What is Hydrogen economy?
A '''hydrogen economy''' is a [[hypothesis|hypothetical]] [[future]] [[economy]] in which the primary [[energy]] used for [[automobile]]s and other [[vehicle]]s as well as creating [[electricity]] comes from [[hydrogen]] and [[renewable energy]] sources, like windmills and [[solar panel]]. == Purpose == The reason to use this is to replace the use of [[oil|petroleum]]. It would also stop the use of [[fossil fuel]]s which causes [[carbon dioxide]] along with many other greenhouse gases, such as [[carbon monoxide]] and [[methane]], to be created. These float up into the [[atmosphere]], damaging it. This is bad for the [[ecology]]. {{physics-stub}} {{Emerging technologies}} [[Category:Hydrogen]] [[category:Energy]] [[Category:Sustainable development]]
