1. Electric Vehicles are quiet:
Your first-time experience driving an EV is almost disturbingly quiet. The electric motors of EVs are engineered to make almost no noise; the only sound you can hear is the muffled hum of tires on the road. On the other hand, the noise level inside a gasoline-powered vehicle can reach an uncomfortably loud 75-80 decibels4.
2. Electric Vehicles are more energy efficient:
EV converts chemical energy to electrical energy at a rate of 90% efficiency.1,5
The U.S. Department of Energy estimates2 that the conventional internal combustion engine loses 62.4% of its fuel energy as heat; after the energy lost to friction and aerodynamic drag, only 15% of the energy stored in the gas tank is used to move the car. EV batteries convert chemical energy to electrical energy at a rate of 90% efficiency1,3.
3. Low maintenance cost:
Electric cars do not require oil changes, because there is no oil used to run the engines. The same goes for fan belts, air filters, spark plugs or any of other parts that need periodic replacement for a gasoline car. Even the brakes on an EV can last longer than a gasoline car because an EV can slow the car by reversing the electrical motor instead of applying mechanical friction with brakes.1,6 This “regenerative braking” actually charges the battery and extends the range of the EV! The major component of an electric car – the battery – has high durability, too. Both Nissan and Chevy are offering 8 year/100,000 miles warranties for the LEAF and Volt batteries. 1, 6
4. Electric Cars have zero emissions.
EVs, being zero-emission vehicles, have no tailpipe, because they have no heat or gases to release as a byproduct of combustion. 1, 6 In theory, EVs are not truly zero-emission because of the pollution comes from the electricity to charge the EV battery. However, an EV produces 35-60% less carbon dioxide emission from electricity than the CO2 pollution from the gasoline of a conventional car with an internal combustion engine.5 The Department of Energy estimates that a gasoline car emits 75 lbs of CO2 during a 100 mile trip, in comparison to 32 lbs of CO2 emissions from a power plant to generate enough electricity to power an EV for the same 100 miles.2 In areas that rely largely on renewable power such as solar, wind or hydro, the emissions are even lower for EVs.
The Fairfield EV Showcase
The showcase, to be held Saturday, September 9, from 10 am to 2 pm at the Fairfield commuter parking lot at 140 Mill Plain Road (across from the Parks and Recreation Department), will bring together local car dealers, electric car club members, many local EV owners and the public to view the newest EV models and learn about the current state of the technology.
