An electric railway receives electricity from two generating systems.
The table shows the electricity generated for the railway during one week.
| Generating system | Electricity generated in MWh |
|---|---|
| Water released from a reservoir flows downhill and turns a generator | 360 |
| Natural gas from an underground gas field is burned to generate electricity | 240 |
