The concept of ‘energy transitions' is based on the notion that a single energy source, or group of sources, dominated the market during a particular period or era, eventually to be challenged and then replaced by another major source or sources.
(via Cutler Cleveland)
From Robert Bryce, “Wood to Coal to Oil to Natural Gas and Nuclear: The Slow Pace of Energy Transitions” (Aug., 2010)
Period I (pre-1820): dominated by human/animal power, wind-, wood-, and waterpower.
Period II (1820-1914): Industrial era dependent on wood, waterpower, and utlimately coal.
Period III (1914-9145): Oil emerges as a leading fuel; electrical power production dramatically increases.
Period IV (1945-1970s): A ‘postindustrial’ economy dependent on oil, punctuated by the 1970s ‘energy crisis.’
Period V: (1970s-?): Post-energy crisis America, still tied to carbon with some rumblings for change in later years.
The United States was blessed with abundant energy sources. Whether immediately exploitable or only potentially so, these sources were vital. Abundance affected the way Americans used energy, how businesses developed and marketed it, and how government established policies about it. While bestowing many benefits, the array of energy sources posed problems of choice. The luxury of choicewas preferable to the necessity to choose, but it often proved a curse when policy makers tried to arrive at coherent energy strategies. The energy history of the United States has been an ongoing effort to cope with abundance.
