Document Summary
Tidal energy (gravitational effects of moon and sun) All energy available for human use is tied to this energy cycle. Non-renewable resources supply over 90% of the world"s energy (primarily fossil fuels) During use, approximately half of the energy available is lost due to inefficiencies. In developing countries, the rate of energy use is increasing the fastest. North americans are the biggest per capita users of energy in the world. Averaged out, 2. 7 metric tons of coal for every living person on earth. Energy resources formed from organic matter that is buried by sedimentary processes. Altered by heat, pressure and the activity of microorganisms at depth. Deposition of vegetation in bogs and swamps (sources of organic carbon) forms peat. Burial must be rapid enough to prevent the oxidation of organic carbon (material can"t erode away) If there is sufficient pressure, temperature and time, peat turns into different grade of coal.
