MP Board · Class 8 · English Grammar · Unseen PassageRead the following unseen passage carefully and answer the questions that follow: "Solar energy has emerged as one of the most promising and clean renewable energy sources of the modern era. As non-renewable fossil fuels such as coal, petroleum, and natural gas deplete rapidly and contribute significantly to global warming and atmospheric pollution, the world is shifting toward sustainable alternatives. Solar power is harnessed directly from sunlight using photovoltaic cells, converting light into clean electricity without emitting harmful greenhouse gases. India, blessed with abundant sunshine throughout the year, has immense potential to lead the global solar revolution. Rooftop solar panels, solar water heaters, solar street lights, and large-scale solar farms are transforming energy generation across rural and urban regions. Utilizing solar energy reduces dependence on fossil fuels, lowers electricity bills, and minimizes environmental degradation. Embracing solar power is not just an economical choice, but a moral obligation to protect our planet for future generations." Questions: Why is solar energy considered superior to traditional fossil fuels? Detail the practical applications of solar energy mentioned in the passage and their benefits to society. Find words from the passage that mean: (i) Capable of being sustained or continued without depleting natural resources (ii) Existing in large quantities; plentiful Give a suitable title for the passage and summarize its core moral message.

Step-by-Step Solution

Answers to the Unseen Passage

1. Superiority of Solar Energy over Fossil Fuels:

  • Clean and Renewable: Solar energy is derived directly from sunlight, which is infinite and clean, whereas fossil fuels (coal, petroleum) are finite and non-renewable.
  • Environmental Impact: Fossil fuels release massive amounts of carbon dioxide and harmful pollutants during combustion, causing climate change and air pollution. In contrast, solar energy generation produces zero greenhouse emissions, protecting ecological health.

2. Practical Applications and Social Benefits:

  • Key Applications: The passage highlights rooftop solar panels, solar water heaters, solar streetlights, and commercial solar farms.
  • Benefits to Society:
    • Reduces heavy reliance on depleting fossil fuels.
    • Significantly lowers domestic and industrial electricity costs.
    • Provides reliable power supply to rural and urban communities.
    • Minimizes carbon footprints and environmental degradation.

3. Vocabulary / Word Meanings:

  • (i) Capable of being sustained without depleting natural resources: Sustainable
  • (ii) Existing in large quantities; plentiful: Abundant

4. Suitable Title and Core Message:

  • Suitable Title: "Solar Energy: The Bright Future of Green Power" or "Harnessing Renewable Solar Power"
  • Core Message: The passage urges humanity to transition from polluting fossil fuels to sustainable solar power. Switching to green energy is crucial for environmental preservation, economic stability, and fulfilling our duty to hand over a clean, livable Earth to future generations.
