Hybrid is less pollution than coal-powered Electric Vehicle

There’s study at Union of Concerned Scientist that average plug-in cars are less polluting than gasoline-powered vehicles in the US (okay, this is not really surprise_. But the greenhouse gases emitted from electic vehicles could pollute more than hybrid. The study centers on a heated discussion in auto circles. Many automakers referred electric vehicles as ‘zero emissions’ which misleading consumer because most plug-in drivers charge their cars from electricity generated by burning coal or natural gas. The Union of Concerned Scientist, clarify matters by doing a lifecycle analysis of greenhouse gas emissions that includes energy inputs from start to finish, not only during drive time.
It finds that charging an all-electric car equivalent to a car with a mileage rating between 31 miles per gallon to 40 mpg. Electric vehicles charged in areas with cleaner sources of electricity yields the equivalent of over 50 miles per gallon, better than the most fuel-efficient gasoline or diesel cars today. Driver can also lower their electric charging costs by taking advantage of off-peak rates or EV-specific rates.
The Union of Concerned Scientist analysis echoes previous studies in finding that on average, plug-in electric cars are less polluting than gasoline cars and cut oil consumption. It also underscores how fuel efficiency through hybrids or other efficient engine technologies can achieve significant gasoline reductions.
The study notes that projected increases in solar and wind on the grid means that the global warming emissions from an electric vehicle in those areas will decrease over time.
