How will you make small power plants in your home? briefly explain it

Answer:
Not so long ago, alchemists dreamed of turning cheap and ugly metals into valuable ones like gold. Power plants (also called power stations) pull off a similar trick, converting lumps of coal and drops of oil into zaps of electric current that can cook your dinner or charge your phone. If it weren't for power plants, I wouldn't be writing these words now—and you wouldn't be reading them. In fact, most of the things we do every day and much of the stuff we use owes a hidden debt of gratitude to these gigantic energy factories, which turn "fossil fuels" (coal, natural gas, and oil) into electric power.
This energy-alchemy is a pretty amazing trick—and quite a recent one too, since the very first practical power station was built in only 1882 (by Thomas Edison). Yet amazement is often the last thing we feel when we think about generating electricity at the start of the 21st century. In an age when caring for the environment is (quite rightly) more important than ever, it's fashionable to sneer at power plants as evil, dirty places pumping pollution into our air, land, and water. One day, we might be able to make all our electricity in a completely clean and green way. Until then, power plants are vital for keeping our schools, hospitals, homes, and offices light, warm, and buzzing with life; modern life would be impossible without them. How do they work?
