The EIA released the latest edition of their Electric Power Monthly on March 26th, with data for January 2019. The table above shows the percentage contribution of the main fuel sources to two decimal places for the last two months and the year 2019 to date.

In January, the absolute amount of electricity generated rose back to levels not seen since the end of summer in September 2018, probably as a result of the need for longer hours of lighting during the longer nights coupled with the increased needs for heating in the middle of winter. Coal and Natural Gas between them, fueled 61.49% of US electricity generation in January, with the contributions from Nuclear and Conventional Hydroelectric declining. The contribution from Natural Gas was up at 33.25%, from 31.71% in December, with the amount generated rising from 106,978 GWh to 118,935 GWh. Generation fueled by coal increased from 96,825 GWh to 101,019 GWh resulting in the percentage contribution falling from 28.70% to 28.24%. The amount of electricity generated by Nuclear plants increased from 71,657 GWh to 73,701 GWh with the resulting contribution actually declining from 21.24% to 20.60% in January. The amount generated by Conventional Hydroelectric increased from 23,728 GWh in December to 24,544 GWh in January with resulting contribution decreasing to 6.86% as opposed to 7.03% in December. The amount generated by Wind increased from 21,154 GWh to 22,493 GWh with the resulting contribution rising very slightly from 6.27% to 6.29% in January. The estimated total solar output rose from 4.962 GWh to 5,859 GWh with the resulting contribution rising from 1.47% to 1.56%. The contribution of zero carbon or carbon neutral sources declined from 38.59% in December to 37.41% in January.

The graph below shows the absolute monthly production from the various sources as well as the total amount generated (right axis).
