Energy that is produced from the heat of the earth’s interior is called Geothermal energy.
The word geothermal originated from the Greek word geo, which means earth, and therme which means hot or heat. Since heat is continuously produced inside the earth, geothermal energy is therefore a renewable energy source.
South Africa is a country located at the southern tip of Africa. It has had a rich colonial history since the seventeenth century. In 1652, the Dutch came and founded a colony on the Cape.
After a century and a half of Dutch colonization, the Cape Colony was taken over by the United Kingdom. As a result, a large number of Dutch-speaking settlers, known as Boers, migrated inland with the Great Trek and founded several Boer states, of which the South African Republic and the Orange Free State were ultimately the most important. These republics were conquered by the British in 1902 in the Second Boer War and united together with the Cape Colony and Natal to form South Africa in 1910.
In the 20th century, South Africa was overshadowed by apartheid, a system of racial segregation that systematically disadvantaged the non-white population. Apartheid was abolished in 1990 and Nelson Mandela was elected South Africa's first black president in 1994.
South Africa is a country with diverse population groups and eleven official languages. The country is a parliamentary republic with three capitals and is one of the most developed countries in the continent, but poverty and crime rates remain high.
