LEED AP Building Design and Construction (BD+C) Practice Exam

Which of the following systems is eligible for renewable energy production?

1. Solar thermal systems

2. Coal-based electrical systems

3. Natural gas turbines

4. Nuclear power plants

The correct answer is: Solar thermal systems

Solar thermal systems are indeed eligible for renewable energy production. These systems harness solar energy to generate heat, which can then be used for various applications, including electricity generation, heating water, and providing space heating. By converting sunlight to thermal energy, solar thermal systems contribute to reducing reliance on fossil fuels and lowering greenhouse gas emissions, aligning them with the principles of sustainability and renewable energy practices. In contrast, coal-based electrical systems, natural gas turbines, and nuclear power plants do not fall under the category of renewable energy. Coal is a fossil fuel that contributes significantly to carbon emissions and environmental degradation. Natural gas, while cleaner than coal, is still a fossil fuel that produces carbon dioxide when burned. Nuclear power, although it does not generate greenhouse gases during operation, is not classified as renewable energy due to the concerns surrounding nuclear waste disposal and the potential for catastrophic failures. These distinctions are essential for understanding renewable energy systems and their contributions to sustainable development.
