Renewable Energy | Department of Energy
Renewable energy comes from unlimited, naturally replenished resources, such as the sun, tides, and wind. Renewable energy can be used for electricity generation, space and water heating and cooling, and transportation. Non-renewable energy, in contrast, comes from finite sources, such as coal, natural gas, and oil.

Electricity Storage and the Renewable Energy Transition
The optimal storage power capacity substantially increases compared to the 60% case, and the storage energy capacity increases even more, such that the E/P ratio more than doubles. This is because the renewable surplus not only increases overall, but individual renewable surplus events also become much larger.
More than 60% of energy used for electricity generation is lost in conversion
In 2019, U.S. utility-scale generation facilities consumed 38 quadrillion British thermal units (quads) of energy to provide 14 quads of electricity. Most of the difference between these values was lost as an inherent result of the energy conversion process. The U.S ...
