Do you know how to conserve energy? If so, attempt this conservation of energy quiz questions and answers and test how well do you know. We conserve energy to reduce the consumption of energy to cut costs and preserve it for a longer period of time. We can achieve energy conservation by using fewer energy services and switching off the appliances when not in use. Take the quiz below and test your understanding of this topic. All the best, buddy!
