Document Summary
Chapter 16: fossil fuels: energy use and impacts. Fossil fuels highly combustible substances formed from the remains of organisms from past geologic ages. Today we mostly use oil, coal, and natural gas. Fossil fuels are indeed formed from fossils: fossil fuels we burn today were formed from the tissues of organisms that lived 100 . 500 million years ago (carboniferous period: produced when organic material decomposed down in anaerobic conditions. Developed nations consume more energy than developing nations. Industrialized nations: use energy for transportation, industry, home/business and industrial needs, developing nations, use energy for subsistence activities, agriculture and food preparation, manual energy, animal energy, and biomass energy are more common than in industrialized nations. Coal is the world"s most abundant fossil fuel: coal = woody plant material, compressed and altered to form dense, solid carbon compounds, contains lignin, a tough organic constituent of plants, coal has a very long history of use.
