Abstract:
The modern world is a big consumer of energy. From personal comfort, to travel, jobs and industry we consume fuels. Fossil fuels are exhausting resources and, at the same time, their combustion has irreversible effects on the environment, such as the greenhouse effect or the release of pollutants harmful to our health.
Unlike fossil fuels, renewable energy sources such as solar energy, wind energy, ocean energy or bioenergy are inexhaustible resources and mainly have no impact on the environment. This paper discusses wind turbines, such as devices for transforming wind energy into electricity. Wind energy and wind resources in our country are analyzed here. Also, the physical phenomena that appear at the intersection between the wind and a turbine are presented. An in-depth comparison between the horizontal-axis and the vertical-axis wind turbine is the main topic of this paper. Finally, there is an analysis of the research carried out to increase the reliability and reduce the manufacturing and maintenance costs of the components of a wind turbine with a horizontal axis. Additional work will be done to build and test a horizontal axis turbine in the laboratory.
