Electricity
Electricity is the life force of modern world. The use of electricity in daily life at all levels is too expensive to be enumerated. The electric., power has transformed human life into an amazing experience of convenience, luxury, comfort and incredible ease. A great power became the slave of a human finger’s push. Push to a button brings the light on and the same act sets hundreds of thousands of gadgets in action. It simply is a miracle, very real and more bountiful Than ginnie of the Alladin’s wonder lamp. The electricity revolutionized our houses, drawing rooms and kitchen with useful implements.
The array of entertainment aids powered by electricity really created a fancy world around us. The coming into the existence of a power like electricity that obeyed the command of the human finger’s touch inspired the inventions and innovations of a mind boggling range of electric implements. Infect, all the man made machines or gadgets wholly or partly run on electricity.
It created wonders of entertainment like cinema, radio, TV, VCD, DVD and other audio-video systems. The electricity helped man go to space, land on moon and harness natural powers and resources. The mining, construction, irrigation, transport, printing and other industrial activities are dependent on electric power. Even the computers won’t work any wonders without the electricity. Today, the progress of a society or a nation or economy is so dependent on electric power that all the power generating resources and options are being exploited or explored. Oil, coal, water, air, sun light, tidal waves and atomic phenomena are being used for power generation. The research on hydrogen as fuel and controlled fusion process are going on at feverish pitch.
The oil and coal are non-renewable resources. Hydel power has limitations as no new rivers can be created. Solar energy is yet costly to harness. The wind energy too has limitations. The tidal wave processes are yet at an experimental stages. And so are hydrogen and fusion ideas. Conventional atomic energy clearly is the best pollution free option but it entails the tricky problem of atomic waste disposal.

Answers
- The human life has become a wondrous experience of luxury, convenience, ease and comforts.
- The tip of a human finger controls electric power by pressing switches.
- The life comes to a standstill if power goes off in a modern city.
- The hydel power has limitations because no new rivers can be created by human endeavor. And only some places with suitable topographic setting allow dams on the existing rivers.
- The plus point of the nuclear power generation is it is totally pollution free. But the nuclear waste disposal is very tricky and hazardous.
