From an Oil Drum comment...the declining EROEI of coal... There was an interesting story about coal yesterday in the DrumBeat: heraldnet.com and it had this quote: To get a better picture of where we were two generations ago vs. where we will be in less than a generation, consider this: in the 1950s the ratio of energy returned in coal-burning power plants to energy spent in coal mining, transporting and processing was 30 to 1. This same ratio is now down to about 3 to 1. In the next 10 to 15 years, for the United States and much of the world, this ratio will be 1 to 1 and coal will no longer be a viable source of power.
