Volume XI Issue III > Diesel Engines: Is Old Technology Actually Green Technology?

Fueling the Future

Diesel engines have been around for more than a century, but only now are we realizing their true potential. The diesel engine is no longer viewed as nothing more than a loud and polluting nuisance. With modern technology, the diesel engine has transformed into an efficient power source that can still be used in a time where we, as humans, have become more aware of the negative impact our behaviors are having on the environment. All of the technology being implemented in clean diesel engines is also relatively cheap. While diesel cars are more expensive than their gasoline-powered counterparts, they are cheaper than hybrid-powered vehicles. It is also feasible that a consumer will save enough money, through the improved gas mileage, to actually pay off the difference between a diesel-powered car and a gasoline-powered car. Also since diesel fuel and gasoline are relatively the same price, there will be no added cost to owning a diesel powered car over a hybrid car that can be attributed to fuel cost. With developing technology becoming greener and cleaner, diesel engine vehicles prove to be an economical choice.
