In today's world, the problems of energy conservation and ecology are becoming more and more relevant. The use of energy -saving technologies helps not only to reduce electricity costs, but also to reduce the harmful effects that a person has on nature in the process of his life, taking into account his increasingly growing needs. A person begins to appreciate environmentally friendly 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 in houses and cars that clean and moisturize the air. A man began to think about what air he breathes, what water he drinks, and how in the future it affects his health and life expectancy.
Energy saving and ecology
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 exude the resources of the planet as a whole. The main sources of pollution are thermal power plants, petrochemical industry enterprises, ferrous and non -ferrous metallurgy, production of building materials and chemical industries, cars and air transport. Only power plants cause great damage to the environment. Even the usual electric lamps that we use pollute the environment of our habitat, this applies to daylight lamps containing lead mercury and phosphor. The use of LED lamps for lighting significantly reduces the harmful effects on nature, the consumption of electricity when using such lamps decreases to ten times, and harmful radiation during operation is minimized, also minimally release 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 disposal of energy. Every year, the number of greenhouse gas emissions equivalent CO2 is about 44 billion tons. The introduction of new highly environmentally friendly technologies will reduce the number of these emissions to 25 billion. So, thermal power plants, which use combined steam and gas turbine units, have an efficiency of up to 60%, while the efficiency of traditional TPPs on average is 46%. To this, the work of power plants with combined installations is more effective, and also differs in a smaller number of harmful emissions. A significant contribution to the reduction of carbon dioxide emissions can make the use of environmentally friendly technologies in construction, in particular, the use of environmentally friendly building materials.
Modern air conditioning systems, heating and heating water, increased thermal insulation can reduce the amount of equivalent of CO2 by about 2 billion tons, and the use of LED energy -saving lamps will significantly save electricity and much less clog the environment. A person with the help of the latest achievements of technical progress in the field of energy conservation, effectively using renewable environmentally friendly energy sources, properly utilizing waste, transforming them into biogas, electricity or other derivatives, is able to minimize harmful effects on nature. In the rescue of the planet, it is important to realize the threat of inaction, to evaluate the possibilities provided to us with technical progress for its salvation. It is necessary to take decisive steps in this direction now.
