The significance of a plug-in hybrid electric vehicle (PHEV) is, more than anything, its contribution to environmental sustainability. Plug-in hybrids are proven to emit less greenhouse gases and reduces oil dependency in vehicles. In numbers, it consumes an estimate of 30 to 60 percent less petrol than conventional vehicles. That said, with the world feeling the effects of climate change more than ever in recent decades, it is no wonder that more and more car brands have been shifting to non-gasoline engines. In fact, most highly developed countries have already begun to commit to a transition to full electric in the next 20 or 30 years.
