 Short Answer Questions (Anyone) 

Write any three advantages and disadvantages of Hydel power. (3 Marks)

Advantages:

1. Hydroelectricity is a non-polluting form of energy.
2. One-fourth of the world’s electricity is produced by hydropower. 
3. Generate Hydro electricity by constructing Dam

Disadvantages:

1. Setting up a hydel power plant can be very expensive
2. Local community should be displaced for the construction of Dam
3. Due to the reservoirs, large areas of lands get flooded, and this destroys the natural habitats of wild animals.

Write any three advantages and disadvantages of Wind energy (3 Marks) 

Advantages:

1. Low-cost, safe and clean source of energy.
2. Wind energy is an inexhaustible and non-polluting form of energy. 
3. Wind mills are used to produce electricity.

Disadvantages:

1. It creates noise pollution and can harm birds.
2. Setting up a windmill is costly. 
3. It disturbs radio and TV signals.

 Long Answer Questions (Anyone)   

Explain the difference between conventional and non-conventional source of energy. (5 Marks) 

How do the names of different textiles tell us about their histories?(5 Marks) 

1. People have been using hot springs and geysers for bathing, cooking and heating, for centuries. 
2. Today, geothermal energy is being used for broader applications, like generating electricity. 
3. Geothermal plants are inexpensive to set up and their scale of operation can be altered according to the size of projects. 
4. However, geothermal plants are generally located far away from cities and, hence, it can be expensive to transport energy through long distances.
