Key insights:

This NREL report provides clear evidence that Peak Demand no longer represents Peak Consumption

The 2018 Renewable Energy Data Book compiles the latest available statistics for the 2018 calendar year. Other key findings from the data include:

  • Overall U.S. energy consumption increased 3.5% (from 97.5 to 101.2 quadrillion British thermal units) between 2017 and 2018, the largest increase since 2010.
  • U.S. solar photovoltaic capacity increased by 20.6% (8.9 GW), accounting for more than 52.9% of newly installed U.S. renewable electricity capacity in 2018.
  • Wind capacity increased 8.4% (7.5 GW), representing more than 44.9% of newly installed renewable capacity in 2018.
  • Renewable-paired energy storage capacity in the United States expanded by 5.6% (76 MW) in 2018, up from a 2.4% increase in 2017.
  • U.S. natural gas-fired generation capacity accounted for 56.4% (21.8 GW) of all new U.S. capacity installed in 2018, accounting for a net addition of 15.1 GW after retirements.
  • Renewable energy generation as a percentage of total U.S. electricity generation remained unchanged—17.6% (741 TWh) in 2018.
  • The share of natural gas generation rose to 34.9% (1.468 TWh) from 31.9% in 2017.
  • Nearly 361,000 electric vehicles were sold in the United States in 2018 —an increase of over 84% from 2017—representing over 2% of total light-duty vehicle sales.

This latest edition includes a new section on the voluntary procurement of renewable energy in the United States; in total, some 966,000 customers procured 9.6 million megawatt-hours of renewable electricity through voluntary procurement mechanisms

Would love to see us get to the point we could measure that in GW like the rest rather than MW!

Richard, connections which send energy to the grid from batteries are equally capable of sending energy from the grid to charge batteries.

What evidence do you have that storage located near solar or windfarms is only storing clean energy? If it's storing a grid mix, it's making it 15-20% dirtier from losses (internal resistance, bi-directional inversion).
