A food-processing plant needs 5400 GJ of energy each year to heat water.
An engineering survey estimates the energy that three possible installations could supply each year.
| Energy resource used by the installation | Energy supplied each year in GJ |
|---|---|
| the Sun | 6000 |
| bio-fuel made from vegetable waste produced on site | 5000 |
| wind | 8000 |
The plant will use one installation. The water must be heated without generating electricity first.
Explain which installation the plant should use. Refer to all three installations in your answer.
