From the field
The same lessons come up again and again from people actually doing the job:
People think energy engineering is just power plants. It's the whole system — how energy is generated, moved across grids, stored, and used efficiently. I design parts of the system that power everything, and increasingly that means clean energy.

The energy transition made this one of the most exciting fields in engineering. Net zero needs the entire energy system rebuilt — renewables, storage, smart grids — and that's decades of work for energy engineers. The demand is enormous.

What keeps me here is the purpose. I'm an engineer like any other, but every project moves us toward a cleaner energy future. It's well paid, it's future-proof, and it genuinely matters for the planet. Few careers offer all three.
