Question

What is the capacity (in MW) of all states combined? What is the largest source/type of energy used to generate electricity in the country? What is the capacity of this particular type of energy (express in MW and as percentage relative to the total capacity)?

Answer 1

In 2019, the United States had a total electricity generation capacity equivalent to 1,100,546 MW—or 1.1 billion kilowatts (kW)—of total utility-scale electricity generating capacity and around 23 million kW of small-scale solar photovoltaic electricity generating capacity.

Natural gas was the largest source or type of energy used to generate electricity in the country.

The share of natural gas was 38% relative to total electricity generation capacity.

In MW:-

( 38 / 100 )* 1,100,546 = 418,207.48 MW.
