Last year when I went to Disney, I had asked one of the cast members there and she said that she really wasnt sure but she thought there had to be over 50,000 people who work for disney. Walt Disney World Employees.
Methane is just used as a fuel for a gas turbine (can also be used to drive an internal combustion engine coupled to a generator). The turbine is coupled to a generator, which generates electricity.
Methane has both natural and anthropogenic sources. It is produced wherever organic matter decays under conditions where oxygen is lacking. This is the case, for example, in wet rice fields, in waste deposits, and in the stomachs of cattle and of termites.
