75.2% of southern africa's energy come from highveld areas, where 5 of its 10 eskom power stations are the largest in the world. highveld areas are above sea level, making the oxygen level 20% less than the oxygen level in the coast. this results in an incomplete combustion of fossil fuels, and a severe nocturnal temperature inversion to occur; which results in smoke being trapped in the air 860 tons of so is produced from 3 of their main power stations (matla, duvha and arnot), “which exceeds the world health organisation’s (who) [exposure to particulate matter] standards of 180 mg.m-3 by 6 to 7 times during winter months (annegarn et al. 1996 a,b)”. this high concentration of air pollution surround the area making it very dangerous to one's health.

russia has a long history of small-scale wind energy use but has never developed large-scale commercial wind energy production. most of its current wind production is located in agricultural areas with low population densities where connection to the main energy grid is difficult. russia is estimated to have a total potential of 80,000 twh/yr for wind energy, 6,218 twh/yr of which is economically feasible. most of this potential is found in the southern steppes and the seacoasts of russia, although in many of these areas the population density is less than . this low population density means that there is little existing electricity infrastructure currently in place, which hinders development of these resources. in 2006, russia had a total installed wind capacity of 15 mw. current russian wind energy projects have a combined capacity of over 1,700 mw. the russian wind energy association predicts that if russia achieves its goal of having 4.5% of its energy come from renewable sources by 2020, the country will have a total wind capacity of 7 gw.
