How Hybrid Cars Help the Environment
1. Reduction in Ground-Level Ozone
City smog contains numerous pollutants, mainly from our car tailpipe emissions, particularly when the car engine is idling in traffic. The main component is ground level ozone, which is formed by car exhaust emissions of carbon monoxide, nitrogen dioxide, sulphur dioxide and micro dust particulates.
The sun’s rays act on these noxious gasses and produce the ozone, which is particularly dangerous to young children, people with respiratory problems such as asthma, and the elderly.
Ground level ozone can also transfer to rural areas where it damages agriculture and vegetation.
Hybrid cars drastically reduce the exhaust emissions which cause the low level ozone in our cities, up to 90% less emissions of that from conventional cars.
They achieve this by the almost exclusive use of the electric drive motor in city driving, which emits no noxious fumes.
2. Reduction of CO2 Emissions in Rural Driving
Gasoline and diesel typically contain over 2000 grams of carbon in a gallon of fuel, and after combustion, is emitted as CO2 from the car exhaust, CO2 being a major component of Greenhouse gasses.
The innovation of the catalytic converter in the exhaust removes nitrogen and unburned hydrocarbons from the exhaust, but unfortunately, the CO2 passes into the atmosphere.
The hybrid car uses its finely tuned economical engine in the rural cycle, emitting much less CO2 gas.
When climbing hills, accelerating or overtaking it uses the electric motor as well as the engine. This reduces the load on the engine (a conventional car would produce more CO2 under these conditions) thus reducing the CO2 emissions.
3. Mitigation of Air Pollution Through Savings in Energy
The combination of all the innovative efficient energy saving components integrated into a modern hybrid car results in using less fuel than a conventional car. This leads to a higher MPG, saving energy and producing/releasing less polluting exhaust emissions into the atmosphere.
