Question

Quizplus · Accepted Answer

The negatives involve both the hazardous waste created and the energy needed to complete the process, which lower the EROEI (Energy Returned on Energy Invested). Option A is incorrect because the product of coal cleaning is not a liquid or gaseous fuel. Option B is incorrect because it focuses only on the energy needed and ignores the hazardous waste. Option D is incorrect because it only concerns the inefficiency of the process, while there are other negatives as well. Option E is incorrect because it emphasizes the amount of water needed, which is not a significant negative factor in comparison to hazardous waste and energy requirements.
