Just as the Romans abused wood energy and then had to go solar, we need to search and find economically viable alternatives Supply and demand 90% of all usage is from non-renewable sources such as coal, natural gas, petroleum or soil and 10% from renewable sources such as hydro or nuclear power Our new energy policy still depends on the non-renewable fossil fuels Energy consumption has increased in the last decade due to low oil prices History 1950 to 1974 saw a big increase in energy usage in United States from 30 to 70 exajoules. Since 1908 it has only increased by 15 exajoules. The reasons for this are energy conservation and energy efficiency Formation of coal Plants decompose in oxygen-deficit environments and form peat Peat gets buried by sea level rise and sediment deposition to deeper depths The pressure of overlying sediment layers squeezes the water, organic gases and volatile out and percentage of carbon increases. This forms coal increases....
