Trends in the Use of Three Energy Sources Imagine a line graph showing the usage of three energy sources from 1980 to 2030: Petrol: Steady and continuous increase (highest point). Coal: Fluctuation followed by a slow increase. Natural Gas: Lowest point in 1980, but projected to catch up with coal by 2030.

The line chart illustrates the trends of energy usage figures for petrol, coal, and natural gas over the period from 1980 to 2030. Overall, it is evident that three types of energy showed completely different trends. Whereas petrol experienced steady growth throughout the period, the other two energies showed fluctuating or lower-level patterns. In terms […]
