After a boom year for new natural gas plants, renewables set to retake the lead

In 2019, more renewable energy will be added to the grid than fossil fuel-based energy, according to estimates from the Energy Information Administration (EIA). That had been the trend between 2013 and 2017, but last year new natural gas-fired power plants outpaced renewable additions to the grid. As a result, US carbon emissions increased, notably from the power sector, despite the rapid retirement of coal plants and a growing consciousness about the necessity of low-carbon energy.
EIA expects 2019 to be a more modest year for new energy capacity compared to 2018, with only 24 gigawatts (GW) of total capacity additions predicted for 2019 compared to the 34GW of capacity additions predicted for 2018. In 2018, EIA predicted that 21GW of natural gas plants would come online, with roughly 11GW of new renewables coming online, making 2018 the first year since 2013 in which renewables didn't make up the bulk of the new capacity added in the US.
A recent report from the Rhodium Group shows that actual installations in 2018 track with the EIA's 2018 estimate: between January and October 2018, 14.9GW of natural gas capacity were added to the US grid, while only 7.9GW of solar and wind capacity were added. More power plants were likely turned on between October and December, and the ratio of natural gas to renewable installations is comparable.
