Jobs By Energy Source

Here's a little chart I whipped up for the number of US jobs per unit energy for the major types of energy source*:


PJ = petajoule = 1015 joules (J)
EJ = exajoule = 1018 joules (J)
M = mega, B = billion, kWh = kilowatt-hour
pv = photovoltaic, h&c = heating and cooling

*Numbers in blue are data I looked up, numbers in black are calculated.

This isn't just for electricity, but all primary energy production. Of course, for solar and wind and coal it's almost all electricity, except for the occasional coal-powered vehicle. I did that calculation too; it's the last column in the chart.

There's a lot to quibble with here -- this is down and dirty. I'm not a professional analyst getting paid to do this perfectly. Most of concern to me is that I'm not sure "oil and gas extraction" includes any related management jobs, like in corporate headquarters. Same for coal. (And, for that matter, solar and wind.) It doesn't include the jobs in coal powered electricity plants (or solar plants). But the differences in jobs per energy are so large -- by one order of magnitude for wind, and two orders of magnitude for solar -- that one would have to do a whole lot of quibbling to make a difference in the conclusion that there are many more jobs in renewable energies than in fossil fuels, per unit of energy generated. (Why is this?)

And remember, despite the larger number of jobs, solar and wind power are now cheaper than coal in 3/4ths of the country.
