This data-file aggregates the labor intensity of different energy sources: wind, solar, oil, gas, coal and nuclear, based on data from the United States and from underlying projects.
Direct labor intensity tends to vary between 75-150 workers per TWH of useful energy. The gas industry is among the most efficient power sectors, providing 100 jobs per TWH of useful energy. Oil-fired transportation is less efficient at 135 workers per TWH, rising to 730 per TWH if you include service station staff.
Renewables have a jagged profile. A typical wind and solar project creates 250-500 jobs per TWH during the construction phase, but only just 20-30 during the operational phase. So in the short-run, jobs may be creatd by expanding renewables but in the long-run, they may be destroyed.
