"Britain forms the greater part of the British Isles, which lie off the north-west coast of mainland Europe. Its area is 242,400 square km (93,600 sq. miles). Its weather is changeable, but there are few extremes of temperature. Britain is a major world producer of oil, natural gas and coal. Since 1980 it has been self-sufficient in energy in net terms. With over 67 million people in 2022, Britain ranks sixteenth in the world in term of population. Britain consists of England, Wales, Scotland, and Northern Ireland. And its four component lands have separate traditions and cultures. Over the centuries immigrants and political refugees from many other European countries have added their own customs to these."
