The most appropriate solution of oil depletion problemis to switch to renewable energy sources. The global demand for renewableenergy sources is constantly growing.
Almost all developed countries now are developingand implementing programs related to alternative energy. Furthermore, today theusage of renewable energy has become an important and obligatory direction forthe development of the energy sector of the future. Moreover, Kazakhstan hasall the necessary resources in this regard.
It seems that given the electricitydeficit in the country, especially in the southern regions, the wider use ofalternative sources becomes particularly important. Most countries all over theworld almost entirely depend on fossil fuels like oil, coal and gas. Unconventionalsources of energy can be the energy of the sun, wind, ocean tides, and thewarmth of the earth’s depths. Its attractiveness is caused by inexhaustibleresources, independence from the conjuncture of prices in the world energymarkets and, importantly, ecological purity.
Orloff (2017) claims that “alternative orrenewable energy sources show significant promise in helping to reduce theamount of toxins that are by-products of energy use and help preserve many ofthe natural resources that we currently use as sources of energy” (para 1). The greatest advantage of thissolution is that using renewable energy is ecologically clean and it will nothave harmful effects to the nature. It might have low greenhouse production. Forexample, while extracting fossil fuels, the air and water pollution can have abad influence on the world’s population, which might lead to problems withbreathing, cancer, or even to heart attacks. “Wind and solar energy requireessentially no water to operate and thus do not pollute water resources orstrain supply by competing with agriculture, drinking water systems, or otherimportant water needs” (“Benefits of RenewableEnergy Use”, 2013, para 10).
Anotherbenefit is that they are renewable, which means they do not deplete and willnot run out. In addition, these sources are free for use. The greatest disadvantageis dependence from climatic changes, as the availability of this energy alsodepends on it. As explains Orloff (2017), wind power is not always regular, forcontinuous power generation constant wind is needed, and therefore if the wind’sspeed declines, the capacity of generated electricity become lower. Similarly, ifthe sun is not shining the solar power does not produce the energy and theamount of it is limited.
Another disadvantage is cost of equipment that we needto use for renewable energy sources, for example, the cost of solar panels.According to Kitaev (2015), their price ranges from $ 3 to $ 5 per watt ofpower and this is without battery accessories, charge controllers, converters.The same is true for wind energy, as even though wind is free, the cost of windturbines is high.
