Damage to wind turbine blades can be induced by lightning, fatigue loads, accumulation of icing on the blade surfaces and the exposure of blades to airborne particulates, causing so-called leading edge erosion. . Abstract: A review of the root causes and mechanisms of damage and failure to wind turbine blades is presented in this paper. For operators, understanding the most common blade issues and implementing effective prevention strategies is essential to ensure consistent energy. . Rotor blades are critical components of wind turbines, enduring various weather conditions and high speeds. It's crucial to monitor their condition closely to ensure optimal performance and safety. Unlike enclosed mechanical systems, blades must endure a wide variety of external stressors, which increases their failure rate.

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. In a wind power plant, the kinetic energy of the flowing air mass is transformed into mechanical energy of the blades of the rotor. This page offers a text version of the interactive animation: How a Wind Turbine Works. How does windmill electricity work. .

What is the energy access problem in Mali?
Mali faces a critical energy access challenge. The national power access rate was 50% in 2019 (compared to 36.11% in 2015). The problem is particularly acute in rural areas with 21.12% access rate in 2019 (compared to 15.75% in 2015).
Why is energy du Mali struggling with load shedding?
Power generation is limited (Annex A.17), forcing Energie du Mali (EDM, the power utility) to have recourse to frequent load shedding. EDM's difficulties stem from the discrepancy between the average price (CFAF96 per KWh) and the power production cost (CFAF130 per kWh) in 2019.
