I am at an IEEE meeting this weekend and had a long discussion about renewable energy systems and safety. That prompted this week's question.

Have you worked with renewable energy systems? What types?
Select all that apply.

None
Solar
Wind
Geothermal
Biomas
Hydro
Tidal/Ocean
Other - Specify

I worked specifically on a solar inverter, but the inverter was supposed to do wind and tidal as well. It also was able to use battery power as well.

Yes, with several types: Photovoltaics and Energy Storage: Lithium Battery, Flow Battery, Flywheel, Thermal. All this from residential to utility-scale installations.

Not sure if this counts as renewable, but I worked on a downhill conveyor that regenerated power by a VFD.

I would think a regenerative downhill belt conveyor would not necessarily be a renewable energy source. We see this sort of thing in EV regenerative braking as well. I believe this would mainly fall under the heading of system efficiency. Plus the electrical safety aspects should be well covered by VFD safety standard, I should think. ~Doug
