Is Iceland a very rich country?

Although it is a "frozen land", Iceland is a rich country, where people live a rich life. Its prosperity mainly depends on fishery, hydropower and geothermal resources. Fishery production is the pillar industry of Iceland's economy, and 70% to 80% of the national economic income depends on exporting fishery products. Water resources are also one of Iceland's advantages. Iceland has a lot of precipitation, steep terrain, fast-flowing rivers and a lot of water energy. If it is fully developed and utilized, it can generate more than 30 billion kWh of electricity every year, and now only about 10% has been developed. Iceland's geothermal energy reserves are greater than water energy. If all of them are used, it can generate more than 80 billion kWh of electricity every year, but now only about 7% is developed and utilized. It should be pointed out that hydropower and geothermal energy are clean energy and can be used permanently in the foreseeable future. Therefore, it has been envisaged to vigorously develop hydropower and geothermal energy in Iceland and transport them to Britain and continental Europe through submarine cables. At that time, Iceland will gain inexhaustible wealth.
