The line graph displays the data on fuel energy consumption, based on a 2008 report done in the USA. The figures were recorded in quadrillion units spanning the years 1980 to 2008, with a projection of usage through 2030.
To highlight, among the six fuel types presented, petrol and oil rank first in energy usage and will continue
this
trend into the future. Linking Words
Also
, the data show that hydropower is the least preferred type, trailing significantly.
With about 35q of the report results, petrol and oil led the list. Linking Words
This
trend is projected to increase and reach around 50q in 2030. Linking Words
Then
, natural gas recorded at 20q in 1980, showed marked fluctuation and was forecast to plateau in 2015, extending to 2030, setting at 20q. Coal came in Linking Words
third,
5q lower compared to natural gas. Linking Words
However
, it surpassed the latter in 1990 and is set to reach about 30q in the future. Notably, three types of fuel were around 3q in the beginning, which were nuclear, solar/wind, and hydropower. With relatively small increments and decrements noted, it is speculated that these renewable energies will stay within the brackets of 3-10q by 2030.Linking Words
