Problematic issues of operation and utilization of air turbine blades

Abstract

The gradual increase in the number of electricity producers predicts the further development of alternative energy. Renewable energy is an environmentally friendly, inexhaustible source of energy, which makes it possible to reduce the burden on the resource base and reduce overall resource consumption. In addition, the use of rene-wable energy sources contributes to the sustainable development of cities, which, thanks to solar, wind, biogas installations, can provide themselves with electricity, thereby reducing their costs and resource dependence. The population can independently produce electricity and control its distribution, while also minimizing losses during transmission over long distances. Wind energy is one of the promising areas in the field of renewable energy sources. The article examines the problematic issues of using wind energy and disposing of wind turbine blades, which is the main goal of the work. It is well known that certain conditions are required to generate electricity from wind turbines. As research has shown, the most promising places for the production of electrical energy are considered to be coastal sea areas, where powerful air currents are formed during the year. Research into the problem of disposal shows that this issue is very relevant and outweighs all the advantages of wind energy. The typical lifespan of wind turbine blades is about 20-25 years. Among the modern recycling methods, the following options are being considered to solve this problem ‒ using fiberglass as noise barriers, for example, on high-ways and pressing of blades, for example, into fibreboards for use as pallets in the construction industry, fencing and railway sleepers, etc. To achieve the goal, the authors of the article applied the methods of analytical review of scientist’s and specialist’s works of scientists and experts, systematic analysis of theoretical materials and practical recommendations in world practice regarding the operation and disposal of wind turbine elements. It was found that scientific analysis is mainly focused on researching the optimal and highest-quality disposal methods, which requires future, global research
