What agricultural product requires the least amount of energy


The least energy efficient foods are animal-based products, particularly beef, lamb and goat. This is because beef requires up to 20 times more resources and emits 20 times more greenhouse gas emission than plant-based protein sources. Poultry and pork use slightly less energy but are still far bigger emitters than plant products.
