Carbon-capture equipment retrofitted onto a coal plant traps most of the carbon dioxide the plant emits. But running the equipment consumes a large share of the plant's electricity, so the plant must burn extra coal to produce the same power for customers — and burning that extra coal releases more carbon dioxide.
Which of the following can be most properly inferred from the statements above?
- Retrofitting carbon capture onto a coal plant achieves no reduction in emissions whatsoever.
- The carbon dioxide a retrofitted plant ultimately keeps out of the air is less than the amount its capture equipment traps.
- Carbon capture equipment fails to trap most of the carbon dioxide a coal plant emits.
- Coal plants should be shut down rather than retrofitted with carbon capture.
- Running the capture equipment increases the amount of electricity the plant delivers to customers.
