MP Board · Class 8 · English Grammar · Unseen PassageRead the following unseen passage carefully and answer the questions that follow: "Energy is the driving force behind all modern human activities, industrial development, and technological progress. Traditionally, human civilization has relied heavily on fossil fuels such as coal, petroleum, and natural gas to meet its energy demands. However, fossil fuels are non-renewable natural resources that exist in limited quantities and take millions of years to form. Continuous and excessive burning of fossil fuels releases colossal amounts of greenhouse gases into the atmosphere, causing severe air pollution, acid rain, and global climate change. In contrast, solar energy is a powerful, clean, and inexhaustible source of renewable energy. India, being a tropical country, receives an abundant amount of sunlight throughout the year, making solar energy an ideal solution for its growing energy needs. Solar panels convert sunlight directly into electricity without emitting harmful pollutants or greenhouse gases. Utilizing solar energy reduces dependence on imported fossil fuels, cuts down electricity costs, and protects the global ecosystem. Shifting towards solar and other renewable energy sources like wind and hydro power is critical for achieving sustainable development and preserving the planet for future generations." Questions: Why is solar energy considered a better alternative to traditional fossil fuels? Mention the major disadvantages of excessive dependence on fossil fuels as described in the passage. Find words from the passage that mean: (i) Incapable of being depleted or used up completely (ii) Existing in extremely large amounts or quantities Give a suitable title for the passage and summarize its core moral message.

Detailed Answers to the Passage Questions

1. Why Solar Energy is a Better Alternative:\nSolar energy is considered vastly superior to conventional fossil fuels due to several significant reasons outlined in the passage:

• Clean and Eco-friendly: Unlike fossil fuels, solar power generation through solar panels produces electricity without emitting harmful air pollutants, smoke, or toxic greenhouse gases.
• Inexhaustible Resource: Sunlight is an infinite, renewable source of energy that will never run out, whereas fossil fuels like coal and petroleum exist in finite amounts and are rapidly depleting.
• Economic and Energy Security: For a tropical country like India, harnessing abundant sunlight reduces expensive fuel imports, decreases electricity bills, and promotes self-reliance in energy sector.

2. Disadvantages of Excessive Reliance on Fossil Fuels:\nContinuous and heavy dependence on fossil fuels brings serious economic and environmental hazards:

• Environmental Pollution: Burning coal, petrol, and diesel releases high levels of harmful carbon compounds causing urban smog, severe respiratory issues, and acid rain.
• Climate Change: Excessive carbon emissions contribute directly to global warming and global climate instability.
• Resource Depletion: Since fossil fuels take millions of years to form naturally, over-exploitation is rapidly exhausting these non-renewable resources.

3. Vocabulary / Word Meanings:

• (i) Incapable of being depleted or used up completely: Inexhaustible
• (ii) Existing in extremely large amounts: Colossal (or Abundant)

4. Suitable Title and Core Message:

• Suitable Title: Solar Energy: The Power of Sustainable Future (or Renewable Energy vs Fossil Fuels).
• Core Moral Message: The central lesson is that sustainable development requires an immediate shift from polluting, non-renewable energy sources toward clean, green, and renewable sources like solar power. Protecting the Earth's environment for future generations demands responsible energy choices today.
