Geography Notes Chapter 9 Energy Resources Class 6 Maharashtra Board

Notes For All Chapters – Geography Class 6
1. What are Energy Resources?

• Energy resources are natural sources that provide power for different activities.
• We need energy for transport, cooking, industries, and daily life activities.

2. Types of Energy Resources

Energy resources are divided into two types:

1. Conventional Energy Resources (Traditional, can get exhausted)

• Examples: Wood, coal, petroleum, natural gas, hydel power.

2. Non-Conventional Energy Resources (New, renewable, and eco-friendly)

• Examples: Solar energy, wind energy, bio-gas, tidal energy, geothermal energy.

3. Conventional Energy Resources

(a) Firewood

• Used in villages for cooking.
• Causes smoke and deforestation.

(b) Coal

• Found in mines and used for trains, industries, and power plants.
• Causes pollution when burned.

(c) Mineral Oil (Petroleum)

• Used in vehicles, factories, and power plants.
• Refined into petrol, diesel, and kerosene.

(d) Natural Gas

• Found underground and used for cooking (LPG) and vehicles (CNG).
• Burns cleanly without pollution.

(e) Hydel Power (Electricity from Water)

• Produced by dams on rivers.
• Cheap and renewable, but affects river ecosystems.

4. Non-Conventional Energy Resources

(a) Solar Energy (Sun’s Energy)

• Used for cooking, heating water, and electricity.
• Unlimited and pollution-free.

(b) Wind Energy

• Windmills generate electricity from wind.
• Eco-friendly and renewable.

(c) Bio-Gas

• Made from cow dung and plant waste.
• Used for cooking and electricity.

(d) Tidal Energy (Sea Waves Energy)

• Produced from sea waves.
• Used for electricity generation.

(e) Geo-Thermal Energy (Heat from Earth’s Surface)

• Found near hot water springs.
• Used for electricity and heating.

5. Importance of Saving Energy

• Reduces pollution and protects nature.
• Saves natural resources for the future.
• Helps in sustainable development.

6. Conservation of Energy

• Switch off lights and fans when not needed.
• Use public transport to save fuel.
• Use solar, wind, and bio-gas energy to reduce pollution.
