FAQs on Energy Resources Video Lecture - Geography Class 12 - Humanities/Arts

1. What are the different types of energy resources?
Ans. There are several types of energy resources, including fossil fuels (such as coal, oil, and natural gas), renewable energy sources (such as solar, wind, hydropower, and geothermal), and nuclear energy.
2. How do fossil fuels contribute to energy production?
Ans. Fossil fuels are burned to produce heat, which is then used to generate electricity or power engines. This process releases carbon dioxide and other greenhouse gases into the atmosphere, contributing to climate change.
3. What are the advantages of renewable energy sources?
Ans. Renewable energy sources have several advantages, including being sustainable, producing little to no greenhouse gas emissions, and reducing dependence on fossil fuels. They also offer long-term cost savings and promote energy independence.
4. How does nuclear energy work?
Ans. Nuclear energy is generated through a process called nuclear fission, in which the nucleus of an atom is split, releasing a large amount of energy. This energy is then used to generate electricity. Nuclear power plants do not emit greenhouse gases, but they do produce radioactive waste that needs careful management.
5. What are the challenges associated with transitioning to renewable energy sources?
Ans. The transition to renewable energy sources faces challenges such as initial high costs, intermittency (reliability of supply), and the need for infrastructure upgrades. Additionally, some communities may face job losses in traditional energy sectors. However, advancements in technology and supportive policies can help overcome these challenges.
