Disadvantages

Limited quantity of natural gas

To be fully consumed by

2070

Higher operating cost

Highly inflammable

substance

- a colorless and an odorless substance, detection of gas leaks can be difficult- The process of extraction of natural gas involves making large cavities in the

ground. The cavities result in an increase in soil pressure and can cause the ground to sink

- Natural gas occupies four times the space of a gasoline-equivalent energy

Transport is costly
