Worked Solution & Example Answer:A photograph of a wind turbine is shown below - NSC Agricultural Technology - Question 3 - 2017 - Paper 1
Step 1
Name THREE aspects to consider when selecting a wind turbine to generate power for an electric fence on a game farm.
Answer
-
Surrounding Environment/Site Selection/Topography: Evaluating the terrain and wind conditions is crucial, as these factors can significantly influence the wind turbine's efficiency.
-
Cost Effectiveness: It is important to assess the overall costs associated with purchasing and installing the turbine, and how this compares to potential energy savings over time.
-
Maintenance: Consideration should be given to the expected maintenance frequency and costs, as well as the availability of service providers.
Step 2
Describe FOUR advantages of using a wind turbine to generate electrical energy.
Answer
-
No Fuel Costs: Wind energy is free, meaning there are no ongoing fuel costs, which can lead to significant savings.
-
Low Maintenance Costs: Wind turbines generally have low maintenance requirements, which reduces long-term operational costs.
-
Environmental Benefits: Wind power generates electricity without emitting pollutants, contributing to a cleaner environment and reducing reliance on fossil fuels.
-
Renewable Energy Source: Wind is a renewable resource, ensuring a sustainable supply of energy without depleting natural resources.
