What is methane?
Methane (CH4) is a naturally occurring gas. One of its major causes is the decomposition of plant and animal matter by methane producing bacteria. Methane is a very powerful greenhouse gas - 21 times more potent than carbon dioxide. It is produced naturally, but over the last two centuries its concentration in the atmosphere has more than doubled as a direct result of human activities, leading to serious concerns about its impact on global warming. The major man made sources of methane are natural gas extraction, waste disposal, livestock farming and coal mining.
What is propane?
Propane is a hydrocarbon (C3H8) and is sometimes referred to as liquefied petroleum gas, LP-gas or LPG. Propane is produced from both natural gas processing and crude oil refining, in roughly equal amounts. It is nontoxic, colorless and virtually odorless. As with natural gas, a strong identifying odor is added so the gas can be readily detected.
