Total energy production in the US has risen for the sixth consecutive year.

New figures from the Energy Information Administration (EIA) reveal energy production reached a record 89 quadrillion British thermal units (Btu) – equivalent to 91% of total usage.

Liquid fuels production drove the increase, with an 8% rise for crude oil and a 9% increase for natural gas plant liquids. Natural gas production also rose 5% to a record high level of 79 billion cubic feet per day last year.

These gains more than offset a 10% decline in coal production, the ‘Monthly Energy Review’ states.

The US saw “little change” in production from nuclear power and renewable energy last year.

However it saw shifts in the sources of electricity generation from renewable fuels as declines in hydroelectric production were mostly offset by increases in wind and solar generation, the EIA adds.

The nation also saw a 2% reduction in carbon emissions last year as a result of an increase in the use of natural gas for power generation, which largely replaced coal.
