How did invention of the electric light bulb change the environment?

Answer 1

You can see without a fire, or burning candles, oil lamps and lanterns, which can be dangerous left unattended. Also no need to wait for daylight to do all the work that we wish to do. We can work indoors in bad weather, even on small detailed tasks, and homes can be built with smaller/fewer windows to conserve energy. We can make plans to complete jobs, and they don't depend on daylight hours, or sunny weather to complete them, especially fine detailed work that requires clear sight. People can work all hours of the day and night, keeping hospital, or medical services, and police, or security services available to those who need it. One's life and work in general don't revolve around the time of day, and what the weather, or season may provide in the way of illumination.
