FAQs on Conventional Sources Of Energy Video Lecture - Geography for Class 8
| 1. What are conventional sources of energy? |  |
Ans. Conventional sources of energy refer to the traditional sources that have been widely used for centuries to generate power. These sources include fossil fuels like coal, oil, and natural gas, as well as nuclear energy.
| 2. Why are conventional sources of energy important? | |
Ans. Conventional sources of energy are important because they provide a significant amount of the world's energy needs. They are relatively easy to extract and have been used extensively for power generation. However, their extensive use has led to environmental concerns due to their contribution to air pollution and climate change.
| 3. How do fossil fuels contribute to air pollution? | |
Ans. Fossil fuels, such as coal, oil, and natural gas, release harmful pollutants into the air when burned for energy production. These pollutants include sulfur dioxide, nitrogen oxides, carbon dioxide, and particulate matter. These emissions contribute to air pollution, smog formation, and can have detrimental effects on human health and the environment.
| 4. What are the environmental impacts of conventional sources of energy? | |
Ans. Conventional sources of energy have several environmental impacts. Burning fossil fuels releases greenhouse gases, leading to global warming and climate change. Extraction activities can damage ecosystems and habitats, such as coal mining destroying landscapes and oil spills polluting water bodies. Additionally, the disposal of nuclear waste poses long-term risks to the environment.
| 5. Are there any alternatives to conventional sources of energy? | |
Ans. Yes, there are several alternatives to conventional sources of energy. Renewable energy sources like solar power, wind power, hydropower, and geothermal energy are gaining popularity due to their lower environmental impact. These sources are replenishable and do not produce greenhouse gas emissions during operation. Investing in these renewable sources can help reduce our dependence on conventional energy and mitigate environmental concerns.
