Electricity is our basic needs. Without electricity we cannot do anything of our life. Have we ever stopped to think how electric power comes from water? We have seen rocks shattered to pieces and carried away by rivers. Water can cut stones and make holes into them. This strength of water produces electricity. as water is available in abundance a large amount of energy can be produced from it. We may have seen traditional 'ghatta' in villages. Water is poured from a higher place to run the 'ghatta'. Asimilar process is applied in big water-power projects. Water is stored in dams or tanks and its poured into the wheels within the turbines. We should visit a water power project and see for ourselves and learn in detail how it works.
Electricity is used for various purposes. We use electricity for light, cooking, operating heater, refrigerator, washing machine, irons and other electric gadgets. The credit of fast growing communication goes to electricity. It runs internet, television, telephone and so on. At a large scale, electricity is used to run big machines in industries. We may have soon rice or oil mill run on electricity. Similar is the process with printing press sawing factory and other industries. However, water is not only source of electricity. Electricity can be produced from solar energy, vapour energy, bio-gas energy, steam power and diesel as well. Therefore where hydro-electricity is not available, other sources can be used for generating energy.
