Nevertheless, there are disadvantage of natural gas. To start with, natural gas cause greenhouse effect up to 20 time more potent than carbon dioxide. In larger applications, Gas from the landfill will not be able to meet the demand. If the extraction of methane is incorrect, Methane is released into the atmosphere. That will leave many toxic substances released into the atmosphere. Drilling and production, natural gas can lead to leakage of methane gas. Methane gas may be the natural gas leak was kept. For example, the compression from the transport. Natural gas is extremely volatile and may be harmful, if the shipment is not effective.
