Registered Environmental Manager (REM) Practice Exam

Which of the following is an example of an energy source?

1. Coal

2. Wind

3. Solar

4. Natural gas

The correct answer is: Solar

The selection of solar power as an example of an energy source highlights its role as a renewable and sustainable means of generating energy. Solar energy is harnessed from sunlight using various technologies, such as solar panels, which convert sunlight into electricity or heat. This form of energy is abundant and can be used in a variety of applications, from residential power generation to large-scale solar farms. While other options also represent legitimate energy sources, the unique characteristic of solar energy lies in its infinite availability and low environmental impact compared to fossil fuels. Solar energy contributes to reducing dependence on non-renewable resources, thus playing a critical role in promoting environmental sustainability and reducing greenhouse gas emissions. It's important to recognize that coal, wind, and natural gas are also significant energy sources with their specific uses and environmental implications. Coal is a fossil fuel that has been used for centuries but is associated with high carbon emissions. Wind energy is renewable and increasingly popular, but it relies on specific geographic and climatic conditions. Natural gas serves as a cleaner fossil fuel alternative but is still finite and produces emissions when burned. Each energy source has its strengths and challenges, but emphasizing solar energy showcases the shift towards cleaner and sustainable energy solutions.
