@MrRaulstrnad What was your first thought?
For most people it's about 5 (usually 3-8) because they don't go beyond the switch or socket - they think of a desk lamp or a room light.
A few engineers (mostly with an electrical background) go onto the power station, but even fewer (without prompting go back to the basic metals needed.
Since I have worked in manufacturing and more recently mining I just go with the metals and my basic list is.
Tungsten (filament)
Tin (bulb cap)
Copper (low voltage wiring)
Aluminum (for the cores of the HV transmission lines)
Iron (transformers, transmission towers & lines)
Zinc (for galvanizing exposed iron components)
Nickel, Manganese & Chromium (for the stainless that wraps around HV transmission lines)
Coal (to process the iron ore)
Sulphur (to make sulphuric acid to process the other ores except aluminum)
Soda Ash (to make caustic soda to process the aluminum)
So that's at least 10 (or more) mines with all the factories that make mining equipment - diggers, trucks, crushers, conveyors, screens, tanks, pipes,..............etc
Then there's the trains, trucks, & ships that take the raw mining materials of to the processing plants.
Then there's the processing plants for taking the raw mining materials and producing raw stock - iron, nickel, aluminum smelters.....,etc.
Then there's the factories that make all the things that go into building a power station.
Then there's the factories that make all the things that go into building a power grid
Then there's the factories that make all the things that go into building a house with wiring.
Then there's the factories that make all the things that go into building a light.
And does not include any of the other infrastructure or many other raw materials required so that 1 person can have a home and turn on that light.
It's at least 20,000 and may be well over 50,000.
