Tonga's economy is characterized by a large nonmonetary sector and a heavy dependence on remittances from the half of the country's population that lives abroad, chiefly in Australia, New Zealand, and the United States. Much of the monetary sector of the economy is dominated, if not owned, by the royal family and nobles. This is particularly true of the telecommunications and satellite services. Much of small business, particularly retailing on Tongatapu, is now dominated by recent Chinese immigrants who arrived under a cash-for-passports scheme that ended in 1998. The manufacturing sector consists of handicrafts and a few other very smallscale industries, all of which contribute only about 3% of GDP. Commercial business activities also are inconspicuous and, to a large extent, are dominated by the same large trading companies found throughout the South Pacific. In September 1974, the country's first commercial trading bank, the Bank of Tonga, opened.
Top Sectors in Tonga
Energy in Tonga
the Tongan government committed to a target of 70% renewable energy by 2030.In July 2012 Tonga Power opened Tonga's first solar photovoltaic generator, the 1.32 MW Maama Mai Solar Farm on Tongatapu.This was followed by a 6MW solar farm spread across three sites on Tongatapu.A pair of 13 MW / 24 MWh grid batteries began operating on the main island in 2022. An Outer Islands Renewable Energy Project is installing solar / battery systems on nine smaller islands, and upgrading the electrical grids on Eua and Vavau.
Agriculture in Tonga
The Agriculture of the Tongan Archipelago is largely based on the farming of yams, squash, and root crops. Agriculture consists of 16-29.9% of Tonga's GDP, 34% of its labour force, and about 50% of its exports. Since the 1980s, Tonga's agricultural exports expanded to include vanilla, watermelons, sugar, and legumes.With the expansion of the archipelago's population, climate change, and competitive markets, Tonga has trouble keeping up with competitive demand.
