50 GK Questions on Renewable and Non-Renewable Energy Sources with Answers | MCQ Quiz for Class 7+

Energy is fundamental to our daily lives, powering everything from home appliances to industries. Sources of energy fall into two broad categories: renewable (like solar, wind, and hydro) which can be replenished naturally, and non-renewable (like coal, oil, and natural gas) which are finite and take millions of years to form. Understanding their characteristics, advantages, and limitations is essential for sustainable development. Test your knowledge with this 50-question MCQ quiz designed for Class 7 and above on renewable and non-renewable energy sources!
