Extracting fossil fuel requires to build infrastructures, housings for workers, pipelines, mines, wells, storage tanks; once they are extracted, more energy is consumed by process, delivering. Usable energy required is divided by energy invested to acquire that usable energy. Fossil fuel energy return on investment is high so they are used more than other type of energy. The way fossil fuel was formed and stored was first through the sun energy. The sun energy was used and was converted to chemical energy through photosynthesis. When the organisms died, the chemical energy became concentrated and their hydrocarbon compounds (hydrogen and carbon dominate the organic material) were chemically altered. The carbon that was first stored in the biosphere (the organism) was now stored in the geosphere.
