Cars are considered green if they use less fuel energy to power the engine and their emissions from their tailpipe don’t cause greenhouse gases to form or cause illness. Some green car manufacturers are even taking the extra steps to produce green cars in facilities that use recycled materials and don’t use toxic substances in the production of the green car. The total package, fuel conservation, pollution free emissions, and non-toxic manufacturing facilities, reduces harm to the environment.
Consumer demand has prompted designers and engineers to more green cars. The technological advances made to make traditional gas guzzlers more energy efficient have paved the way for green cars. Fuel efficiency in cars and trucks has increased 50% in the last thirty years.
You probably can remember back when cars were getting 13 miles per gallon. Now, you would walk right passed a car salesman if he said something like that to you. Today green cars are getting 4 or more times as much per gallon. Green cars are even being designed with recycled plastics.
Even the body design of a car can make it more of a green car. The experts in aerodynamics design the cars to be streamlined. It saves gas which reduces the pollution coming from the cars – Something to do with less wind resistance. That one you will have to look up on your own. Before investing in green car technology, the manufacturers slipped backwards towards their old ways.
They put tons of research dollars into improving performance instead of keeping the research going towards energy efficiency. They wanted to make cars faster and add more amenities. That allowed you to drive to the grocery store at top speeds, barely missing pedestrians at corners, all while reclining in animal skin chairs. Now, green cars are here to stay. As technology develops, so will the performance in these cars.
Gas only cars may produce fewer pollutants than they did 30 years ago, but more people are driving than before so the pollution numbers don’t drop. The same amount of people can drive and the numbers can still increase, but if they were all green cars, the greenhouse gas emission would still be cut as much as 25 to 50%.
Green cars are possible by advances in transmissions over the years. Gone are the days when automatics had only three speeds. Today’s more advanced transmissions have 5 to 7 speeds. The difference between lower gears to the highest gear has been credited with increasing the fuel efficiency in cars up to 8% percent.
Also, now we have scientific tests being done on solar power cars and cars that can run off of vegetable oil. The inclusion of electricity systems and dual fuel hybrids are opening the doors to truly green cars or the future.
