A reader of EarthTalk posed an interesting question a few weeks back – does the expansion of electric and plug-in hybrid vehicles mean an increased reliance on coal?
Certainly if more and more of our sources of transportation utilize electricity instead of gasoline, that will increase the amount of electricity the United States uses. So where does that electricity come from? Looking towards the future there are two important benefits of shifting towards electric and plug-in hybrid vehicles. First, it decreases our reliance and consumption of foreign oil, which has multiple environmental, economic, and political benefits. Second, it sets up the potential for our transportation industry to be powered primarily with alternative energy.
Right now, though, the infrastructure is not in place to power our transportation industry primarily with alternative energy. That is not a problem now because there are not enough electric and plug-in hybrid vehicles on the road for this to be an issue. But what if the transportation industry grows faster than the alternative energy industry? Continue reading ‘Is Coal Expansion Imminent?’
