▶ Your Answer :
The
line graph depicts the energy consumption by fuel types in the USA from 1980 to
2008 with the projection of 2030.
Petrol
and Oil was the predominated energy consumption and this will continue with
this trend will continue in the future. Nuclear, solar/wind and Hydropower energy sources
have represented the smallest energy consumption and this will be the same for
the projections.
Petrol
and oil recorded at 35 quadrillion units (35 q) of energy consumption to be consumed by all the
USA citizens in 1980. Despite some periodic fluctuations throughout, the
overall trend was raising to approximately 40 q in 2008. This trend is set to
continue with a projected value of nearly 50 q in 2030. In 1980, natural gas and
coal followed next as it initiated at 20 q and 15 q respectively. Despite the
small periodic fluctuation for the coal and natural gas consumption, the
consumption for coal overtook the consumption for natural gas from 1985 to
2000. After that, the consumption for both energies leveled off and is
expected to be set at 30 q for coal and 25 q for natural gas in 2030.
Nuclear,
Solar/wind and hydropower all represented at 4 q in 1980 and fluctuated until
2008. Nuclear consumption distinctively leveled off since 1990 and continued
to grow to reach at over 5 q in 2008, which is predicted to be the same by 2030.
Concurrently, Solar/wind and Hydropower had some several periodic fluctuations
until 2008 and are speculated to be reached at about 5 q and around 2 q,
respectively. <(what about for 2030?)
