3,975,096 people are employed in the solar industry worldwide, and 263,883 of these are in the United States. The solar energy industry created more new jobs in the US than any other energy subsector last year. It would take around 18.5 billion solar panels to produce enough energy to power the entire US. What is the capacity of solar energy?
Renewables as a whole contributed 38% of overall electricity generation (according to Ember Climate), and solar accounted for 11.5% of total renewables (see below). This gives an overall figure of 4.37%. In the US alone, the figure is slightly lower. The latest data shows solar producing 3% of total US electricity in 2020.
3.2 million US homes have solar panels installed. 3,975,096 people are employed in the solar industry worldwide, and 263,883 of these are in the United States. The solar energy industry created more new jobs in the US than any other energy subsector last year.
