By the time electricity reaches your outlet, around two-thirds of the original energy has been lost in the process. This is true only for “thermal generation” of electricity, which includes coal, natural gas, and nuclear power. Renewables like wind, solar, and hydroelectricity don’t need to convert heat into motion, so they don’t lose energy.
The Energy Information Administration euphemistically describes these energy losses as “a thermodynamically necessary feature” of thermal electricity generation. But as the world looks to re-shape the energy supply, major losses of energy are neither necessary nor a feature of modern electricity.
Transmission and distribution cause a small loss of electricity, around 5% on average in the U.S., according to the EIA. The longer the distance traveled, the more the loss of electricity from transmission lines, and this energy loss is the same no matter what type of energy feeds into the grid.
The Energy Information Administration lists the heat rate for different types of power plants, and the average operating efficiencies of thermal power plants in the U.S. in 2020 were: Natural gas: 44% efficient, meaning 56% of the energy in the gas was lost, with 44% of the energy turned into electricity. What about the efficiency of renewables?
This is true only for “thermal generation” of electricity, which includes coal, natural gas, and nuclear power. Renewables like wind, solar, and hydroelectricity don’t need to convert heat into motion, so they don’t lose energy. The problem of major energy losses also bedevils internal combustion engines.
The technology and the type of fuel used to generate electricity affect the efficiency of power plants. For example, in 2019, of the 11.9 quads of natural gas consumed for electricity generation, natural gas plants converted 45% (5.4 quads) into net generation of electricity.
