fuel sources
What generates energy
Fuel sources are materials or phenomena from which energy can be extracted for power, heat, or propulsion.
The term encompasses fossil fuels like coal, oil, and natural gas, as well as renewable options such as solar, wind, and hydroelectric power.
Nuclear energy and biofuels also qualify as fuel sources.
The phrase typically appears in discussions of energy policy, environmental impact, or technological alternatives: We need to diversify our fuel sources to reduce dependence on foreign oil.
