South Africa - South Africa - Diamonds, gold, and imperialist intervention (1870–1902): South Africa experienced a transformation between 1870, when the diamond rush to Kimberley began, and 1902, when the South African War ended. Midway between these dates, in 1886, the world's largest goldfields were discovered on the Witwatersrand. As the predominantly agrarian societies of European ...
Although South Africa could hold the world's fifth largest shale gas reserves, there was limited interest in developing these resources until recently. 11 However, recurrent power shortages combined with environmental concerns stemming from an overdependence on a single energy source—coal (which provides over 70 percent of all South Africa ...
South Africa is the fifth largest hard coal producer in the world and a major exporter of coal into the world market. It is also heavily dependent on coal for power generation and is aiming to rapidly expand its coal-based generation capacity. It is also a major exporter of power to utilities in neighboring countries and directly to some major individual customers in Mozambique and Namibia.

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit ...
That's cool. But this slavery thing in South Africa is just a little too bitter for our social-democratic taste buds. Besides, you're not giving American workers their 'fair share' of the exploitation! To take up the line that the coal imports from South Africa rob miners of their jobs dovetails with this view.
