	Methane [[combustion]] (see simulation at bottom of page) provides a significant fraction of the world's [[primary energy]], and is used for [[home heating]], cooking food, heating [[water]], and [[electrical generation]]. It can even provide energy for [[transportation]]. However, this means that it is also a significant contributor to [[climate change]] since this methane produces a fair amount of the [[carbon dioxide]] that humans emit into the [[atmosphere]].
