On what kind of energy more accessible and expedient in the fight for clean space are long disputes scientists from many continents.
And today there are several versions of this bill.
Traditional electricity: opinion "for" and "against"
Many experts and still the cheapest andbest source of energy is considered electricity generated at nuclear power plants. Peaceful atom can develop electricity, which is about four times more cheaply produced in small hydroelectric power plants.
Nuclear power does not pollute the atmosphereharmful substances. The absence of emission saving treatment plant costs. Total 1 kg isotope substance replaces the use of 3-3.5 thousand. Tonnes of coal. To run smoothly for several years, middle-sized nuclear power plant require no more than 30 kg of fuel. In addition, the feedstock is obtained in the laboratory. Therefore, it is not necessary to develop a bulky mineral extraction and no reference to territorial waters. This is the opinion of supporters of nuclear energy.
Nuclear power can produce electricity is always, in any geographic location.
Their opponents give quite different figures,calling colossal waste disposal costs and the elimination of the consequences of different scale accidents. They also indicate a high initial cost of installation of such objects. However, today the nuclear power industry - the most affordable source of energy required to maintain the growing technical capacity in Europe.
Myth and reality: the low cost of alternative energy sources
often heard in today's society calls for thetransition to renewable natural sources of energy. There is an opinion about the low cost of wind energy: easy operation, fast payback installation, low depreciation, inexhaustible resource. A significant disadvantage of the wind turbine is a strong dependence on the movement of air masses and the impermanence of power output. Due to the instability of work, such plants can not be considered as producers of cheap energy.
Big future tipped scientists use solar energy. At the moment, it is the energy of the sun is the most affordable and stable of all the alternatives.
Scientists are working towards the accumulation of solar potential to eliminate the dependence on weather conditions.
In Japan, there was the first power plant using solar radiation. Perhaps the world is on the verge of opening a new eco-friendly and cheap energy source.
