Where would we be without electricity?

KttK008 Asked: Where would we be without electricity?

Imagine a world where electricity was never discovered, what would the world be like today? Forget TV, cable internet, AC etc. Combustion engines, automobiles motorcycles and chainsaws would have never been manufactured, skyscrapers impossible and the workplace would mean banging out horseshoes with a hammer and your home life would consist of growing crops, milking cows and plowing fields before hunkering down by the fire for the winter. If some global catastrophe put an EMP field over the planet and killed batteries, generators even solar power, could the world survive if something ever happened to electricity?

I think the simple example is:
When Light incidence to the photo cells(Viz: photo transistor or diode biased by this incidence of light), photo electric effect occurs—–>
Due to photo electriceffect,photo transistor or diode produces eclectic current(i.e electrical energy)
—–> This photo transistor/diode acts like a driver of the audio oscillatorand triggers the power audio oscillator——> then produces audio frequency of specific or variable frequency according to the design—-> this audio oscillator frequency/ies signal hooked (interfaced) to the matched loudspeaker——> Now we hear the sound which is a mechanical energy. I think this is one simple examplefor your question. Thank you. [You will find above:the conversion like this: Light energy--> Electrical energy ----> mechanical energy].
