The Hidden Giant #2: Transportation
Well, this may not be a hidden issue, but I think it is a highly under represented issue. Transportation is the leading contiributor to greenhouse gases (GHGs) in the country, according to a report by the U.S. Department of Energy (DOE), and is also the fastest growing contributor, at a time when we are supposed to be making a U-turn in our GHG emissions.
When we talk about addressing global climate change, the talk is often about greening our homes, changing our source of energy, and cleaning up industry.

Starting from Detroit and heading to San Francisco, the vehicles developers are seeking to draw attention to an overlooked fuel alternative. The truck uses a special fuel, something widely available throughout the country, but until now, not widely considered as a fuel for transportation: the truck is carrying three tanks of ammonia in its bed.
