In today's world, the problems of energy conservation and ecology are becoming more appropriate. The use of energy technologies helps not only to reduce the cost of electricity, but also to reduce the harmful effects that one has on nature in the process of one's life, taking into account its increasing needs. One begins to appreciate the environmental natural materials, clean water, clean air. People began to build wooden houses and equip them with wood furniture, buy peeled bottled water in stores, use systems at home and cars that clean and moisten the air. One began to think about what air breathes, what water he drinks and how in the future it affects his health and life expectancy.
Environmental pollution is the negative changes in the biological, physical, chemical characteristics of the atmosphere, water, soil, adversely affecting human life, animals and plants that emit the planet's resources as a whole. The main sources of pollution are thermal power plants, petrochemical industrial enterprises, iron and unarmed metallurgies, production of building materials and chemical industry, cars and air transport. Only power plants cause great damage to the environment. Even the usual electric lamps that we use the contamination of the middle of our habitat, this applies to daylight lamps containing lead mercury and phosphorus. The use of LED lighting lamps significantly reduces the harmful effects on nature, the consumption of electricity when using such lamps decreases up to ten times, and the harmful radiation during operation is minimized, as well as minimal release of harmful substances in the environment and with subsequent disposal.
The most effective way to reduce harmful emissions into the atmosphere, such as carbon dioxide, is to improve production methods, transfer and subsequent energy discharge. Each year, the number of equivalent greenhouse gas emissions is about 44 billion tonnes. The introduction of new high environmental technologies will reduce the number of these emissions to 25 billion. So, heat power plants that use combined steam and gas units have an efficiency of up to 60%, while the efficiency of traditional TPPs average is 46%. For this reason, the work of power plants with combined installations is more efficient and also differs in the smaller number of harmful emissions. A significant contribution to the reduction of carbon dioxide emissions can use environmental technologies in construction, more special the use of environmental building materials.
Modern air -conditioning systems, heating and heating water, increased thermal insulation can reduce the amount of CO2 equivalent by about 2 billion tonnes, and the use of LED lamps saving energy will save significantly electricity and less clogs the environment. A person, with the help of the most technical progress in the field of energy, effectively uses renewable environmental energy sources, properly uses waste, making them biogas, electricity or other derivatives, is able to minimize the harmful effects on nature. When saving the planet, it is important to realize the threat of inaction, to evaluate the opportunities provided to us technical progress for its salvation. It is necessary to take decisive steps in this direction now.
