Every figure below is a median annual wage from BLS OEWS, May 2024 data — the most recent state/national release as of this writing. Medians, not means: half the workers in each trade earn more, half less. No trade here requires a four-year degree.
| Trade | Median Annual Wage | Growth 2024–34 |
|---|---|---|
| Electrical Lineman | $92,560 | 7% |
| Automation/Mechatronics Tech* | $73,900* | — |
| Industrial Maintenance | $63,510 | 13% |
| Plumber | $62,970 | 4% |
| Wind Turbine Technician | $62,580 | 49.9% |
| Electrician | $62,350 | 9% |
| Diesel Mechanic | $60,640 | — |
| HVAC Technician | $59,810 | 8% |
| CNC Machinist* | $58,750* | — |
| Solar Installer / Tech | $51,860 | 42% |

What Actually Separates the Top of the Table
- Voltage and height. Linework tops the list by a wide margin — the trade combines the highest voltage exposure, the most demanding physical entry bar, and one of the narrowest apprenticeship doors in the network (~10,700 openings/yr vs. electrical's ~81,000). Scarcity plus danger plus infrastructure demand adds up.
- Fewer people can do the work. Automation/mechatronics and industrial maintenance sit near the top because the skill floor (PLC logic, controls troubleshooting, precision diagnostics) is genuinely harder to reach than entry-level trade work.
- Growth ≠ current pay. Solar and wind post the fastest growth rates in the entire network — 42% and 49.9% respectively — but currently sit lower on median pay because both trades are young and heavily weighted toward entry-level installation work. That's a forecast, not a floor.
The trades at the top of this table aren't the ones with the easiest entry. They're the ones with the smallest pool of people who can actually do the work.
What This Table Doesn't Capture
Two honest caveats. First, union total compensation: published wage surveys count base pay only, not employer pension and health-fund contributions — which in union-heavy trades (linework, plumbing, electrical) can add several dollars an hour in real value the median doesn't show (full explanation). Second, state variance dwarfs trade variance in some cases — the gap between the highest- and lowest-paying state for a single trade can be nearly 2:1, larger than the gap between many trades on this table (state-by-state comparison).
The Honest Read
Pick by fit first, pay second — every trade on this list clears a livable median with no tuition bill. But if pay is the deciding variable among trades you'd genuinely do, linework, industrial maintenance, and automation currently sit at the top; solar and wind are the ones to watch as their growth curves mature into wage curves.
