Agriculture means farming of crops or the rearing of animals, either for their own use or for commercial purposes. Rural area means a place away from the city, opposite of urban areas, with little buildings and most likely have a smaller population.

Therefore, the only activity that is almost practiced exclusively in rural area is agriculture. Urban areas don't have much space and well environment for agriculture activities.

Agriculture activities can be energy consuming as some may require different machines to help with farming processes such as harvesting or irrigation.
