Actually he did not invent the lightbulb, he only improved on it making it practical and inexpensive.

His real impact on electrical technology was to invent the infrastructure (e.g. large generators, distribution grid, electric usage meters, fuse boxes, light switches, light sockets) needed to support those lightbulbs so that people could depend on them working when needed.

The creation and maintenance of this infrastructure for the first time was of far greater significance than the invention of lightbulbs or his perfection of lightbulbs.
