Turbines

Biofuels are

Renewable bio

Biofuels are collected all sorts of different ways, but how is ethanol (specifically) produced?

Fermentation of plant sugars

These are sandy deposits permeated with bitumen

tar sands

cleaner than fossil fuels.  Ethanol and biodiesel are examples

biofuels

This energy source uses Earth’s internal heat as heat, or for electric generation

geothermal

This accounts for 28% of the energy used in the United States

transportation

This method of petroleum recovery relies on water to push up oil

secondary

This is a kerogen-bearing sedimentary rock

oil shale

This resource releases little sulfur when burned, has a higher net energy yield than other fossil fuels, and can be extracted and used without refining

natural gas

This type of methane forms when methanogens break down decomposing matter

biogenic

This is a waxy material found in oil shales that yields oil when the shale is heated and distilled

kerogen

hese energy resources started forming a long time ago from the partially decayed remains of plants and animals

fossil fuels

This method of petroleum recovery relies on superheated steam and surfactants to push oil up
