Americans Opting for Renewables

Report Shows Americans Used More Energy in 2013 than in 2012

LIVERMORE, Calif. — Americans used more renewable, fossil, and nuclear energy in 2013, according to the most recent data released by Lawrence Livermore National Laboratory.

Each year, the laboratory releases energy flow charts that illustrate the nation’s consumption and use of energy. Overall, Americans used 2.3 quadrillion thermal units more in 2013 than the previous year.

The laboratory also has released a companion chart illustrating the nation’s energy-related carbon dioxide emissions. Americans’ carbon dioxide emissions increased to 5,390 million metric tons, the first annual increase since 2010.

Wind energy continued to grow strongly, increasing 18 percent from 1.36 quadrillion Btu, or quads, in 2012 to 1.6 quads in 2013. New wind farms continue to come online with bigger, more efficient turbines. Most new wind turbines can generate 2-2.5 MW of power.

Natural gas prices rose slightly in 2013, reversing some of the recent shift from coal to gas in the electricity production sector. Although this did cause carbon dioxide emissions to increase in 2013, the power industry is building a lot of natural gas plants, said A.J. Simon, group leader for energy at Lawrence Livermore National Laboratory. “Gas plants are cheaper than coal plants. Natural gas is going to be a winner into the foreseeable future.”

Overall, natural gas use increased by 0.6 quads. Losses in the electricity sector were more than offset by greater gas use in the residential, commercial, and industrial sectors. “2013 was a cold winter,” Simon said. “We expect to see continued high gas consumption in 2014, due to another tough winter on the East Coast.”

Nuclear energy use was greater in 2013 than in 2012.

“The use of nuclear energy fluctuates little from year to year,” Simon said. “It’s likely that in 2013, fewer reactors were down for refueling than in previous years.” However, a few of the nation’s 100 reactors have recently closed for good, such as the San Onofre Nuclear Generating Station in Pendleton, Calif.

The transportation sector is using more renewable energy, specifically biomass that is converted to ethanol. “This has been going up over time,” Simon said. “We’re expecting the fraction of biomass in transportation to remain relatively steady.”

The majority of energy use in 2013 was used for electricity generation (38.2 quads), followed by transportation, industrial, residential, and commercial. Energy use in the residential, commercial transportation, and industrial sectors all increased slightly.
