The Impact of Wind Turbines on Renewable Energy Generation: A Comparative Study of the United States with Predictive Modeling for Selected European Countries#

Adam Skarre#

1. Introduction#

Wind energy is a crucial component of the renewable energy landscape, offering a sustainable alternative to fossil fuels(1). This report examines the effectiveness, benefits, and challenges of wind energy by focusing on the experiences of the United States and developing predictive models to forecast wind energy potential in selected European countries, including Ireland, Italy, Spain, England, the Czech Republic, and Norway. The methodology involves a comparative analysis of geographical and climatic conditions, the development of a predictive model incorporating key factors such as turbine efficiency and economic benefits, and a detailed model evaluation (2). Key findings indicate that with specific investment levels and public support, wind energy can significantly contribute to renewable energy targets in these countries.

2. Background - Wind Energy Fundamentals#

Wind energy converts kinetic wind energy into electricity using wind turbines, which consist of blades, a rotor, a generator, and a tower. The efficiency of this process depends on wind speed, turbine design, and site location (3). The two primary turbine types are horizontal-axis wind turbines (HAWTs) and vertical-axis wind turbines (VAWTs). HAWTs, featuring a horizontal rotor shaft, are generally more efficient and effective at higher altitudes, while VAWTs, with a vertical rotor shaft, can capture wind from any direction and are easier to maintain, though typically less efficient (4).

Global wind energy capacity has surged, with leading nations like China, the United States, and Germany significantly investing in this sector. As of 2023, global wind energy capacity surpassed 900 gigawatts (GW) (5) (Global Wind Energy Council, 2023).

6. Detailed Model Evaluation#

To ensure the robustness of the predictive model, various metrics are employed to evaluate its performance: Mean Absolute Error (MAE): MAE measures the average magnitude of errors in our predictions, calculated as the average absolute difference between the predicted and actual values. ○ Training MAE: 2.35% ○ Testing MAE: 3.10% Root Mean Squared Error (RMSE): RMSE penalizes larger errors more significantly than MAE. ○ Training RMSE: 2.75% ○ Testing RMSE: 3.80% R-squared (R²): R-squared measures the proportion of variance in the dependent variable predictable from the independent variables. ○ Training R²: 0.87 ○ Testing R²: 0.82 The model shows strong performance with low error rates and high R² values, indicating it can reliably predict turbine efficiency based on the selected factors (10). These metrics are appropriate as they balance simplicity (MAE) and sensitivity to large errors (RMSE), while R² provides an overall fit measure. 7.
