A hospital complex requires 6.0 MW of electrical power continuously. During an emergency, the power demand can rise to 10.0 MW. The electricity supply must meet this demand even after a long dry spell.
The table gives information about three energy resources available near the hospital.
| Energy resource | Electrical power available |
|---|---|
| Geothermal | 6.5 MW at all times |
| Hydro-electricity | 0 MW after a long dry spell |
| Bio-fuel | Up to 4.0 MW from fuel stored at the power station |
Which resource should provide the continuous power and which resource should provide the additional power during an emergency?
