Modern way of living increasingly requires us to use all our resources in a rational way. Electrical energy is not an exception to this principle. The very concept of sustainable development is largely based on this idea.
We are witnessing an increase in electricity consumption. Energy consumption has been increased throughout the world. Development of technology leads to the production of new appliances used in households and industry. Rational consumption is the most prevailing way of how to save electricity. Otherwise, we have to put in force the idea that we consume only as much as we require.
