Key Points

  • Fossil fuels are not renewable sources of energy. They are formed over millions of years from the remains of dead plants and animals.
  • Burning fossil fuels releases sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) into the atmosphere, which can cause acid rain.
  • Acid rain has harmful effects on plants, aquatic animals, and infrastructure, and it can lead to soil degradation.
  • Fossil fuels include coal, oil, and natural gas, which are primary sources of energy for many countries worldwide.
  • Transitioning to renewable energy sources like solar, wind, and hydro power is essential for sustainable development.

Additional Information

  • Renewable Energy: Energy from sources that are naturally replenishing such as solar, wind, hydro, and geothermal.
  • Greenhouse Gases: Gases like carbon dioxide (CO₂) and methane (CH₄) that trap heat in the atmosphere, contributing to global warming.
  • Sulfur Dioxide (SO₂): A gas produced by volcanic activity and industrial processes, especially the burning of coal and oil at power plants and refineries.
  • Nitrogen Oxides (NOₓ): Gases produced from vehicle emissions, industrial processes, and the combustion of fossil fuels.
  • Climate Change: Long-term shifts and alterations in temperature and weather patterns, primarily caused by human activities, especially fossil fuel combustion.
