▶ Your Answer :
The line graph illustrates the figures for spending energy, in the USA over the period of five decades starting from the year of 1980 and gives a prediction to 2030. At first glance, petrol and oil was the major sources of fuel, rising from about 35 quadrillion units in 1980 to 42 quadrillion in 2014. Despite some fluctuation between 1980 and 1995, there was a steady increase, which is expected to continue and reach around 50 quadrillion in 2030. Consumption of energy from natural gas and coal followed a similar pattern over the period. From 20 quadrillion and 15 quadrillion respectively in 1980, the figures for both have fluctuated for after the following 35 years. However, coal consumption is predicted to rise to more than 30 quadrillion in 2030, whereas after 2014, natural gas spending is forecast to level off at around 25 quadrillion.
In 1980, energy from solar/wind, nuclear, and hydropower was the least-used, with only under 5 quadrillion. Since 2005, the use of hydropower has fallen back to the 1980 figure and it is expected to remain approximately constant through 2030, while the others are predicted to rise gradually after 2025.
