The pie charts below show units of electricity production by fuel source in Australia and France in 1980 and 2000.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The charts compare the sources of electricity in Australia and France in the years1980 and 2000. Between these years electricity production almost doubled , rising from 100 units to 170 in Australia , and from 90 to 180 units in France.
The pie charts below compare water usage in San Diego, California and the rest of the world.
The pie charts give information about the water used for residential, industrial and agricultural purposes in San Diego County, California, and the world as a whole.
It is noticeable that more water is consumed by homes than by industry or agriculture in the two American regions. By contrast, agriculture accounts for the vast majority of water used worldwide.
In San Diego County and California State, residential water consumption accounts for 60% and 39% of total water usage. By contrast, a mere 8% of the water used globally goes to homes. The opposite trend can be seen when we look at water consumption for agriculture. This accounts for a massive 69% of global water use, but only 17% and 28% of water usage in San Diego and California respectively.
Such dramatic differences are not seen when we compare the figures for industrial water use. The same proportion of water (23%) is used by industry in San Diego and worldwide, while the figure for California is 10% higher, at 33%.

In 1980 Australia used coal as the main electricity source(50 units) and the remainder was produced from natural gas , hydro power(each producing 20 units) and oil (which produced only 10 units). By 2000, coal had become the fuel for more than 75% of electricity produced and only hydro continued to be another significant source supplying approximately 20%.
In contrast, France used coal as a source for only 25 units of electricity in 1980, which was matched by natural gas. The remaining 40 units were produced largely from oil and nuclear power, with hydro contributing only 5 units. But by 2000 nuclear power , which was not used at all in Australia , had developed into the main source, producing almost 75% of electricity, at 126 units, while coal and oil together produced only 50 units. Other sources were no longer significant.
Overall, it is clear that by 2000 these two countries relied on different principal fuel sources: Australia relied on coal and France on nuclear power.
