I work for a large electrical utility and at trade shows we have a bike that generates electricity.    Most people have trouble lighting a single light bulb.

In vermont, they have started a new program called "Cow Power" which generates electricity from cow poop.   I am not making this up.   As Yogi would say "you can look it up"

My company is one of the largest bio mass producers in the world.   We have 37 plants which make 75 Mega watts of electricity from landfills.   A mega watt is a million watts.   Biomass is a very viable form of energy and fairly economical when planned for in advance when building a landfill.

With cow poop and garbage, who needs electricity from humans.
