The pie charts depict the data about the quantity of electricity obtained out of six sources in Gareline over a twenty-year period, 1970 to 1990. Overall, it is clear that hydropower constituted most of the city energy from 1970 to 1980, while geothermal turned out to be the most popular type of energy resource in the last ten years of 20th century. It is noticeable that a two-third of power was derived from hydro and geothermal, which accounted for 45% and 22% respectively. In contrast, energy from gas and other sources was the least, at just 1, 2 and 1, 4 percentage in turn. Besides that, nuclear energy was not applied in that time. In the next decade, there was a thirty-one- percentage increase in hydropower, compared with a significant decline of 14% in the amount of energy gained from geothermal. In 1990, the proportion of power from geothermal got the advantage over that for hydropower, whereas the nuclear power registered a gradual growth of around 16%.
