Why EVs & PHEVs (and not hydrogen, biogas, ethnanol, natural gas, etc.)?
SCD.Com supports all “green” technologies. But some are more green than others. Hydrogen-powered cars capture the imagination of many people, and, at the tailpipe, they are zero emission vehicles (ZEVs). But they have a major downside: it takes a tremendous amount of energy, which, of course, means fossil fuels right now, to create hydrogen. Ethanol suffers from the same problem, and, additionally, requires vast amounts of water to produce. Natural gas burns far cleaner than gasoline, but it requires extensive environmental destruction to harvest. It is also not a renewable resource. Biogas and biodiesel are attractive technologies. However, they still cannot boast the ZEV production of a solar-charged EV.
