Document Summary
Us is increasing their coal use which is very alarming and when they increase this, it is likely that their renewable energy percentage will decrease. Usable amount of high-quality energy available from a given quantity of a resource. Total energy available - energy needed to find, extract, process and get it to consumers = net energy yield. Mixture of combustible hydrocarbons and some impurities. The boiling point of the oil is what determines what the oil will be used for. 12 opec countries - mostly in the middle east - have at least 71% of the world"s most proven oil reserves. The world"s peak production should be reached between 2010 and 2013 (some think it has already peaked) Uncertain when canada"s oil sands will peak. Once production peaks, supplies will begin to slow. Predictions say oil will last between 42-93 years depending on the rate of usage.
