I’d assume this is true over any sufficiently long time horizon.
I’d guess it’s like 20 years for a lotta stuff? i.e. short enough the average Lemming would benefit in their lifetime

More like a year. A wind turbine, depending on size, position etc, generates the amount of power used in it’s construction within 2.5 - 11 months. Over it’s life cycle it generates about 40x the energy you put in.
