On average for the United States and around the world, each widespread transition from one dominant fuel to another one takes 50 to 60 years. First, it was from wood to coal, then from coal to oil. This will be the third major energy transition for the U.S. from oil and coal to natural gas. From 2001 to 2012 the U.S’s coal consumption fell by 20 percent, oil declined by 7 percent and natural gas consumption increased by 14 percent. However, it will still be another decade or two before natural gas completely replaces coal consumption, which currently generates more than a third of America’s electricity. A transition to renewable energy can be difficult for numerous reasons. First we can simple evaluate the scale. The global use of fossil energies were about 1x10^18 joules in 2012, that’s 20 times greater than it was in the 1890s, as coal overtook wood. Generating this much energy with any new source is intimidating, and a significant amount of it will derive from the United
