hi buddies, this is an essay prepared for my IELTS test, please help correct it. Thanks a lot.^_^ The pie charts show the change of the quantity of electricity sources in Australia and France between 1980 and 2000. Between these years the total electricity production almost doubled, rising from 100 units to 170 in Australia, and from 90 to 180 units in France. In 1980, the use of coal accounted for the half of the total production, followed by natural gas, hydro power (each producing 20 units) and oil (only 10 units). While by 2000, the percentage of coal production rose to almost 75%, then came by hydro power (approximately 20%) and oil. By contrast, the major source of electricity production were coal and natural gas (each for 25 units respectively). The remaining 40 units were mainly produced from nuclear power and oil, with hydro power only contributing 5 units. However, these years had witnessed the growing in nuclear power that took up almost 75%, followed by oil (about 13%), while other sources were no longer significant.
