The graph below gives information from a 2008 report about consumption of energy in the USA since 1980 with projections until 2030.
The line graphs illustrate data from a report in 2008 regarding
energy
consumption in the USA since 1980 with predictions until 2030.
Overall
, fossil fuels have shown an upward trend in use since the start of the period, with expectations for even more reliance on these fuel sources. Cleaner energy
sources have accounted for considerably less utilization with predictions for a similar trend.
Regarding fossil fuels such
as coal, natural gas, petrol and oil, they have seen steady rises in energy
usage since 1980. Petrol and oil started at 35 quadrillion
units
in 1980, then
fluctuated until 2000, at which point they rose steadily with a prediction of over 45 quadrillion
units
by 2030. Additionally
, coal followed a similar growing trend. It is predicted that it will have surpassed 30 quadrillion
units
by 2030. Natural gas usage is set to level off at around 24 quadrillion
units
from 2020 onwards.
In contrast
, cleaner energy
fuel sources all began the period at under 5 quadrillion
units
and showed declines in their use, with the exception of nuclear, which climbed slightly to 6 quadrillion
units
in 2005 with solar/wind expecting to see slight hikes. Hydropower is predicted to remain relatively unchanged until 2030.Submitted by yoqubjonovjamshidbek23 on
