Flashcards
Fractional Distillation
Fractional Distillation
A process that separates different components of petroleum based on their boiling points, resulting in products like diesel, octane, and other fuels.
Biomass
Biomass
A fuel source derived from organic matter, like wood, crops, or waste, that can be burned for energy.
Geothermal Energy
Geothermal Energy
A type of energy derived from the heat within Earth's core. It's a renewable resource as long as the Earth's core remains hot.
