The drive to reduce the dependency on non-renewable sources of energy has been the focus of most government agencies and private sectors in the global community. In the forefront of the battle to reduce the harmful emission of greenhouse gases is the automotive industry. Different car manufacturers are taking it upon themselves to develop new ways to decrease the emission of harmful gases by vehicles out in the roads of the world. There have been partnerships between car makers and companies in the alternative fuel industry too. And more recently, there are talks that Ford and Toyota will be joining forces to do battle against the global warming issue via the use of hybrid technology which will make their vehicles cleaner and safer for the environment.
