Arrange the sentences into the correct order.
Put the sentences in the correct order:
- Researchers are therefore experimenting with cheaper renewable energy sources, hoping to make vertical farms competitive with conventional agriculture within the next decade.
- The approach remains expensive, however, since the electricity needed to power lighting and climate systems can outweigh the savings gained from reduced land and water use.
- This precise control lets a vertical farm produce several harvests per year in a fraction of the space that traditional agriculture would require for the same yield.
- Within these structures, LED lighting tuned to specific wavelengths replaces sunlight, allowing growers to control exactly how much energy each plant receives at every stage of growth.
- Vertical farming addresses the shrinking availability of arable land by growing crops in stacked layers inside climate-controlled buildings rather than on open fields.
