Twenty-five percent of Taiwan's land is arable. Crops are rice, wheat, corn, sorghum, sweet potatoes, bamboo shoots, mushrooms, sugarcane, betel nut, peanuts, fruit, tea and tobacco. Livestock includes pigs, chickens, ducks and dairy cattle. Taiwan has small resources of petroleum, coal and natural gas which can meet around five percent of its energy needs. Nuclear and hydroelectric power contribute, but much oil and coal has to be imported.
Manufacturing is important to the economy.
The main heavy industries are petrochemicals, plastics and metals. Taiwan is a leading supplier of electronic goods especially hardware and software for the computer industry and also a major world producer of synthetic fibres. There is a rapidly growing motor vehicle industry. Other industries include food processing, fisheries and the production of wood and bamboo products. Tourists, especially from Japan and the USA, are important sources of foreign currency.
