Animals convert feed to work at an efficiency of about 5%, but while this was much more than the less than 1% efficiency of the early Newcomen engine, in coal mines there was low quality coal with little market value available. Fossil fuel energy first exceeded all animal and water power in 1870.

While renewable energy has undergone wide and rapid deployment, coal is still expected to be the main source of fuel for producing base load power in the near future. This is because coal reserves are expected to last for the next century and its cost is still relatively cheap. However, the emissions from coal combustion are a major environmental concern.

Energy efficiency is the amount of useful energy extracted from a system divided by the total energy put into a system. It may also be thought of as the efficiency with which we are capable of utilizing a resource. ... coal only supplies about 24% of the our energy needs. Coal usage worldwide is increasing due to high oil prices and ...
