Natural gas vehicles (NGVs) offer a variety of economic and environmental benefits over conventional gasoline vehicles, but their adoption has been slow in most developed countries. However, according to a recent report from Pike Research, acceptance of NGVs is actually quite strong in other parts of the world. The cleantech market intelligence firm expects that, out of 11.3 million NGVs estimated to be on the road by the end of 2010, three-quarters of those vehicles will be in Latin America, the Middle East, and Africa.
