Volkswind / Frequently Asked Questions /
Wind energy is the conversion of the kinetic energy from the wind into electrical energy using wind turbines. This form of energy is renewable because wind is an inexhaustible resource.
A wind turbine works by using the wind to turn its blades. This rotational motion is transferred via a shaft to a generator, which converts the mechanical energy into electrical energy.
There are mainly two types of wind turbines:
The average lifespan of a wind turbine is about 20 to 25 years. After this period, components can be replaced or the entire turbine can be upgraded.
The electricity generation depends on the size of the turbine and wind conditions. Modern turbines can produce between 2 and 10 megawatts (MW) of power. A wind farm can thus supply power to several thousand households.
The main components are:
Wind energy has relatively low environmental impacts compared to fossil fuels. The main concerns are landscape changes and impacts on bird and bat populations. However, these can be minimized with careful planning and technology.
Yes, the cost of wind energy has significantly decreased over the past decades. Wind energy is now one of the cheapest forms of electricity generation and often operates without subsidies.
Wind energy can significantly contribute to energy security by reducing reliance on fossil fuels and providing a domestic energy source.
Yes, it is possible to install small wind turbines on private property. The feasibility depends on local wind conditions and specific regulations.
Location selection is based on various factors, including:
At the end of their life, most parts of wind turbines are recycled or reused. Rotor blades, often made of composite materials, present a recycling challenge, but advancements are being made in recycling technology.
Innovations include the development of more efficient rotor blades, floating offshore wind turbines, and improved storage systems for wind energy.
The future of wind energy is promising. With increasing demand for renewable energy and technological advancements, the share of wind energy in global energy production is expected to continue to grow.
These FAQs provide a comprehensive overview of wind energy, its functioning, economic and ecological aspects, and future developments.
