Each "quad" is
one quadrillion BTUs,
used here to compare
the last five years
of energy use
in the United States.
Each quad has
the energy
contained in
185 million
barrels of
crude oil.
Overall energy
use in the U.S.
actually decreased
to 100.2 quads in 2019,
similar to a decrease
last seen in 2015
The percentage
of fossil fuels
used in the 2019
energy mix
decreased
by 0.2 points
from last year
to make up 80.0%
of the total.
This effectively
negates the small
rise of fossil fuel
usage in 2018:
Since 2015, natural gas use
has grown from 29% to 32%
of the U.S. energy mix
— while coal’s role
in the mix has dropped
by 4.7%.
In 2015 solar added
0.532 quads of energy
to the mix, while in 2019
it accounted for 1.04 quads
— a 95% increase.
Residential, commercial, and
industrial sectors are all
increasing their use of energy,
while the transportation sector
is seeing a drop in energy use,
thanks to more fuel efficient cars,
EVs, public transport, and
