This is an essay I practised. Can you help me find out the inappropriate usages and bad grammar? Throughout the history of development of science and technology and the improving people’s living standard, the situation that people cannot spend a life without electricity become more and more certain. In order to guarantee sustainable power supply, large-scale exploitation of natural resources like coal and oil has been seen as a primary means since the eighteenth century. In recent years, however, as the continuing decline of fuel source, almost the entire world is committed to develop newer and clearer energy, such as hydro, wind, and nuclear energy. The four charts illustrate units of electricity by five different energy resources in Australia and France in the year 1980 and 2000. In Australia electricity production by coal made up the biggest part of the total in both 1980 and 2000, the units of which shot up from 50 to 130, significantly. The second main fuel source is hydro power, by which the electricity production climbed from 20 units in 1980 to 36 in 2000, partly benefiting from its unique geographical position. Unlike the two energy resources, the use of oil and natural gas met a dramatic decrease, began with 10 and 20 units of electricity in 1980 respectively, and then both fell to 2 units by the year 2000. An obvious difference between France and Australia is the use of nuclear power in electricity sector. There was a boost in electricity production by nuclear in France between 1980 and 2000, reached an eight times high in 2000. The use of oil also made a slight increase by 5 units. However, the other three fuel source showed an opposite tendency. In 1980, the units of electricity production by coal and natural gas witnessed a same number 25, and the use of coal leveled off at 25 units in 2000, while the other energy resource slipped to only 2 units. The original low number of units of electricity by hydro power at 5 dropped another 3 units in 2000. Each country has its preference for the fuel source used in electricity production, by the limitation of geographical location, type of natural resources, and the development of science and technology. But, compared the total electricity production in 1980 with that in 2000 in both Australia and France, it is undeniable that the number edged up and will still go up on projection, even in terms of the entire world.
