**Major exceptions that DON'T use steam:**
- **Solar photovoltaic panels** - Direct conversion of sunlight to electricity (no steam!)
- **Wind turbines** - Mechanical energy from wind directly drives generators
- **Hydroelectric dams** - Water pressure drives turbines directly (no heating)
- **Diesel/gasoline generators** - Internal combustion engines
- **Fuel cells** - Chemical reactions produce electricity directly
