I think the most influential invention in the last 100 years is electricity. Because first reason, every day, every person use it. It is very important. If it isn't work, most peole can't do their work. Secondly, we need light at night. There is no light except sun and light bulb. At night, there is no sun. So night-workers must need electricity.
