| Judicious use of Energy |
|
| In order to live and enable ourselves to do everyday work we need energy. The prosperity of a country depends upon the availability of energy. Huge amount of electrical energy is used to run the air conditioners, cold storage and other domestic appliances. A large share of energy is needed for transportation. There has been increase in the world's population year after year. |
| |
| The demand for energy is increasing. The natural sources of energy like coal and petroleum products are fast depleting. Unless the increase in the production of energy is in the same proportion as its increasing consumption, there is bound to be a worldwide shortage of energy leading to a global energy crisis. |
| |
| To overcome this energy crisis the development and use of alternative sources of energy is imperative. It is said that energy saved is energy produced. The growing demand of energy can be met by making a judicious use of available resources of energy. |
| |
| In our homes conservation of fuel begins at the electric light switch. By thinking whether or not an electric light is needed or by switching it off when not required the fuel resources of the world can be conserved. Modern homes are built to conserve fuel by using building materials and methods that insulate the house. In the colder parts of the world insulation helps to keep heat in and save fuel. |
| |
| Relying more heavily on renewable resources and recycling of wastes into energy can help to conserve energy. Replacement of low efficient machinery can lead to energy saving. Use of solar energy can be encouraged. For the world to solve its energy problems great changes in our ways of living and working will have to take place. |
