Read the following passage and circle the letter A, B, C or D to indicate the correct answer to each of the questions from 39-45
Wind power is a renewable energy source that harnesses the natural movement of air to generate electricity. Large wind turbines, typically placed in areas with strong and consistent winds, convert kinetic energy into mechanical power, which is then transformed into electrical energy through a generator. Unlike fossil fuels, wind power does not produce harmful emissions, making it an environmentally friendly alternative for electricity production.
The efficiency of wind power depends on factors such as wind speed, turbine design, and location. Offshore wind farms tend to be more productive than onshore ones because wind speeds are generally higher over water. However, setting up offshore wind farms requires more advanced technology and higher costs compared to land-based installations. Despite these challenges, many countries are investing in wind power to reduce their reliance on fossil fuels and combat climate change.
Wind energy has some drawbacks, including noise pollution and its impact on bird populations. Additionally, because wind is an intermittent energy source, it cannot always provide a constant supply of electricity without storage solutions like batteries. Nevertheless, ongoing technological advancements aim to improve wind power efficiency and address these challenges, making it an increasingly important component of the global energy mix.
