FREE ECRE Critical Thinking and Analysis Questions and Answers
An energy consultant recommends a mix of solar and wind power for a rural area. What is the main reason for combining these two renewable sources?
Solar and wind energy complement each other, as solar is most effective during sunny days, while wind power can generate energy during cloudy or nighttime conditions.
A team designing a renewable energy system finds that the initial investment is high. How should they justify the project to stakeholders?
A detailed ROI analysis demonstrates the financial viability of the project, showing stakeholders how the initial costs will be offset by long-term savings and revenue generation.
A city plans to switch to renewable energy for 50% of its power needs within five years. Which factor should be prioritized to achieve this goal?
While other factors are important, the ability to integrate renewables into the existing energy grid is critical for achieving large-scale adoption without power instability.
A company evaluating energy efficiency notices that its energy bills are high despite using energy-efficient appliances. What could be the likely issue?
Hidden energy losses, such as air leaks or inefficient wiring, can negate the benefits of energy-efficient appliances, leading to high energy costs
A solar farm shows a significant drop in energy output during winter. What should be analyzed first to diagnose the issue?
Winter months generally have shorter sunlight hours and less intense sunlight, which directly affects solar energy production.
