IntroductionIn the 21st century almost all devices run on electricity. Electricity makes people's activities easier and more comfortable. Furthermore, it plays an important role in the development of medicine, science, education, transportation and other areas of human life. However, electricity production is becoming increasingly problematic because most electricity is produced from natural resources, which are neither infinite nor renewable. This means that mineral reserves may one day run out and, as a result, there will be a risk of a possible energy crisis. This situation stimulates humanity to switch to renewable energy system. Countries around the world are promoting sustainable energy policies, particularly to reduce the greenhouse effect that contributes to serious problems such as global warming and acid rain (Energy Information Administration (EIA) 2010). The problem of finding alternative energy sources is also popular in Kazakhstan. Kazakhstan is extremely abundant in natural resources, especially fossil fuels, which are used primarily as energy sources to generate electricity (CIA Factbook 2011). To be more precise, almost 60% of the 4.6 billion kilowatts of energy produced in Kazakhstan in 2008 came from coal, almost 35% from natural gas and oil, 3% of the electricity was created by hydroelectric power plants and nuclear power, and the remaining energy was imported from Kyrgyzstan and Uzbekistan (EIA 2010). It appears that electricity production in Kazakhstan is mainly based on coal and other minerals. Therefore it is important to find an alternative energy source in Kazakhstan to reduce dependence on coal and avoid energy crises and other negative effects resulting from the use of non-renewable energy. Because the territory of Kazakhstan is… the focus of paper… and gas because it is a traditional and time-tested solution (ibid). Furthermore, no less important factor is the high price of the devices needed to provide solar energy and the fact that it pays for itself in 30-40 years. To be more precise, almost 80% of the cost of the CSP system is related to its construction, on the contrary, this figure for fuel plants represents 20% of the total cost (Environmental and Energy Study Institute (EESI) Factsheet 2009) . On the other hand, unlike oil or coal, solar energy is free, and therefore CSP operations cost 30% less than fossil fuel power plants (ibid). Overall, despite the possible problems that can be corrected with the improvement of the CSP supply system, it can be suggested that the exploitation of concentrated solar energy will facilitate Kazakhstan to produce more electricity by reducing its dependence on coal and succeed in providing renewable energy.
