Review Questions

• How does turbulence influence the efficiency of wind turbines in energy production?
  • Turbulence influences the efficiency of wind turbines by causing fluctuations in wind speed and direction, which can lead to inconsistent power output. When turbulence is high, it can result in lower overall energy conversion rates, as turbines may not operate optimally under rapidly changing conditions. Properly accounting for turbulence during turbine placement and design is essential to enhance their performance and maximize energy generation.
• Discuss the relationship between turbulence and solar irradiance variability in solar power systems.
  • Turbulence affects solar irradiance variability by causing rapid changes in sunlight intensity due to factors like cloud movement and atmospheric disturbances. This variability can lead to significant fluctuations in energy production from solar panels, making it challenging to predict total energy output accurately. Understanding how turbulence impacts solar irradiance helps in improving system designs and implementing better energy storage solutions to balance supply and demand.
