In 2017, the US solar power generation reached 77000 GWh, biomass power generation capacity was 64000GWh, and solar power generation exceeded biomass energy generation for the first time. In renewable energy sources, only hydropower and wind power generation increased in 2017, 300000GWh and 254000GWh respectively. In recent years, the installed capacity of biomass power generation has remained relatively constant, while solar power generation has continued to grow.

The annual growth rate of solar power generation tends to lag behind the increase in annual installed capacity, because power generation capacity tends to increase at the end of the year. For example, in December 2016, the utility size of the solar power installed capacity increased by 29%, although the landing project has been included in the annual increment of the capacity of the power generation installed, but it still has a few days to contribute to the annual power generation. In 2017, solar energy accounted for 21% of the total in December. Overall, the annual operation of solar energy technology is lower than that of biomass energy technology, and the seasonal variation is even greater than that of biomass energy technology.


Biomass power has a variety of fuel sources, such as solid wood (68% of the total biomass of biomass in 2017), landfill gas (17%), municipal solid waste (11%), and other biological and non biological materials (4%). In recent years, the proportion of biomass power generation has been relatively stable.


Solar energy can be divided into three types: solar energy, which transforms sunlight into steam to generate electricity; large solar photovoltaic (PV) uses photovoltaic cells to generate electricity directly from the sun; small solar energy, that is, 1 megawatts or smaller photovoltaic devices. In recent years, the generation of solar thermal power has been relatively stable, about 3000GWh. The recent increase in solar thermal installed is the Crescent Dunes solar power plant installed in Nevada in 2015, and there is no building solar thermal generator set in the United States.


However, solar photovoltaic systems have been growing in recent years. In 2014, the large-scale photovoltaic system generated 15000GWh and the small photovoltaic system generated 11000GWh. By 2017, the annual output of these resources increased to 50000GWh and 24000GWh respectively. According to the initial monthly generator inventory data of the US energy information administration, it is estimated that by the end of 2018, 5067MW will be added to large PV. No information about small photovoltaic systems (1 MW and below) was collected in the survey.
