AEP Renewable Energy & Sustainability 1 — Questions and Answers
Question 1: Which renewable energy source is the most widely used for electricity generation worldwide?
- Wind
- Solar
- Hydropower (Correct answer)
- Geothermal
Correct answer: Hydropower
Hydropower is the largest renewable electricity source globally, utilizing flowing water to generate energy efficiently and sustainably.
Question 2: What is a major benefit of solar power for electricity generation?
- It provides constant energy output
- It requires minimal land use
- It generates electricity without emissions (Correct answer)
- It does not require sunlight
Correct answer: It generates electricity without emissions
Solar power produces electricity without greenhouse gas emissions, making it a clean and sustainable energy source.
Question 3: Which factor is a challenge in integrating wind energy into the power grid?
- High fuel costs
- Wind variability and intermittency (Correct answer)
- Excessive greenhouse gas emissions
- Limited turbine efficiency
Correct answer: Wind variability and intermittency
Wind energy is variable and depends on wind availability, requiring energy storage or backup sources to maintain grid reliability.
Question 4: How do energy storage systems support renewable energy sustainability?
- They increase fossil fuel dependency
- They store excess renewable energy (Correct answer)
- They eliminate the need for power plants
- They reduce the efficiency of solar panels
Correct answer: They store excess renewable energy
Energy storage systems, such as batteries, store excess energy from renewables for use when demand is high or generation is low.
Question 5: What is the primary goal of sustainable energy practices?
- Increase short-term energy production
- Maximize fossil fuel use
- Reduce environmental impact and resource depletion (Correct answer)
- Minimize investment in renewable energy
Correct answer: Reduce environmental impact and resource depletion
Sustainable energy practices focus on reducing environmental impact, ensuring long-term energy availability, and minimizing resource depletion.
Question 6: Which technology helps improve the efficiency of solar panels?
- Fixed mounting
- Tracking systems (Correct answer)
- Opaque panel coating
- Decreasing panel size
Correct answer: Tracking systems
Tracking systems allow solar panels to follow the sun’s movement, increasing their efficiency by maximizing sunlight exposure throughout the day.
