We all know that natural resources are being depleted. But it's not near as recently thought to be exhausted (coal reserves, for example, will suffice for many hundreds of years old) - first and foremost concerned about deleterious effects of non-renewable energy resources in the human environment. The main drawback of combustion in thermal power plants of fossil fuels is pollution emissions. Even the thermal power plants using modern high-technology, such as burning coal in a fluidized or circulating fluidized bed, from an environmental point of view is far from perfect. In addition, cause irreparable damage to the mining, processing, transportation fuels and absolutely useless gas flaring and oil. We must not forget that in addition to natural sources to atmospheric oxygen is burned; planetary reserves can come to the end, too. Hydroelectric power stations that carry light to people in the house while their share in world energy is small (on average 15%) and cause huge damage to nature. The overlap of the rivers by dams, the use of vast areas of land under the reservoir has led to serious environmental violations. Well aware of the limitations and nuclear energy: storing and processing of radioactive waste, the danger of radioactive contamination in case of accidents. Among the most attractive alternative is solar energy, environmentally friendly only because billions of years, comes to Earth and Earth processes all become accustomed to it. This light is the closest to us. The flow of solar energy people just have to take control and make maximum use, thus maintaining unchanged the unique Earth's climate. To enhance the flow of solar energy, it is necessary to collect it from a large area with hubs and store for future use in batteries. While this can be done in the so-called low power, heat and light homes and small businesses must be supplied with energy. The solar power plants are able to provide light and heat - that is why they are considered to be more convenient than any other distributed power tower and boiler. Mirrors, turning track the movement of the sun and direct its rays on a boiler. Lately solar houses began growing very rapidly. In the simplest and most common form most of the energy needs of the house are provided by sunlight and heat, thereby decreasing the cost of other energy sources by 40-60%. Solar house equipped with an efficient thermal plant can fully satisfy the needs of its inhabitants in the warmth and light even without using other energy sources.
