With increase in population, our needs have increased. Today the world is facing a problem of energy crisis. We must conserve energy. Which one of the following statements does not show an energy conservation approach?
A. Switch off the lights, fans, television and other application when not in use
B. One should use individual vehicle instead of public transport system
C. Make use of pressure cooker
D. use of bicycle while going to school

Hint: Energy saving is the attempt made to decrease the absorption of energy by using a minimum of an energy utilizing systems. We can save energy by reducing the combustion of fuel at home or by using private vehicles.

Complete Answer:
To answer this question, first, we need to know about the energy crisis. An energy crisis is any significant bottleneck in the supply of energy resources to an economy. In literature, it often refers to one of the energy sources utilized at a specific time and place; in specific to those which provide national electricity networks or those utilized as fuel in Industrial improvement and increase in population have led to flow in the global demand for energy in recent years.

Now, let us find the solution from the option.
- There are a number of new technologies out there that make lighting controls that much more interesting, and they help to conserve more energy and cash in the long utilization. Switch off the lights, fans, television and other applications when not in any utilization, in this way we can conserve lots of energy.
- We can save energy by using public transport systems, not by using individual vehicles which can increase pollution and cause energy crisis.
- Using a pressure cooker is also effective to save fuel energy because it takes less time to cook food.
- Using a bicycle also reduces loss of fuel energy because we do not need any fuel to ride a bicycle.

Thus, the correct option is B. i.e. One should use individual vehicle instead of public transport systems.

Note: The energy crisis involves the world's demands on the finite natural resources that are utilized to power the industrial system are decreased as the demand increases. These natural resources are in restricted supplement. Whilst they are found in nature easily, it can require thousands of years to refill the storages.
