage caused by the power plant could cause to the nature.
Energy and the environment
The level of development of the company, which is determined by the amount of energy that is consumed by a single person. Today, the main sources of energy are oil, coal and gas. Work, heat, and electrical consumption of the boiler and of the thermal power plant, in different ways, the impact on the environment:
- in the atmosphere of our planet receives a large amount of hazardous waste
- the tanks mitigate the harmful substances and the heated water,
- the consumption of large amounts of oxygen,
- a large area of land to be used for the disposal of waste and for the disposal of waste.
The contamination of soil, water and air, leads to the so-called greenhouse effect. Causing the temperature of our planet rises and thus run the other if statement below. It should also be noted, however, that the following energy sources such as oil, gas, and coal, it is very difficult to obtain, and therefore, in a short period of time due to its irrational use, it can dry out.
An alternative source of energy
The modern teaching of the strive to find alternative energy sources.
The term "source power" refers to natural substances or phenomena that allow people in order to get the energy.
An alternative source of energy, which is in contrast to the traditional sources. Traditionally, as we have pointed out above, and shall include oil, gas, and coal. Alternative sources are needed in order to reduce the negative impact of traditional energy sources, which is harmful to the environment. There are resources that can be provided for alternative energy:
- the energy of the sun
- wind energy
- the energy of the water
- the energy of the earth
- those
Solar energy is energy derived from solar radiation. Solar energy is considered a renewable source of energy. The term "renewable" refers to the inexhaustible sources of energy. The advantage of this type of energy is its environmental friendliness, it is the process of energy production does not mean that the emissions are hazardous waste and do not pollute the environment. The sun's energy is produced using solar energy. This type of energy has both advantages and disadvantages. The advantages include the availability of, and, as noted above, the complete security for the environment.
The down side is that, depending on the weather conditions and the time of day, so that it is a form of energy, it can be used regularly, only in certain climate zones. The weakness is also true, and the high cost of such plants, such as are used in their production expensive items. The harnessing of solar power stations requires the use of a large area.
Wind power is produced by transforming the kinetic energy of the wind into the atmosphere in any other form of energy. For this purpose, a wide range of devices, such as wind turbines, windmills and sails. The power generated from the wind, it is also in the field of renewable energy. In addition, the wind energy is available, and it is safe for the environment. The advantages of the use of the wind energy sector can also be attributed to the fact that the windy conditions of the plants, which are easy to maintain, and which does not require the time consuming installation and high cost.
But, of course, there are some disadvantages, for example, the capacity of such plants does not depend on the person, and will depend on the nature, that is, the force of the wind. The minor disadvantages of some of the opponents of this technology include the danger of a bird, the poor TV reception and radio signals, the changes in the landscape.
The essence of the spirit of the energy to convert the kinetic energy of the water mass into electric energy. Power is generated using water power. The strength of the water flow affects the turbine, producing electricity. The advantage of using these units is the fact that this is the source of energy is inexhaustible. In addition to this, hydroelectric power is safe for the environment. The energy obtained in this way are relatively cheap. Along with the advantages there are also disadvantages, such as dependence on weather, climate, and natural conditions. For the construction of the station only in the specific area. Another disadvantage is that the energy obtained in this way, it is difficult to implement at a later date.
In the scientific community, the electrical power is generated using thermal energy from the bowels of the Earth, is called geothermal energy. To get through the use of a geothermal power plant. While it is cooling down our planet emit massive amounts of energy, which is thousands of times more than emitted by burning fossil fuels. Earth power is a renewable source of energy. The advantages of this method is the production of electrical energy can be attributed to the fact that it does not depend on the environmental conditions. The disadvantages include the high cost of construction and maintenance of such a device. It is also believed that such a station, it can not be called completely safe for the surrounding environment as a result of the vapor that may contain harmful substances.
The term biofuel refers to a fuel that is derived from animal or vegetable raw materials. Those can be of three types:
- the firm
- the current
- gaseous
A solid biofuel, that is wood, wood chips, straw. Today, people grow the particular power of the forest, which is composed of the rocks of the rapid growth of the tree.
The liquid fuel is under-represented in particular bioethanol and biodiesel. Bioethanol is mainly produced from sugar cane and maize (corn). Biodiesel is produced from fats of vegetable and animal origin.
Gaseous biofuels, biogas, bio-hydrogen, methane. The biogas produced from the products of fermentation of organic waste. Bio-hydrogen is the hydrogen that is received from the biomass, thermo-chemical or biochemical methods.
The completion of the
However, scientists have been struggling to reduce the amount of resources that the world consumes energy. Every day, the energy needs of more and more money with less. At the present stage, it is important that you learn how to maintain and rational use of energy derived from traditional sources. Even more important is the development of a new, inexhaustible, environmentally friendly source of energy, it will be of help for a number of years, to keep our environment alive and healthy.
