Abstract

Energy serves as the basis for any process in all sectors of the national economy, it is the main condition for creating material wealth, and improving the standards of living. Traditional energy sources include thermal power plants, nuclear power plants, and hydroelectric power plants. Humanity consumes a huge amount of energy 75% of all energy consumed is minerals (34% - oil, 25% - coal, 19% - natural gas). Constantly rising electricity tariffs are reason enough to think about all the possible ways to save money, since the share accounted for by lighting devices is quite large. Many people know about devices only that they
promise significant savings, but few can say that they know exact characteristics of each type, their difference from competitors.
