Report: Hybrid cars could be more eco-friendly with renewable electricity
The benefits of plug-in hybrid cars may depend on changes in the electricity system to be witnessed in the coming years, according to PhD students at Carnegie Mellon University.
CarbonFree reported this week that a recent article published in the journal Environmental Science and Technology urged the electricity industry and governing bodies to step up the deployment of low-carbon electricity generation to power the vehicles.
Mr Samaras, a PhD student and author of the report said: "The types of power plants installed in the next two decades will not only affect how much we can reduce emissions from electricity, but also from vehicles if we plan on plug-in hybrids playing a substantial role."
His colleague Kyle Meisterling added that although plug-in hybrids produce fewer greenhouse gas emissions than gasoline-powered hybrids, their environmental impact could be improved even further by using electricity that is generated from carbon friendly sources.
Hollywood A-listers Cameron Diaz and Leonardo DiCaprio are reportedly fans of the Toyota Prius hybrid car.
