The United States relies on renewables for approximately 20% of its energy needs. Only 2.8% comes from solar power, with 115 billion kWh of energy production. The other renewable resources are hydropower (6.3%), wind (9.2%), biomass (1.3%), and geothermal (0.4%).1
Despite that seemingly small number, 46% of all new electric capacity added to the grid in 2021 came from solar. That was a record, and the third year in a row for solar to be the largest contributor (40% in 2019, 43% in 2020).2
In 2021, 23.6 GW of solar capacity were installed. This brought the nation to 121.4 total GW of installed capacity, enough to power 23.3 million homes.3
Over 230,000 people are employed through the solar industry across all 50 states.4
Apple (398.3 MW), Amazon (369 MW), and Walmart (331 MW) are the top 3 solar consuming corporations as of 2019. They are closely followed by Target, Google, and other companies proving solar energy is becoming not only more popular, but more practical and affordable.4
The solar energy market in the United States is worth almost $33 billion as of 2021.4
There are over 3.3 million solar energy systems installed in the United States.4 Over 2.7 million of these systems are residential PV systems.5
With every system’s production accounted for, solar has effectively reduced 136 million metric tons of carbon dioxide emissions annually. This is equivalent to the reduction of gas consumption by 15 billion gallons, closing 34 coal-fired power plants, or planting 2 billion trees each year.4
In 2018, only 2.8% of solar panel systems also had an energy storage system. In 2021, the percentage jumped to 11.2%.
