Energy consumption is essentially flat (+1% to 2040). Energy use in power generation grows by 10%. Among final sectors, growth in buildings (+5%) and non-combusted uses (+35%) is offset by declines in transport (-10%).
Energy consumed in power generation increases by 0.4% p.a. from 2016-40, half the growth rate of 1990-2016.
Improvements in vehicle efficiency cause energy use in transport to fall by 0.4% p.a., after growing by 1.0% p.a. over 1990-2016.
By fuel, growth in renewables including biofuels (+220%) and natural gas (+30%) is offset by declines in coal (-69%), oil (-18%) and nuclear power (-28%).
Natural gas becomes the leading fuel, accounting for 40% of US energy consumption, up from 32% today. Renewables (17% in 2040) also gain market share while coal and oil lose significant share (accounting for 5% and 30% of energy use, respectively, in 2040).
Renewables (including biofuels) see the largest growth increment of any fuel growing by 5% p.a..
Renewables surpass coal as the second-largest source of power generation (by fuel input) around 2030.
Domestic energy production increases by 39%; growth in natural gas (+65%), oil (+55%) and renewables (+220%) more than offset declines in coal (-48%) and nuclear power (-28%).
The US remains the largest producer of liquid fuels and natural gas. Oil production increases by?7 Mb/d over the Outlook to reach 21 Mb/d by 2040.
Natural gas production increases by 46 Bcf/d to 118 Bcf/d.
Energy intensity (the amount of energy required per unit of GDP) declines by 35% 2016-40, similar to the decline seen over 1990-2016 (-38%) and to the global decline to 2040 (-37%).
Flat energy consumption combined with a shift in the fuel mix (more renewables and gas; less coal and oil) drives a decline in CO2?emissions from energy use of 21% by 2040.
