OREANDA-NEWS. April 11, 2017. Americans used more renewable energy in 2016 compared to the previous year, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory. Overall, energy consumption was nearly flat.

Each year, the Laboratory releases energy flow charts that illustrate the nation's consumption and use of energy. Americans used 0.1 quads (quadrillion BTU), more in 2016 than in 2015. A BTU, or British Thermal Unit, is a unit of measurement for energy; 3,400 BTUs is equivalent to about 1 kilowatt-hour.

The 2016 energy flow chart released by Lawrence Livermore National Laboratory details the sources of energy production, how Americans are using energy and how much waste exists.

Prices for photovoltaic panels have fallen dramatically over the past decade, contributing to solar energy's rapid growth, which rose by 0.15 quads or 38 percent in 2016, with significant additions in the electricity, commercial and residential sectors. "Two thirds of that increase was in the electric sector," said A.J. Simon, group leader for LLNL's energy program. "These are large installations of thousands of solar panels, usually in the desert." Installations on the roofs of homes and warehouses account for the rest of the additions.

Likewise, more wind power is contributing to the nation's utility grid. Use of wind power rose by 19 percent or 0.33 quads. "Generous incentives for renewable energy, combined with improved 'know-how' in siting and building wind farms, has led to a favorable environment for growth in this sector," Simon said.

Coal use decreased by 9 percent to 14.2 quads, mostly due to decreased coal supply to the electricity sector. That supply has been replaced by wind, solar and natural gas. Overall, natural gas use rose by 1 percent to 28.5 quads.

Energy use in the residential, commercial and industrial sectors all declined slightly, while consumption of fossil fuels in the transportation sector rose by 0.5 quads or 2 percent.
