The given pie charts compare the sources of various types of energy consumed in a specific country in 2000 and 2010.
Overall, the consumption of petrol experienced a significant decrease from 29% to 20% while solar energy consumption approximately doubled. Moreover, the consumption of coal and gas accounted for the highest share of energy use in the given years.
In 2000, coal and gas consumption made up almost two-thirds of total energy use at 30% and 29.5%, respectively. Similarly, the use of petrol accounted for just under 30 percent. Solar energy had the lowest share, at 6.5%, while other sources accounted for a small proportion.
In 2010, while petrol consumption fell to one-fifth, the use of other energy sources grew dramatically. Coal consumption reached 31%, and gas usage increased slightly to 30%. Solar energy usage rate experienced a significant rise, approximately doubling to one-tenth.
