Of course, hybrid cars aren’t perfect; they still run on fossil fuel and so pollute the
environment to some extent. However, they may be the first step along the road to cleaner,
‘greener’ cars. Car manufacturers are already working on vehicles which run on hydrogen.
The only emission from these cars is harmless water vapour. These are still some way in the
future, though, as designers need to think of cheap and safe ways of producing, transporting
and storing hydrogen, but at last, it looks like we might be heading in the right direction.
