About what type of energy is most available and expedient in the conditions of fight for eco-friendly space, scientists of many continents conduct long disputes. And today there are several versions in this respect.
Traditional electricity: opinions of pros and cons
Many experts consider the cheapest and advanced power source electricity produced on nuclear power plants to this day. Peaceful atom can develop the electric power which is approximately four times cheaper made on small hydroelectric power station.
The nuclear power plant does not pollute the atmosphere hazardous substances. The lack of emissions saves expenses on treatment facilities. Only 1 kg of isotope substance replaces use of 3-3.5 thousand tons of coal. To work smoothly within several years, the average size of the NPP no more than 30 kg of fuel will be required. Besides, initial raw materials are received in laboratory. Therefore, it is not necessary to develop bulky production of minerals and there is no territorial binding to reservoirs. Such is opinion of supporters of nuclear power.
The nuclear power plant can always make the electric power, at any geographical location.
Their opponents give completely different figures, calling enormous expenses on recycling and mitigation of consequences of various scale of accidents. Also they point to initially high cost of installation of such objects. Nevertheless, today nuclear power – the most available power source, necessary for maintenance of the growing technical potential in Europe.
Myth and reality: low cost of alternative energy sources
In modern society, appeals to transition to renewable natural power sources often sound. There is an opinion on the low cost of wind energy: easy operation, fast payback of installation, low depreciation, inexhaustibility of a resource. Essential minus of wind turbines is the strong dependence on the movement of air masses and inconstancy of the made power. Owing to instability of work such installations cannot be considered as producers of cheap energy. The big future is designated by scientists to use of solar power. At the moment energy of the sun is the most available and stable of all alternative options.
Scientists conduct the works directed to accumulation of solar potential to exclude dependence on weather conditions.
In Japan there was a first power plant using sunlight. Perhaps, the world is on the threshold of opening of a new eco-friendly and cheap power source.
