About what kind of energy is most accessible and appropriate in the context of the struggle for environmentally friendly space, scientists from many continents have long disputed.
And today there are several versions on this matter.
Traditional electricity: the views "for" and "against"
Many specialists are still the cheapest andAn advanced source of energy is the electricity produced at nuclear power plants. Peaceful atom can generate electricity, which is about four times cheaper than produced at a small hydroelectric station.
The nuclear power plant does not pollute the atmosphereHarmful substances. Absence of emissions saves costs for treatment plants. Only 1 kg of isotopic substance replaces the use of 3-3.5 thousand tons of coal. To operate smoothly for several years, the average size of the nuclear power plant will require no more than 30 kg of fuel. In addition, the raw materials are obtained in the laboratory. Consequently, it is not necessary to develop a bulky mining of fossils and there is no territorial linkage to water bodies. This is the opinion of the supporters of nuclear energy.
A nuclear power plant can produce electricity at all times, in any geographic location.
Their opponents give quite different figures,Calling enormous expenses for waste disposal and liquidation of consequences of various scale of accidents. They also point to the initially high cost of installing such facilities. Nevertheless, today nuclear energy is the most affordable source of energy necessary to maintain the growing technical potential in Europe.
Myth and reality: the cheapness of alternative energy sources
In modern society, there are oftenTransition to renewable natural energy sources. There is an opinion about the low cost of wind energy: easy operation, quick payback of the installation, low depreciation, inexhaustibility of the resource. A significant disadvantage of wind turbines is a strong dependence on the movement of air masses and the volatility of the produced capacity. Due to the instability of work, such plants can not be considered to be producers of cheap energy.
Scientists will use the solar energy for a great future. At the moment, it is the energy of the sun that is the most accessible and stable of all alternative options.
Scientists are working to accumulate solar potential to exclude dependence on weather conditions.
In Japan, the first power plant using solar radiation appeared. Perhaps the world is on the verge of opening a new environmentally friendly and cheap energy source.
