“The conventional sources of energy need to be replaced due to their exhaustibility.” Justify the statement with suitable arguments.
Show Hint
• Burning fossil fuels causes pollution and climate change.
• Renewable energy supports sustainable development.
• Reducing dependence on imported fossil fuels strengthens energy security.
Solution and Explanation
• Conventional sources of energy include coal, petroleum and natural gas.
• These are non-renewable resources formed over millions of years.
• Their excessive use has created serious environmental and energy security concerns.
• Therefore, there is an increasing need to replace them with renewable energy sources.
Step 1: Limited Availability
Conventional energy resources are exhaustible and cannot be replenished within a short period. Continuous extraction will eventually deplete their reserves.
Step 2: Environmental Pollution
Burning fossil fuels releases carbon dioxide, sulphur dioxide and other harmful gases that cause air pollution, acid rain and global warming.
Step 3: Increasing Energy Demand
Rapid industrialisation, urbanisation and population growth have significantly increased energy consumption, putting pressure on conventional resources.
Step 4: Energy Security
India imports a large quantity of petroleum from other countries. Greater use of renewable energy can reduce import dependence and strengthen energy security.
Step 5: Sustainable Development
Renewable sources such as solar, wind and hydel energy are environmentally friendly and ensure long-term sustainable development. Answer: Conventional sources of energy need to be replaced because they are exhaustible, cause environmental pollution, increase greenhouse gas emissions and cannot meet the growing energy demand indefinitely. Renewable energy sources such as solar, wind, biomass and hydel power are sustainable, cleaner and help ensure long-term energy security.

Read the passage carefully and answer the questions that follow:
Hunting and Food Gathering
The earliest human beings depended on their immediate environment for their sustenance. They subsisted on: (a) animals which they hunted; and (b) the edible plants which they gathered from forests in the vicinity. Primitive societies depended on wild animals. People located in very cold and extremely hot climates survived on hunting. The people in the coastal areas still catch fish though fishing has experienced modernisation due to technological development. Many species, now have become extinct or endangered due to illegal hunting (poaching). The early hunters used primitive tools made of stones, twigs or arrows so the number of animals killed was limited. Gathering and hunting are the oldest economic activity known. These are carried out at different levels with different orientations. Gathering is practised in regions with harsh climatic conditions. It often involves primitive societies, who extract both plants and animals to satisfy their needs for food, shelter and clothing. This type of activity requires a small amount of capital investment and operates at very low levels of technology. The yield per person is very low and little or no surplus is produced.- Examine the role of climate, water availability, and soil fertility on the distribution of world population.
