Electric Cars Are the Future of Personal Transport – Guess Why?
10 years ago electric and hybrid cars would make people giggle at their very mention. Yet these prototypes were nothing short of the human brilliance paving the way for what is soon to become the future of road transport. Electric vehicles are not a fashion trend, they represent the next revolution in automobile technology. It’s not so hard to see why there is such a hype about electric cars. Here are some of the points:
Electric motors by design are much more efficient than Internal Combustion Engines (ICE). They achieve efficiencies of well over 90% compared to an average of 20% for ICE. This translates into greater economical incentive since electric motors average 6Km/Kwh (Kilometer per Kilowatt-hour of energy) compared to 2.5Km/Kwh for ICE running on petrol. Efficiency with ICE is a big problem as there is not much scope for improvement. You see, in physics the laws of thermodynamics come into play theoretically limiting the efficiency of these designs to about 40%.
